EUROIMMUN AG About us The company · Global business For more information on this subject scan the QR code or enter the Quick Link code q109 at www.euroimmun.com The company EUROIMMUN is one of the leading manufacturers of medical laboratory diagnostics worldwide and stands for innovation. Over 2500 employees in 15 countries develop, produce and sell test systems for the diagnosis of diseases, and software and automation solutions for the performance and evaluation of these assays. Laborato‑ ries in over 150 countries use EUROIMMUN products for the diagnosis of autoimmune and infectious diseases and allergies, and to perform genetic analyses. The company was founded 1987 from the University of Luebeck (Schleswig-Holstein, Germany). As of December 2017, the US American company PerkinElmer, Inc. holds the majority of the EUROIMMUN shares. PerkinElmer is an international leader in the area of medical and biotechnol‑ ogy. The enterprise has its headquarters in Waltham, Massachusetts and has 11400 employees worldwide. With innovative detection and imaging techniques and IT systems, it provides comprehensive expertise in diagnostics, medical research and environmental and food analytics. PerkinElmer, Inc. is a component of the S&P 500 Index. EUROIMMUN has extensive know-how in the fields of immunology, cell biology, histology, biochemistry and molecular biology. The company is based on state-of-the-art, partly patented production processes and micro- analysis techniques. The great expertise in the development and production of human diagnostic products has led to the establishment of an own business division focusing on the development of veterinary diagnostic test systems such as IIFT, ELISA and line blots. Great expertise and ongoing training are essential for the use and distribution of EUROIMMUN products. Every year, the EUROIMMUN Academy receives almost 1000 customers from over 50 countries, providing train‑ ing for customers, field staff, and employees from all EUROIMMUN subsidiaries. Moreover, there are train‑ ing laboratories in several countries. The accredited Institute for Quality Assurance, an institution of the com‑ pany, organises quality assessment schemes and thus helps to maintain the high quality standard of exter‑ nal laboratories. The Institute for Experimental Immunology, another EUROIMMUN institution, is dedicated to basic research. The institute also cooperates with universities, clinics and renowned research institutions from all over the world. These cooperations have resulted in a large number of diploma and doctoral theses. EUROIMMUN is ISO certified (EN ISO 9001:2008, EN ISO 13485:2012, ISO 13485/CMDCAS). A large share of the company’s success can be attributed to the associated reference laboratory, which offers a fast and differentiated diagnosis to the EUROIMMUN customers and clarifies several hundreds of patient samples with difficult constellations every day. EUROIMMUN meets its needs for qualified personnel not only through its presence at recruitment and trade fairs and advertisements, but also through its own training program. Alongside the vocational school, the apprentices and trainees are offered a comprehensive practical and theoretical program and intensive mentoring in the work routine. At present, the company employs 75 trainees and more than 2500 persons worldwide. Women represent nearly 60 % of staff and thus the majority. 1080 employees have an academic background, 175 of them hold a doctoral degree. 6

Indirect immunofluorescence Detection methods EUROIMMUN IFT: unrivalled quality and diversity For more information on this subject scan the QR code or enter the Quick Link code q115 at www.euroimmun.com EUROIMMUN IFT: unrivalled quality and diversity Immunofluorescence tests from EUROIMMUN: high-tech, not old-fashioned! Numerous innovations contribute to the standardisation and modernisation of indirect immunofluorescence: Activation technique: Physically or chemically activated cover glasses are coated with cultured cells or tissue sec‑ Tissue sections tions. Frozen tissue sections are fixed to the glass surface by Antigen dots covalent bonding. This increases the adhesion by more than Cultured cells 100 fold, preventing detachment of the sections. Transf. cells BIOCHIP Technology: Cover glasses coated with biologi‑ cal substrates are cut mechanically into millimetre-sized fragments (BIOCHIPs). Ten or more first-class preparations of consistent quality can be obtained per tissue section, for cultured cell substrates even several thousands. BIOCHIP Mosaics: When multiple BIOCHIPs coated with dif‑ ferent substrates are arranged in one reaction field, antibod‑ ies against various organs or infectious agents can be inves‑ tigated simultaneously. Comprehensive antibody profiles can be easily established (multiplex) and the results are verified BIOCHIP Technology and Mosaics reciprocally on different substrates. TITERPLANE Technique: The samples or reagents are first pipetted onto the reaction fields of a reagent tray. The slides are then placed into recesses of the reagent tray, where all BIOCHIPs come into contact with the liquids, and the individual reactions begin simultaneously. As the fluids are confined in a closed space, there is no need for a conventional humidity chamber.

Line blots Detection methods EUROLINE: line blots for comprehensive antibody profiles For more information on this subject scan the QR code or enter the Quick Link code q118 at www.euroimmun.com EUROLINE: multiparameter line blots for comprehensive antibody profiles Uncomplicated test performance, reliable and simple evaluation: Quick: The total time for analysis is 115 minutes. All incubation steps are carried out at room temperature. Automatable incubation: with EUROBlotOne or EUROBlotMaster. Secure: The antigen lines are located at precisely defined positions. Correct performance of the individual incu‑ bation steps is indicated by staining of the control band contained on each EUROLINE test strip. The conjugates are colour-coded. Positive and negative results can be distinguished from each other reliably and easily. The intensity of bands correlates with the antibody titer. Monospecific: The antigens used are purified antigens, mostly isolated by affinity chromatography, or antigen extracts. The membrane strips do not contain superfluous proteins that may lead to unspecific positive results. Multiparameter analysis: The use of an antigen spectrum that is specifically tailored to the diagnostic require‑ ments increases the serological detection rate. Evaluation: The EUROLineScan program developed by EURO IMMUN allows standardised evaluation of EUROLINE test strips, easy data management and detailed documentation of results. First, the incubated EURO‑ LINE test strips are scanned by a flatbed scanner or photographed by a camera system. EUROLineScan recog‑ nises the position of the strips, even if they have been placed inexactly, identifies the bands, and measures their intensity. Finally, the results are saved together with the image data and a separate results sheet can be issued for each patient. EUROLineScan can be integrated easily into EUROLabOffice or any other LIMS for optimal data communication. b a -B -B l ro A A C 00 b sE sE bp sp sp nt 9 8 8 B p3 p5 p1 p1 Vl Vl Co L- O O D Borr GE 20

Infection diagnostics diagnostics Veterinary Anaplasma · Borrelia · Brucella · Ehrlichia · Leishmania · MERS-CoV · Toxoplasma · WNV · Tick-Borne Profile Anaplasma Clinical information: Anaplasma (A.) phagocytophilum is the causative agent of anaplasmosis, a bacterial dis‑ ease which is transmitted through bites from ticks of the genus Ixodes. A. phagocytophilum is a gram-negative, obligate intra-cellular bacterium which attacks mostly neutrophilic granulocytes, but also, in rare cases, eosino‑ philic granulocytes. Anaplasmosis occurs worldwide, its prevalence depending on the distribution area of the transmitting vectors. There are different names for the clinical picture of an infection with A. phagocytophilum in dogs: granulocytic ehrlichiosis (obsolete), canine granulocytic anaplasmosis, and, simply, and most frequently used: anaplasmosis. Clinical symptoms of canine anaplasmosis include a reduced general condition with fever, weight loss, vomiting, dyspnoe, spleno- and hepatomegaly, lymphadenopathy, oedema of the joints, leukopenia, anaemia, haemorrha‑ gia, polyarthritis and CNS symptoms as a result of inflammation and bleeding in the meninges. In some dogs the immune system is able to eliminate the pathogen, others show an asymptomatic or chronic course. In the chronic form, alternating lamenesses may occur due to polyarthritis. A. phagocytophilum infection in horses is also known under various names: granulocytic ehrlichiosis (obsolete), equine granulocytic anaplasmosis, and in most cases also: anaplasmosis. The clinical symptoms of equine ana‑ plasmosis are a reduced general condition with fever, anorexia, lethargy, oedema of the limbs, petechia, icterus, reluctance towards physical activity, and ataxia. Older horses show clearer symptoms than younger ones. Diagnostics: Antibodies against A. phagocytophilum occur in the serum of infected animals after seven to fourteen days. Different techniques are used for the serological detection of antibodies, such as ELISA or indirect immunofluorescence test (IIFT). It needs to be taken into consideration that many dogs and horses show specific antibodies against A. phagocytophilum but are not clinically conspicuous. For diagnosis, it is hence necessary to investigate two blood samples at a time interval. A twofold titer increase or a seroconversion are here diagnosti‑ cally relevant. If the first blood sample tests negative, a second sample should be examined after two weeks in cases of suspected anaplasmosis, since dogs and horses do not produce antibodies in the early phase of infection. Borreliosis should be excluded by differential diagnosis. As of yet, no vaccines are available for dogs or horses. 24

Infection diagnostics diagnostics Veterinary Anaplasma · Borrelia · Brucella · Ehrlichia · Leishmania · MERS-CoV · Toxoplasma · WNV · Tick-Borne Profile Borrelia Clinical information: Borrelia is the causative agent of Lyme borreliosis, a disease which is transmitted through bites from ticks of the genus Ixodes. The gram-negative bacteria are collectively referred to as Borrelia burgdorferi sensu lato. In this group, the genospecies Borrelia burgdorferi sensu stricto, Borrelia garinii and Borrelia afzelii are pathogenic for dogs and horses. Whereas in the U.S. only B. burgdorferi sensu stricto is relevant, more than 80 % of Borrelia in European ticks belong to the pathogenic genospecies B. garinii or B. afzelii. Dogs and horses have a significantly increased risk of infection because of their higher frequency of contact with ticks. Most of the infections, however, proceed asymptomatically. Infection does not confer strong immunity. Reinfection is therefore possible. Antibodies against B. burgdorferi can be found in the serum of specifically infected or vaccinated animals. An infection with B. burgdorferi is associated with a variety of clinical symptoms, which generally occur weeks or months after infection. Primary symptoms of Lyme borreliosis in dogs include lethargy, loss of appetite and fever and are therefore rather unspecific. The first more or less specific symptom in dogs is lameness due to myositis or arthritis, which generally occurs in a later stage of infection. Neurological impairments and damage to the kidneys (glomerulone‑ phritis) or heart (myocarditis) are rarely described. Various vaccines are available for dogs. Borreliosis in horses is characterised by arthritis, alternating lamenesses, algesic muscles, uveitis, encephalitis, miscarriage, fever and lethargy. A vaccine for horses has recently been brought onto the market. Erythema migrans, a characteristic sign of borreliosis in humans, is not relevant in either dogs or horses, since it cannot be seen through the fur or because of dark skin. Diagnostics: Diagnosis of canine or equine borreliosis is based on clinical symptoms, differential diagnostics and the detection of antibodies against Borrelia antigens. Some studies recommend a two-step strategy for the determination of Borrelia-specific antibodies. Firstly, a sensitive screening test (ELISA or IIFT) is used. Sera with a positive or borderline screening result are investigated further using an immunoblot to differentiate between Borrelia-specific and unspecific reactions. Since antibodies against Borrelia are first produced two to six weeks after infection, serological tests performed in the early stage of Lyme borreliosis can be negative. A follow-up sample taken after seven to ten days should therefore be tested in suspected cases. IgM antibodies against Bor‑ relia antigens can be found for a period of a few weeks in the early stage of infection. 26

Infection diagnostics diagnostics Veterinary Anaplasma · Borrelia · Brucella · Ehrlichia · Leishmania · MERS-CoV · Toxoplasma · WNV · Tick-Borne Profile Brucella Clinical information: Brucellosis is a zoonotic disease which is caused by gram-negative bacteria from the Bru‑ cella genus. Brucella is classified as risk group III by the WHO. In camels and bovines, different Brucella species have been identified, e.g. Brucella abortus and melitensis. Brucella can be transmitted to humans via fresh milk or raw meat and turn into a serious health problem in the affected regions. Human brucellosis is considered as the most widely distributed zoonosis, with 500,000 new infections per year. Transmission of the pathogen can be oral, but also venereal, congenital or perinatal. The economic loss due to miscarriage, decreased milk production, reduced fertility, and the transmission of the disease to other species, including humans, is significant. Infections in non-gestating bovines usually proceed asymptomatically, whereas in pregnant bovines the following symptoms or sequelae are observed: late abortion, retained placenta, subclinical mastitis, sterility and, in rare cases, tendinitis and joint inflammation. Male animals experience orchitis and epididymitis. Camels of the species Camelus bactrianus and Camelus dromedarius are often infected with Brucella, especially if they live in direct vicinity of infected ruminants such as cattle, sheep or goats. Entry sites for Brucella are the lungs, intestinal tract, mucous membranes and skin. Experimental infection of camels with Brucella abortus led to mild clinical symptoms, e.g. inappetence, minimal lameness due to arthritis, and bilateral lacrimation. Orchitis and epididymitis occurred with Brucella abortus and Brucella melitensis. Retentio secundarium, placentitis, infections of the urogenital tract, abortion with mummification, and infertility were also observed. Diagnostics: Reliable diagnosis can only be achieved by direct detection of Brucella in the affected tissue, e.g. from the placenta or lymph nodes. This procedure, however, is complicated, and also constitutes a potential infec‑ tion risk for the laboratory staff. For this reason, various serological test systems for the detection of antibodies against Brucella have been developed, including the complement fixation test (CFT) and Rose Bengal test (RBT). But these tests are time-consuming and limited with respect to sensitivity and standardisation. The RBT can only be used for monitoring in Brucella-free regions. The World Organisation for Animal Health OIE (“Office Interna‑ tional des Epizooties”) names various serological tests for the diagnosis of bovine antibodies against Brucella, including the above-mentioned CFT and RBT, as well as ELISA. However, the organisation also points out that a positive result should always be verified using a confirmatory test. ELISAs based on a large antigen spectrum offer a high sensitivity and are therefore ideally suited for screening. 28

Infection diagnostics diagnostics Veterinary Anaplasma · Borrelia · Brucella · Ehrlichia · Leishmania · MERS-CoV · Toxoplasma · WNV · Tick-Borne Profile Ehrlichia Clinical information: Ehrlichiosis is a disease which is transmitted to animals and humans by tick bites. It was first described in Algeria in 1935. Ehrlichiosis in dogs is mainly caused by the pathogen Ehrlichia (E.) canis, which is transmitted by the brown dog tick (Rhipicephalus sanguineus) and may lead to canine monocytic ehrlichiosis (CME). E. canis is a gram-negative, obligatory intracellular bacterium which mainly affects mononuclear blood cells. CME is a worldwide distributed disease in tropical and moderate climates. The geographical occurrence of E. canis is increasing with the proliferation of the tick vector due to the climate change. Canine monocytic ehrlichiosis in dogs is a multisystemic disease which may manifest in acute, subclinical or chronic forms. After an incubation period of 1 to 3 weeks an acute CME develops, which is characterised by high fever, lethargy, weight loss, lymphadeno- and splenomegaly and haemorrhages. Damage to the eyes occurs fre‑ quently, which may even cause blindness. Inflammation or bleeding in the meninges may cause different CNS symptoms. After 2 to 4 weeks, the subclinical phase starts. At this stage, the dogs appear generally healthy and without any obvious symptoms, even though high titers of E. canis-specific IgG antibodies and changes in the blood count can already be detected. Some dogs enter the chronic phase, in which the symptoms resemble those of an acute CME, but are more pronounced. Diagnostics: Direct detection of E. canis by staining or culture is possible, but is usually not performed since these methods are too complicated for screening diagnostics. Detection of typical cytoplasmic morulae in the monocytes by means of blood smears supports the diagnosis of CME. However, only a very small percentage of the clinical cases shows characteristic morulae, which makes the search difficult and time-consuming. Culturing of E. canis also requires much time and is therefore not suitable for routine diagnostics. PCR is regularly used for direct detection of Ehrlichia DNA. Here, quantitative real-time PCR should be preferred over conventional PCR due to its higher sensitivity. A decisive advantage of serological antibody detection is the possibility to determine E. canis-specific antibodies or the titer course. The latter is recommended for assessment of therapy success. 30

Infection diagnostics diagnostics Veterinary Anaplasma · Borrelia · Brucella · Ehrlichia · Leishmania · MERS-CoV · Toxoplasma · WNV · Tick-Borne Profile Leishmania Clinical information: Leishmaniasis is a zoonotic infection that is caused by protozoa of the Leishmania genus. Leishmania infantum, Leishmania chagasi and Leishmania donovani, which belong to the Leishmania donovani complex, are of particular importance. These monocellular parasites are transmitted to humans or animals via the bite of female sandflies of the genera Phlebotomus (Africa, Asia, Europe) or Lutzomyia (Central and South America). Dogs are considered as the most important reservoir. Due to the zoonotic potential, infected dogs are a major problem in veterinary and human medicine. It is assumed that 50 % to 80 % of dogs in endemic areas are infected with Leishmania. However, Leishmania infection is not synonymous with canine leishmaniasis. Less than 10 % of infected dogs show clinical symptoms. Certain dog breeds and the age of the dog are associated with a predisposition for the development of leishmaniasis. The immune response of the dog is also crucial for manifestation. Leishmania infections are characterised by long incubation times, which may be months to years. The various zymodemes of the individual Leishmania species can cause different clinical manifestations. In dogs it is often impossible to discriminate between visceral and cutaneous leishmaniasis because the visceral form is frequently accompanied by skin changes. The large variety of symptoms includes fever, weight loss, anorexia, various skin changes (e.g. dermatitis, hyperkeratoses, paw pad fissures), eye problems (e.g. uveitis, keratoconjunctivitis) and various organ problems (e.g. glomerulonephritis, hepato- and splenomegaly), diseases of the musculoskeletal system (e.g. due to polyarthritis) and changes in laboratory results (e.g. hyperglobulinaemia, hypoalbuminaemia, proteinuria). Clinical symptoms of canine leishmaniasis can improve or even subside with chemotherapy. How‑ ever, relapses are possible since the treatment does not allow complete elimination of the parasite. Vaccination against Leishmania is possible. Diagnostics: Diagnosis of Leishmania infection is generally based on serological tests (IIFT or ELISA) detecting Leishmania-specific IgG antibodies. High antibody titers correlate with clinical leishmaniasis or indicate a possible manifestation of canine leishmaniasis in infected asymptomatic dogs. Pathogen detection by means of PCR can help to establish a Leishmania diagnosis, but it does not allow conclusions to be drawn with respect to a clini‑ cal manifestation. Therefore, serological detection is the method of choice for diagnosing canine leishmaniasis. 32

Infection diagnostics diagnostics Veterinary Anaplasma · Borrelia · Brucella · Ehrlichia · Leishmania · MERS-CoV · Toxoplasma · WNV · Tick-Borne Profile MERS coronavirus Clinical information: Middle East respiratory syndrome (MERS) is caused by a previously unknown coronavirus (MERS-CoV). So far, all human MERS-CoV infections have originated in the Middle East. About 40 % of known cases were fatal. The incubation time ranges from less than a week in the majority of cases to up to 12 days in individual cases. Transmission between humans takes place via aerosols and smear infections. Respiratory secre‑ tions of the upper respiratory tract of infected persons play a particularly important role as they can be passed on by sneezing, coughing, and via contaminated hands. Camels are currently discussed as the potential source of sporadic MERS-CoV infections in humans. Antibodies against MERS-CoV were found in camel sera that had already been collected in 1983. This leads to the assump‑ tion that the virus has been circulating in the camel population for a long time. The antibody prevalence in adult camels in endemic areas is up to 100 %. In newborn camels, it is assumed that the virus is multiplied and shed, as time is needed to generate neutralising antibodies. During this time the calves might be a source of infection for humans. There is no approved vaccine available. Diagnostics: Clinical symptoms in camels infected with MERS-CoV are rare and generally mild. The most reliable laboratory diagnostic methods for confirmation of suspected MERS-CoV infections in camels include the direct detection of MERS-CoV using PCR and the detection of antibodies against MERS-CoV using indirect immunofluorescence (IIFT), ELISA, or neutralisation tests. Cross reactions with other coronaviruses, in particular bovine coronaviruses, need to be taken into account in serological diag‑ nostics. These can be reduced using a specific domain of the recombinant spike protein as the antigen in the ELISA. The IIFT based on MERS-CoV- Anti-MERS-CoV positive infected cells as the substrate provides a highly sensitive screening test that allows qualitative and semi-quantitative detection of antibodies against MERS-CoV. Positive results should be confirmed with another method, ideally by means of a neutralisation test. 34
