Brucella canis is one of the many causes of discospondylitis in dogs, and the disease requires specific care. Little is known about the epidemic situation in Europe. The aim of this study is to gain an understanding of the brucellosis situation in dogs in Europe. Databases of European animal laboratories were searched for Brucella positive samples. In addition, the medical records of veterinary hospitals in Germany were analyzed for the diagnosis of discospondylitis and brucellosis. The laboratory received samples from 20 European countries for Brucella testing in dogs: 3.7% of samples submitted were Brucella spp. Positive PCR antibodies (61/1, 657) and Brucella canis were detected in 5.4% of samples (150/2, 764). Brucella spp. PCR-positive samples came from Spain (11.1% of included samples), Poland (6.7% of samples), and rarely from Italy and France. Samples containing Brucella canis vaccine come from 13 European countries (Sweden, Belgium, Austria, Switzerland, Italy, Finland, Germany, Denmark, Hungary, Norway, Poland, France, Netherlands). Young dogs (0-24 months) have a 5.4 times higher risk of obtaining PCR positive samples. A further medical record search identified four puppies (7-30 months) with Brucella canis discospondylitis in Germany. The four dogs were imported to Germany from Eastern European countries (Moldova, Romania, Macedonia). Finally, it is important to consider the disease and Brucella canis in European dogs, and the diagnosis of Brucella canis occurs in young dogs with discospondylitis.
Vs Form 4 33 Brucellosis Test Record
Back pain in dogs is often diagnosed by neurologists. How back pain is diagnosed is discospondylitis. The most common etiologies of discospondylitis in dogs are Staphylococcus species, and less commonly Streptococcus species, Escherichia coli, Aspergillus species, and Brucella canis or Brucella suis as well. Current diagnosis is based on X-ray of the spine, CT or MRI, blood cultures and needle probes of the disc cavity created by fluoroscopy or CT. Special methods are needed for the diagnosis of Brucella discospondylitis (1-3).
Molecular Recognition Of Brucella A And M Antigens Dissected By Synthetic Oligosaccharide Glycoconjugates Leads To A Disaccharide Diagnostic For Brucellosis
Brucella canis (B. canis) is a gram-negative, facultative intracellular coccobacillus that has been reported in many regions of the world and is considered endemic in the southern US, Central and South America, and Mexico (4-8) . B. canis also occurs in Canada (9). Outbreaks of B. canis have also been reported from Asia (China, Japan, India) and Africa (Nigeria, Zimbabwe) (5, 10–13). It is rare in Australia and does not occur in New Zealand (14-16). In Germany, B. canis was reported in 1976 in Beagle dogs (17) and in 2003 in a male dog with epididymitis and orchitis (18). Rare cases come from other European countries, such as Sweden (19, 20), the United Kingdom (21, 22), Austria (23), Italy (24), and Hungary (25). Countries with large populations of stray dogs are generally assumed to have large epidemics because stray dogs may contribute to the distribution and retention of this disease in dogs (6, 13, 26, 27). Partners, reproductive areas are also at a higher risk of maintaining the disease as well (28).
B. canis discospondylitis is the most commonly reported manifestation outside the body (24, 29-33), others are generalized lymphadenopathy (19), intraocular inflammation (34, 35), and osteomyelitis minor (36) and meningoencephalitis (37). . appearance like neurobrucellosis in humans (38). The most common causes of B. canis infection in dogs are early pregnancy, stillbirth, and inability to conceive in females (8, 19, 39, 40) and epididymitis, orchitis, prostatitis, and infertility in male dogs (24, 29, 41). Puppies can be born, with a high risk of stillbirth (37). Of concern is that B. canis can cause long-term infections and shedding of the bacteria (42, 43). Awareness of canine brucellosis as a zoonosis has increased in recent years (7, 44, 45), although human transmission is thought to be low (46). It is possible to transmit B. canis from dogs to humans. Immunosuppressants are closely associated with infected dogs (44, 47, 48), and laboratory workers also use the disease as a risk factor for infection (46, 49-51). However, surveillance of brucellosis as a zoonotic disease has often focused on B. melitensis, B. suis, and B. abortus (52-54). B. canis is largely ignored in Europe, although dogs often live close to their owners.
The aim of this study is to gain an understanding of the incidence of Brucella canis in dogs in Europe.
We searched European laboratory databases for Brucella positive samples. In addition, the medical records of German veterinary hospitals for dogs with Brucella canis discospondylitis and their origin were analyzed.
Brucella Spp. Of Amphibians Comprise Genomically Diverse Motile Strains Competent For Replication In Macrophages And Survival In Mammalian Hosts
The database of the veterinary diagnostic laboratory (IDEXX laboratories, Ludwigsburg, Germany), which was received from dogs for B. canis tests in 20 European countries, was analyzed (2011–2016). The laboratory received 4,421 samples from dogs for testing for Brucella infection: 1,657 were applied for the diagnosis of Brucella spp. and polymerase chain reaction (PCR), and 2,764 samples were sent for the detection of B. canis antibodies. Four samples were qualified as being from the same two dogs (Supplementary Tables 1–3). Checks are submitted by veterinarians or dog breeders. Polymerase chain reaction is a real-time PCR (IDEXX RealPCR™), which amplified the 76 bp sequence of the spacer region of Brucella spp. IDEXX RealPCR™ detects B. canis, B. microti, B. melitensis, B. abortus , B. suis and B. ovis. The process is not completed. The agglutination test was performed routinely (Institute of Animal Hygiene and Infectious Diseases, JLU Gießen, Gießen, Germany). The strain B. canis RM 6/66 was used as antigen. When grown on tryptone soy agar plates in 5% CO
Cultured bacteria were harvested for 48 h at 37 °C and suspended in 0.15 M phosphate-buffered saline (PBS) (pH 7.2). The suspension was filtered through four gauze pads and heated in a water bath at 56°C for 90 minutes to inactivate the microorganism. After washing the bacteria twice in PBS, the final pellet was suspended in the same buffer at approximately 10 times the concentration required for the agglutination assay. Merthiolate (final concentration 0.01%) was added as a preservative. For the agglutination test, the antigen was incubated with 0.15 M NaCl giving a McFarland turbidity no. 5. Each dilution (0.5 ml) of the log 2 dilution method with 0.15 M NaCl, starting at 1:25, of field sera taken with the same volume of antigen suspension to give the final serum dilution of 1:50 and then added for 48 hours at 37 °C in a humid environment. The recovery value of the final dilution that still reveals at least 50% B-cell agglutination is recorded as the titer. Known negative (field sera) and positive dog sera were used as controls. The latter were from experimentally infected B. canis dogs. According to Carmichael and Greene, a titer of 100 was chosen as the cut-off value (43, 55, 56).
The following data were obtained from the laboratory’s database: They were provided for diagnostic tests for B. canis infection, requested for diagnostic tests (B. canis antibodies, Brucella spp. PCR), diagnostic tests for B. canis antibodies . kennel. canis (presence, absence), Results of diagnostic tests for Brucella spp. PCR (positive, negative), sample country, sex and age of the dog. The frequency of positive PCR samples and the frequency of positive B. canis antibodies were calculated as a percentage of all samples submitted for each country. The confidence interval (CI
; Calculations according to Abraham Wald) calculated in excel (Microsoft Office Standard 2013) as follows:

[n: total number of samples tested; P: proportion of samples with positive test results (%). The strength of the association between positive PCR or the presence of anti-sex and age is estimated by calculating odds ratios (OR). Odds ratio and 95% CI excluding 1 were calculated to indicate a significant association at the 5% level.
As a secondary study, medical records of neurological function in a German veterinary hospital for dogs diagnosed with discospondylitis and Brucella canis infection were analyzed. Data were extracted from research studies, travel reports and the origin of the dogs (Table 4).
The European Veterinary Laboratory received 4,421 samples from 4,419 dogs for testing for canine brucellosis over a 5-year period (Table 1). Samples sent to the laboratory for Brucella spp. PCR from 15 European countries. PCR was positive in 3.7% (61/1, 657) of all included samples. Brucella spp. PCR positive samples were from four European countries: Spain, Poland, Italy and France (Figure 1A). The proportions for each country are described in Table 2. Young dogs (0–2 years) had a 5.4 increased risk of being PCR positive (OR 5.4; CI).
0.1–0.5). Statistical analysis did not show a correlation between dog sex and positive Brucella spp. PCR. Samples sent to laboratories for B. canis antibody testing came from 20 European countries. The presence of antibodies was recorded in 5.4% (150/2, 764) of all included samples. Samples containing B. canis vaccines from 13 European countries:
