Brucellosis is an important bacterial zoonosis caused by B. abortus and B. melitensis in Pakistan. The status of canine brucellosis caused by B. canis remains obscure. In total, 181 serum samples were collected from stray and working dogs in two different prefectures viz. Faisalabad (n = 87) and Bahawalpur (n = 94). Presence of antibodies against B. canis and B. abortus/B. melitensis was determined using the slow agglutination test (SAT) and ELISA, respectively. Real-time PCR was performed to detect and differentiate Brucella DNA at the species level. In Faisalabad, the serological prevalence was found to be 9.2% (8/87) and 10.3% (9/87) by SAT and ELISA, respectively. Only one of the ELISA positive samples (1.15%) yielded amplification for B. abortus DNA. In Bahawalpur, 63.8% (60/94) samples were found positive by SAT; however, none of the samples was positive by ELISA or by real-time PCR. Location, age (≥1 year) and body condition (weak) were found to be associated with B. canis infection, whereas presence of wounds was found to be associated with B. abortus infection only. These findings point towards a risk of transmission from dog to livestock and humans and vice versa. The study expects to draw the attention of concerned authorities towards infection prevention and animal welfare. This study warrants further epidemiological investigation on brucellosis in pet dogs and their owners. To the best of our knowledge, this is first ever report on B. canis and B. abortus in dogs in Pakistan.

“…The fact that NMBM had the highest average age of dogs (43.4 months), as compared to 29.9 months in the CJM-Gauteng and 40.6 months in the T&O, explains why NMBM had a higher risk of B. canis infection compared to the other two study areas. These findings affirm previous work of other researchers who concluded that the age of the dog, especially in sexually active dogs above 3 years of age, presents a greater risk for B. canis infection (Ayoola et al 2016; Anyaoha 2015).…”

“…A serological study by Ayoola et al (2016) between 2011 and 2014 in the Lagos and Ogun states of Nigeria among hunting and stray dogs similarly revealed age to be a significant factor playing an important role in B. canis infection. The study found that dogs older than 3 years were more than six times more likely to be seropositive for antibodies for B. canis than dogs younger than 3 years.…”

The growing population of free-roaming dogs in informal communities in South Africa may increasingly place humans at risk of possible zoonotic infections including, but not limited to, Brucella canis. Worldwide, the prevalence of B. canis infection has increased during the last two centuries, resulting in increased reports of dog and human infections. This study investigated the risk factors associated with B. canis infection in dogs in three predefined areas: Gauteng, the Eastern Cape and Western Cape provinces, of South Africa. Dogs aged 7 months and older presented to welfare organisations and breeders in the study areas were selected for sampling. A comprehensive questionnaire on dog ownership, general health and vaccination status was completed prior to sampling. One blood sample of 8 mL was collected aseptically per dog. Then, equal amounts (4 mL) were transferred to the different vacutainer tubes. The 2-mercaptoethanol-tube agglutination tests were used after validation. Fifty-two dogs out of the combined sample of 1191 dogs from the three study areas tested positive for B. canis, representing an overall occurrence of 4.4%. A binomial logistic regression model was fitted to identify risk factors associated with B. canis in dogs within the study areas. Dog age (0.371; p < 0.05) and external parasite infestation (0.311; p < 0.05) were significantly associated with the B. canis infection. Ownership and sterilisation need to be further investigated as possible risk factors because both had odds ratios of 1684 and 1107, respectively, in the univariate model.

“…The highest seroprevalence of 56.82% and a prevalence of 3.2% are recorded in dogs 12 months and above using RBPT while the lowest 25.00 and 0.00% are recorded in dogs 0-6 months old. This report is in agreement with that carried out by Comfort et al 14 , where the highest prevalence of 9.8% was recorded in adult dogs. It is also in agreement with the works of Momoh et al 12 , where a prevalence of 30.3% was recorded in 12 months old dogs and above using RBPT.…”

Background and Objective: In veterinary hospitals in Nigeria's North Central Region, serological testing for brucellosis is Not a Common Practice (NCN). As a result, this study was carried out to find out how common brucellosis is in dogs in NCN. Materials and Methods: A total of 550 sera samples were collected from dogs presented to the veterinary clinics, dog kennels and dog breeder homes. The samples were analyzed using the Rose Bengal Plate Test (RBPT) which gave a prevalence of 239 (43.46%). Results:The result indicated the highest seroprevalence of 125 (56.82%) by RBPT for dogs 12 months old and above. This was followed by dogs aged 6-11 months with a rate of 79 (41.58%). The lowest seroprevalence 35 (25.00%) was recorded amongst dogs aged 0-6 months. Sex distribution of Brucella abortus among dogs in NCN indicated that female dogs had the highest seroprevalence of 185 (44.58%), while male dogs had the least percentage rate of 54 (40.00%). The seasonal distribution of Brucella abortus among dogs in NCN indicated that the highest seroprevalence of 165 (68.75%) was recorded in the wet season. The least percentage prevalence rates of 74 (23.87%) were recorded in the dry season. The result indicated the highest seroprevalence of 142 (59.66%) for local breeds of dogs. Mix-bred dogs had the least rate of 60 (26%). Exotic breeds of dogs however had a seroprevalence of 37 (43.53%). Based on management systems, the highest seroprevalence of 190 (53.37%) was recorded in dogs reared extensively and the least rates of 49 (25.26%) were recorded in dogs reared intensively. Conclusion: A cost-effective federal government policy on the control and eradication of this important zoonotic disease is indicated.
