Thirty-five serum samples and six hygroma fluid samples were collected from sexually mature cattle in one herd with clinical signs of brucellosis (abortion and hygromas) in the Western Region of the Gambia in order to isolate and characterise Brucella species. Information on the sex, age, number of calvings, number of abortions, presence of hygromas, and presence of orchitis was also collected for each animal sampled. Twenty-six (74 per cent) of the serum samples were positive in the rose bengal test and 29 (83 per cent) were positive by indirect ELISA. Three isolates of Brucella, biotyped as Brucella abortus biovar 3, were cultured from six hygroma fluid samples. The multiple locus variable number tandem repeat analysis assay clustered the isolates as B abortus with the same profile for the three isolates, suggesting a common origin of contamination.

UI MeSH Term Description Entries
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
D002002 Brucella A genus of gram-negative, aerobic bacteria that causes BRUCELLOSIS. Its cells are nonmotile coccobacilli and are animal parasites and pathogens. The bacterium is transmissible to humans through contact with infected dairy products or tissue.
D002003 Brucella abortus A species of the genus BRUCELLA whose natural hosts are cattle and other bovidae. Abortion and placentitis are frequently produced in the pregnant animal. Other mammals, including humans, may be infected. Bacterium abortus,Brucella melitensis biovar abortus
D002007 Brucellosis, Bovine A disease of cattle caused by bacteria of the genus BRUCELLA leading to abortion in late pregnancy. BRUCELLA ABORTUS is the primary infective agent.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005714 Gambia A republic in western Africa, constituting an enclave within SENEGAL extending on both sides of the Gambia River. Its capital is Banjul, formerly Bathurst. Republic of the Gambia

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
