Topic:Brucellosis
Brucellosis in horses is a bacterial infection caused by the Brucella species, primarily Brucella abortus and Brucella suis. Although less common in horses compared to other livestock, brucellosis can result in clinical manifestations such as lameness, abscesses, and reproductive disorders. Transmission typically occurs through direct contact with infected animals or contaminated materials. Diagnosis involves serological testing, bacterial culture, and polymerase chain reaction (PCR) methods. This page aggregates peer-reviewed research studies and scholarly articles that explore the epidemiology, pathogenesis, diagnostic techniques, and management strategies for brucellosis in equine populations.
Study of agglutinins to Brucella abortus, B canis and Actinobacillus equuli in horses. Horses at a veterinary teaching hospital and a slaughterhouse were surveyed for antibodies to Brucella abortus, B canis and Actinobacillus equuli. Four of the 141 hospitalised horses and none of the 73 slaughtered horses had titres of 1:100 or greater to B abortus. Six horses of both populations reacted to the card test. One was culture positive. A card test using B canis antigen was positive in 38 per cent of the sera from hospitalised horses and all of the slaughtered horses. Twenty (27.4 per cent) of the latter group had high tires in a tube agglutination test. High titres could not be redu...
Sero-epidemiologic investigations on brucellosis in the states of Uttar Pradesh (U.P.) and Delhi (India). Sero-prevalence of brucellosis in man and animals was studied during the years 1976 and 1977. Samples were collected from Hospitals/slaughter houses/livestock farms located in Delhi and different districts of Uttar Pradesh (U.P.). The sera samples tested were from 1685 men, 1607 goats, 438 sheep, 244 pigs, 361 cattle, 551 buffalos, 50 dogs, 318 equine and 43 free living animals. The percentage of seropositivity, excluding doubtful ones, was recorded as: man 0.89, goat 5.53, sheep 3.42, pigs 15.98, cattle 6.37 buffalo 4.9 and equine 12.89. Additionally an evidence of agglutinins was also detect...
A complement fixation test for antibody to the contagious equine metritis organism. A complement fixation test (CFT) based on that used for brucellosis (Brinley Morgan and others 1971) has been developed for use on the sera of horses exposed to the contagious equine metritis (CEM) organism. None of 50 single samples from horses thought to be unexposed to the CEM organism was positive to the test, although five showed inconclusive reactions. Samples were examined from 41 mares either proved to be infected or from an infected stud. Of these 21 were positive, 11 were inconclusive and nine were negative. The relationship of the CFT to reactions in the other tests used in this con...
Some serological reactions to “brucella” antigen in the horse. Seventy-three samples of serum, from 69 horses and one zebra, were subjected to the Rose Bengal Plate, serum tube agglutination, complement fixation, and anti-equine globulin (Coombs') tests for brucellosis. Fifty-one of the samples, from 48 horses, were submitted by practising veterinary surgeons; of these, 22 samples were associated with clinical conditions which might have been due to brucellosis. Fourteen samples were from healthy horses known to have been in contact with infected cattle, and six were from horses which were known not to have been exposed to brucellosis. More reactions at a...
A serologic survey of pronghorns in Alberta and Saskatchewan, 1970-1972. To determine the exposure of free-ranging pronghorns (Antilocapra americana Ord) to selected pathogens, serum samples were obtained from 33 live-trapped animals from southwestern Saskatchewan in 1970, and from 26 and 51 animals from southeastern Alberta, in 1971 and 1972, respectively. Antibodies were found to the agents of parainfluenza 3, bovine virus diarrhea, eastern and western encephalomyelitis, infectious bovine rhinotracheitis and the chlamydial group. No serologic reactors were found to the agents of bluetongue, epizootic hemorrhagic disease, brucellosis, or leptospirosis (4 serotypes...
Brucellosis in the horse. Brucella abortus infection in horses is important not only as a clinical entity but also as a potential source of infection for man and other animals. A review of the current knowledge of this disease in the horses is therefore thought to be useful. The incidence of infection in horses has been the subject of many surveys. Most authors used the serum agglutination test as an indication of infection. The majority of surveys were carried out in about 1930 and these showed a wide range in the proportion of positive reactors from 0.5 to 40 percent. Several factors would account for this: variation...
Two cases of suspected Brucella abortus abortion in mares. Extract
Recent reviews of brucellosis in horses (Stableforth and Galloway, Citation1959; Mascaro and Hoffman, Citation1963: Ritscher, Citation1963) refer to Brucella abortus associated with fistulous withers, arthritis and debility and emphasize the rarity of abortion caused by this organism. One case of abortion in a mare caused by Br. abortus was reported as having occurred in Iowa, U.S.A. (McNutt and Murray, Citation1924).
