Prevalence of Brucella spp. in milk from aborted and non-aborted animals in Dhamar governorate, Yemen

Abstract
Brucella infection in animals is considered\r\na significant problem in most countries of\r\nthe world. Our study designed to determine\r\nthe prevalence of brucella in field animals\r\nmilk in Dhamar governorate, Yemen. Total\r\nof 808 raw milk samples from non-aborted\r\nfield animals, 120 milk samples from aborted\r\nanimals, and 30 pasteurized milk samples\r\nwere tested by Milk-Ring Test (MRT),\r\nmilk-ELISA test, isolation, and identification\r\nof Brucella species, and antibiotic susceptibility.\r\nThe prevalence of brucella in\r\nmilk samples from field animals were 0.8%,\r\n2.6%, and 2% in cows, sheep, and goat milk\r\nsamples respectively with MRT, and 0.8%,\r\n1.3% and 1.6% in cows, sheep, and goat\r\nmilk samples respectively with the milk-\r\nELISA test. The prevalence rate in milk\r\nsamples from aborted animals were 33%,\r\n64% and 41.2% with the MRT and 39%,\r\n49%, and 41.2% in cows, sheep, and goats\r\nrespectively with the milk-ELISA test. All\r\npasteurized milk samples were negative for\r\nthe milk-ELISA test. The result of isolation\r\nshowed 0.1% of Brucella in milk samples\r\nfrom field animals while 9.2% from aborted\r\nanimals. All isolates of Brucella species\r\nwere sensitivities to rifampicin, doxycycline,\r\nkanamycin, gentamicin, streptomycin,\r\ntetracycline, ciprofloxacin,\r\nwhile resistant to ampicillin, erythromycin,\r\nand novobiocin. In conclusion, the high\r\nprevalence of milk brucella especially in\r\naborted animals need focusing and build\r\ncontrolling strategies plans to decrease the\r\nlosses to the economy and avoiding transferred\r\nto humans with unpasteurized milk consumption.
