ABSTRACT
Little is known about the risk factors of human brucellosis in Jordan. A case-control study was conducted involving 56 Jordanians who had been treated for brucellosis and at least 3 matched controls for each case (n = 247). Matching was for sex, age, locality (the same village) and socioeconomic standard. Univariate and multivariate logistic regression analyses were used. In all, 17 risk factors were examined related to: contact with various livestock, milk and milk product consumption, drinking-water treatment and disease awareness. Most variables were associated with brucellosis in the univariate analysis but the final logistic model included only 4: milking sheep and goats (OR 3.5), consumption of raw feta cheese made from sheep and goat milk (OR 2.8) and consumption of cows' milk (OR 0.4) and boiled feta cheese (OR 0.4). Small ruminant farmers need to be trained in safer milking practices and feta cheese making procedures.

Little is known about the risk factors of human brucellosis in Jordan. A case-control study was conducted involving 56 Jordanians who had been treated for brucellosis and at least 3 matched controls for each case [n = 247]. Matching was for sex, age, locality [the same village] and socioeconomic standard. Univariate and multivariate logistic regression analyses were used. In all, 17 risk factors were examined related to: contact with various livestock/ milk and milk product consumption, drinking-water treatment and disease awareness. Most variables were associated with brucellosis in the univariate analysis but the final logistic model included only 4: milking sheep and goats [OR 3.5], consumption of raw feta cheese made from sheep and goat milk [OR 2.8] and consumption of cows' milk [OR 0.4] and boiled feta cheese [OR 0.4]. Small ruminant farmers need to be trained in safer milking practices and feta cheese making procedures

Results differ as to whether Brucella infection during pregnancy increases a woman's risk of miscarriage. We determined the seroprevalence of BrucelIa spp. among a sample of women with miscarriage and women with no history of miscarriage in Jordan during January-July 2003. Serum samples were collected from 445 women with miscarriage and a similar number of women with no history of miscarriage, matched on age, socioeconomic status and residence. Sera were tested using the Rose Bengal plate test and complement fixation test. The true seroprevalence among women with miscarriage was 1.8% (95% CI: 0.6-3.0), while the true seroprevalence among women with no history of miscarriage was 1.0% (95% CI: 0.08-1.9). There was no significant difference between seroprevalences of Brucella spp. among women with miscarriage and those with no history of miscarriage (P= 0.6).
