During the period between February, 2004 and December, 2006, a cross-sectional study was performed to investigate some epidemiological aspects related to camel brucellosis in Jordan. Four hundred twelve camel sera from 37 herds were randomly collected and analyzed using Rose Bengal plate test and complement fixation test. A structured pre-tested questionnaire was administered to collect information on camel herd health and management. A multivariable logistic regression model was constructed to investigate risk factors associated with seropositivity to Brucella antigens. Moreover, the incidence of Brucella-specific abortion was investigated in 7 camel herds located in different locations in Southern Jordan. The true prevalence of Brucella-seropositive in camels was 12.1%. Thirteen (35.1%) herds had at least one positive camel. The seroprevalence ofbrucellosis in camels was significantly higher in the southern part of Jordan than that in central or northern Jordan. The multivariable logistic regression model on both individual and herd levels revealed large herds and contact with small ruminants as risk factors for Brucella seropositivity. On the other hand, using disinfectants was identified as a protective factor (OR = 0.8; 95% CI: 0.1, 0.9) only on the camel herd level. The incidence of Brucella-caused abortion was 1.9%. Brucella melitensis biotype 3 was isolated from 4 aborted camel fetuses.

Results of this study indicate that the biochemical profile of does with subclinical pregnancy toxemia had significantly lower glucose (P < .001) and total protein (P = .048)concentrations, whereas urea concentrations were significantly higher (P = .042) compared with pregnant control does [corrected].

Isolates of Trichophyton and Microsporum species are common important animal pathogens capable of causing dermatophytosis. In this report, isolation and identification of fungi causing ringworm in cattle and horses in Jordan were undertaken. Ten dairy farms and two large maintenance stables of horses located in different parts of Jordan with a history of cutaneous lesions were chosen for the present study. A complete clinical examination of 375 calves and 316 horses was performed. Skin samples were taken by scraping from 57 calves and 28 horses. Each sample was subjected to direct microscopic examination and cultured on mycobiotic agar (DIFCO) at 28 °C for 2-6 weeks. Affected calves were treated by a locally prepared ointment containing salicylic acid, benzoic acid, sulfur and iodine in 100 g vaseline. Recovery rate following treatment was monitored.Results revealed that 30.6% and 18% of infected calves and horses had clinical lesions of ringworm, respectively. Most of the lesions observed on the affected calves were alopecia and/or circumscribed grayish-white, crusty, raised lesions. These lesions commonly affected the head, neck, dewlap, and chest area. Trichophyton species and Microsporum species were the most commonly isolated fungi, with a prevalence rate of 69.01% and 8.46%, respectively. All treated calves responded to topical treatment within one month. In horses, lesions were seen as round patches of 3-5 cm in diameter as raised hair and soreness spreading on the axillary girth, trunk and over the rump. Microsporum equinum and T. equinum were the most frequent fungi isolated with an incidence of 40% and 24%, respectively.
