title: Udder health problems and major bacterial causes  of camel mastitis in Jijiga, Eastern Ethiopia: implication  for impacting food security.
abstract: One hundred and forty-five traditionally kept lactating camels (Camelus dromederius) were examined for mastitis by combination of clinical, mastitis card test and subsequent bacteriological isolation. Clinical and sub-clinical mastitis were prevalent in 8.3% (95%CI = 4.6, 14.4) and 20.7% (95%CI = 14.6, 28.4) of the studied animals, respectively. This gives an overall mastitis prevalence of 29.0% (95%CI = 21.9, 37.2) at animal and 17.9% (95%CI = 14.9, 21.3) at quarter levels. High proportion (33.8%) of lactating camels had blind teats and 5.5% had lesions on udder or teat. Taking clinical mastitis and blocked teats into account, the study revealed that only 57.9% of the camels have four teats for milk production. Out of the 505 quarter milk samples examined, 80 (15.8 %) quarters were positive for indicator paper. Upon subsequent culturing, 68.8% (55 out of 80) of the quarter milk samples yielded bacteria. Staphylococcus, Streptococcus, E. coli and Bacillus species were the major isolates. Mastitis prevalence was significantly (p<0.05) affected by tick infestations, udder lesions, and increased age and parity of the animals. In conclusion, mastitis is a major problem in traditionally managed camels and deserves further attention owning to its potential impact on milk production affecting food security.
