Background Reproduction is a basic prerequisite to efficient livestock production. The reproductive performance depends upon the normal structure and functions of genital organs. Methods A cross-sectional study design was conducted from November 2016 to May 2017 to identify and compare the frequency of reproductive organ pathological lesions and to isolates bacteria associated with uterine lesions in female dromedary camels and cows slaughtered at Addis Ababa and Adama municipal abattoirs and Akaki slaughter house. Purposive sampling technique was used to collect 280 reproductive tracts from cow and female dromedary camel. Following gross inspection tissue samples with lesion were collected for histopathological and bacteriological studies and were done according to standard protocols. Result Various pathological lesions with different degrees of severity were observed in 34.2% (n = 48) and 36.4% (n = 51) of dromedary camel and cow, respectively. Age, species and body conditions of animals were not statistically associated with most of disorders (P > 0.05). The lesions encountered in dromedary camels were 21.4%, 7.14%, 1.42%, 2.85% and 1.42% uterine, ovarian, oviductal, vaginal and cervical lesions, respectively. However, 16.4%, 14.2%, 3.57%, 1.42% and 1.42%, ovarian, uterine, oviductal, vaginal and cervical lesions were seen in examined cows, respectively. The result showed that the collected uterine tissue was positive for single and/or mixed bacterial infection. Bacterial isolated includes, Staphylococcus species 28.5%, Streptococci species 19.6%, Coynebacterium species 8.9%, Escherichia coli 26.78%, Salmonella species 10.7% and Klebsiella species 5.35% were isolated from cows uteri, while in the dromedary camels, Escherichia coli 35.5%, Staphylococcus species 26.6%, Streptococcus species 13.3%, Pseudomonas species 6.6%, Proteus species 4.4%, Salmonella species 8.8% and Klebsiella species 4.4%.were isolated. Histopathologically, endometrial glands degeneration, sloughing of epithelium, peri-glandular cuffing and infiltrations of inflammatory cell were some of characteristic changes observed in uterus. Conclusions Reproductive organ pathological lesions found to be an important problem in female dromedary camel and cow and it was observed that the bacteria isolated from camel’s uteri were similar to those in cows. The role of each reproductive lesions incriminated as causes of reproductive failures in this livestock species needs further investigation.

Background Reproduction is a basic prerequisite to efficient livestock production. Reproductive performance depends on the normal structure and function of genital organs. A cross-sectional study was conducted from November 2016 to May 2017 to identify and compare the frequency of reproductive tract pathological lesions and to isolate bacteria associated to uterine lesions in female dromedary camels and cows slaughtered at Akaki camel slaughterhouse and Addis Ababa and Adama municipal abattoirs. Purposive sampling technique was employed to include and examine the reproductive tracts of all slaughtered animals (280; 140 cows and 140 camels) during the study period. Result The study examined a total of 280 (140 cows and 140 camels) reproductive tracts. Various pathological lesions with different degrees of severity were observed in 48 (34.2%) and 51 (36.4%) of dromedary camels and cows, respectively. In dromedary camels, the most prevalent lesion was uterine lesions (21.4%) followed by ovarian lesions (7.14%); while in cows, ovarian lesions were the most prevalent (16.4%) followed by uterine lesions (14.2%). In general, 56 bacteria were isolated from cows’ uterine lesion, the Staphylococcus species (28.5%), Streptococci species (19.6%), Coynebacterium species (8.9%), Escherichia coli (26.78%), Salmonella species (10.7%) and Klebsiella species (5.35%) being the most representative isolates. In camels, however, 45 bacteria were isolated from uterine lesions with higher prevalence of Escherichia coli (35.5%), Staphylococcus species (26.6%), Streptococcus species (13.3%), Pseudomonas species (6.6%), Proteus species (4.4%), Salmonella species (8.8%) and Klebsiella species (4.4%). Bacteriological data showed that the major isolates were similar, although slightly more frequent in occurrence in cows. Microscopically, uterine inflammatory lesions evidenced endometrial glands degeneration, epithelium sloughing, peri-glandular cuffing, and inflammatory cells infiltration. Conclusions In female dromedary camels and cows, pathological lesions of the reproductive tract showed great prevalence, with similarity in bacterial isolates in both species. The role of each reproductive lesion and bacterial isolates as causal agents of reproductive failures in these livestock species, however, needs further investigation.

A cross sectional study was conducted from October 2017 to April 2018 in Damot Woyde District of Wolayta Zone to estimate the prevalence of mange mite infestation in cattle and identify the associated risk factors. Out of 375 animals examined, 41 (10.9%) were found positive for mange mite infestations. No statistically significant difference was noted among sex, age, breed and management categories (p>0.05); however, the prevalence differences noted between animals with different body condition score were statistically significant (p<0.05). The highest prevalence was recorded in animals with poor body conditions (27.71%), followed by those with medium (9.97%) and good body conditions (0.83%). Four mite genera were found in the area namely; Sarcoptes 19 (46.3%), Psoroptes 5 (12.2%), Demodex 13 (31.7%) and Chorioptes 4 (9.8%). Mange was frequently recovered from dewlap, followed by neck, tail head, face, brisket and leg. The overall prevalence (10.9%) shows that mange is an important disease that needs attention in the area. Therefore, farmers need to be made aware on the strategic use of acaricides following veterinary recommendation. Moreover, there is a need for regular research on the sensitivity of the parasites to the drugs in use.
