“…Unlike, the report by [38] who reported uterine lesion occur more commonly in cows 19.4% than dromedary camels 17.4%; the present study indicated that uterine lesions were a frequently observed lesion in dromedary camels 21.4% than cows 14.2%. The variation between studies might be attributed due to the differences in season, management, geographical environment, level of nutrition and health management of animals included in the study.…”

“…Microscopic lesions observed in the present study were those of the in ammatory uterine changes indicated by; endometrial glands degeneration, endometrial epithelial sloughing and hyperplasia of mesothelium cells in few cases, peri-glandular cu ng and in ltrations of in ammatory cells. These ndings were similar to what was observed in earlier reports [41,38,11].…”

“…Staphylococcus species, Streptococcus species Escherichia coli, Salmonella species and Klebsiella species were the most common bacterial isolated from cow's and camels' uterine lesions and accounted for 90.8% and 88.6 % of the total isolates respectively for the two animal species. These nding were similar to the report of [38]. As it is reported by [68] most of the aforementioned bacteria attributed to most of the clinical reproductive disorders.…”

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.

“…In this study the prevalence of uterine lesions was greater in dromedary camels than in cows, even if a previous report showed an opposite trend [27]. The variation between studies might be attributed to the differences in season, management, geographical environment, level of nutrition and health management of animals.…”

Background: Reproduction is a basic prerequisite to efficient livestock production. Reproductive performance depends upon the normal structure and function of genital organs. Methods: A cross-sectional study was conducted from November 2016 to May 2017 to identify and compare the frequency of pathological lesions in the reproductive tract and to isolate bacteria associated to uterine lesions in female dromedary camels and cows slaughtered at Akaki camel slaughter house and Addis Ababa and Adama municipal abattoirs. Purposive sampling technique was used to collect 280 reproductive tracts from cows and female dromedary camels. Following gross inspection at abattoirs, tissue samples with lesion were collected for histopathological and bacteriological investigation. Result: Various pathological lesions with different degrees of severity were observed in 48 (34.2 %) and 51 (36.4%) of dromedary camels and cows, respectively. Uterine lesions were the most prevalent (21.4%) lesions observed in dromedary camels followed by ovarian lesions (7.14%); while in cows, ovarian lesions were the major prevalent (16.4%) lesions followed by uterine lesion (14.2%). The result showed that there were 56 bacteria isolated from cows uterine lesion with 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 prominent isolates; while in camels, there were 45 bacteria isolated with 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%) being the most frequently isolated. The result showed that the major isolates were similar with slightly higher in cows. Histopathologically, endometrial glands degeneration, sloughing of epithelium, peri-glandular cuffing and infiltrations of inflammatory cell were some of characteristic changes observed in uterus. Conclusions: Pathological lesions in reproductive organs in female dromedary camels and cows showed great prevalence, with similarity in bacterial isolates between the two species. The role of each reproductive lesions and bacterial isolates incriminated as causes of reproductive failures in this livestock species needs further investigation.

“…Although considered a less conventional source of meat compared to cattle, sheep and goats (Kurtu, 2004), it can be a better option for animal protein compared to cattle as it has a large body mass and good dressing percentage (Mukasa-Mugerwa, 1981). Camels are adversely affected by lack of water, poor feed, heat stress and diseases (Bamaiyi & Kalu, 2011;Mshelia et al, 2013) leading to decrease in productivity. Studies have shown that camels are susceptible to common diseases affecting other animal species such as brucellosis and bluetongue (Yousif et al, 2003;Amstel & Kennedy, 2010;Wernery, 2012;Gadahi et al, 2013).…”

This study was carried out to determine the seroprevalence of bovine viral diarrhea virus (BVDV) antibodies in camels presented for slaughter at the Maiduguri abattoir using a BVDV specific indirect enzyme-linkedimmunosorbent assay (ELISA). Ninety (90) serum samples collected from adult male and female camels were tested for BVDV antibodies. From the samples tested, 28 (31.1%) were positive for BVDV. The sex distribution of the positive samples showed 7 (33.3%) males and 21 (30.4%) females were positive for BVDV antibodies. The results showed no statistically significant (p<0.05) difference in the sex prevalence of camels observed in the study. This finding demonstrates the presence of BVDV antibodies in camels in Maiduguri. Further studies will be required to elucidate the epidemiology of BVDV infection in camels and other livestock species in the study area.
