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 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.

“…About 57.1% of cases with reproductive disorders were due to metritis and endometritis (Ali et al, 2010). The most common uterine bacterial isolates in dromedaries are Campylobacter spp., Brucella spp., Coxiella burnetii, Salmonella spp., Chlamydia spp., Escherichia coli, Pseudomonas and Staphylococcus aureus (Al-Afaleq et al, 2012;Mshelia1 et al, 2014;Khalafalla et al, 2017;El-Deeb et al, 2019). Owing to the diversity of these pathogens, a single antibiotic program might not be sufficient due to the bacterial resistance and the broad range of bacterial species.…”

Lactobacillus spp. is one of the beneficial lactic acid producing microbiota in the vagina, which is important for a healthy vaginal environment. However, little is known about vaginal Lactobacillus in dromedary camels (Camelus dromedarius). Therefore, this study aimed to isolate vaginal lactic acid bacteria (LAB) in dromedary camels and to study the probiotic potential of selected isolates. A total of 75 vaginal swabs were collected from pluriparous, non-pregnant, non-lactating dromedary camels. The LAB were isolated using deMan, Rogosa and Sharpe broth and agar media. Suspected LAB isolates were subjected to catalase testing and Gram staining and examined for indole production, nitrate reduction, hemolytic activity, cell surface hydrophobicity, auto- and coaggregation, antibacterial activity and characterized by 16S rRNA amplification and sequencing. Eighteen LABs were isolated from the 75 vaginal swabs. Among the 18 LAB isolates, six were Lactobacillus plantarum, eight were Lactobacillus fermentum, and four were Lactobacillus rhamnosus. None of the LAB isolates was hemolytic and only four LAB were H2O2 producing. The percentage of hydrophobicity ranged from 0% to 49.6%, 0% to 44.3% and 0% to 41.6% for hexadecane, xylene and toluene, respectively. All isolates showed higher (P < 0.05) autoaggregation after 24 h of incubation compared to 4 h. Furthermore, all LAB showed higher coaggregation (P < 0.05) and antimicrobial activity toward Staphylococcus aureus than to Escherichia coli. All LAB isolates were vancomycin resistant and sensitive to streptomycin, erythromycin, kanamycin and chloramphenicol. Only, three LAB isolates were resistant to tetracycline. The dromedary camel vaginal LAB isolates exhibited varying degrees of in vitro probiotic properties tested in this study and showed promising activity against the most common bacterial causes of endometritis in dromedary camels. Further investigation of the in vivo effect of these isolates is warranted.
