“…are found the cause of subclinical mastitis. The prevalence of P. haemolityica (4.35%) in the present study is comparable with those reported by Mengistu et al [7], Gadir et al [29], and Semereab and Molla, [30] 3.2%, 2.1%, and 5.4%, respectively, but higher than Woubit et al [27] [31] which proved their potentiality to cause mastitis. The species of Aeromonas, Neisseria, and Acinobacter have been also isolated with a low prevalence.…”

“…The study animals were lactating camels which are in various parities (1-10) and lactation stages (l-7 months). Therefore, their lactation stage were grouped in to three categories; 1-3, 4-6, and >6 months as early, mid, and late stage of lactation, respectively, while their parity was categorized as one, two, and >3 births [ 7 ].…”

“…The causative agents of camel mastitis are not well defined and studied [ 4 ]. However, few available literatures indicate that the major bacterial pathogens isolated from subclinical mastitis were Staphylococcus , E. coli , Corynebacterium , Streptococcus , Bacillus , and Micrococcus species [ 6 , 7 ]. Moreover, according to Abdurahman [ 8 ] report, subclinical mastitis is not usually treated in traditionally managed camels and will often take a natural course to chronicity resulting in permanent loss of milk production.…”

Objective. A crosssectional study was conducted between September 2015 and August 2016 in the district of Afar Regional State, Northeastern Ethiopia, to characterize the most prevalent bacterial pathogens and identify the associated risk factors of camel subclinical mastitis. California mastitis test (CMT) was used as a screening test, and standard bacteriological methods were carried out for isolation and identification of the pathogens. Results. Among the total 96 lactating camels examined, 25 were found positive with the overall prevalence of 26%, with 25% and 1% subclinical and clinical mastitis cases, respectively. Totally, 384 quarters of udder were examined; of these, 10 of them were blind while the rest 374 were nonblind teats. The quarter level prevalence of subclinical mastitis was 8.9%. The analysis showed that statistically significant difference ( P < 0.05 ) of tick infestation and subclinical mastitis. Additionally, among the bacteriologically tested 34 CMT positive milk samples, all of them showed growth on nutrient and blood agar plate. Out of these culture isolates, the major bacterial pathogens identified were Staphylococcus aureus (8.7%), Staphylococcus hyicus (6.52%), Staphylococcus intermedius (6.52), Coagulase-negative staphylococci (19.57%), Bacillus (19.57%), Escherichia coli (6.52%), and Pasteurella multocida (6.52%) species. Therefore, appropriate control measures and awareness creation to the community should be practiced.

“…However, in most of them the main objective was usually to analyze the presence of different pathogens (among them, S. aureus ), and to count CFU (Colony Forming Units) in order to determine the rate of contamination of the tested food [ 63 , 64 , 65 , 66 , 67 , 68 ]. In other studies, milk samples of sick animals were analyzed with the objective of detecting the presence of S. aureus as the mastitis-causing agent [ 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 ]. There were also a few papers in which the presence of S. aureus and/or MRSA was studied in food products from healthy animals.…”

The interest about Staphylococcus aureus (S. aureus) and methicillin resistant S. aureus (MRSA) in livestock, and domestic and wild animals has significantly increased. The spread of different clonal complexes related to livestock animals, mainly CC398, and the recent description of the new mecC gene, make it necessary to know more about the epidemiology and population structure of this microorganism all over the world. Nowadays, there are several descriptions about the presence of S. aureus and/or MRSA in different animal species (dogs, sheep, donkeys, bats, pigs, and monkeys), and in food of animal origin in African countries. In this continent, there is a high diversity of ethnicities, cultures or religions, as well as a high number of wild animal species and close contact between humans and animals, which can have a relevant impact in the epidemiology of this microorganism. This review shows that some clonal lineages associated with humans (CC1, CC15, CC72, CC80, CC101, and CC152) and animals (CC398, CC130 and CC133) are present in this continent in animal isolates, although the mecC gene has not been detected yet. However, available studies are limited to a few countries, very often with incomplete information, and many more studies are necessary to cover a larger number of African countries.

As of other dairy animals, dromedary camel could be affected by mastitis, a complex disease occurring worldwide among dairy animals, with heavy economic losses largely due to clinical and subclinical mastitis. Yet, little is known about the occurrence and potential risk factors exposing to lactating camel mastitis in Ethiopia. Consequently, a cross-sectional study was carried out from November 2018 to April 2019 so as to determine the prevalence, associated risk factors, and major bacterial pathogens causing mastitis in traditionally managed lactating camels in Gomole district of Borena Zone. Consequently, 348 lactating camels were examined for clinical and subclinical mastitis, using California Mastitis Test (CMT). The overall prevalence of mastitis was 22.4% (78/348), including clinical 4.3% (15/348) and subclinical 18.1% (63/348) cases, respectively, whereas the quarter level prevalence of mastitis was 16.6% (232/1,392). Of the total 1,392 examined teats, the right hind (RHQ) (4.3%, 60/1392) and left hind quarters (LHQ) (4.3%, 60/1392) were the most frequently infected quarter, whereas the left front quarter (LFQ) (3.9%, 55/1392) was the least infected quarter. Age, body condition score, and lactation stages were significantly associated ( p < 0.05 ) with lactating camel mastitis prevalence among the putative risk factors. Among 312 quarters milk samples subjected to bacteriological examination, 69.9% (218/312) yielded mastitis causing pathogens, both Gram-positive and -negative bacterial isolates, while no growth was observed in 30.1% (94/312) of quarters sampled. Of the bacterial isolates obtained by culturing, Streptococcus spp. excluding Streptococcus agalactiae (S. agalactiae) (26.1%; 57/218) and Coagulase negative Staphylococci (22.9%, 50/218) were the dominant isolates identified, whereas S. agalactiae (3.2%, 7/218) was the least isolates obtained. The prevalence of camel mastitis in the study area was found to be considerably high. Hence, implementation of integrated approaches has great importance in the study setting for the prevention and control of mastitis so as to improve quality of camel milk, minimize economic loss, and prevent significant public health risks.
