“…Other factors that could be associated with S. agalactiae mastitis in camels include udder/teat lesions such as camel pox [13,25]; increased age and parity of the camel [6,12]; and late stage of lactation [25,26]. The isolation of coccobacillus from sampled camels with mastitis was unexpected and requires further investigation.…”

“…This argument is founded on our observation and the fact that most of the respondents in this study neither washed the milking containers nor their hands in between milking camels and where they did, the quality of water was questionable. Other factors that could be associated with S. agalactiae mastitis in camels include udder/teat lesions such as camel pox [ 13 , 25 ]; increased age and parity of the camel [ 6 , 12 ]; and late stage of lactation [ 25 , 26 ]. The isolation of coccobacillus from sampled camels with mastitis was unexpected and requires further investigation.…”

“…Mastitis is among the most important diseases of camels and has a worldwide distribution [5]. The disease can be either clinical or subclinical [6][7][8] and is associated with significant economic losses. These losses are attributed to the cost of treatment, reduced milk production, compromised quality of milk and public health concerns due to the widespread use of antimicrobials [9][10][11].…”

“…Past studies have shown that udder infections in lactating camels are widespread. In Africa, mastitis in camels has been reported in Egypt [ 6 , 14 ]; Somalia [ 8 ]; Ethiopia [ 7 , 15 ]; and Kenya [ 5 , 16 , 17 ]. The reported prevalence of camel mastitis under pastoralism in Kenya ranges from 46 to 93.3% [ 5 , 16 , 17 ].…”

Background and Aim: The one-humped camels (Camelus dromedarius) adapt very well to arid and semi-arid (ASALs) environments and continue to thrive and produce milk even during severe droughts when cattle, sheep, and goats experience high mortalities. These attributes make the dromedaries very vital for the survival of pastoralists, especially in the ASALs of Africa. Mastitis is among the most important diseases of camels and can cause significant economic losses, thereby endangering the livelihoods of pastoralists. This study aimed to estimate the prevalence, risk factors, and antimicrobial sensitivity of mastitis-causing pathogens in lactating camels in Isiolo County, Kenya. Materials and Methods: This was a cross-sectional study conducted in July and August 2021. A questionnaire was administered to the camel keepers to capture data on herd-level factors. Lactating camels were then examined for any visible signs of clinical mastitis and as well as to capture data on other animal-level factors such as age, weight, and body condition score. A composite milk sample was collected aseptically from randomly selected camels in a herd. The samples were initially tested for somatic cell counts (SCC) using Somatos mini® automatic cell counter. Culture and sensitivity testing was then carried out on any milk sample that had SCC ≥ 200,000 cells/mL. The descriptive analysis was initially used to summarize the continuous and categorical farm and camel factors, while mixed regression models were used to explore the association between/across mastitis and the farm as well as camel-level factors. Results: A total of 210 lactating camels from 23 herds were selected and sampled in this study. The average age of camel keepers was 48.3 ± 16.3 years and they were involved in rearing camels for a mean of about 14.3 ± 8.6 years. The total number of camels in a herd ranged from 10 to 287, with the mean total herd milk production being 34.5 ± 24.9 L/day. The mean daily milk production per camel was 2.8 ± 1.7 L while the range for days in milk was between 21 and 787 days. The average age of camel first calving and the inter-calving interval was 56.3 ± 9.9 and 27.7 ± 9.9 months, respectively. The median parity of the dam was three and the body condition score was two. About 39.7% (83/210) of the sampled camels had clinical mastitis during the current lactation. The overall prevalence of mastitis (SCC ≥ 200,000 cells/mL) in camels was 17.6%. The main pathogens isolated were Streptococcus and Staphylococcus bacteria. Streptococcus isolates were mainly sensitive to ampicillin and resistant to cefaclor. All 18 Staphylococcus isolates were sensitive to tetracycline, while 12/18 isolates were resistant to ampicillin. The factors that were significantly associated with mastitis were the age of the respondent (p = 0.038), the number of years involved in camel rearing (p = 0.024), presence of clinical mastitis since calving (p = 0.039), body condition score (p = 0.040), and age of the dam at the time of examination (p = 0.072). Conclusion: Results from this study revealed that mastitis is an important condition among camels in the pastoral communities of Isiolo County, Kenya. Thus, pastoralists should continue to be aware of and trained on mastitis occurrence and its control in the pastoral ecosystem to reduce potential economic losses.
