Mastitis is one of the most economically important diseases in dairy farms worldwide. It is particularly important in Ethiopia where no routine prevention and control practices are in place. This cross-sectional study was carried out between October 2017 and June 2018 to estimate the prevalence of mastitis, identify the associated risk factors and isolate bacterial causes in dairy farms located in southern Ethiopia using standard microbiological methods and questionnaire survey. A total of 686 lactating cows which were found in 122 selected dairy farms were investigated by physical examination and California mastitis test. The overall cow-level prevalence of mastitis was 54.2% (95% CI: 50.5 – 57.9%). Based on the study site, the prevalence was 55.7% in Hawassa, 54.3% in Arsi Negele, 52.6% each in Wondo Genet and Wolayta Soddo towns with no significant (p > 0.05) difference among the sites. The majority of mastitis cases were subclinical (48.1%) while the clinical mastitis was only 6.1%. Of the 122 herds tested, 109 (89.3%; 95% CI: 82.1 – 93.9%) had at least a cow positive for mastitis. The study showed that high parity number (OR = 1.6; p = 0.015), flat (OR = 4.5; p <0.001) and round (OR = 2; p <0.001) teat end shape, history of mastitis in preceding lactation (OR = 3.3; p <0.001), and slightly (OR = 3.5; p < 0.001), moderately (OR = 4.9; p < 0.001), and very dirty (OR = 9.2; p < 0.001) udder and legs were the major risk factors which are significantly associated with higher prevalence of mastitis. Based on the available media and reagents, the major bacteria isolated from subclinical mastitic milk samples were Staphylococcus spp. (57.3%), Streptococcus spp. (18.6%), E. coli (17.3%) and Bacillus spp. (7.5%) in order of their abundance. The present study revealed a high prevalence of mastitis, particularly the subclinical one, and the associated risk factors. Enhancing the awareness of dairy farmers, regular screening of cows for subclinical mastitis, proper treatment of the clinical cases, improving the hygienic condition of the cows, and culling of chronically infected cows are critically important to prevent and control bovine mastitis.

Ethiopia is located in tropical region and livestock production represents a major national resource and forms an integral part of the Agricultural production system and livelihood of the society. Dairy farming being one of the agricultural production in Ethiopia, is practiced mainly as an extensive type of management system, which involves smallholder farmers in rural areas and semi-intensive and intensive managements in per urban and urban areas. Despite a large number of milking cows, there is low milk production because of many factors, including low genetic potential of indigenous breeds, extensive and poor husbandry practices, and widespread livestock diseases. Among the dairy cows’ diseases, mastitis is prevalent in the dairy production system incurring high economic losses and social burden. Several reports on mastitis in Ethiopia are present but are scattered. We focused on reviewing articles published in indexed journals reporting bovine mastitis to summarize its common etiologies, prevalence, and risk factors in Ethiopia. The common pathogens reported from different parts of Ethiopia are Staphylococcus aureus (Staph. aureus), non-aureus staphylococci, Streptococcus spp. (Strep. agalactiae, Strep. dysgalactiae, Strep. uberis), coliforms (E. coli, Klebsiella pneumonae), Trueperella pyogenes and Mannheimia haemolytica (M. haemolytica), Pseudomonas aeruginosa (P. aeroginosa), Enterobater aerogenes, Bacillus species, Micrococcus species. Staphylococcus aureus and E. coli are the most common isolates from clinical mastitis (CM). Staphylococcus aureus is also the most frequently isolated pathogen from sub-clinical mastitis (SCM). Sub-clinical mastitis which usually ranges from 25.4% to 73.3%, is highly prevalent than the clinical cases of mastitis which ranges from 3.2% to 26.5%. Several mastitis risk factors were reported. These were breed of animals, parity number, stage of lactation, presence of teat/udder lesion and hygiene measure of the farms. Thus, it is essential to plan and implement control measures including maintenance of good dairy farm environment, udder and milking hygiene at farm level; regular monitoring of udder health with special attention to exotic, crossbred and lactating cows and culling of older cows. Isolation, characterization and conducting antibacterial sensitivity test should be integral part of mastitis control strategy for effective control of the mastitis causing pathogens.

A cross sectional study was conducted in selected districts of East Shewa Zone of Oromia Regional Stat from November 2013 to April 2014 on dairy cows to determine the prevalence of mastitis and determinant of its major risk factors. The study was done on 250 lactating cows, of which 109 were local and 14 1 cross breed by using clinical examination , California mastitis test (CMT) and culture. Of these 108 (43.2 %) were positive by clinical examination and CMT for clinical and sub clinical mastitis, with prevalence of 4 % and 38.8 %, respectively. All the p otential risk factors considered in this study namely, parity ( p < 0.05), breed (p< 0.05), age (p < 0.05), stage of lactation (p < 0.05),breed (p < 0.05) and husbandry (p < 0.05) showed a significant effect on prevalence of mastitis in present study. Thus , high prevalencence of mastitis was observed in older cows >7 years and cows with parity >7 but high prevalence was obtained on early and late stage of lactation. The study also revealed that cross breed lactating cows and those managed intensively were s usceptible to mastitis. The highly prevalent bacteria isolated were Staphylococcus aurous (46 %) followed by Streptococcus agalactiae which accounts (19.4 %), and others were Staphylococcus intermidius, E. coli and Corynebacterial species with respective pr oportion of 16.6, 10.9 and 7.1%. The present study also revealed that mastitis is the major problem in smallholder dairy farms in the study area specially the sub clinical form, so that creation of awareness about the importance and prevention of subclinic al mastitis among smallholder dairy farmers, milking infected animals and periodic monitoring of infection status of the udder is recommended.

A cross-sectional study was undertaken to determine the prevalence of bovine mastitis, and to assess potential risk factors among lactating cows, both local and crossbreeds, in and around Eltarf town in northeast Algeria. A total of 324 lactating cows were included in the survey, examined for mastitis by clinical examination of the udder and teats and tested using the California Mastitis Test (CMT) to determine clinical and subclinical mastitis. Data was collected in a questionnaire during the farm visit. The overall prevalence was 41.66% (135/324), of which 9.80% (32/324) were clinical and 31.79% (103/324) subclinical cases. Out of 1296 quarters examined, the prevalence rate was 41.04% (532/1296), where 9.25% (120/1296) were clinical and 31.79% (412/1296) subclinical aspects of mastitis. Right Hind teats (RH) showed the highest rate of inflammation (51.54%), followed by the Left Hind (LH) teat in second place (44.44%), Right front quarter (RF; 36.11%) and lastly Left Front (LF; 32.09%). The relationships of risk factors with mastitis status were determined using Chi-square analysis, associations between mastitis and the independent variables, including parity and hygienic condition of the udder, teat and housing of cows were statistically significant (P&lt;0.05) in the univariate analysis. Mastitis prevalence was significantly higher in cows having delivered four calves (87.50%) comparing to cows with less than four calves (28.16%), irrespective of lactation stage. Significantly higher mastitis prevalence was also observed in poor hygienic conditions (38.82%; P&lt;0.05) than good hygienic condition (22.07%). Other risk factors such as breed, age, lactation stage, rearing system, housing system and tick control infestation did not differ significantly (P&gt;0.05). This study indicated that mastitis is a prevalent disease and a serious problem across herds in and around the Eltarf district in Algeria. Further detailed epidemiological, microbiological, and economic analysis studies are required at the national level to tailor existing control and prevention strategies. Regular surveillance measures are recommended.
