An investigation was carried out cross-sectional to determine the prevalence of commonly occurring bovine mastitis pathogens at Addis Ababa Ethiopia. Samples were mainly drowned from dairy caws that become clinically ill during clinical observation, which comes for ambulatory service to the Addis Ababa Sholla Veterinary Laboratory. A total of 102 isolates were studied from bacterial culture obtained from the bovine milk samples collected at the clinic in the period from December, 2011 to April, 2012. The most common microbial isolates were Streptococcus species (16.7%), Staphylococcus species (53.9%), Escherichia coli (18.6%)/ Klebsiella species (3.9%) and mixed infection (6.9%). There was a significant association (p>0.05) between quarter level prevalence with the occurrence of pathogenic microorganism, which is isolated from mastitis milk.. The associations of body condition with pathogens were significant (p 0.05%) with the association of animal body condition, all animals (poor, good and moderate) were equally exposed and harbored the disease. The bacterial isolates were S. aureus, coagulase negative staphylococci ,( S. intermidius, S.hyicus), E.coli, Klebsiela and streptococcus species. S, aureus was the predominant isolate accounting for 45.1% followed by E. coli (18.6%) and streptococcus species (16.7%). There was a significant association of lactation period with streptococcal infection (p<0.05). Milk is one of the main components of the diet of the rural society as well as urban and pre-urban area of the study area. It is consumed in the raw state by community. The presence and consumption of such milk may constitute a public health hazard in addition to the reduced milk quality due to mastitis in cow. Ethiopia has an extensive livestock resource, which not kept pace with the increase in human population, constitutes a valuable economic role for the nation. the rates of increase of which are 1.4 % and 2.9% However due to various reasons the country does not respectively. In Ethiopia, based on a study conducted by benefit from this enormous wealth in terms of production Ibrahim (2) from 1975 to 1987, the annual growth rate of such as milk, meat etc. Although inclusion of milk in the total output of fresh cow milk is negligible. Hence, diet is often not commonly available to the public. meeting the milk requirements of the growing human This may be due to the low amount of milk and inadequate population is great concern (1). milk preservation. Only 20% of the milk produced from The factors which limit milk production include animals for human consumption occurs in tropical region, disease, marketing, husbandry and genetics. Among the even though these parts of the world have 74% of the disease mastitis contributes directly to the low milk human population and 65% of the bovine population (1). production. Mastitis, an inflammation of the mammary The World Bank in 1993 has estimated the demand gland is a complex disease that generally involves for milk and dairy products in sub-Saharan Africa will interplay between management practices and having increase by 5.5 million tons in the year 2025, an annual different causes, different degree of intensity and The expansion of milk output in sub-Saharan Africa has
