“…In fact, our finding corroborate with earlier reports of 54.4 to 73.3% [11, 14, 15]. Likewise, the preponderance of sub-clinical mastitis and its serious economic relevance compared to clinical mastitis was underscored elsewhere [8, 25, 27, 33, 34]. According to Seegers et al [1], the sub-clinical form is 15 to 40 times more prevalent than the clinical form, and usually precedes the clinical form and is of long duration and high economic relevance.…”

“…The present finding is within the range of cow-level mastitis prevalence (23.2–81.1%) recorded by most recent published studies in the country [10–16]. Some of the earlier findings and our observation is higher relative to the available reports from other African countries whose dairy management is more or less similar to ours, i.e., 51.6% in Tanzania [24], 42.9% in Egypt [27], 38.89% in Sudan [28], 21.1% in Zimbabwe [25], and 51.8% in Rewanda [29]. In contrast, substantially higher prevalence was reported from Uganda (87.9%) [30] and Nigeria (85.3%) [31].…”

“…Evidence on the trend of prevalence increment at the early stage was also produced in previous studies [14, 16, 27, 29]. Perhaps this could be linked to the fact that diapedesis of neutrophils into the mammary gland take longer time in recently calved cows [4], and increased oxidative stress and reduced antioxidant defense mechanisms during early lactation [37].…”

BackgroundMastitis is a disease of major economic importance in dairy industry worldwide. It is of particular concern in developing countries like Ethiopia, where milk and milk products are scarce. The objectives of the study were to estimate the prevalence of mastitis, identify the cow-and herd-level potential risk factors and isolate Staphylococcus aureus, one of etiological agents for contagious mastitis, from cows positive for mastitis. A total of 529 lactating cows selected randomly from 95 herds were screened by California mastitis test (CMT) for sub-clinical mastitis. Also 172 milk samples collected from CMT positive cows were cultured for isolation of S. aureus.ResultsBased on CMT result and clinical examination, the prevalence of mastitis at herd-level was 74.7% (95% CI: 64.5, 82.8). The corresponding cow-level prevalence was 62.6% (95% CI: 58.3, 66.7), of which 59.2 and 3.4% were sub-clinical and clinical mastitis cases, respectively. S. aureus was isolated from 51.2% of the milk samples cultured and 73.2% of the herds affected with mastitis. In the multivariable logistic regression model, the herd-level factors significantly associated (p < 0.05) with the presence of mastitis were herd size, bedding material, and milking mastitic cows last, while at cow-level, breed, parity, stage of lactation, udder and leg hygiene, and teat end shape were noted to have a significant effect on mastitis occurrence.ConclusionThe very high prevalence of mastitis, more importantly the sub-clinical one, in the herds examined revealed the huge potential economic loss the sector suffers. Perhaps this was attributed to lack of implementation of the routine mastitis prevention and control practices by all of the herd owners. The findings of this study warrants the need for strategic approach including dairy extension that focus on enhancing dairy farmers’ awareness and practice of hygienic milking, regular screening for sub-clinical mastitis, dry cow therapy and culling of chronically infected cows.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-016-0905-3) contains supplementary material, which is available to authorized users.

“…Mastitis in dairy cows is a serious problem as it is an economically devastating disease causing immense Table- economic losses in dairy cows and bio health hazard to human worldwide especially in developing countries as in Egypt [31,32]. The present study showed clearly that uses of clinical inspection and CMT examination were provided efficient diagnostic tool for detection and differential of clinical and subclinical mastitis and apparently normal health cattle and this observation is in agreement with Gianneechini et al [33].…”

Evaluation of antibacterial effect of some Sinai medicinal plant extracts on bacteria isolated from bovine mastitis, Veterinary World, 7(11): 991-998. AbstractAim: Bovine mastitis is the most economically important disease affecting dairy cattle worldwide from an economic, diagnostic and public-health point of view. The present study aimed to isolate and identify of bacteria causes mastitis in dairy cows and to evaluate the antibacterial activities of some selected medicinal plants extracts comparing antibiotics used in the treatment of mastitis in Egypt. Materials and Methods:A total of 203 milk samples of dairy cows were collected during the period from February to June 2013 at different Governorates in Egypt. The use clinical inspection and California mastitis test examination were provided efficient diagnostic tool for detection of clinical, subclinical mastitis and apparently normal health cattle. The collected milk samples were cultured on Nutrient, Blood agar, Mannitol salt, Edward's and MacConkey agar plates supporting the growth of various types of bacteria for their biochemical studies and isolation. The antimicrobial activity of plants extracts (Jasonia montana and Artemisia herb alba)with different solvent (ethanol, petroleum ether, chloroform and acetone)were studied in vitro against isolated bacteria from mastitis by paper desk diffusion and minimum inhibitory concentration method (MIC). Results:The prevalence of clinical, subclinical mastitis and normal healthy animals were 34.50%, 24.7% and 40.8% respectively. The major pathogens isolated from collected milk samples were Escherichia coli The MIC values for the extracts ranged from 0.01 to 1.56 mg/ml. when comparing antibacterial activity of A. herb alba plant extracted with acetone solvent on the same bacteria with zone of inhibition values ± SD, ranging from 00±00 to 5.6±0.60 mm. Both extracts from J. montana and A. herb alba plant extracts with petroleum ether, methanol and chloroform solvent were less antibacterial activities than acetone solvent extract. Conclusion:The present study spot highlight on isolation and identification of mastitis pathogens that are fundamental aspects of milk quality, udder health control programs and public health and food safety issues associated with food borne pathogens. J. montana and A. herb alba plants have antibacterial effects more than antibiotics used in the treatment of mastitis. Finally, the medicinal plant extracts can be used to discover bioactive natural product in the form of antibacterial that may be serve the development of new pharmaceutical products. But still need further research necessary to identify active compounds and research to mechanism and drug interaction.

“…astitis is one of the most important diseases in dairy cows throughout the world, and is responsible for significant economic losses to the dairy industry due to loss in milk production, discarded abnormal milk, degrading milk quality and price due to high bacterial or somatic cell count, high treatment cost, increased labor costs, increased risk of subsequent mastitis, herd replacement and problems related to antibiotics residues in milk and its products (Seegers et al 2003 (E.coli ) which are present in the environment (bedding, flooring, droppings) and generally transmitted in any time of cow's life: during milking, between milking and during the dry period, especially at first calving in heifers (Radostits et al, 2000). Elbably et al, (2013) stated that the most prevalent causes of mastitis are S. aureus (25.8%) followed by E.coli (18.7 %) and Streptococcus agalactiae (11.8 %) in addition, Rafik et al, (2014) found that the most prevalent pathogens were E. coli M BENHA VETERINARY MEDICAL JOURNAL, VOL. 29, NO.…”

A B S T R A C TThe objective of the present work is to prepare and evaluate the effectiveness of a locally prepared polyvalent vaccine against mastitis from the most common causes of mastitis. Staphylococcus aureus, Streptococcus agalactiae and Escherichia coli were the most prevalent bacteria recovered from clinical and subclinical mastitis. Montanide ISA-206 adjuvanted inactivated polyvalent vaccine containing the three strains was prepared. Twenty pregnant cows were inoculated intramuscularly with the prepared polyvalent vaccine two months prior to calving and boostering at day 21 from the primary injection. Serum samples from vaccinated and non-vaccinated cows were collected at the 1 st , 3 rd , 8 th , 12 th , 16 th , 20 th and 24 th weeks post vaccination and evaluated immunologically using ELISA. The results showed that immune response was significantly higher in the vaccinated group than that of controls. These results could be indicated the safety and effectiveness of the vaccine in reduction of incidence and severity of clinical cases of mastitis but further studies should be done to elucidate the possibility of field application and effectively.
