“…Mastitis is an inflammation of the parenchyma of mammary gland that causes physical and chemical changes in milk and leads to pathological condition of the glandular tissue (Ranjan et al, 2011). The majority cases of mastitis are caused by bacteria (Radostits et al, 2007).…”

A cross-sectional study was conducted from November 2013 to April 2014 to isolate coagulase positive Staphylococcus (CPS) from subclinical mastitic (SCM) lactating cows, to establishing prevalence, to identify risk factors and to determine the antimicrobial susceptibility pattern of CPS isolates in and around Haramaya University, Eastern Ethiopia. A semi-structured questionnaire survey, California mastitis test (CMT) , bacterial isolation and identification and in vitro antimicrobial susceptibility tests were conducted during the study. A total of 210 dairy cattle from seven farms were screened for SCM by CMT. The prevalence of SCM in the study areas was 71.4% (150/210) . Milk samples were collected from 562 quarters of 150 cows free of clinical mastitis but positive in CMT. Among these cows 38 of them had blind quarters (6. 76%). The prevalence of CPS was found to be 66.0% (99/150) and 28.46% (160/562) on animal and quarter basis, respectively. Among the risk factors studied, SCM due to CPS was significantly higher (P > 0.05) in older cows (100%) than younger (70.0%), in cows during late lactation (96.3%), in cows which gave more than 5 births (100%), in cross-breed cows (71.2%) than local breed cows (54.3%), in cows with udder I teat injuries (96.3%) and in cows managed under poor house hygiene (82.5%). Antimicrobial susceptibility testing of 9 antibiotics carried out using Kirby-Bauer disc diffusion method and revealed high multidrug resistance of 71 (87.6 %). High level of resistance to common drugs like ampicillin (90.1 %), penicillin (67.9%), and tetracycline (54.3%) was registered. In contrast, the CPS isolates were susceptibility for chloramphenicol, gentamycin and kanamycin at 63%, 46.9%, and 41.97%, respectively. In conclusion, the study confirms the importance of CPS as a mastitis causing multidrug resistant bacterium. Therefore, improved management and early treatment of SCM cases with drug of choice is imperative to tackle CPS mastitis.

“…Increase in temperature-humidity index (THI) increases occurrence of clinical mastitis (Morse et al, 1988) while no trend was evident with average rainfall. Hot weather condition especially above 24 °C has also been linked to increased milk SCC, increased microbes, reduced dry matter intake and low immunity leading to negative energy balance which makes dairy cattle more susceptible to infections (Singh et al, 1996;Olde et al, 2007;Ranjan et al, 2011). Precipitation also poses a series of problems and ingestion of pathogens resulting in environmental mastitis (Bramley, 1982;Hogan and Smith, 2003).…”

Season. Temperature humidity index. PALABRAS CLAVE ADICIONALESEstación. Índice de temperatura-humedad. SUMMARYThe study was conducted to find out the effect of different seasons on incidence of mastitis throughout the year in Indigenous cows, crossbred cows and Murrah buffaloes. Lactation records pertaining to the 12 year period were collected and incidence of mastitis was plotted against the climograph of the Karnal zone, Haryana, India. The hot humid climate was found to adversely affect the incidence of mastitis in all the breeds of cows and Murrah buffaloes. The incidence was significantly affected by the season (p<0.01) in all the breeds, however incidence was lowest in Murrah buffaloes in comparison to cows. Further incidence was more in Sahiwal and Tharparkar cows (p<0.01) than the crossbred Karan Swiss and Karan Fries cows. The increase in temperature humidity index resulted in increased incidence of mastitis in cows (p<0.01) but Murrah buffaloes were less affected. RESUMENEste estudio fue realizado para hallar la influencia estacional sobre la incidencia de la mastitis a lo largo del año, en vacas indígenas, vacas cruzadas y búfalas Murrah. Se analizaron los registros de lactación correspondientes a un periodo de 12 años, la incidencia de mastitis fue comparada con los climogramas de la zona de Karnal, Haryana, India. El clima cálido y húmedo afectó negativamente a la incidencia de mastitis en todas las razas bovinas y los búfalos. La incidencia fue afectada significativamente por la estación (p<0,01) en todas las razas, aunque el efecto fue menor en las búfalas Murrah. El registro de mastitis fue más elevado en las razas Sahiwal y Tharparkar (p<0,01) que en los cruces Karan-Suiza y KaranFries. El incremento del índice de temperatura y humedad dio lugar a una mayor incidencia de mastitis en las vacas (p<0,01), aunque las búfalas Murrah resultaron menos afectadas.

“…Bacterial propagation as well as the load of pathogens increases as heat and humidity increases in the environment [84]. On the contrary, another study has reported a greater occurrence of coliform mastitis during the cold months when the temperature was recorded to be less than 21°C [85,86] in the environment.…”

Mastitis is one of the most costly devastating diseases in the dairy industry. Bovine mastitis can be classified as clinical or subclinical based on clinical features of the disease. Subclinical mastitis occurrence is more prominent compared to clinical form and its prevalence is more than 20 to 50% of cows in given herds. Both forms cause substantial financial losses due to reduced milk yield, degraded milk quality, drug costs and veterinary expenses, early culling of cows and increased labour costs for the farmers. The chief causal organisms of mastitis are cell-walled bacteria, even though mycoplasma, algae and yeast have also been identified to cause mastitis. Numerous influencing factors like physiological, pathological, environmental or genetic factors may contribute to the occurrence of mastitis in dairy cattle. Presently, different types of antibiotics are prescribed for the treatment of mastitis. However, therapeutic success rate of mastitis is generally poor because of pathological changes in the udder parenchyma, mastitogenic bacterial and related factors, indiscriminate use of antibiotics and poor animal husbandry practices. These evidences focus the necessity for discovering completely newer strategies for treatment of mastitis. This review will highlight the key etiological agents and factors affecting the manifestation of mastitis, and the recent advancement of therapeutic strategies including application of antibiotic-based therapies by doing antibiotic sensitivity test as a prospective approach to prevent and control mastitis in dairy herds.
