El Staphylococcus aureus es uno de los principales microorganismos causantes mastitis subclínica en las vacas lecheras. Determinar la prevalencia del S. se hace necesario hatos lecheros grandes y pequeños ubicados región norte, centro sur departamento Valle Cauca, Colombia. Se utilizó metodología National Mastitis Council recolectando 1070 muestras leche 273 17 mediante un muestreo polietápico,...

The objectives of this experiment were to determine interrelationships among mastitis indicators and evaluate the subclinical mastitis detection ability of infrared thermography (IRT) in comparison with the California Mastitis Test (CMT). Somatic cell count (SCC), CMT, and udder skin surface temperature (USST) data were compiled from 62 Brown Swiss dairy cows (days in milk=117+/-51, milk yield=...

In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first experiment, this was deposited into the duct of teats with orf (Group A, n=5) or papilloma (Group B, n=3). In the second, teats were chapped and then, the organism was deposite...

In healthy milk the somatic cell count (SCC) is less than 100.000 cells per mL, although in presence of infectious agents, especially pathogenic bacteria, SCC can be extremely high. Cytological appearance inflammation mammary gland depends on origin and time-course inflammatory response. According to predominant type there suppurative, pyogranulomatous, granulomatous lymphocytic inflammation. P...

El objetivo de este trabajo fue estimar la incidencia mastitis clínica (MC) en tambos e identificar factores individuales asociados a nuevos episodios. Nueve del tipo semipastoril que aplicaban medidas control y prevención mastitis, fueron incluidos visitados dos veces con un intervalo 15 días. Una muestra aleatoria vacas seleccionada primera visita monitoreada durante los días posteriores para...

In Uganda, informal raw milk sales dominate for domestic dairy consumption. This study was implemented to identify the structure of value chain starting from farms that participated in Japan International Cooperation Agency Safe Milk Promotion Mbarara project conducted between 2016 and 2019, assess hygiene conditions along chain, thereby bottleneck intervention. A longitudinal 30 District compa...

Background and Aim: Mastitis in dairy cattle is associated with a high rate of morbidity death, which has major implications for milk production quality. This study aimed to investigate the protein component activity matrix metalloproteinase-2 (MMP-2) -9 (MMP-9) raw samples different testing scores determined using California mastitis test (CMT). Materials Methods: Thirty cows were employed stu...

A total of 120 quarter milk samples from 30 clinically healthy dromedary camel from Al-Jouf, Saudi Arabia were cultured to detect subclinical udder infection. The milk samples were screened by somatic cell count (SCC) and California mastitis test (CMT). Gram-positive cocci were the dominant recovered udder pathogen. The mean value of SCC was 125,000 cells/ mm. Infected quarter had generally hig...

Bovine mastitis is an economically important and highly prevalent infectious disease in dairy herds worldwide. Staphylococcus aureus a common microorganism causing mastitis. A cross-sectional study was conducted between December 2018 September 2019 Shinshicho town, Kembata Tembaro Zone, Southern Ethiopia, to estimate the prevalence, assess associated risk factors antimicrobial susceptibility pr...
