Indicators and Bacterial Diversity of Subclinical Mastitis in Iran's Industrial Cattle Farms. [PDF]

Vet Med Sci
In this study, the relationship between milk lactose and somatic cell count and the prevalence of bacterial agents of subclinical mastitis was investigated. Klebsiella spp. was identified as the most common pathogen and showed a pattern of antibiotic resistance.

Correlation between Milk Bacteriology, Cytology and Mammary Tissue Histology in Cows: Cure from the Pathogen or Recovery from the Inflammation

Pathogens, 2020
The aim of the current study was to verify the existence of a significant correlation between bacterial isolation (or not) and mammary gland inflammation, using traditional bacterial culturing and PCR, milk leucocytes distributions, and tissue histology.

Severity of experimental escherichia-coli mastitis in ketonemic and nonketonemic dairy-cows. [PDF]

, 1993
The severity of experimental Escherichia coli mastitis in relation to in vitro chemotaxis of polymorphonuclear leukocytes was investigated in cows during negative energy balance. The negative energy balance was induced by feed restriction.
