Colonization and local host response following intramammary Staphylococcus chromogenes challenge in dry cows

open access: yesVeterinary Research, 2021
Although extensive research has been performed on bovine non-aureus staphylococci (NAS), several aspects such as bacteria-host interaction remain largely unstudied.

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

open access: yesPathogens, 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.

Cow, farm, and management factors during the dry period that determine the rate of clinical mastitis after calving [PDF]

open access: yes, 2007
The purpose of the research was to investigate cow characteristics, farm facilities, and herd management strategies during the dry period to examine their joint influence on the rate of clinical mastitis after calving.

Fecal non-aureus Staphylococci are a potential cause of bovine intramammary infection

open access: yesVeterinary Research, 2020
The presence of non-aureus staphylococci (NAS) in bovine rectal feces has recently been described. Similar to other mastitis causing pathogens, shedding of NAS in the environment could result in intramammary infection.

PATHOLOGICAL AND BACTERIOLOGICAL STUDIES ON MAMMARY GLAND AFFECTIONS IN ONE HUMPED SHE CAMEL 9DROMEDARIESO [PDF]

open access: yesVeterinary Medical Journal - Giza, 1994
Ninety out of three hundred mammary quarters of seventy-five she-camel udders were affected. Eighty-eight out of the ninety were recognized as mastitis (97.8%) and as a pre-cancerous in two 2.2%).

Response to somatic cell count-based selection for mastitis resistance in a divergent selection experiment in sheep [PDF]

open access: yes, 2009
A divergent selection experiment in sheep was implemented to study the consequences of log-transformed somatic cell score (SCS)-based selection on resistance to natural intramammary infections.

open access: yesAssiut Veterinary Medical Journal, 2012
Salmonellaenterica serovar typhimurium (S. typhimurium) was isolated from both dead and clinically diarrhoeic beef calves, which had history of severe diarrhoea.

Coliform mastitis [PDF]

open access: yesVeterinary Research, 2003
Gram-negative bacteria that commonly cause bovine mastitis are classified as environmental pathogens. The point sources of coliform bacteria that cause infections include bedding materials, soil, manure and other organic matter in the environment of cows.

ANTIBIOTIC RESISTANCE PROFILES AND PREVALENCE OF ESBL-PRODUCING ESCHERICHIA COLI AND KLEBSIELLA PNEUMONIAE IN MASTITIS CASES ON DAIRY FARMS IN EGYPT [PDF]

open access: yesAssiut Veterinary Medical Journal
Bovine mastitis, an inflammation in dairy cattle, causes significant economic losses, often triggered by bacterial pathogens like Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae).

Evaluation of minor pathogen intramammary infection, susceptibility parameters, and somatic cell counts on the development of new intramammary infections with major mastitis pathogens [PDF]

open access: yes, 2012
Major mastitis pathogens such as Staphylococcus aureus, Streptococcus uberis, Streptococcus dysgalactiae, and coliforms are usually considered more virulent and damaging to the udder than minor mastitis pathogens such as Corynebacterium spp.
