Indicators and Bacterial Diversity of Subclinical Mastitis in Iran's Industrial Cattle Farms

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
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.

Invited review: Selective use of antimicrobials in dairy cattle at drying-off

Journal of Dairy Science, 2022
: Administering intramammary antimicrobials to all mammary quarters of dairy cows at drying-off [i.e., blanket dry cow therapy (BDCT)] has been a mainstay of mastitis prevention and control.

Impact of intramammary antimicrobial dry treatment and teat sanitation on somatic cell count and intramammary infection in dairy ewes

, 2011
Mastitis of small dairy ruminants is usually subclinical, and coagulase negative staphylococci have been reported as the most commonly isolated pathogens.

Controlling Mastitis in Cows: Development of an Evaluation Methodology for Determining the Coverage Efficacy of Nozzle Configurations of an Automatic Teat Spraying System

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
In this study, a novel methodology is proposed to assess the homogeneity of the coverage at the outer teat surface and determine the coverage efficacy of nozzle configurations. The methodology developed involves a geometry‐based modelling structure, an image processing‐based evaluation system and a grid algorithm‐based assessment model.

Survey of Genotype Diversity, Virulence, and Antimicrobial Resistance Genes in Mastitis-Causing Streptococcus uberis in Dairy Herds Using Whole-Genome Sequencing

Pathogens, 2023
Streptococcus uberis is one of the primary causative agents of mastitis, a clinically and economically significant disease that affects dairy cattle worldwide. In this study, we analyzed 140 S. uberis strains isolated from mastitis milk samples collected

Practical implications of the World Health Organization Reporting System for Lymph Node, Spleen, and Thymus Cytopathology: Categories and ancillary testing for subtyping of hematolymphoid tumors on FNA biopsy cytopathology using a pattern‐based approach

Cancer Cytopathology, Volume 134, Issue 1, January 2026.
Abstract The objective of the recently published World Health Organization Reporting System for Lymph Node, Spleen, and Thymus Cytopathology (WHO system) is to standardize the diagnostic approach to fine‐needle aspiration biopsies of hematolymphoid tissues.

Assessment of the Herd Management Effects on Mastitis Frequency in Austrian Dairy Farms

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT Mastitis, an inflammation of mammary tissue caused by infection, physical injury, or chemical irritation, is one of the most economically significant diseases in the global dairy industry. Both acute and chronic forms of mastitis lead to an increase in somatic cell counts (SCCs) in milk and a significantly reduced milk yield.

Serum Amyloid A and Lactoferrin Concentrations in Milk at Mastitis Diagnosis Can Serve as a Predictive Indicators of Intramammary Status 7 Days Later

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT This study investigated whether the inflammatory component levels in bovine milk measured on the day of mastitis diagnosis were associated with recovery outcomes 7 days later. Milk was collected on Day 0 (the initial day of mastitis diagnosis) and Day 7 from 40 quarters of 32 dairy cows diagnosed with spontaneous acute mastitis.

Serratia Species Isolated from Bovine Intramammary Infections

Journal of Dairy Science, 1991
Intramammary infections from which Serratia spp. were isolated were studied over a 32-mo period in a research dairy herd consisting of approximately 120 lactating cows. A total of 29 Serratia spp. intramammary infections were detected and accounted for 9% of all Gram-negative bacterial intramammary infections.
