Comparison of Virulence Patterns Between Streptococcus uberis Causing Transient and Persistent Intramammary Infection [PDF]

Frontiers in Veterinary Science, 2022
The objectives of this study were determined by two experiments including Experiment 1 (EXP1) using Streptococcus uberis obtained from a weekly longitudinal study to compare virulence patterns between transient and persistent intramammary infection (IMI),

New Insights into the Significance of PARP-1 Activation: Flow Cytometric Detection of Poly(ADP-Ribose) as a Marker of Bovine Intramammary Infection [PDF]

Cells, 2021
Bovine intramammary infections are common diseases affecting dairy cattle worldwide and represent a major focus of veterinary research due to financial losses and food safety concerns.

Risk factors for postcalving intramammary infection with Mycoplasma species in first-lactation cows on a conventional dairy farm: A retrospective case control study [PDF]

JDS Communications
Mycoplasma spp. are highly contagious bacteria that cause chronic, subclinical infections in dairy cattle and are intrinsically resistant to many antimicrobials.

Trace Element Changes in Goat Milk Following Experimentally Induced Intramammary Infection With Biofilm Positive and Negative Strains of Staphylococcus aureus. [PDF]

Vet Med Sci
Biofilm‐positive Staphylococcus aureus induced significantly a higher secretion of calcium, selenium, potassium and phosphorus into goat milk than biofilm‐negative strains, suggesting greater mammary epithelial damage and barrier dysfunction, with potential implications for mastitis severity assessment and targeted therapy.

N-Acetyl-β-D-Glucosaminidase Analysis in Sheep Milk Can Detect Early Intramammary Infection with High Yields If Incorporated into Mathematical Algorithms [PDF]

Animals
The aim of this study was to analyse the effect of intramammary infection (IMI) on N-acetyl-β-D-glucosaminidase (NAGase) enzyme values and to study its predictive capacity using different algorithms.

Compartmentalized cytokine networks and systemic immune remodelling in bovine mammary H5N1 infection [PDF]

Emerging Microbes and Infections
Highly pathogenic avian influenza A H5N1 has recently expanded its mammalian host range; in 2024, genotype B3.13 emerged in U.S. dairy cattle with pronounced mammary tropism.

Transcriptome-derived variants in milk reveal host response signatures to subclinical intramammary infection in Holstein cattle [PDF]

Journal of Animal Science and Biotechnology
Background Beyond conventional transcriptome profiling, RNA-sequencing (RNA-Seq) enables the discovery of variants within expressed genes linked to complex traits such as mastitis resistance or susceptibility. In this study, RNA-Seq was performed on milk

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

Veterinary 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.

Dairy cows infected with influenza A(H5N1) reveals low infectious dose and transmission barriers [PDF]

Nature Communications
Highly pathogenic avian influenza A(H5N1) virus exhibits a strong tropism for the bovine mammary gland, challenging our understanding of influenza A virus host range and tissue specificity.

Infective mastitis due to bovine‐associated Streptococcus dysgalactiae contributes to clinical persistent presentation in a murine mastitis model

Veterinary Medicine and Science, 2021
Background Mastitis caused by Streptococcus dysgalactiae (GCS) is a major pathology of dairy cows. The mechanisms by which GCS intramammary infection is established and maintained involve not only bacterial adherence and invasion but also modulation of ...
