Understanding distribution of bovine mastitis pathogen spp. can contribute to the treatment decision and the control within programs of bovine mastitis, we conducted a meta-analysis to investigate the epidemiology and antimicrobial resistance rates of spp. associated with bovine mastitis in China. Three databases, namely, PubMed, Google scholar, and China National Knowledge Infrastructure database, were utilized to obtain relevant publications. According to PRISMA reporting standards, a total of 38 publications were included in the research, among them, 7 papers included an AMR test. The pooled prevalence of spp. was 5.41% (95% CI: 3.87-7.50%). Subgroup analysis revealed that the prevalence was higher in South China (8.55%, 95% CI: 3.57-19.09%) than in North China (4.22%, 95% CI: 2.46-7.14%), in 2010-2020 (7.45%, 95% CI: 5.29-110.40%) than in 2000-2010 (3.14%, 95% CI: 1.90-15.14%), and in the clinical bovine mastitis cases (7.49%, 95% CI: 3.71-14.54%) than in the subclinical cases (4.03%, 95% CI: 1.55-10.08%). The pooled AMR rate revealed that spp. were most resistant to sulfonamides (45.07%, 95% CI: 27.72-63.71%), followed by tetracyclines (36.18%, 95% CI: 23.36-51.34%), aminoglycosides (27.47%, 95% CI: 17.16-40.92%), β-lactams (27.35%, 95% CI: 16.90-41.05%), amphenicol (26.82%, 95% CI: 14.17-44.87%), lincosamides (21.24%, 95% CI: 7.65-46.75%), macrolides (20.98%, 95% CI: 7.20-47.58%), polypeptides (15.51%, 95% CI: 6.46-32.78%), and quinolones (7.8%, 95% CI: 3.25-17.56%). The climate difference between South and North China and the natural pathogenicity of spp. may be the primary reasons for its distribution, and the prevalence of spp. indicated that the genus is an increasing hazard to the dairy industry. The prevalence of AMR in China is commonly higher than in the European countries and Canada, this is a very important concern for strategy programs to control bovine mastitis caused by spp. in China.

Recent years have seen advances in clinical biochemistry of domestic animals which have highlighted comparative differences between species and have also identified fundamental aspects of the biochemical mechanisms in physiological conditions and disease, that have implications across species, including human, health and welfare. From investigations in diverse species using biochemical, immunological, proteomic and metabolomic approaches a series of species particularities and unexpected results for some biomarkers have been made. These observations cover (1) the differences between species in the acute phase protein (APP) response to infection and inflammation; (2) the non-hepatic synthesis and release in the mammary gland, adipose tissue and intestine of APP (3) the response of haptoglobin (HP) as a biomarker for stress; (4) observations in non-mammalian species related to hemopexin and HP; (5) the response of bile acids in milk to mastitis; (6) barley serine protease inhibitors being identified in bovine faeces; (7) alkaline phosphatase being present in bovine nasal secretion; (8) saliva findings with analytes such as adenine deaminase showing different activity between saliva and serum and a detergent-like surfactant protein, latherin being found in equine saliva and sweat and (9) serum enzymes and selective muscle protein reaction of Atlantic salmon as an example of the differences in biochemistry between terrestrial and aquatic species.

Introduction: are commonly found in intramammary infections associated with bovine subclinical mastitis in dairy cattle, yet their genomic diversity and antimicrobial resistance dynamics remain poorly characterized, particularly in African settings.
Methods: This study presents a comparative genomic analysis of 17 isolates from South Africa, including five newly sequenced bovine mastitis strains and twelve porcine-derived genomes retrieved from GenBank. analysis using multilocus sequence typing (MLST), virulence genes, antibiotic resistance genes and plasmids replicon types were used to characterise these isolates.

Escherichia coli, an opportunistic pathogen, induces acute bovine mastitis, leading to severe milk yield reduction, dairy product discard, and substantial economic losses. This not only jeopardizes cow health and farm profitability but also raises food safety concerns, highlighting the need for effective treatments. Lycopene (LYC), a natural carotenoid with potent anti-inflammatory and antioxidant properties, has shown potential in mitigating inflammatory diseases.

Background: This study addresses the global challenge of subclinical bovine mastitis (SCBM) in dairy cows, a prevalent disease causing substantial economic losses, by investigating the mechanistic basis of , a traditional herbal remedy with empirically validated efficacy but incompletely understood modes of action.
Methods: Initially, the active components of were identified using LC-MS/MS. Dose-response trials were conducted in Holstein cows ( = 24 SCBM cases; = 6 healthy controls), along with multi-omics integration, including 16S rRNA sequencing for rumen/feces microbiota and UHPLC-MS metabolomics for serum analysis.

In order to explore the therapeutic effect of natural compound Pulsatilla saponin B4 (PSB4) on clinical mastitis (CM) in dairy cows, 40 dairy cows with CM and 20 healthy dairy cows were selected as experimental samples in a large dairy farm. The CM cows were randomly divided into two groups (20 cows in each group), namely the PSB4 group treated with PSB4 neck intramuscular injection and the positive drug (PC) group treated with ceftiofur sodium neck intramuscular injection as a positive control. Another 20 healthy dairy cows were neck intramuscular injected with the same amount of normal saline to serve as a normal control (NC) group.
