The escalating challenge of multidrug-resistant bacteria has prompted research into alternative therapeutic strategies, including milk microbiota transfer and phytochemical treatments. This study evaluates milk chemical elements as potential biomarkers during alternative treatments for Staphylococcus warneri-induced goat mastitis. Seven female Parda Alpina goats were studied, with six receiving sequential treatments: milk microbiota transplantation (MMT) from the seventh goat (donor), two days later, intra-mammary 7-epiclusianone administration followed. The right udder of the six goats received the treatments and different time points while the left udder served as the control. Milk samples (n = 120) were analyzed using X-ray Energy Dispersive Spectroscopy (XEDS) to monitor trace and macro elements. Milk elemental level variations were observed across both treatments. Notable changes included increased iron levels from MMT initiation, reduced copper and zinc levels during MMT, and decreased sodium levels following 7-epiclusianone treatment. These results suggest zinc, copper, iron, and sodium could serve as potential biomarkers for monitoring mastitis treatment effectiveness. Additional research with broader and more diverse sample populations would help validate these findings and explore the method's broader applicability.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 3","pages":"166"},"PeriodicalIF":1.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144039079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A co-infection involving the rabies virus, Bartonella koehlerae, and Leishmania infantum was identified in a Black Myotis bat collected from a household in São Manuel, a city endemic for visceral leishmaniasis.

To the best of our knowledge, this is the first report of a bat co-infected with rabies virus, B. koehlerae, and L. infantum. The co-infection of three important pathogens in a Black Myotis highlights the multifaceted role of neotropical bats as reservoirs of zoonotic agents.

In this study, the intestinal porcine epithelial cell line-J2 (IPEC-J2) was employed as an in vitro model to study the intestinal cells injury caused by FB1 and the underlying mechanisms. By measuring IPEC-J2 cell viability, intracellular reactive oxygen species, gene levels, and protein levels, it was found that FB1 dose-dependent induced IPFC-J2 cell injury, oxidative stress, and inflammation. Meanwhile, FB1 significantly increased the expression of necroptosis-related genes and proteins in IPEC-J2 cells, indicating that FB1 induced the occurrence of necroptosis.
