The viability of Mycoplasma agalactiae and Mycoplasma mycoides subsp. capri (Mmc) was assessed in goat colostrum treated at different temperatures. Samples of colostrum were inoculated with reference strains of M. agalactiae (PG2) and Mmc (PG3) and heated at 56°C or 60°C for 0, 30, 60, 90 or 120 min. Viable colonies of M. agalactiae were recovered after all treatments and there was a significant reduction in the concentration of viable M. agalactiae after 30 min at 56°C and 60°C. No viable colonies of Mmc were observed after 60 min at 60°C.

Background: Control strategies against contagious agalactia (CA), considered one of the most important diseases affecting small ruminants in countries surrounding the Mediterranean, are mainly based on traditional strategies considered suboptimal such as the use of inactivated vaccines and antibiotics. This manuscript analysed the efficacy of an alternative non-mandatory official control programme based on a multi-platform diagnostic panel and biosecurity developed and started in 185 herds placed in a contagious agalactia endemic area of Spain, using the data of 74,080 samples collected and analysed during a 4 years-period (2018-2021).
Results: Globally, the combined analyses of bulk tank milk (BTM), ear or nasal swabs (in goats or sheep, respectively) and the serology to detect Mycoplasma agalactiae (Ma), allowed the detection of 40.

To preliminarily understand the pathogenic mechanism of (Mg) GroEL protein, we used bioinformatics tools to predict the structure and function of Mg GroEL protein and then constructed the recombinant plasmid pET-28a-GroEL. The protein expression was induced by 0.2 mmol/L IPTG, and the expressed protein was purified by Ni-iminodicitic acid (IDA) column affinity.

Article Synopsis
- * MFGs feature a unique structure with a lipid core and a membrane rich in bioactive components that aid in energy release and support immune health in developing gastrointestinal tracts.
- * Research suggests MFGs can be enhanced to address specific nutritional deficiencies while also having potential therapeutic benefits for neurodevelopment and defense against infections.

Background: Mycoplasma hyopharyngis is a commensal bacterium in the upper respiratory tract of swine. As it is recognized to be apathogenic, examinations regarding this species are scarce, compared to other swine mycoplasmas. However, in a few cases, M.
