Two unidentified mycoplasmas, N3 and N11, isolated from the respiratory tract of horses, were found to cross-react with strains of M. mycoides subsp. mycoides in indirect immunofluorescence tests, growth-inhibition tests carried out by the running drop/agar-well method, and in complement-fixation and double immunodiffusion tests. Serologically, the equine mycoplasmas were not completely identical with any of the reference strains of M. mycoides with which they were compared. Their cultural characteristics, ability to digest coagulated serum and casein, and survival at 45 degrees C, however, suggested that they were more closely related to strains of M. mycoides subsp. mycoides, such as Y-goat, which are found in goats, than to strains of that subspecies which are pathogenic for cattle.

Plant diseases cost the global economy billions of US dollars every year. The problem has mainly been addressed by using chemical pesticides, but recently, the use of ants has shown promising effects against plant pathogens. However, the mechanisms accounting for these effects have not yet been determined.

ZnAlO and CuAlO spinel nanoparticles were prepared by a modified Pechini method and used with the natural chitosan (CS) and shellac (SH) polymers to form novel composite membranes as promising food packaging materials. The selection of ZnAlO and CuAlOspinel nanoparticles was based on their antibacterial characteristics, availability, and economy. Using a straightforward and adaptable solution mixing and casting method, the bio-composites were created.

Article Synopsis
- The study analyzed food products and food poisoning cases for toxin-producing bacteria using PCR, revealing a new toxin profile in 0.4% of isolates.
- It classified toxin profiles into groups A-J, finding that 91.8% of isolates had certain toxin genes and varying prevalence of other specific toxins.
- Whole-genome sequencing identified four species and three novel sequence types, while all isolates showed antibiotic resistance, particularly for beta-lactam, indicating significant genetic diversity and resistance in the context of Polish food products.
Arsenic Stress Mitigation Using a Novel Plant Growth-Promoting Bacterial Strain Bacillus mycoides NR5 in Spinach Plant (Spinacia oleracea L.).

Present study aimed to identify arsenic (As)-resistant bacterial strains that can be used to mitigate arsenic stress. A bacterium Bacillus mycoides NR5 having As tolerance limit of 1100 mg L was isolated from Nag River, Maharashtra, India. It was also equipped with plant growth-promoting (PGP) attributes like phosphate solubilization, siderophores, ammonia, and nitrate reduction, with added antibiotic tolerance.
