A preclinical study of seven batches of lactoglobulin, a new biological preparation against opportunistic bacteria and salmonellae, has been carried out. High antibacterial activity of the preparation with respect to the virulent forms of Salmonella typhimurium, Salmonella enteritidis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, Proteus mirabilis has been established. The preparation has been shown to be safe and nontoxic. The 4-year term of its storage at a temperature of 6 degrees +/- 4 degrees C has been substantiated.

is a common opportunistic pathogen that causes gastrointestinal diseases in livestock and poultry. Our preliminary research has demonstrated that administering oral yeast-cell microcapsule (YCM)-mediated DNA vaccines can effectively stimulate mucosal immunity, thereby preventing the occurrence of gastrointestinal diseases. In this study, the α-toxin gene was first cloned and the H126G and C-terminal (C247-370) mutations were created.

Opportunistic pathogens, such as Aeromonas hydrophila, can cause damage to freshwater crayfish (Astacus leptodactylous) in some situations. In addition to direct damage to the body, microplastics (MPs) can also be responsible for transmitting pathogens to the animal. Accordingly, this research was prepared to investigate the effects of MP on the damage caused by A.

Background: Opportunistic fungal infections like oral candidiasis account for a significant amount of morbidity in HIV disease and an indicator of immune suppression. Fluconazole is a broad-spectrum antifungal agent that has been extensively used in the management of oral, candidiasis. Highly efficacious fluconazole is also known to have systemic toxicity due to high drug interaction and hence the present study focuses on the formulation of bioadhesive film as a controlled release carrier for fluconazole.
