Abstract Botulism is a severe and often fatal disease in equine patients worldwide. Clostridium botulinum is a ubiquitous soil organism which produces a potent neurotoxin resulting in neuromuscular blockade and flaccid paralysis in affected animals. Definitive diagnosis is often impractical or impossible, leading to diagnosis and treatment based on ...

The presence of botulinum neurotoxin-producing Clostridia (BPC) in food sources is a public health concern. In favorable environmental conditions, BPC can produce botulinum neurotoxins (BoNTs) outside or inside the vertebrate host, leading to ...

When overexpressed in Staphylococcus aureus, the type I toxins SprA1 and SprA2 form membrane pores, with SprA1 creating stable pores and SprA2 forming transient ones. Both induce concomitant membrane depolarization, ATP release, and growth arrest, while only SprA1 causes membrane permeabilization due to its stable pore formation.

Using bioinformatic tools, we identified a diverse defensome in Actinobacillus pleuropneumoniae, featuring various defense mechanisms. Genomes show co‐occurring systems like CRISPR, Abi, and restriction‐modification (RM) systems, underscoring the complexity and dynamic nature of their defensome cargo.

Development of an Innovative in Vitro Potency Assay for Anti-Botulinum Antitoxins
Botulinum neurotoxins are bacterial proteins that cause botulism, a life-threatening disease. Therapy relies mostly on post-intoxication antibody treatment. The only accepted method to measure the potency of, and to approve, antitoxin preparations is the

The fitness of Anopheles coluzzii mosquito lines (VK strain) selected for early and late egg hatching was compared with each other and a reference strain (Mopti). There was an observed increase in fitness in fecundity and survival among the late‐hatching lines, but no negative effects of selection on fecundity and adult survival were detected.

The bacterial Type III toxin-antitoxin system, ToxIN, is a dynamic protein-RNA complex with stability-dependent antiviral abortive infection activity. [PDF]
Bacteria have evolved numerous defense systems to protect themselves from viral (bacteriophage) infection. The ToxIN system of Pectobacterium atrosepticum is a Type III toxin-antitoxin complex and "altruistic suicide" anti-phage system, which kills phage-
