A Novel Marine Mammal Coxiella burnetii—Genome Sequencing Identifies a New Genotype with Potential Virulence

, 2023
The obligate intracellular bacterial pathogen Coxiella burnetii has been identified in a few species of marine mammals, some of which are showing population declines. It has been hypothesized that C. burnetii in marine mammals is a distinct genotype that

Coxiella burnetii inhibits host cell death by ubiquitination‐induced inactivation of an apoptosis nuclease

mLife, Volume 5, Issue 4, Page 432-446, August 2026.
Abstract Coxiella burnetii modulates a variety of host cell processes to create a niche permissive for its intracellular replication using effectors injected by its Dot/Icm type IV secretion system. More than 130 such effectors have been identified, but the function of most of them remains unknown.

Cow Milk Risk Factors Associated With Bacterial Contaminations Along Dairy Value Chain in Lushoto and Handeni Districts, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Milk and milk products are important sources of nutrients to human and animals, but due to its physicochemical characteristics and nutritional value, it serves as an excellent medium for growth of microorganisms. Most of smallholder dairy farmers have no training on livestock husbandry and milk handling practices.
