Exploring the diversity of Rickettsia in carnivores of the Brazilian cerrado: An analysis of the relationship with ticks

Ticks and Tick-Borne Diseases
The proximity of wildlife reserve areas to anthropized regions facilitates the spread and exchange of infectious agents, including pathogens with zoonotic potential, thereby increasing health-related risks for species already threatened with extinction ...

Ticks and tick‐borne pathogens in selected abattoirs and a slaughter slab in Kumasi, Ghana

Veterinary Medicine and Science, Volume 10, Issue 5, September 2024.
•Amblyomma variegatum was the predominant tick species. •Zoonotic pathogens R. africae, R. aeschlimannii, C. burnetii and CCHFV were identified. •Abattoir workers are at risk of zoonotic infections. Abstract Background Ticks are vectors of pathogens that affect the health of animals and humans. With the constant trade of livestock across borders, there

Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Tools and mechanisms of vacuolar escape leading to host egress in Legionella pneumophila infection: Emphasis on bacterial phospholipases

Molecular Microbiology, Volume 121, Issue 3, Page 368-384, March 2024.
Scheme of how secreted exit‐associated phospholipases are engaged by Legionella pneumophila during lytic escape. 1. L. pneumophila enters the host cell in an endocytic manner. 2. The bacterium actively establishes an intracellular niche (Legionella‐containing vacuole, LCV) which is required for replication.

Genotyping of the Tick-Borne Pathogen Rickettsia parkeri

, 2023
Rickettsia parkeri is a pathogen of interest to public health as the causative agent of R. parkeri rickettsiosis. Amblyomma maculatum, a vector of R. parkeri, is currently undergoing a range expansion out of its historic range along the Gulf Coast of the United States, including northwards into Southeastern Virginia.

Rickettsial infection in ticks infesting wild birds from two eco-regions of Argentina

Revista Brasileira de Parasitologia Veterinária
Several tick-borne Rickettsia species are recognized human pathogens in Argentina. Here we evaluated rickettsial infection in ticks collected on passerine birds during 2011-2012 in two eco-regions of Argentina.
