Rickettsia rickettsii (Rickettsiales: Rickettsiaceae) Infecting Amblyomma sculptum (Acari: Ixodidae) Ticks and Capybaras in a Brazilian Spotted Fever-Endemic Area of Brazil

Journal of Medical Entomology, 2019
Abstract The bacterium Rickettsia rickettsii is the agent of Brazilian spotted fever (BSF), a highly fatal disease that is transmitted in Brazil mainly by the tick Amblyomma sculptum Berlese, which uses capybaras (Hydrochoerus hydrochaeris Linnaeus) as major hosts.

First detection of endosymbiotic bacteria in biting midges Culicoides pulicaris and Culicoides punctatus , important Palaearctic vectors of bluetongue virus

, 2014
Heritable bacteria have been highlighted as important components of vector biology, acting as required symbionts with an anabolic role, altering competence for disease transmission, and affecting patterns of gene flow by altering cross compatibility.

Human granulocytic ehrlichiosis in pancreas transplant recipients

, 2001
Human ehrlichioses are tick-borne infections caused by bacteria in the genus Ehrlichia of the family Rickettsiaceae. To date there have been three cases of ehrlichiosis reported in the transplant population, a human monocytic ehrlichiosis (HME) infection

Expanding the β‐Lactamase Family in the Human Microbiome

Advanced Science, Volume 11, Issue 46, December 11, 2024.
β‐lactam resistance is mainly driven by β‐lactamases. The study analyzes 1369 characterized and 16 204 putative β‐lactamases, identifying nine from eight clusters. The highest gut β‐lactamase abundance is found in Japan and the lowest in Fiji. β‐lactamase levels correlate with β‐lactam use and income, increasing in colorectal cancer and cardiovascular ...

Wolbachia in Antarctic terrestrial invertebrates: Absent or undiscovered?

Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.
Endosymbiotic bacteria Wolbachia are recognized for their role in influencing host survival and stress resistance, particularly in cold environmental conditions across various species. However, our analysis of available data reveals a notable absence of Wolbachia in species abundant in the extreme cold conditions of Antarctica.

Diversity of bartonellae in mites (Acari: Mesostigmata: Macronyssidae and Spinturnicidae) of boreal forest bats: Association of host specificity of mites and habitat selection of hosts with vector potential

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 518-529, December 2024.
Bats play a major role in the circulation of zoonotic pathogens. Mites (Macronyssidae and Spinturnicidae) may facilitate the long‐term maintenance (and even local recurrence) of Bartonella‐infestations. Mites may transmit several distinct Bartonella strains, which cluster phylogenetically close to Bartonella species known for their zoonotic role ...

Responses of vascular plant fine roots and associated microbial communities to whole‐ecosystem warming and elevated CO2 in northern peatlands

New Phytologist, Volume 242, Issue 3, Page 1333-1347, May 2024.
Summary Warming and elevated CO2 (eCO2) are expected to facilitate vascular plant encroachment in peatlands. The rhizosphere, where microbial activity is fueled by root turnover and exudates, plays a crucial role in biogeochemical cycling, and will likely at least partially dictate the response of the belowground carbon cycle to climate changes.
