Detección molecular de Rickettsia bellii en garrapatas Ixodes loricatus (Acari: Ixodidae) asociadas a roedores de la provincia de Buenos Aires, Argentina [PDF]
The aim of this study was the detection of Rickettsia in ticks of sigmodontine rodents from Northeastern Buenos Aires province, Argentina. A total of 222 rodents were captured collecting 10 ticks identified as Ixodes loricatus Neumann, which were ...

Effect of environmental variables on the abundance of Amblyomma ticks, potential vectors of Rickettsia parkeri in central Brazil. [PDF]
Amblyomma ticks are vectors of both Rickettsia rickettsii and R. parkeri in the Americas, where capybaras (Hydrochoerus hydrochaeris) are the main hosts in urban areas, thus contributing to the transmission of spotted fever.

Rickettsia bellii infecting Amblyomma sabanerae ticks in El Salvador. [PDF]
Four Amblyomma sabanerae ticks collected from a turtle (Kinosternon sp.) in San Miguel, El Salvador, were found by molecular analysis to be infected by Rickettsia bellii. We provide the first report of Rickettsia bellii in Central America, and the first report of a Rickettsia species in El Salvador.

Development of a Rickettsia bellii-Specific TaqMan Assay Targeting the Citrate Synthase Gene. [PDF]
Rickettsia bellii is a rickettsial species of unknown pathogenicity that infects argasid and ixodid ticks throughout the Americas. Many molecular assays used to detect spotted fever group (SFG) Rickettsia species do not detect R. bellii, so that infection with this bacterium may be concealed in tick populations when assays are used that screen ...

Transcriptional Analysis of the Conjugal Transfer Genes of Rickettsia bellii RML 369-C. [PDF]
Rickettsia bellii is an obligate intracellular bacterium that is one of the few rickettsiae that encode a complete set of conjugative transfer (tra) genes involved in bacterial conjugation and has been shown to exhibit pili-like structures. The reductive genomes of rickettsiae beg the question whether the tra genes are nonfunctional or functioning to ...

Detection of Rickettsia bellii and Rickettsia amblyommii in Amblyomma longirostre (Acari: Ixodidae) from Bahia state, Northeast Brazil. [PDF]
Studies investigating rickettsial infections in ticks parasitizing wild animals in the Northeast region of Brazil have been confined to the detection of Rickettsia amblyommii in immature stages of Amblyomma longirostre collected from birds in the state of Bahia, and in immatures and females of Amblyomma auricularium collected from the striped hog-nosed

Motility characteristics are altered for Rickettsia bellii transformed to overexpress a heterologous rickA gene. [PDF]
ABSTRACT The rickettsial protein RickA activates host cell factors associated with the eukaryotic actin cytoskeleton and is likely involved with rickettsial host cell binding and infection and the actin-based motility of spotted fever group rickettsiae.

Many arthropods host bacterial symbionts, some of which are known to influence host nutrition and diet breadth. Omnivorous bugs of the genus Macrolophus (Heteroptera: Miridae) are mainly predatory, but may also feed on plants. The species M. pygmaeus and

High Prevalence of Rickettsia bellii in Mosquitoes From Eastern China
Abstract Mosquitoes are the most important vectors carrying significant numbers of human pathogens. Recent studies implicated that mosquitoes play an important role in circulation and transmission of multiple Rickettsia species. In this study, Rickettsia bellii was identified in four mosquito species (Culex pipiens, C. tritaeniorhynchus,
