Evaluation of Dermacentor species naturally infected with Rickettsia raoultii [PDF]

Clinical Microbiology and Infection, 2009
In the present study, we investigated the efficiency of transovarial transmission and intensity of multiplication of three R. raoultii genotypes in four naturally-infected Dermacentor species. We used the method of experimental modelling of a natural cycle of the metamorphosis of vectors (MEMNCMv) that allows the study of the role of tick species as ...

First Molecular Detection of Human Pathogen Rickettsia Raoultii in Ticks from Republic of Korea [PDF]

Biologia, 2020
AbstractTicks are vector arthropods responsible for the transmission of several pathogenic agents that affect both human and animal health worldwide. In this study our objective was to analyse, using molecular tools, the bacterial community of Dermacentor reticulatus and Haemaphysalis inermis ticks collected in south-eastern Slovakia.

Tick‐borne pathogens in ticks from urban and suburban areas of north‐western Spain: Importance of Ixodes frontalis harbouring zoonotic pathogens

Medical and Veterinary Entomology, Volume 37, Issue 3, Page 499-510, September 2023., 2023
A higher number of ticks was collected in suburban than in urban areas, being Ixodes frontalis the most commonly detected species. The results have significant implications for public health since most Rickettsia spp. detected are zoonotic. This is the first report of the detection of Borrelia spp. and Rickettsia spp.

Expert opinion on the identification, risk assessment, and mitigation of microorganisms and parasites relevant to xenotransplantation products from pigs

Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023
Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...

Mild Infections with Multiple Spotted Fever Grouped Rickettsia Species among Forest Rangers with Tick Bites

Zoonoses, 2023
Tick-borne rickettsiae are increasingly recognized to cause human infections; however, a complete clinical spectrum is lacking. Thus, surveillance study was conducted among forest rangers with tick bites to describe the clinical manifestations.
