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.

Causes of pregnancy arrest in the canine species

Reproduction in Domestic Animals, Volume 58, Issue S2, Page 72-83, September 2023., 2023
Abstract In the canine species, early pregnancy arrest before 30–40 days of pregnancy will induce intra‐uterine embryonic or foetal resorption, with very few clinical signs. If no genital examination by ultrasound is performed at that time, it will often remain unnoticed and the bitch will be qualified as infertile. It is only when pregnancy stops at a

Exotic Rickettsiae in Ixodes ricinus: fact or artifact? [PDF]

, 2010
Several pathogenic Rickettsia species can be transmitted via Ixodes ricinus ticks to humans and animals. Surveys of I. ricinus for the presence of Rickettsiae using part of its 16S rRNA gene yield a plethora of new and different Rickettsia sequences ...

Spotted Fever Group Rickettsiosis on Awaji Island, Japan

Journal of the Japanese Association for Infectious Diseases, 1990
Three cases of spotted fever group rickettsiosis occurring on Awaji Island, Hyogo Prefecture, the first reported in the Kinki District, are described. The illness appeared from August to September in 1988. High-grade fever and papular erythema were observed in all cases. Eschar, lymphadenopathy and hepatomegaly were observed in two-thirds of the cases,

Seroconversions for Coxiella and Rickettsial Pathogens among US Marines Deployed to Afghanistan, 2001–2010

Emerging Infectious Diseases, 2016
We assessed serum samples from 1,000 US Marines deployed to Afghanistan during 2001–2010 to find evidence of 4 rickettsial pathogens. Analysis of predeployment and postdeployment samples showed that 3.4% and 0.5% of the Marines seroconverted for the ...

Spotted Fever Group Rickettsiosis and Vectors in Kanagawa Prefecture

Journal of the Japanese Association for Infectious Diseases, 1996
Primer pairs for PCR were designed from the gene encoding the 17,000-molecular-weight genus-common antigen of Rickettsia japonica, Rickettsia rickettsii, Rickettsia conorii, Rickettsia typhi and Rickettsia prowazekii. Primers R1, R2 were designed for amplifying the genomic DNA from spotted fever group (SFG) rickettsiae and epidemic typhus rickettsiae ...

OCCURRENCE OF RICKETTSIOSIS OF SPOTTED FEVER GROUP IN CHIBA PREFECTURE OF JAPAN

Japanese Journal of Medical Science and Biology, 1988
Acute- and convalescent-phase sera were obtained from a patient with suspected tsutsugamushi disease in July 1987, in Amatsukominato located in the southeastern area of Chiba Prefecture, and showed negative serologic reactions with Rickettsia tsutsugamushi, while the convalescent-phase serum reacted positively with R.
