Spotted fever in Argentina. Description of two clinical cases.

[Spotted fever in Argentina. Description of two clinical cases]. Rev Argent Microbiol. 2019 Mar 27;: Authors: Armitano RI, Guillemi E, Escalada V, Govedic F, Lopez JL, Farber M, Borras P, Prieto M Abstract Rickettsioses are zoonotic tick-borne diseases. In Argentina, there are two epidemiological scenarios: jungle of Salta and Jujuy, involving vectors from the "Amblyomma cajennense Complex" (A. sculptum, and A. toneliae) and Rickettsia rickettsii as the main etiological agent; and the second scene to Delta del Rio Paraná and Samborombón Bay, where Amblyomma triste acts as a vector; and the provinces of Córdoba, La Rioja, San Luis and La Pampa where Amblyomma tigrinum is the vector. In this second scenario, Rickettsia parkeri is the causal agent. The spotted fever (SF) due to R. rickettsii is responsible for a severe cutaneous and systemic disease. Contrarily, R. parkeri produces benign and self-limited clinical manifestation. Here we describe a fatal SF case by R. rickettsii, in El Tunal, Salta and the first SF case due to R. parkeri in San Juan. PMID: 30928146 [PubMed - as supplied by publisher]

This study assessed the prevalence, risk factors, and co-infectivity of CTBP such as piroplasms, rickettsiae, Coxiella burnetii, hepatozoa, hemotropic mycoplasmas, and Borrelia spp., using PCR and phylogenetic analyses. Of the 510 dogs tested, three CTBP, including Anaplasma phagocytophilum 16S rRNA (13; 2.6%), Hepatozoon canis 18S rRNA (2; 0.4%), and Mycoplasma haemocanis 16S rRNA (1; 0.2%) were detected. PCR adapted to amplify A. phagocytophilum msp2 and groEL genes generated amplicons thereof in two out of 13 positive dogs. One shelter dog was co-infected with A. phagocytophilum and M. haemocanis. However, Ehrlichia spp...

Publication date: Available online 6 December 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Hein Sprong, Sander Moonen, Sipke E. van Wieren, Tim R. HofmeesterAbstractCattle grazing has been suggested to reduce the risk for Lyme borreliosis by decreasing the density of questing Ixodes ricinus infected with Borrelia burgdorferi sensu lato. We tested the hypotheses that cattle grazing used in woodland management decreases the density of questing I. ricinus, and that it decreases the nympal infection prevalence of B. burgdorferi sensu lato. We further expected the nympal infection prevalence of tick-borne pathogens that ...

ConclusionsIt is of great importance to continue monitoring the disease since it appears to be endemic throughout Spain. There is a need for a common strategy on monitoring and reporting, which would facilitate a more accurate picture on the MSF epidemiological scenario. Entomological information will be of added value.

Abstract The genus Anaplasma currently comprises 6 bacterial species mostly pathogenic to animals and/or human, including the zoonotic species Anaplasma phagocytophilum, the causative agent of tick-borne fever (TBF) of ruminants, and of granulocytic anaplasmosis of horses, dogs and human. Recently, novel potentially non-pathogenic strains related to A. phagocytophilum have been identified in Japan, China, and Tunisia. This paper reports the identification, molecular typing, and evolutionary history of novel Anaplasma strains (A. phagocytophilum-like 1 and 2), related to but distinct from A. phagocytophilum in Medi...

The common tick Ixodes ricinus and the taiga tick I. persulcatus are the main tick vectors of Borrelia spirochaetes, TBE virus (TBEV) and of several other zoonotic pathogens in the western and eastern areas, resp...

In conclusion, dogs were shown to be a host of the human pathogenic A. capra. Considering the affinity between dogs and humans and the zoonotic tick-borne nature of A. capra, dogs should be carefully monitored for the presence of A. capra.

AbstractPurpose of ReviewIn this review, we present the overview of emerging and neglected viruses associated with liver involvement.Recent FindingsHepatitis E virus (HEV) emerged in the last two decades, causing hepatitis in many parts of the world. Moreover, liver involvement was also described in some emerging arboviral infections. Many reports showed dengue-associated liver injury; however, chikungunya, West Nile, tick-borne encephalitis, and Zika virus are rarely associated with clinically manifest liver disease. In addition, some neglected highly prevalent viruses such as adenoviruses and parvovirus B19 are capable o...

eer Wernike Tick-borne encephalitis is the most important tick-transmitted zoonotic virus infection in Eurasia, causing severe neurological symptoms in humans. The causative agent, the tick-borne encephalitis virus (TBEV), circulates between ticks and a variety of mammalian hosts. To study the interaction between TBEV and one of its suspected reservoir hosts, bank voles of the Western evolutionary lineage were inoculated subcutaneously with either one of eight TBEV strains or the related attenuated Langat virus, and were euthanized after 28 days. In addition, a subset of four strains was characterized in bank voles ...

This study aimed to develop a rapid, sensitive and reliable duplex real-time PCR assay for the specific detection and differentiation of these Anaplasma species.We designed primers and probes against the conserved regions of A. capra groEL and A. phagocytophilum 16S rRNA genes. A range of PCR-related parameters were evaluated such as the dosage of primers and probes, and annealing temperature. The specificity, sensitivity and repeatability of this assay were evaluated. Assay performance was further evaluated using samples collected from 124 goats in four regions of Henan, China. This set of samples was also tested using co...
