Data on genus and infectious by Rickettsia were retrospectively compiled from the critical review literature regarding all countries in Latin America, Caribbean islands, Portugal Spain. We considered records reported for human and/or animal hosts, invertebrate hosts being vector. In a few cases, when no direct detection of given group or species was available country, serologic method considered. A total 13 have been recorded America Caribbean. The with largest number country confirmed felis...
Relapsing fever spirochetes are tick- and louse-borne pathogens that primarily afflict those in impoverished countries. Historically the have had a significant impact on public health, yet currently they often overlooked because of nonspecific display disease. In this review, we discuss aspects relapsing (RF) spirochete pathogenesis including the: (1) clinical manifestation disease; (2) ability to diagnose pathogen exposure; (3) pathogen's life cycle tick mammal; (4) ecological factors...
Several outbreaks of Rocky Mountain spotted fever have occurred in recent years Colombian communities close to the border with Panama. However, little is known about rickettsiae and rickettsial diseases eastern Panamanian provinces, Darien Province Kuna Yala, located north endemic area Colombia. In 2007, 289 ticks were collected several towns from dogs, horses, mules, cows, pigs. DNA was extracted 124 Dermacentor nitens, 64 Rhipicephalus sanguineus, 43 Amblyomma ovale, 35 A. cajennense, 10...
A new species of argasid tick (Acari: Argasidae) is described from immature and adult specimens collected several localities in Brazil. complete morphological account provided for all postembryonic life stages, i.e., larva, nymph, female, male. Ornithodoros cavernicolous n. sp. the 113th genus. Morphologically, shares common features, e.g., presence well-developed cheeks legs with micromammillate cuticle, other bat-associated ticks included subgenus Alectorobius. In particular,...
Host specificity is a fundamental determinant of tick population and pathogen transmission dynamics, therefore has important implications for human health. Tick host expected to be particularly high in the tropics, where communities ticks, hosts pathogens are most diverse. Yet degree which tropical species host-specific remains poorly understood. Combining new field data with published records, we assessed tick-host associations Panama, diverse Neotropical region. The resulting dataset...
Abstract Background Tick-borne relapsing fever (TBRF) is a globally prevalent, yet under-studied vector-borne disease transmitted by soft and hard bodied ticks. While TBRF (sTBRF) spirochetes have been described for over century, our understanding of the molecular mechanisms facilitating vector host adaptation poorly understood. This due to complexity their small (~ 1.5 Mb) but fragmented genomes that typically consist linear chromosome both circular plasmids. A majority sTBRF spirochete...
Rocky Mountain spotted fever (RMSF) is a tick-borne infection caused by Rickettsia rickettsii. We report cluster of fatal cases RMSF in 2007 Panama, involving pregnant woman and two children from the same family. The presented with followed respiratory distress, maculopapular rash, an eschar at site which tick had been removed. She died four days after disease onset. This second published patient confirmed PCR to be infected R. One month later, within one another rash three diagnosis was...
Fleas and ticks are parasites of wild domestic mammals, can be vectors several pathogens. In rural areas, carnivores such as the dog (Canis lupus familiaris L.), may act a "bridge" between natural areas human settlements where ectoparasites used metric link. The aim this study was to identify fleas, ticks, Rickettsia spp., collected from in reserve surrounding Central Chile, using morphological keys molecular analysis. We surveyed 170 households which 107 dogs eight cats were sampled. From...
The Rhipicephalus sanguineus group encompasses at least 12 validated species of Palearctic and Afrotropical hard ticks, which are relevant in veterinary medicine public health. taxonomy R. s.s., has been particularly intensely debated, due to its wide geographic distribution, morphological variants, parasite-host associations, capacity vectorial competence for the transmission several pathogens. By sequencing mitochondrial markers, it was possible identify existence multiple lineages, among...
We aim to provide a harmonized view of the factors that affect survival and promote spread R. microplus in Neotropics, approaching its different facets biology, ecology, distribution, control. review interactions among environmental niche, landscape fragmentation, vegetal coverage (abiotic traits), biotic aspects ecology (abundance domesticated or wild competent hosts), proposing emerging areas research. emphasize holistic integrating an economically ecologically sustainable control...
Ixodes chacoensis n. sp. is described based on males, females, nymphs and larvae collected from vegetation, ungulates passerine birds in northeastern Argentina. affinis Neumann, 1899 redescribed the original type specimens (females) Leopardus pardalis, recently Costa Rica. keiransi sp., previously treated as North American populations of affinis, males females carnivores southeastern United States. Concatenated total evidence phylogenetics combined DNA sequence analyses mitochondrial genes...
In this paper, we report the mite, Archegozetes magnus immatures and females, in non-parasitic interactions with Bishop's Toad, Rhinella alata (Anura: Bufonidae), Buthidae scorpions Tityus jaimei festae. The reports both species of represent news phoretic interactions. Possible behavior is discussed.
Abstract The clinical and pathologic characterisation of two fatal cases tick-borne rickettsiosis in rural (El Valle) urban (City Panama) Panama are described. Clinical autopsy findings were non-specific, but the molecular analysis was used to identify Rickettsia rickettsii both cases. No ticks collected El Valle, while case, R. detected Rhipicephalus sanguineus s.l., representing first finding this tick Central America.
The first molecular screening for Rickettsia, Anaplasma, Ehrlichia, Borrelia, Babesia and Hepatozoon was carried out in questing Ixodes cf. boliviensis tapirus from Talamanca Mountains, Panama, using specific primers, sequencing phylogeny. Phylogenetic analyses the microorganisms confirmed presence of Rickettsia sp. strain IbR/CRC endosymbiont (26/27 ticks), three genotypes Borrelia burgdorferi (sensu lato) complex (4/27 odocoilei (1/27 (2/27 tentatively designated Chiriquensis. I. revealed...
