| molecular ecological insights into neotropical bird-tick interactions. | in the tropics, ticks parasitize many classes of vertebrate hosts. however, because many tropical tick species are only identifiable in the adult stage, and these adults usually parasitize mammals, most attention on the ecology of tick-host interactions has focused on mammalian hosts. in contrast, immature neotropical ticks are often found on wild birds, yet difficulties in identifying immatures hinder studies of birds' role in tropical tick ecology and tick-borne disease transmission. in panama ... | 2016 | 27203693 |
| rickettsia felis, an emerging flea-borne rickettsiosis. | rickettsia felis is an emerging insect-borne rickettsial pathogen and the causative agent of flea-borne spotted fever. first described as a human pathogen from the usa in 1991, r. felis is now identified throughout the world and considered a common cause of fever in africa. the cosmopolitan distribution of this pathogen is credited to the equally widespread occurrence of cat fleas (ctenocephalides felis), the primary vector and reservoir of r. felis. although r. felis is a relatively new member ... | 2016 | 27340613 |
| comparative efficacy of oral administrated afoxolaner (nexgard™) and fluralaner (bravecto™) with topically applied permethrin/imidacloprid (advantix(®)) against transmission of ehrlichia canis by infected rhipicephalus sanguineus ticks to dogs. | the ability of the topical spot-on advantix(®) (50 % permethrin/10 % imidacloprid) to prevent transmission of ehrlichia canis by infected rhipicephalus sanguineus ticks to dogs has previously been reported. the recent market introduction of chewable tablets containing the novel compounds, afoxolaner (nexgard™) and fluralaner (bravecto™) enabled us to conduct a comparative efficacy study with respect to the ability of these three products to block transmission of e. canis by ticks to dogs. the sp ... | 2016 | 27317101 |
| virulence genes of rickettsia rickettsii are differentially modulated by either temperature upshift or blood-feeding in tick midgut and salivary glands. | rickettsia rickettsii, the etiological agent of rocky mountain spotted fever, is transmitted to humans by ticks. during tick feeding, r. rickettsii is exposed to both temperature elevation and components of the blood meal, which have previously been associated with the reactivation of its virulence. these environmental stimuli were also reported to modulate virulence genes of r. rickettsii infecting a set of organs of adult females of its natural vector, amblyomma aureolatum. | 2016 | 27287539 |
| risk factors for bartonella species infection in blood donors from southeast brazil. | bacteria from the genus bartonella are emerging blood-borne bacteria, capable of causing long-lasting infection in marine and terrestrial mammals, including humans. bartonella are generally well adapted to their main host, causing persistent infection without clinical manifestation. however, these organisms may cause severe disease in natural or accidental hosts. in humans, bartonella species have been detected from sick patients presented with diverse disease manifestations, including cat scrat ... | 2016 | 26999057 |
| first identification and description of rickettsioses and q fever as causes of acute febrile illness in nicaragua. | rickettsial infections and q fever present similarly to other acute febrile illnesses, but are infrequently diagnosed because of limited diagnostic tools. despite sporadic reports, rickettsial infections and q fever have not been prospectively studied in central america. | 2016 | 28036394 |
| host body size and the diversity of tick assemblages on neotropical vertebrates. | identifying the factors that influence the species diversity and distribution of ticks (acari: ixodida) across vertebrate host taxa is of fundamental ecological and medical importance. host body size is considered one of the most important determinants of tick abundance, with larger hosts having higher tick burdens. the species diversity of tick assemblages should also be greater on larger-bodied host species, but empirical studies testing this hypothesis are lacking. here, we evaluate this rela ... | 2016 | 27812506 |
| host specificity in a diverse neotropical tick community: an assessment using quantitative network analysis and host phylogeny. | host specificity is a fundamental determinant of tick population and pathogen transmission dynamics, and therefore has important implications for human health. tick host specificity is expected to be particularly high in the tropics, where communities of ticks, hosts and pathogens are most diverse. yet the degree to which tropical tick species are host-specific remains poorly understood. combining new field data with published records, we assessed the specificity of tick-host associations in pan ... | 2016 | 27357506 |
| brazilian spotted fever with an approach in veterinary medicine and one health perspective. | there is increasing interaction between man and pathogens transmitted by arthropods, especially by ticks. it is on this background that a holistic approach stands out, for the sake of public health. brazilian spotted fever is an endemic disease at the country's southeast, with amblyomma sculptum as its major contributor, followed by a. aureolatum and potentially rhipicephalus sanguineus. dogs have been considered sentinels, and in some areas the disease in dogs can precede human disease. conside ... | 2016 | 26881183 |
