The Brazilian Spotted Fever (BSF) is a zoonotic disease caused by Rickettsia rickettsii and transmitted ticks of the genus Amblyomma, more frequently, Amblyomma cajennense. aim this paper was to report first molecular detection R. on sanguineus naturally infected in Rio de Janeiro, Brazil. Ticks were collected from dogs rural region Resende municipality, Janeiro State, Brazil (22º30'9.46"S, 44º42'44.29"WO), where occurred five human cases BSF 2006. identified under stereoscopic microscope...
Hoplias malabaricus (Characiformes, Erythrinidae), trahira, is a neotropical freshwater fish of economic and public health significance. A total 45 specimens H. commercialized in the municipality Magé, state Rio de Janeiro, Brazil, were acquired between April 2016 2018 to investigate presence nematode larvae. Twenty found parasitized by 347 fourth-stage larvae identified taxonomically as Eustrongylides sp. using morphological, morphometric molecular data. The parasitic indices were:...
Resumo Estudos têm revelado que a resistência às quinolonas em cepas de Campylobacter está relacionada à presença da mutação Treonina-86 para Isoleucina. Com o objetivo investigar dessa sensíveis e resistentes ciprofloxacina enrofloxacina, conteúdo cecal 80 frangos corte criação orgânica, abatidos sob Serviço Inspeção Estadual (S.I.E.) do Estado Rio Janeiro, foram coletados investigados Campylobacter. A determinação enrofloxacina foi feita pela técnica difusão disco diluição ágar...
Some tick species have been described parasitizing buffaloes, but reports from Brazil are rare. This study aimed to ascertain the of ticks that parasitize buffaloes in state Rio de Janeiro. Seventeen farm properties were visited between June 2008 and December 2009, inspected relation infestation. The identified a semi-structured questionnaire on parasitism treatment against was filled out through interviews with owners. Rhipicephalus (Boophilus) microplus, Dermacentornitens...
ABSTRACT The present paper is the first to perform this evaluation in dogs from cities of Natividade, Porciuncula and Varre-Sai. aim study search for Spotted Fever Group Rickettsia canine sera using indirect immunofluorescence assay identify probable causative agent reactions animals. Of 253 sampled canines, 67.59% (171/253) were seroreactive rickettsii 11.07% (28/253) parkeri, both dilution 1:64. Titration tested against R. antigens reached 1:131.072 and, 1:4.096. We conclude that are...
Rickettsia rickettsii is the causative agent of Brazilian spotted fever (BSF), for which humans and dogs are both susceptible. Dogs sentinels in serological surveys, however, canine disease rarely reported. Therefore, we aimed to evaluate natural infection by group (SFG) spp. ticks collected from domiciles close forest fragments, featuring domestic-wildlife interface areas. Samples 115 135 ixodids were assessed polymerase chain reactions (PCR) targeting gltA gene ompA SFG rickettsial...
Background: Changes in glycemic levels can negatively affect the body. Several techniques for measurement of blood glucose have been described, but enzymatic method is considered standard and more accurate both humans animals. The College American Pathologists recommends use portable glucometers (PGs), which are routinely used human medicine because this an easy, relatively inexpensive that delivers results quickly. aim study was to compare cattle obtained using Accu-Check® glucometer with...
Borrelia burgdorferi é uma espiroqueta transmitida por carrapatos, de ampla distribuição geográfica, que acomete o homem e animais domésticos, tendo os silvestres como reservatórios.O presente estudo teve objetivo relatar a ocorrência eqüinos soropositivos para B. burgdorferi, meio inquérito soroepidemiológico utilizando ensaio imunoadsorção enzimática (ELISA) indireto.Procedeu-se análise sorológica 747 soros eqüinos, onde 431 pertenciam ao município Três Rios 316 Vassouras, ambos do estado...
The present study aimed to adjust the artificial feeding technique through capillaries and verify its influence over biology of Amblyomma cajennense females. Five groups 20 female ticks were formed. Females starved for 45 days then fed with citrated bovine blood using capillary tubes in different periods time. divided five experimental individuals each as follows: uninterruptedly 12, 24, 48 hours 2 6 h a day, period 8 days. Subsequently, exposed rabbits complementary their biological...
Borreliose aviária é uma doença septicêmica aguda, cosmopolita, que acomete diferentes espécies aviárias, sendo causada por Borrelia anserina Sakharoff, 1891. O objetivo do presente trabalho foi avaliar as alterações hematológicas em Gallus gallus domesticus experimentalmente infectados B. via vetor Argas (Persicargas) miniatus. Um total de 27 aves da espécie G. g. com 67 dias vida, foram divididas três grupos inteiramente casualizados contendo nove animais cada. grupo exposto a carrapatos...
Borrelia burgdorferi, the agent of Lyme borreliosis, is a spirochetes transmitted by ticks to humans and animals. Its cultivation in vitro tick cells allows studies its biology provides methodology for future research Brazil, isolation spp. We examined characteristics embryonic Rhipicephalus microplus Amblyomma cajennense cell culture investigated suitability as substrate B. burgdorferi. Subcultures were prepared from primary cultures embrionary R. A. maintained Leibovitz's (L-15) complete...
Abstract Spotted fever group rickettsioses are emerging diseases. In some of these diseases, domestic dogs act as sentinels. Canine serological studies have demonstrated that rickettsial dispersion is concentrated in rural areas, seroprevalence being higher where human endemic. Rio de Janeiro, the Atlantic forest vegetation has been devastated by urbanization. this context, we aimed to detect Rickettsia spp. urban areas West Zone Janeiro. Sera from 130 were tested Indirect Immunofluorescence...
RESUMO: Doenças causadas por rickettsias tem ampla distribuição geográfica e estão associadas a artrópodes hematófagos. Rickettsia rickettsii é espécie mais patogênica do Grupo da Febre Maculosa (GFM) responsável pela Brasileira. No sudeste país doença endêmica inquéritos sorológicos demonstrado presença de anticorpos para antígenos GFM em cães, reforçando participação cão como sentinela. Os principais vetores são carrapatos gênero Amblyomma, cujos hospedeiros são, muitas vezes, animais vida...
Cestodes of the order Trypanorhyncha can frequently be found infecting muscles several marine fish species, and lead to a repugnant aspect rejection by consumers. The Brazilian sardinella, Sardinella brasiliensis, occurs from Gulf Mexico Caribbean northern Uruguay. In southeastern Brazil, fishing for species is very intensive since it generates significant revenue as one most commonly consumed an important element canned industry. aims present study were identify report occurrence tiny...
ABSTRACT Mycoplasma bovis is a highly contagious agent associated with several pathologies in cattle. The detection of reactive antibodies to M. by Indirect Enzyme-Linked Immunosorbent Assay (iELISA) identifies if there was an exposure the microorganism. current study aimed optimize iELISA from total cell antigen, applying it bovine serum samples, and evaluate risk factors. Serum samples were obtained 400 cows 17 herds Southeast Brazil. In optimization iELISA, following established: 2 μg/mL...
