| DNA from ticks recovered from 1137 dogs and 133 cats from Ell over Japan were examined for Rickettsia infection by citrate synthase gene (gltA)-based PCR and partial nucleotide sequencing. A total of 91 dog tick samples and 18 cat tick samples showed a single band of the appropriate size in the nested PCR. Sequence analysis was successfully performed on 102 samples. DNA of Rickettsia japonica or closely related Rickettsia spp. strains were detected from 38 licks in 16 prefectures mainly in western Japan. The other 33, detected from 13 prefectures including Hokkaido and Okinawa, were found to be Rickettsia helvetica or closely related strains. A total of 29 DNA that showed highest homology with Rickettsia akari or closely related strains were detected in 19... |

| El objetivo de este estudio fue optimizar una técnica de diagnóstico para rickettsia-PBT, bacteria asociada a la enfermedad cogollo arrepollado del papayo (PBT), basada en la hibridación de ácidos nucleicos no radiactiva (HANS-PBT), y comparar la factibilidad de su uso con respecto a la PCR convencional. Se optimizó un procedimiento de HANS-PBT que permitió la detección específica de hasta 15 pg de ADN del gen sdhA de rickettsia-PBT. La evaluación de 141 controles caracterizados mediante PCR convencional (PCR-PBT), mostró parámetros de desempeño de la HANS-PBT favorables, con una especificidad diagnóstica (ED) de 97,2% y sensibilidad diagnóstica (SD) de 98,5%. Los análisis simultáneos mediante las dos técnicas de 179 muestras colectadas mayormente en... |

| Os carrapatos são ectoparasitas de grande importância na sanidade animal e humana por transmitirem uma grande variedade de agentes patogênicos. Dentre esses patógenos, destaca-se a Rickettsia rickettsii, causadora da Febre Maculosa Brasileira (FMB), uma zoonose de caráter endêmico, que tem como principal vetor os carrapatos do gênero Amblyomma spp. Objetivou-se com este trabalho identificar a presença de Rickettsia spp. em carrapatos do gênero Amblyomma spp. provenientes de uma reserva de mata da cidade de Aquidauana ? MS, Brasil. Foram coletados com auxílio de armadilha de CO2 um total de 40 carrapatos adultos, sendo 38 exemplares de Amblyomma sculptum, um Amblyomma coelebs e um Amblyomma ovale, dentre estes 37 foram processados individualmente pelo teste... |

| A programme of zoosanitary survey of the populations of black-lip pearl oyster (P. margaritifera) has been developed in French Polynesia during 1996 and 1997. Based on histological and ultrastructural examinations, the study of pearl oysters sampled in several pearl farms from the Society Islands, Tuamotu Atolls and Gambler Archipelago, has been particularly turned to enzootic pathological problems. Particular attention has been given to the shell disease and to the necrosis of the adductor muscle, symptoms that had accompanied the mass mortality in 1985.Virus-like particles, about 40 nm in diameter, were detected in membrane bound vesicles from the necrosized muscle tissue. A new Rickettsia-like organism found in epithelial cells of the digestive tubules... |

| Diseases transmitted by ticks have been an important health problem all over the world. Brazilian Spotted Fever (BSF) stands for a serious epidemiological concern due to the high mortality rates pointed out. Capybaras are commonly incriminated as possible reservoirs in the BSF transmission cycle. In the last decades the numbers of these animals raised sharply and they have invaded human areas. They intensify the contact between ticks and humans beings. This study aim is to contribute to the possible role performed for this rodent in the BSF epidemiology in some areas located in Campinas region, São Paulo. Cabybaras infected by rickettsiae of BSF group were studied through the analysis of the frequencies of BSF-group rickettisae antibodies titer = 64 by... |
