| chromosome elimination in ctenocephalides orientis (siphonaptera). | somatic and egg squashes of ctenocephalides orientis exhibited a chromosome complement of 2n = 14,xy/xx, whereas the spermatocytes showed 2n = 15,xy1 y2. the sex trivalent was restricted to spermatogenesis; in oogenesis only one sex bivalent was formed. elimination of one of the y chromosomes from the somatic cells was evident. | 1980 | 7471813 |
| pathogens in ectoparasites from free-ranging animals: infection with rickettsia asembonensis in ticks, and a potentially new species of dipylidium in fleas and lice. | vector-borne infections are persistent public health threats worldwide. in recent years, a number of mosquito-borne viruses have emerged or re-emerged to cause major disease outbreaks. other vector-borne pathogens, however, remain understudied and much neglected especially in the developing regions of the world including southeast asia. in this study, the brown dog tick rhipicephalus sanguineus sensu lato, cat louse felicola subrostratus, and cat fleas ctenocephalides felis and ctenocephalides o ... | 2017 | 28969827 |
| ectoparasite infestation patterns of domestic dogs in suburban and rural areas in borneo. | domestic dogs, canis lupus, have been one of the longest companions of humans and have introduced their own menagerie of parasites and pathogens into this relationship. here, we investigate the parasitic load of 212 domestic dogs with fleas (siphonaptera) chewing lice (phthiraptera), and ticks (acarina) along a gradient from rural areas with near-natural forest cover to suburban areas in northern borneo (sabah, malaysia). we used a spatially-explicit hierarchical bayesian model that allowed us t ... | 2012 | 22526293 |
| evidence for a specific host-endosymbiont relationship between 'rickettsia sp. genotype rf2125' and ctenocephalides felis orientis infesting dogs in india. | fleas of the genus ctenocephalides serve as vectors for a number of rickettsial zoonoses, including rickettsia felis. there are currently no published reports of the presence and distribution of r. felis in india, however, the ubiquitous distribution of its vector ctenocephalides felis, makes it possible that the pathogen is endemic to the region. this study investigates the occurrence of rickettsia spp. infection in various subspecies of c. felis infesting dogs from urban areas of mumbai, delhi ... | 2015 | 25884425 |
| integrated morphological and molecular identification of cat fleas (ctenocephalides felis) and dog fleas (ctenocephalides canis) vectoring rickettsia felis in central europe. | fleas of the genus ctenocephalides are the most common ectoparasites infesting dogs and cats world-wide. the species ctenocephalides felis and ctenocephalides canis are competent vectors for zoonotic pathogens such as rickettsia felis and bartonella spp. improved knowledge on the diversity and phylogenetics of fleas is important for understanding flea-borne pathogen transmission cycles. fleas infesting privately owned dogs and cats from the czech republic (n=97) and romania (n=66) were subjected ... | 2015 | 25899079 |
| bartonella and rickettsia in arthropods from the lao pdr and from borneo, malaysia. | rickettsioses and bartonelloses are arthropod-borne diseases of mammals with widespread geographical distributions. yet their occurrence in specific regions, their association with different vectors and hosts and the infection rate of arthropod-vectors with these agents remain poorly studied in south-east asia. we conducted entomological field surveys in the lao pdr (laos) and borneo, malaysia by surveying fleas, ticks, and lice from domestic dogs and collected additional samples from domestic c ... | 2011 | 22153360 |
| a survey of ectoparasitic arthropods on domestic animals in tak province, thailand. | in july 2008 a survey of ectoparasites on domestic animals was conducted in the royal thai army areas of operation along the thai-myanmar border, tak province, thailand. eleven different ectoparasites were collected: two species of hard ticks (ixodidae), three species of fleas (siphonaptera) and 6 species of sucking or chewing lice (2 species each in the suborders anoplura, ischnocera and amblycera) were collected. domestic dogs (canis lupusfamiliaris) (n = 94) were found infested with 2 species ... | 2009 | 19842427 |
