| a reverse vaccinology approach to the identification and characterization of ctenocephalides felis candidate protective antigens for the control of cat flea infestations. | despite the abundance of the domestic cat flea, ctenocephalides felis (bouché, 1835) and disease risks associated with them, flea control is difficult and requires the development of new control interventions such as vaccines. in this study, a reverse vaccinology approach was designed to achieve a rational selection of cat flea candidate protective antigens. | 2018 | 29347954 |
| parasite spread at the domestic animal - wildlife interface: anthropogenic habitat use, phylogeny and body mass drive risk of cat and dog flea (ctenocephalides spp.) infestation in wild mammals. | spillover of parasites at the domestic animal - wildlife interface is a pervasive threat to animal health. cat and dog fleas (ctenocephalides felis and c. canis) are among the world's most invasive and economically important ectoparasites. although both species are presumed to infest a diversity of host species across the globe, knowledge on their distributions in wildlife is poor. we built a global dataset of wild mammal host associations for cat and dog fleas, and used bayesian hierarchical mo ... | 2018 | 29307305 |
| comparison of zoonotic bacterial agents in fleas collected from small mammals or host-seeking fleas from a ugandan region where plague is endemic. | fleas (n = 407) were collected from small mammals trapped inside huts and surroundings of homesteads in five villages within the arua and zombo districts of uganda. the most common flea species were dinopsyllus lypusus (26%) and xenopsylla cheopis (50%). off-host fleas (n = 225) were collected inside huts by using kilonzo flea traps. the majority of the off-host fleas were ctenocephalides felis (80%). all fleas were examined for the presence of bartonella spp., rickettsia spp., and yersinia spp. ... | 2017 | 29276773 |
| cat fleas (ctenocephalides felis) carrying rickettsia felis and bartonella species in hong kong. | fleas are commonly recorded on stray as well as domestic dogs and cats in hong kong. fleas can be a major cause of pruritus in dogs and cats and also vectors of potentially zoonotic bacteria in the genera rickettsia and bartonella. morphological examination of 174 fleas from dogs and cats living in hong kong revealed only cat fleas (ctenocephalides felis). cytochrome c oxidase subunit 1 gene (cox1) genotyping of 20 randomly selected specimens, revealed three cox1 haplotypes (hk-h1 to hk-h3). the ... | 2017 | 29217417 |
| prevalence and seasonality of fleas associated with california ground squirrels and the potential risk of tularemia in an outdoor non-human primate research facility. | ectoparasites at primate research centers may be difficult to control, e.g. without exposing non-human primates (nhps) to toxicants, but their impact on nhp health is poorly understood. in 2010, there was an epizootic of tularemia at the california national primate research center (cnprc) in yolo county, california that resulted in 20 confirmed and suspect clinical cases in outdoors housed rhesus macaques (macaca mulatta [zimmermann]) and a 53% seroprevalence in the southern section of the colon ... | 2017 | 29202201 |
| season-long control of flea and tick infestations in a population of cats in the aeolian archipelago using a collar containing 10% imidacloprid and 4.5% flumethrin. | cats that have outdoor access are highly exposed to ticks, fleas, mites and flying insects, though the risk to become infested by arthropods is less perceived in cats than in dogs. this has resulted in fewer treatment and prevention options being available for cats than for dogs. a collar containing a combination of 10% imidacloprid and 4.5% flumethrin (seresto®, bayer animal health) is available for cats and licensed with claims against ticks and fleas for 7-8 months. following the assessment o ... | 2017 | 29173546 |
| effect of naturally occurring wolbachia in anopheles gambiae s.l. mosquitoes from mali on plasmodium falciparum malaria transmission. | a naturally occurring wolbachia strain (wanga-mali) was identified in mosquitoes of the anopheles gambiae complex collected in the malian villages of dangassa and kenieroba. phylogenetic analysis of the nucleotide sequence of two 16s rrna regions showed that wanga-mali clusters with wolbachia strains from supergroup a and has the highest homology to a wolbachia strain isolated from cat fleas (ctenocephalides). wanga-mali is different from two wolbachia strains previously reported in a. gambiae f ... | 2017 | 29114059 |
| th1/th2 immune responses and oxidative stress in caprine flea allergy dermatitis. | flea allergy dermatitis (fad) is the common, often neglected skin disease of goats caused mainly by ctenocephalides felis. this study aimed to evaluate the immuno-oxidative pathobiology of fad in goats. twelve goats from the same herd were divided into two groups of six animals each. the group i (fad) included animals with natural flea infestation and severe dermatitis lesions. the group ii (healthy control) animals were free from any parasitic infestation. to assess the pathological changes, th ... | 2017 | 29094355 |

| the cat flea (ctenocephalides felis) immune deficiency signaling pathway regulates rickettsia typhi infection. | rickettsia species are obligate intracellular bacteria with both conserved and lineage-specific strategies for invading and surviving within eukaryotic cells. one variable component of rickettsia biology involves arthropod vectors: for instance, typhus group rickettsiae are principally vectored by insects (i.e., lice and fleas), whereas spotted fever group rickettsiae are exclusively vectored by ticks. for flea-borne rickettsia typhi, the etiological agent of murine typhus, research on vertebrat ... | 2018 | 29084898 |
| potential exposure of humans to rickettsia felis in greece. | rickettsia felis is a flea-transmitted pathogen however, in greece, much work has been done on another flea-borne pathogen, r. typhi; human cases have been described and high-risk areas have been characterized. nevertheless, little is known about human infections caused by r. felis in the country since human cases are not routinely tested for antibodies against this pathogen. during the past seven years, we have set up a protocol at the national reference centre in order to improve the testing o ... | 2018 | 29079185 |
