Prevalence of Rickettsia felis in Ctenocephalides felis and Ctenocephalides canis from Uruguay

Annals of the New York Academy of Sciences, 2006
Abstract:  Our aim was to determine the presence of Rickettsia spp. in 66 fleas from Uruguay. Rickettsial DNA was amplified using gltA and ompB PCR primers. Rickettsia spp. were found in 41% of the fleas (25 Ctenocephalides felis and 2 Ctenocephlides canis).

Efficacy of selamectin against adult flea infestations (Ctenocephalides felis felis and Ctenocephalides canis) on dogs and cats

Veterinary Parasitology, 2000
Selamectin was evaluated in eight controlled studies (4 in dogs, 4 in cats) to determine the efficacy of a single topical unit dose providing the recommended minimum dosage of 6mgkg(-1) against Ctenocephalides felis felis and Ctenocephalides canis fleas on dogs and against C. felis on cats.

Effects of azadirachtin on Ctenocephalides felis in the dog and the cat

Veterinary Parasitology, 1998
Azadirachtin-containing neem seed extract is a powerful insect growth regulator, a feeding deterrent and repellent with low toxicity. Unfortunately, azadirachtin degrades rapidly in light, excessive heat or alkalinity. Evaluations of azadirachtin on ectoparasites on animals have been scarce.

Ctenocephalides orientis and Ctenocephalides felis in Thailand : Head geometry by species, sex and geography

Medical and Veterinary Entomology
Abstract Fleas in the genus Ctenocephalides serve as biological vectors or intermediate hosts of microorganisms such as bacteria, rickettsia, protozoa and helminths. Ctenocephalides felis has a worldwide distribution, while

Effects of ultrasonic flea collars on Ctenocephalides felis on cats

Journal of the American Veterinary Medical Association, 1989
SUMMARY Ultrasonic flea collars marketed by 2 companies were evaluated for their ability to reduce flea numbers on cats with experimentally induced flea (Ctenocephalides felis) infestations. The sound output of the collars was evaluated both before and after use to ensure that the collars were functional.

Vector biology of the cat flea Ctenocephalides felis

Trends in Parasitology
Ctenocephalides felis, the cat flea, is among the most prevalent and widely dispersed vectors worldwide. Unfortunately, research on C. felis and associated pathogens (Bartonella and Rickettsia spp.) lags behind that of other vectors and vector-borne pathogens. Therefore, we aimed to review fundamental aspects of C.

Chromosome elimination in Ctenocephalides orientis (Siphonaptera).

Cytobios, 1981
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.
