1. Rickettsia felis infection in cat fleas Ctenocephalides felis felis
The present study evaluated the rickettsial infection in a laboratory colony of cat fleas, Ctenocephalides felis felis (Bouche) in Brazil. All flea samples (30 eggs, 30 larvae, 30 cocoons, 30 males, and 30 females) tested by polymerase chain reaction (PCR) were shown to contain rickettsial DNA. PCR products, corresponding to the rickettsial gltA, htrA, ompA

2. Activity of neonicotinoid dinotefuran on Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera: Pulicidae) / Atividade do neonicotinóide dinotefuran sobre Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera: Pulicidae)
O presente trabalho teve como objetivo avaliar a atividade do neonicotinóide dinotefuran sobre Ctenocephalides felis felis. As pulgas utilizadas nos testes in vitro e nos testes controlados foram da colônia mantida no Laboratório de Desenvolvimento de Produtos Parasiticidas (LDPP) da UFRRJ, e os nos testes controlados foram utilizados cães Beagle oriundo

3. Experimental transmission of Bartonella henselae by the cat flea.
Bartonella henselae is an emerging bacterial pathogen, causing cat scratch disease and bacillary angiomatosis. Cats bacteremic with B. henselae constitute a large reservoir from which humans become infected. Prevention of human infection depends on elucidation of the natural history and means of feline infection. We studied 47 cattery cats in a private home

4. Typhus and typhuslike rickettsiae associated with opossums and their fleas in Los Angeles County, California.
The recent discovery of cat fleas (Ctenocephalides felis) infected with a typhuslike rickettsia (designated the ELB agent) raises the question of whether similar rickettsial infections exist in wild cat flea populations. We verified the presence of the ELB agent and Rickettsia typhi in urban and suburban areas of Los Angeles, Calif. Opossums trapped in close

5. Rickettsia felis: a new species of pathogenic rickettsia isolated from cat fleas.
A flea-borne rickettsia, previously referred to as ELB, has been implicated as a cause of human illness. Using sequence data obtained from a fragment of the citrate synthase gene, we compared ELB, Rickettsia australis, R. rickettsii, and R. akari with the louse-borne R. prowazekii. We tallied 24 base pair differences between ELB and R. prowazekii and 25 betw

6. Isolation, cultivation, and partial characterization of the ELB agent associated with cat fleas.
ELB rickettsiae from cat flea homogenates were recovered in tissue culture cells following sequential passage through laboratory rats and the yolk sacs of embryonated chicken eggs. Seven days after inoculation of ELB from the infected yolk sacs, Vero cells and L929 cells were observed to contain intracellular bacteria as demonstrated by Diff Quik and indirec

7. Prevalence, Risk Factors, and Genetic Diversity of Bartonella henselae Infections in Pet Cats in Four Regions of the United States
Blood was collected from a convenience sample of 271 pet cats aged 3 months to 2 years (mean age, 8 months, median and mode, 6 months) between May 1997 and September 1998 in four areas of the United States (southern California, Florida, metropolitan Chicago, and metropolitan Washington, D.C.). Sixty-five (24%) cats had Bartonella henselae bacteremia, and 138

8. Efficacy of selamectin in the treatment of naturally acquired cheyletiellosis in cats
The purpose of this study was to evaluate the efficacy of a topical formulation of selamectin in the treatment of cheyletiellosis in cats. Fifteen adult domestic cats from the same household with naturally occurring Cheyletiella sp. infestation were enrolled in the study. On each cat, 45 mg of selamectin was applied on days 0, 30, and 60. No other treatment

9. Cyp12a4 confers lufenuron resistance in a natural population of Drosophila melanogaster
Lufenuron is an insect growth regulator insecticide mainly used for the control of the cat flea. To understand mechanisms of resistance to lufenuron, we have characterized lufenuron resistance in a natural population of Drosophila melanogaster. In this study we have used precise genetic mapping to identify a mechanism of lufenuron resistance: the overexpress
