Rickettsia felis in Ctenocephalides spp. Fleas, Brazil [PDF]

Emerging Infectious Diseases, 2002
In June 2000, suspected cases of Brazilian spotted fever (BSF) occurred in Coronel Fabriciano Municipality, Minas Gerais State, Brazil. Pooled fleas collected near two fatal cases contained rickettsial DNA. The nucleotide sequence alignment of the 391-bp segment of the 17-kDa protein gene showed that the products were identical to each other and to the

Evolution of the Neopsylla hongyangensis Mitogenome: Insights Into the Mitogenomic Evolution of the Orders Siphonaptera and the Phthiraptera

Ecology and Evolution, Volume 15, Issue 3, March 2025.
The Neopsylla hongyangensis is an important medical insect that transmits plague. We sequenced the mitogenome of N. hongyangensis and constructed a phylogenetic tree for the order Siphonaptera. In addition, we explored the mitogenomic evolution of the orders Siphonaptera and Phthiraptera, which both belong to the class Insects, on warm‐blooded animals ...

Insecticide Resistance in Fleas

Insects, 2016
Fleas are the major ectoparasite of cats, dogs, and rodents worldwide and potential vectors of animal diseases. In the past two decades the majority of new control treatments have been either topically applied or orally administered to the host.

Prevalence and infection load dynamics of Rickettsia felis in actively feeding cat fleas. [PDF]

PLoS ONE, 2008
Rickettsia felis is a flea-associated rickettsial pathogen recurrently identified in both colonized and wild-caught cat fleas, Ctenocephalides felis. We hypothesized that within colonized fleas, the intimate relationship between R. felis and C.

Diversity of lice and flea‐ and lice‐borne pathogens in free‐ranging dogs in Uzbekistan

Medical and Veterinary Entomology, Volume 39, Issue 1, Page 216-222, March 2025.
Lice (Trichodectes canis, Linognathus africanus and Bovicola bovis) and fleas were collected from dogs across five regions of Uzbekistan and subjected to molecular analysis. Molecular screening detected Dipylidium caninum and Bartonella spp. in fleas, while Rickettsia spp. were identified in both fleas and lice.

A crucial active site network of titratable residues guides catalysis and NAD+ binding in human succinic semialdehyde dehydrogenase

Protein Science, Volume 34, Issue 1, January 2025.
Abstract Human succinic semialdehyde dehydrogenase is a mitochondrial enzyme fundamental in the neurotransmitter γ‐aminobutyric acid catabolism. It catalyzes the NAD+‐dependent oxidative degradation of its derivative, succinic semialdehyde, to succinic acid.

Species Composition, Diversity, Abundance, and Phylogeny of Fleas of Small Mammals in Selected Plague‐Endemic and Nonendemic Areas of Tanzania

Journal of Parasitology Research, Volume 2025, Issue 1, 2025.
The remerging nature of plague requires detailed understanding of the plague flea vectors and small mammal reservoir interactions. Therefore, this study is aimed at assessing flea vector composition, diversity, prevalence, abundance, and phylogeny in selected villages of Lushoto, Mbulu, and Morogoro Rural districts in Tanzania.

Comparative Analysis of Gastrointestinal Bacteria in Ctenocephalides felis and Ctenocephalides canis: Biochemical Traits, Antibiotic Resistance, and 16S rRNA Identification

Journal of Pure and Applied Microbiology
Fleas of the genus Ctenocephalides that infest cats and dogs are known to harbor various pathogenic bacteria with potential zoonotic importance. This study aimed to isolate, characterize, and identify bacterial species from the gastrointestinal tracts of
