Güldenstädt, 1785, known as the Caucasian squirrel, is a rodent distributed in all geographical regions of Türkiye. The material of this study consists of ectoparasites collected from male found dead on the highway (Karasu, Sakarya, Türkiye). As a result of microscopic examination, the specimens were identified: ticks as Linnaeus, 1758 (larvae and nymph), sucking louses as Ferris, 1923 (female), and fleas as (Schrank, 1803) (female and male).

Article Synopsis
- Fleas significantly affect human and animal health worldwide, prompting a study on the complete mitochondrial genomes of two species: Paradoxopsyllus custodis and Stenischia montanis yunlongensis.
- The genomes measured 15,375 bp and 15,651 bp, containing 37 genes, with an observable preference for AT nucleotide combinations and unique coding features, including incomplete stop codons.
- Phylogenetic analysis indicated a paraphyletic relationship within the Leptopsyllidae family, providing insights into the mitochondrial genome and beneficial genetic markers for identifying and classifying fleas in the Siphonaptera order.
Transcriptional induction of the IMD signaling pathway and associated antibacterial activity in the digestive tract of cat fleas (Ctenocephalides felis).

Background: Fleas are insect vectors that transmit several Gram-negative bacterial pathogens acquired by ingesting infected vertebrate blood. To combat foodborne illness, insect midgut epithelial cells are armed with efficient microbial recognition and control systems, such as the immune deficiency (IMD) pathway that regulates the expression of antimicrobial peptides (AMPs). However, despite their medical and veterinary importance, relatively little is known about the IMD signaling pathway and production of AMPs in the digestive tract of cat fleas (Ctenocephalides felis).

Introduction: The striped hamster, often parasitized by ectoparasites in nature, is an ideal model for studying host-ectoparasite molecular interactions. Investigating the response to ectoparasites under laboratory conditions helps elucidate the mechanism of host adaptations to ectoparasite pressure.
Methods: Using transcriptome sequencing, we analyzed gene expression in striped hamsters after short-term (3 days) and long-term (28 days) flea () parasitism.
Phylogeny and divergence time estimation of the subfamily Amphipsyllinae based on the mitogenome.

Fleas are primarily parasites of small mammals and serve as essential vectors of the transmission of plague. The subfamily Amphipsyllinae (Siphonaptera: Leptopsyllidae) consists of 182 species across 13 genera, widely distributed worldwide. Only two species of Amphipsyllinae have been sequenced for complete mitogenomes to date.
