Little is known about the genetic diversity of Sarcoptes scabiei mites in farm animals in Egypt. In this study, we characterized S. scabiei in 25 skin scrapes from water buffalo, cattle, sheep, and rabbits at the nuclear marker ITS2 and mitochondrial markers COX1 and 16S rRNA. Sequences of the ITS2 showed no host segregation or geographical isolation, whereas those of the mitochondrial COX1 and...

Identification of species members of the Hyrcanus Group of Anopheles is difficult because of intraspecific variation in and interspecific similarity among key characters. Hibernating female Anopheles pullus were collected and 6 adults were individually reared. All F1 progeny of wild-caught An. pullus were morphologically identical to An. yatsushiroensis. The 5.8S rDNA-ITS2-28S rDNA region from ...

Dorsal-spined protostrongylid nematode larvae (Metastrongyloidea: Protostrongylidae) were recovered from the feces of the endangered pampas deer (Ozotocerus bezoarticus celer) in Campos del Tuyú Wildlife Reserve, Bahia Samborombón, Argentina. Partial DNA sequences from the large subunit ribosomal RNA (LSU rRNA) gene and from the second internal transcribed spacer region (ITS2) were amplified, c...

A species-specific polymerase chain reaction (PCR) assay using primers already designed, based on differences in the nucleotides of the second internal transcribed spacer (ITS2), was used to identify the species composition of the Anopheles fluviatilis complex in Iran. All the amplified DNA samples obtained from specimens collected from different areas using different collection methods yielded...

Anopheles fluminensis Root is a member of the Arribalzagia Series in the subgenus Anopheles. We report the first record of this species in the department of Cochabamba, Bolivia. This species was sampled from two locations in the foothills of the eastern Andes Mountains within the Chapare Valley. Larvae were collected in fast-flowing, shaded streams at the edges of rocky pools. We provide the fi...
