Paleoepidemiology of diphyllobothriosis: cultural and environmental factors affecting adenocephalus intensity and prevalence
J Parasitol. 2023 Dec 1;109(6):565-573. doi: 10.1645/19-115.ABSTRACTPeruvian and Chilean mummies and coprolites provide a source of population-based parasitological information. This is especially true of the fish tapeworm, Adenocephalus pacificus. Our analysis of Chinchorro and Chiribaya mummies and diversified coprolite samples from Chile and Peru show variation in infection. There is a statistically significant difference in prevalence between Chinchorro hunter-gatherer and Chiribaya mixed-subsistence contexts. Furthermore, the most pronounced differences occur between populations within these groups. Chinchorro differe...

Taxonomic reassessment and morphological redescription of nematostrigea serpens annulata (digenea: strigeidae) from osprey in north america
J Parasitol. 2023 Dec 1;109(6):550-558. doi: 10.1645/23-41.ABSTRACTDigenean trematodes in the strigeid genus Nematostrigea are parasites of various birds, most often ospreys (Pandion haliaetus). Nematostrigea currently contains 2 species, Nematostrigea serpens and Nematostigea hepatica. Nematostrigea serpens is divided into 2 subspecies: N. serpens serpens from the Palearctic and Indomalayan realms and N. serpens annulata from the Nearctic realm. In the present work, we studied the type material of N. serpens annulata and collected new specimens from an osprey in Wisconsin close to the type locality. The original descripti...

Population structure and bartonella quintana in head and body lice in pokhara, nepal (anoplura: pediculidae)
This study examined the population structure of head and body lice infesting a random sample of people in Pokhara, Nepal during 2003, 2004, and 2005. A total of 106 participants (6 to 72 yr old, median = 12) volunteered to have lice collected from their heads and clothing. Most participants (70%) harbored only head lice, some (15%) had only body lice, and some (15%) had concurrent infestations of head and body lice (dual infestations). A total of 1,472 lice was collected. Significantly more nymphs were collected than adult lice. Louse populations were generally small (geometric mean = 8.8 lice per person) but a few partici...

Prescribing patterns and the use of anthelmintic drugs in colombian patients: a cross-sectional study
The objective of this study was to determine the use of anthelmintic drugs and their indications in a group of Colombian patients. This was a descriptive study from a drug-dispensing database, identifying patients with prescriptions for anthelmintic drugs. A total of 381 cases were randomly selected, and their medical records were reviewed, analyzing sociodemographic, clinical, and pharmacological variables (indication of use). The lack of diagnosis registration or clinical manifestations of parasites was determined as a prescription without indication. In total, 50.9% (n = 194) of patients were female, and 67.4% of all pa...

Molecular characterization of ornithostrongylus quadriradiatus isolated from a racing pigeon (columba livia domestica)
J Parasitol. 2023 Nov 1;109(6):543-549. doi: 10.1645/22-103.ABSTRACTAn infestation of Ornithostrongylus quadriradiatus, has been found in a racing pigeon Columba livia domestica). In addition, this individual had a mild infection with Trichomonas spp. and Eimeria spp. The bird showed symptoms of increased appetite; unformed, dark- green feces; and lack of typical male behavior, but the general condition of this pigeon was good. The pigeon was euthanized because of a permanent inability to fly due to an injury to the wing. A postmortem examination revealed the presence of very small dark-pink twisted nematodes with the morp...
