A new eimeria species (apicomplexa: eimeriidae) parasitizing commercial chukar partridges (alectoris chukar) in southern ontario
J Parasitol. 2023 Dec 1;109(6):603-614. doi: 10.1645/23-47.ABSTRACTA commercial producer hatching and rearing chukar partridges (Alectoris chukar) in Ontario, Canada had flocks experiencing coccidiosis. Microscopic analysis of Eimeria species isolated from a field sample indicated the presence of 2 distinct oocyst morphotypes; the most abundant species was determined to be Eimeria chapmani, based on oocyst morphology and sequence-based genotyping, and the less abundant, second Eimeria sp. was an undescribed parasite. Oocysts of the unknown Eimeria sp. were large and oval-shaped; dimensions averaged 27.9 μm by 17.0 μm (sh...

A method for isolating and sequencing trypanosome cells to investigate species associations in multiple morphotype infections
J Parasitol. 2023 Dec 1;109(6):592-602. doi: 10.1645/23-34.ABSTRACTTrypanosome infections containing multiple morphologies have been described from all classes of vertebrates, including mammals, birds, non-avian reptiles, amphibians, and fish. These mixed infections make it challenging to evaluate trypanosome diversity, as it is not immediately clear whether the forms present in the bloodstream represent different species or a single pleomorphic species. Amphibians are common hosts for trypanosomes and are often infected by multiple trypanosome morphologies in the bloodstream. Based on morphological observations and life c...

Temperature and salinity affect development of the parasitic sea anemone edwardsiella lineata potentially limiting its impact as a biological control on the ctenophore mnemiopsis leidyi
J Parasitol. 2023 Dec 1;109(6):574-579. doi: 10.1645/23-15.ABSTRACTThe lined sea anemone, Edwardsiella lineata, parasitizes the ctenophore Mnemiopsis leidyi, which is one of the most destructive marine invasive species in the world. Mnemiopsis leidyi is known to tolerate a wide range of environmental conditions. However, the environmental tolerances of its most prominent parasite have never been characterized. Here we determined the effects of temperature (18, 22, 26, and 30 C) and salinity (6, 15, 24, and 33 ppt) on the survival and development of E. lineata from a vermiform parasite to a free-living polyp. At higher temp...

Seroprevalence to schistosoma soluble egg antigen among nomadic pastoralists residing in northern senegal
J Parasitol. 2023 Nov 1;109(6):580-587. doi: 10.1645/22-69.ABSTRACTUrinary and intestinal schistosomiasis are endemic in Senegal, with prevalence heterogeneous throughout the country. Because of their way of life, nomadic pastoralists are not typically included in epidemiological surveys, and data on the prevalence of schistosomiasis in Senegalese nomadic populations are largely non-existent. The purpose of this study was to determine the seroprevalence of schistosomiasis in Senegalese nomadic pastoralists. A modified snowball sampling survey was conducted among 1,467 nomadic pastoralists aged 6 mo and older in 5 districts...

Epidemiology of toxoplasma gondii and neospora caninum infection in goats from aguascalientes, mexico
The objective of this study was to describe the epidemiology of Toxoplasma gondii and Neospora caninum infection by estimating seroprevalence and its association with certain risk factors in goats from Aguascalientes, Mexico. A total of 150 blood samples was taken from 10 farms and serum samples were subjected to enzyme-linked immunosorbent assay indirect test to detect T. gondii and N. caninum antibodies; the association between seroprevalence and some potential risk factors was estimated through logistic regression analysis. The general seroprevalence for T. gondii was 12.6%, observed in the farms in a range of 6.6 to 60...

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...

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...
