Investigation of the Occurrence of Zoonotic Intestinal Parasites along the Karmanasa River Bank in Lalitpur, Nepal.
Vet Med Sci

Department of Zoology, Tri-Chandra Multiple Campus, Tribhuvan University, Kathmandu, Nepal.
Introduction: Increasing urbanization has particularly affected rivers and their outer edges in cities, including Kathmandu Valley, which encompasses Lalitpur, the nation's third-largest city. This study aims to conduct a parasitological survey to investigate the occurrence of zoonotic intestinal protozoa and helminths along the Karmanasa River bank in central Nepal.
Methods: Faecal samples from openly defaecating animals were collected via non-invasive techniques, and coproscopy was carried out using direct wet mount, concentration and acid-fast staining methods to ensure reliable findings.
Testing the 'parasite-mediated domestication' hypothesis: a comparative approach to the wild boar and domestic pig as model species.

Article Synopsis
- The domestication process has been extensively studied, beginning with Belyaev's experiment on silver foxes, which showed that selecting for tameness disrupts systems controlling development, leading to typical domestication traits.
- Additional hypotheses, like the thyroid rhythm and neural crest cell hypotheses, have been proposed, but the recent parasite-mediated domestication hypothesis (PMD) suggests that endoparasites may play a critical role in this process.
- Research comparing parasite loads in wild boars and domestic pigs from Slovenia and Croatia found different parasite taxa in both populations, providing a basis to explore how parasite susceptibility may have contributed to domestication.
Diversity and Prevalence of Helminths and Protozoa Among Pregnant Women in Tropical Ecuador: Implications for Chemotherapy.

Deworming for pregnant women using a single dose of albendazole or mebendazole is recommended by the WHO in areas where the baseline prevalence of hookworm and/or trichuriasis is >20%. However, other helminths and protozoa infecting pregnant women are not affected by these drugs and dosages. To assess the prevalence and diversity of intestinal helminth and protozoan infections, we analyzed stool samples from pregnant women recently enrolled into a birth cohort, along a rural-urban gradient in northern coastal Ecuador from 2019 to 2022.

The order Testudines comprises some of the most endangered groups of vertebrates. Under specific circumstances, infectious and parasitic diseases may affect the survival and fecundity of these animals, potentially threatening Testudines populations. In Sardinia, besides the three species of tortoises present in the wild (Testudo hermanni, Testudo graeca and Testudo marginata), many others are kept as pets.

Article Synopsis
- The study investigates enteric infections in Arabian camels in Al-Muthanna Province, Iraq, highlighting the importance of understanding normal physiology to study infection-related changes.
- A total of 588 fecal and blood samples were collected over almost a year, revealing previously unrecorded protozoal infections such as Eimeria rajasthani and Isospora orlovi.
- The research indicates that younger camels are more susceptible to Eimeria infections, with higher infection rates seen in October and significant alterations in hematological parameters due to these infections, suggesting potential zoonotic implications.
