Objective: To determine the prevalence, severity and pattern of intestinal parasitic infestation in HIV-seropositive patients.
Methods: A Cross-sectional study from January 2007 to December 2008.Patients were recruited from the HIV clinics of the hospital. Paired blood and single stool specimens were collected from each patient. The stool sample was investigated for intestinal parasites while the blood sample was tested for antibodies to HIV-1 and 2. HIV-seropositive subjects also had CD4 + cells count done.
Result: Ninety each of stool and blood samples were collected from HIV-seropositive and HIV-seronegative patients. Four species each of helminthes and protozoan parasites and three species of coccidian parasites were isolated from the stool of both HIV-seropositive and seronegative subjects. The prevalence of these parasites was two and a halve times higher among the HIV seropositive patients than the seronegative ones. The range of CD4 cells count was 20-680 cells/microl with a median of 259 cells/microl. Patients with CD4+ count <200/microl had more coccidian parasites in their stool and also had higher prevalence of intestinal polyparasitism ranging from 2 to 4 different species per stool sample.
Conclusion: The frequency of both AIDS defining and non- AIDS defining intestinal parasitic infestation was higher among the HIV infected patients. Patients' CD4+ cells count was an important determinant of the rate and number of parasitic infestation.

Haplorchis taichui is the minute intestinal fluke (MIF), presents a significant public health concern in Thailand. Despite praziquantel (PZQ) being the main treatment, concerns over recurrent use and drug resistance have surfaced. Thus, local herbal alternatives effective against gastrointestinal parasites could be crucial for reducing issues, necessitating exploration of herbal sources for alternative treatments.

Migratory birds are potential vectors transmitting zoonotic parasites, bacteria, and viruses that can significantly affect human health. Over 60 diseases have been identified to be associated with these birds. Given their close proximity to human habitation, the potential transmission of zoonotic diseases is a major concern for the public.

The aim of this study was to investigate whether Trypanosoma vivax is transmitted via rectal palpation in cattle, using the same glove with different blood scores, from an animal with an acute infection of this protozoan. In addition, the efficacy of iodine as disinfectant, together with water with or without the presence of feces, to prevent the transmission of T. vivax in cattle during the rectal palpation process was evaluated in the laboratory and animals.

Globally, an estimated 1 billion people reside in endemic areas, and over 12 million individuals are infected with leishmaniasis. Despite its prevalence, leishmaniasis continues to be a neglected disease, mainly affecting underdeveloped countries. In Brazil, the available treatments are pentavalent antimonials and Amphotericin B, which are outdated, toxic, require prolonged parenteral administration and have limited efficacy.

The nutria (Myocastor coypus) is a semiaquatic rodent that originally inhabited South America. However, the animals have spread to different continents as alien species, and their numbers are quickly increasing, especially in North America, Europe, and Eastern Asia including Japan. Although nutrias have been suggested to serve as reservoirs for pathogens, including parasites, there have been few reports on this subject.
