A total of 78 HIV seropositive patients were included in the study from January 2004 to March 2006. Enteric protozoan parasitic infections were diagnosed by microscopic examination of stool by fresh wet mount, stool smears stained by modified Z.N., Trichrome and Calcofluor white stains. 20 samples (25.6%) revealed presence ofenteric protozoan parasites.

Introduction: is the most prevalent enteric protozoan parasite causing infectious diarrhea in neonatal calves worldwide with a direct negative impact on their health and welfare. This study utilized next-generation sequencing (NGS) to deepen our understanding of intestinal epithelial barriers and transport mechanisms in the pathophysiology of infectious diarrhea in neonatal calves, which could potentially unveil novel solutions for treatment.
Methods: At day 1 of life, male Holstein-Friesian calves were either orally infected (n = 5) or not (control group, n = 5) with oocysts (in-house strain LE-01-Cp-15).

Background: Inflammatory bowel disease (IBD), a persistent gastrointestinal disease, is featured with impaired gut immunity. Previous studies have demonstrated that tuft cells can regulate the intestinal type 2 immune response by activating downstream ILC2 and Th2 cells and repair gut barrier upon invasion of parasitic helminths, bacteria, protozoans, and enteritis through different chemo-sensing receptors, such as bitter taste receptors. Berberine is a widely used in the treatment of diarrhea in clinic, however the mechanism underlying this effect is not clear.

Background: Giardia duodenalis is a common enteric protozoan parasite that is categorized into eight assemblages (A-H). In particular, assemblages A and B are zoonotic, capable of infecting both humans and animals worldwide, resulting in significant economic losses and public health challenges in epidemic regions. Thus, the development of rapid, accurate and non-laboratory-based diagnostic methods for infected animals is crucial for the effective prevention and control of giardiasis.
