Article Abstract
Zoonotic opportunistic enteric protozoa represent a significant global health threat to immunocompromised populations, especially individuals with human immunodeficiency virus (HIV). Despite China's severe HIV burden, molecular epidemiological data on enteric protozoa remain limited in this population. In this study, we investigated the occurrence and molecular characteristics of species, , and among 150 AIDS patients with severe immunodeficiency in Wuhan city, Hubei Province, China. The overall test-positive rate was 5.33% (8/150), comprising species (including , and ) in 2.00% (3/150) and (including assemblage A, B, and E) in 3.33% (5/150); was not detected. Notably, this study reports the first identification of the subtype IIcA5G3 in humans in China, certainly indicating possible cross-border transmission. Furthermore, the detection of IIIbA22G1R1c provided additional molecular evidence for chicken-to-human transmission. The finding of assemblage E highlights the underrecognized zoonotic spillover risks to immunocompromised populations. These findings emphasize the diversity of infectious reservoirs, and the need for enhanced national molecular surveillance of these neglected zoonotic enteric protozoa, alongside targeted interventions for vulnerable populations.

Cryptosporidiosis is an enteric infection caused by The severity of the disease depends mainly on the immune status of the host. The infection is self-limited in immunocompetent individuals but in immunocompromised patients, it can be severe and threatening. To provide new insights into a better understanding of the pathogenesis of the infection and the impact of immune modulation on the course of the disease, we used 4 groups of Swiss-Albino mice; dexamethasone (DEX) group, the diabetic group, the DEX-infected group, and the diabetic-infected group.

Coccidiosis is an enteric protozoan parasitic disease that results in significant economic losses due to high mortality and morbidity, particularly in poultry farms run on a deep litter system, as well as the costs associated with its treatment and control. From time to time, several approaches have been adopted for its prevention and control, among which current approaches include the use of anticoccidial drugs, herbal plants, and vaccines. Anticoccidial drugs work well to stop coccidiosis, but their use is limited because some strains are becoming partially or completely resistant to them.

Background: Giardiasis is recognized as the most prevalent enteric protozoal infection worldwide. Although gastrointestinal symptoms are the most common manifestations of giardiasis, several studies have reported cases of urticaria associated with this infection. Urticaria is a common mast cell-dependent disorder characterized by wheals, angioedema, or both.

To examine the effect of early-life infection with on the development of oral tolerance, we developed a low-dose infection model in neonatal mice. infection in neonatal mice results in immunopathology in the colon. IL-1β released during infection blocked the formation of colonic goblet cell associated antigen passages, which normally serve as a conduit for antigen uptake and development of peripheral regulatory T cells (pTregs), responsible for long-term oral tolerance.
