Objective: Intestinal parasitic infections are common in immunodeficient patients. In developing countries, the incidence of diarrhea due to parasitic infections in HIV (human immunodeficiency virus)-positive individuals is reported to be over 90%. The present study aimed to investigate the presence of intestinal protozoa in HIV-positive patients with gastrointestinal complaints.
Methods: The fecal samples of 65 HIV-positive patients (14 women, 51 men) were included. Clinical data obtained from patients' files and laboratory results were retrospectively scanned using laboratory information system. Age, sex, parasite positivity, CD4+ count, HIV RNA level, and antiretroviral therapy information were recorded.
Results: Fourteen Cryptosporidium spp. (21.5%), 2 Cyclospora spp. (3.1%), 7 Blastocystis spp. (10.8%), and 1 Cryptosporidium spp.+Blastocystis spp. (1.5%) were detected. The median duration of antiretroviral treatment was 3 months and 12 months in patients with and without parasites in fecal samples, respectively. The duration of antiretroviral treatment was significantly higher in non-infected patients (p=0.002). No significant correlations were found between parasite presence and CD4+ T cell counts or HIV RNA levels.
Conclusion: Our findings suggest that positive effects of antiretroviral therapy on the immune system of HIV-infected patients reduce the risk of intestinal parasitic infection, and thus, this treatment may play an important role in protection.

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.

The mosquito midgut functions as a key interface between pathogen and vector. However, studies of midgut physiology and virus infection dynamics are scarce, and in Culex tarsalis-an extremely efficient vector of West Nile virus (WNV)-nonexistent. We performed single-cell RNA sequencing on Cx.

Intestinal infections affect approximately 450 million people globally, predominantly impacting children and immunocompromised individuals in low- and middle-income countries (LMICs) due to inadequate water, sanitation, and hygiene (WASH) conditions, poverty, malnutrition, and low literacy. In Kenya, the prevalence of intestinal infections is elevated by warm tropical climates and socioeconomic factors. This scoping review evaluates the national prevalence, risk factors, and contamination sources of intestinal protozoa in Kenya, using a One Health approach to synthesize existing data from various human, animal, and environmental studies.

The intestinal microbiota is known to be altered by -induced coccidiosis, but it remains unclear whether the microbiota is fully restored after recovery. To address this, 110 newly hatched Cobb male broiler chickens were challenged with 2 × 10 sporulated oocysts of (EM) strain M6 or mock-infected with saline on day 10. Body weight and feed intake were recorded.

Gastrointestinal nematodes (GINs) inflict significant economic losses on sheep and goat farming globally due to reduced productivity and the development of anthelmintic resistance. Sustainable control strategies are urgently needed including the exploration of medicinal plants as safer alternatives to chemical anthelmintics. This genus of plants is used for anti-inflammatory, antioxidant, and antimicrobial activities.
