Department of Medical Laboratory Sciences, College of Health Sciences, University of Duhok, Iraq.
The present study aimed to determine the prevalence rate of intestinal protozoan infection among children in Duhok Province, North of Iraq, from October 2022 to May 2023. This cross-sectional study was conducted on 740 children attending Hevi Pediatric Hospital, Duhok Province, Iraq. Firstly, all collected stool samples were examined directly by preparing a wet stool smear for the detection of the vegetative stage (Trophozoite) of both and lamblia.

Background: Campylobacter, nontyphoidal Salmonella, Cryptosporidium, and Giardia cause an estimated 1 million cases of domestically acquired waterborne diseases annually in the United States. Acute symptoms can include diarrhea and vomiting; however, these illnesses can result in longer term complications such as reactive arthritis, Guillan Barré syndrome and death, particularly in immunocompromised individuals. Precipitation and drought can plausibly increase the risk of enteric infections, but consensus in the literature is lacking.

Article Synopsis
- - The study analyzed feces from 348 cats in Jordan, finding Giardia duodenalis in 27.9% of tested cats, Entamoeba histolytica in 0.6%, and no cases of Cryptosporidium.
- - Higher rates of Giardia infection were observed in cold semiarid regions (67%) compared to cold desert areas (24%), with indoor and outdoor cats showing similar infection rates.
- - Most Giardia infections were identified as zoonotic assemblage B, with a possible new mutation in the gene associated with this type, suggesting potential risks for zoonotic transmission from cats to humans.
Enhancing diagnostic accuracy: Direct immunofluorescence assay as the gold standard for detecting Giardia duodenalis and Cryptosporidium spp. in canine and feline fecal samples.

Article Synopsis
- Giardia duodenalis and Cryptosporidium spp. are common parasites causing diarrhea in young dogs and cats, prompting a study that compares various diagnostic methods in 328 fecal samples from both species.
- The study found a higher prevalence of G. duodenalis in dogs (30.2%) than in cats (11.6%), while Cryptosporidium spp. was found in 4% of the total samples, with similar rates in both species.
- The research indicates that direct immunofluorescence assay (DFA) is the most sensitive method for detecting G. duodenalis, and combining DFA with PCR is best for Cryptosporidium detection, with factors like sex and breeding history influencing infection rates

Article Synopsis
- Diarrhea caused by zoonotic pathogens is a major health concern for dairy calves and poses risks to humans, especially children.
- A study conducted on 343 fecal samples from calves in China found a 91% positive rate for various pathogens, with *Clostridium perfringens* being the most prevalent at 61.5%.
- Coinfections were common, with 67.3% of samples containing two to five different pathogens, and the research identified significant variations in pathogenic presence related to farm, age, and season.
