Article Synopsis
- The study evaluates the prevalence and genetic diversity of Giardia cysts in patients at public hospitals in Shiraz, Iran, identifying waterborne disease risks associated with poor sanitation.
- From 614 stool samples collected, Giardia cysts were found in 7.5% through microscopy and 8.5% through SSU-PCR, suggesting a significant health concern.
- Genotyping revealed that the majority of samples belonged to assemblage A (54.5%) and B (45.5%), indicating that the transmission of giardiasis is primarily from human to human rather than from animals.
Article Synopsis
- A study collected 360 fecal samples from cattle, sheep, and humans at 10 farms in Ilam, Iran, to investigate Blastocystis infection prevalence.
- Results showed a 5.3% infection rate in animals (6% in cattle, 4.7% in sheep) and varied rates among humans with close (16.7%) versus non-close (3.3%) animal contact.
- Genetic analysis revealed four subtypes (ST1-ST3, ST10) in animals and multiple subtypes in humans, suggesting a potential transmission of these pathogens between animal and human populations.
is one of the common intestinal parasites causing diarrhea in humans and livestock, including pigs. Thus, a healthy livestock would result in a clean environment, which benefits humans. In the present study, the global molecular prevalence of infection was determined in pig populations, through systematic exploration of 4 international databases (MEDLINE/PubMed, Scopus, Web of Science, and Google Scholar) until March 4th, 2022.

The common intestinal protist, Blastocystis sp., is a highly frequent parasitic agent in human and animal fecal samples, globally. The current study evaluated the prevalence of this parasite and involved subtypes (STs) in examined pet dogs in Shiraz, southwestern Iran.

Methods: Systematic search was performed in PubMed, Scopus, Google Scholar, and Web of Science until 30th January 2022 and total estimates along with 95% confidence intervals (CIs) were computed using a random-effects model.
Results: Ultimately, the required data were extracted from 25 papers including 19 datasets for each animal.
Article Synopsis
- Blastocystis is a widespread intestinal protozoan that infects over 1 billion people globally, and its presence in pets, like dogs and cats, can pose health risks to humans due to zoonotic transmission.
- A systematic review of existing literature analyzed data from 49 studies covering 9,934 animals across multiple countries, revealing a 9.3% infection rate in cats and 7% in dogs.
- The study found greater subtype diversity in dogs than in cats, with ST3 being the most common subtype in dogs and ST4 the most common in cats, highlighting the need for awareness of potential health risks from pet ownership.

Article Synopsis
- The study reviews the prevalence and diversity of Sarcocystis parasites in cattle, focusing on their potential to infect humans.
- The analysis included 44 studies from 21 countries, finding a high overall prevalence of 62.7% in cattle, with 12 different Sarcocystis species identified.
- Key species included S. cruzi, S. hominis, and S. hirsuta, yet nearly half of the infections lacked molecular identification, highlighting the need for further research to understand the epidemiology of these zoonotic infections.
Article Synopsis
- The study investigated the presence and types of Giardia duodenalis, a protozoan parasite, in sheep and goats in Shiraz, Iran, focusing on its prevalence and potential for zoonotic transmission.
- Out of 200 fecal samples collected, the overall infection rate was 5.5%, with 7% in sheep and 4% in goats, and genetic analysis of positive cases revealed a predominance of assemblage E, with a notable detection of zoonotic assemblage A in sheep.
- The findings suggest a risk of zoonotic transmission in the region, indicating the need for further research to better understand the impact and distribution of Giardia in livestock.
Giardia duodenalis is one of the leading causes of diarrhea, mostly in underdeveloped nations of Africa and Asia. The present review provides insights into the prevalence, odds ratios (ORs) and associated risk factors of giardiasis in HIV/AIDS patients. Four major English databases (Web of Science, PubMed, Scopus, and Google Scholar) were excavated for relevant literature without time limitation until 20 November 2020.

Due to the zoonotic nature of its subtypes (STs), we aimed at global estimation of the prevalence, STs distribution, zoonotic potential, and associated risk factors of Blastocystis sp.

Methods: The present systematic review and meta-analysis was conducted to estimate the prevalence of G.
Blastocystosis is an interesting parasitosis, since the parasitic infection is still seriously neglected and a considerable zoonotic evidence is emerging. Blastocystis sp. infects the intestinal lumen of humans and a wide range of animals, while there is a lack of comprehensive information on Blastocystis epidemiology in cattle worldwide.

In this observational study, fecal samples were randomly collected from 800 dairy cattle, in 10 industrial dairy farms in Mashhad, Iran (from 2011 to 2015 years). The presence of Cryptosporidium oocysts was determined by modified cold Ziehl‑Neelsen's staining.
