is a parasite prevalent in the temperate regions of the vast Palearctic realm, including Iran. In this study, we investigated infection in road-killed animals and carcasses in northern and northeastern Iran by artificial digestion. We assessed species identification and intraspecific genetic diversity using the markers 5S ribosomal DNA intergenic spacer (5S rDNA), internal transcribed spacer I (ITS1), and cytochrome oxidase subunit I ().

Knowing reservoir hosts is crucial for leishmaniasis surveillance and control programs in endemic areas. In this study, we examined an archived spleen of obtained during a pest control program in 2000 in Tehran, the capital of Iran.

Using this line of research, it is possible to identify diseases that have left skeletal traces in the past. In addition, diseases such as various anemia that occur in childhood, when bone tissue is soft and retains evidence, can be identified in ancient bones.

- The study investigated the immunomodulatory effects of recombinant and excretory-secretory proteins from the helminth Fasciola hepatica on induced colitis in Balb/c mice.
- The treatment with recombinant Peroxiredoxin and Cathepsin L1 led to significantly lower inflammatory scores and reduced secretion of the pro-inflammatory cytokine IFN-γ compared to control groups.
- The findings suggest that these proteins may help modulate the immune response by decreasing inflammation and increasing levels of anti-inflammatory cytokines like IL-10.
Article Synopsis
- The study investigates coccidian oocysts found in a horse dung sample (coprolite) from the Chehrabad Salt Mine in Iran, dating back to the Sassanid Empire (2nd-6th century CE).
- Researchers identified seven oocysts of Eimeria leuckarti, marking the first documented instance of ancient coccidian oocysts from equids.
- The findings enhance our understanding of ancient parasite biodiversity in Iran, especially along the Silk Road, while emphasizing the need for further research to establish the host origins of the coprolites and discover more parasite species.
Purpose: Fascioliasis is caused by Fasciola hepatica of almost worldwide distribution and F. gigantica in wide regions of Asia and Africa. Their adult stage develops in the biliary canals and gallbladder.

- - Acute appendicitis is a common cause for emergency abdominal surgery, and this study explores the potential link between it and Enterobius vermicularis, a type of pinworm, using archived tissue samples from appendectomies in Iran.
- - The researchers examined 17 old-archived appendectomy samples and found tissue changes in 76.4% of cases, with successful amplification of the cox1 gene in 70.6% of samples using a nested PCR technique.
- - Phylogenetic analysis revealed 59 different haplotypes of E. vermicularis, indicating genetic diversity; they identified five haplotypes that are part of type B. The findings suggest that E. vermicularis
Background: Dermatoparasitic infestations due to the mites spp. and are prevalent dermatological disorders worldwide.
Methods: Referral patients from the Departments of Dermatology, Infectious Diseases, and from the psychologists, in some cases, to the laboratory of Medical Helminthology, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran were examined and documented for demodicosis and scabies from March 2009 to December 2020.
Article Synopsis
- * This research marks the oldest documented case of human giant kidney worm infection in the Middle East, occurring in an area where such infections are still reported today.
- * The cemetery at Kiasar offered a rare chance to explore the historical prevalence of human and animal parasites during the Parthian Empire, suggesting that this parasite was less common in the past based on limited historical records.
Of the eleven species of shrews described in Iran, the Etruscan shrew (Suncus etruscus), the smallest known extant mammal by mass, is recorded in northern and southern provinces. During rodent control programs, a female S. etruscus was trapped and found naturally infected with a trematode which was morphologically identified as Brachylaima sp.

Methods: This study was conducted in the west and southwest of Kurdistan Province, including the cities of Sanandaj, Marivan, and Sarvabad. The field mission of this work was performed in three seasons' spring, summer, and autumn.

Article Synopsis
- A fecal pellet from an ancient salt mine in Chehrabad, Iran, was examined for parasites due to the mine's ability to preserve organic materials.
- The pellet was rehydrated and analyzed under a microscope, revealing two first-stage larval nematodes belonging to the genus Muellerius, but no eggs or oocysts were found.
- The decision was made not to grind the larvae for DNA analysis because they were well-preserved, and their discovery contributes to paleoparasitological studies from the Sasanian Empire period.
Background: Two calcified objects recovered from an adolescent in a burial site in Amiens, France, have been previously identified as hydatid cysts using thin-section petrography. The importance of ancient hydatidosis besides the value of these unique archeological excavated materials encouraged the authors to look at this attractive subject more interdisciplinary by implementing medical radiology.
Methods: In the current experiment, which has been carried out in the Radiology Department, Tehran Heart Center (THC), Tehran, Iran, the conventional and dual-energy dual-source Tomography, X-Ray Computed-scan was used in studying the remaining structures of the two calcified masses.
Article Synopsis
- The study compared two diagnostic methods, semi-nested PCR and indirect ELISA, for detecting human fasciolosis using 70 serum samples from suspected patients in Iran.
- Results showed that semi-nested PCR had a higher agreement rate (98.4%) compared to indirect ELISA (94.46%), with no false positives from other parasitic infections.
- The findings suggest that semi-nested PCR is a reliable confirmatory method and can be used to monitor patient treatment effectively.
Article Synopsis
- Palaeoparasitology studies ancient parasitic infections in humans and animals through the analysis of biological remains, primarily palaeo faeces, known as coprolites.
- * These coprolites offer insights into ancient diseases, diets, and population movements, while modern techniques like ancient DNA detection enhance traditional microscopy methods.
- * Research conducted at the Chehrabad salt mine revealed the presence of helminths, including the recently introduced Taenia asiatica, utilizing advanced methods like Next Generation Sequencing to uncover historical pathogenic agents.
Cestodes are important parasites that can affect the health of humans and wildlife. Among these, the genus is an important endoparasite of Passeriform birds while poorly studied in Iran. During a parasitological field survey in central parts of Iran in 2018, thirty-two cestode, as an obstructive intertwined mass, recovered from the intestine of a recently dead (great tit).

- Dioctophyme renale is a parasitic nematode found in fish-eating carnivores, particularly in the humid and mild climate of northern Iran's Caspian Sea provinces.
- A study from 2015 to 2017 involved collecting 70 road-killed canids, revealing that Dioctophyme renale was present in eight cases, primarily affecting the right kidneys or found in the abdominal cavity.
- Due to the high prevalence of this parasite, there is concern about its potential transmission to humans, especially in a region popular with tourists, prompting the need for further research into its infection rates through DNA analysis.
Article Synopsis
- The research aimed to find a reliable non-molecular method for identifying parasitic worms, focusing on adult fasciolids collected from slaughterhouses in Iran.
- Historical morphological techniques and modern molecular methods were used to examine these worms, revealing distinct types of tegumental spines for species identification.
- The study highlights the importance of hidden morphological features and advocates for the use of advanced imaging technology to enhance the accuracy of taxonomic measurements in helminthology.
