Rodents are the primary reservoir hosts for zoonotic cutaneous leishmaniasis (ZCL) caused by . 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.

Background: The intriguing area of paleopathology merges the disciplines of archeology and biological studies. 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.

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.

  • - 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

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.

Background: We aimed to evaluate the rate of infection by endoparasites amongst rodents in the western regions of Iran to enhance the level of knowledge amongst health authorities in this entity.

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
  • 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.

Dung beetles as detritivores insects, naturally use feces of vertebrates as foods and reproduction beds. This leads to frequent contacts between dung beetles and parasitic helminths. The current study was carried out to assess infections of dung beetles with larval stages of helminths in rural areas of Taleqan County, Alborz Province, Iran.

Dioctophyme renale, is the largest of parasitic nematodes, which infects different species of fish-eating carnivores worldwide. The northern provinces of Iran (Guilan and Mazandaran) located in south of the Caspian Sea are suitable for parasitic infections due to the mild and humid climatic conditions. From separate surveys of road-killed canids in various parts of the Caspian Sea littoral area in Iran, 70 carcasses were collected along the roads of Guilan and Mazandaran from 2015 to 2017.
