The Persian squirrel (Scuirus anomalus) has a long furry tail, which is longer than half of the body, and lives in the Zagros forest. It is distributed in the west and northeast of Asia. In the summer 2011 a Persian squirrel with signs of hair loss and itch in head and tail was referred to the veterinary clinic. There were arthropods in the lesion in the first survey. Many of these parasites were collected and were sent to Parasitology Laboratory of Science and Research University in Tehran. Samples were processed and were identified according to lices diagnostic keys using a light microscope. Lice that were sent to the national parasitology museum were identified as Polyplax sp. too.

In July 2012 a male Common Buzzard (Bute obuteo) from the Department of Environment of East Azerbaijan was sent to the Parasitology Laboratory at the School of Specialized Sciences of Veterinary Medicine, Science and Research Unit, Tehran Islamic Azad University. Gastrointestinal parasites were isolated and sent to the Iranian National Parasitology Museum in order to specify the diagnosis. It was determined that the bird was infected with the acanthocephalan Centrorhynchu saluconis. This is the fi rst report of Common Buzzard infestation with this parasite in Iran.

Cystic echinococcosis (CE) is one of the most prevalent zoonotic diseases in some countries in the world. Cystic echinococcosis is considered a neglected disease. This disease increases economic damage via medical costs and loss of human and livestock productivity. The aim of the current study gains a better understanding of the prevalence of CE in sheep. Totally 250 sheep sera were collected. 25 serum samples from newborn lambs were used as negative, and 25 others were obtained from slaughterhouses as positive to infection with CE and 200 unknown sera. Antigen B Isolated from hydatid cysts fluid was used for designing ELISA methods. The first Method used anti-Sheep conjugate (SIGMA, at 1:3000 dilution). According to the results, the seroprevalence of CE in East Azerbaijan of Iran was 5.5% and sensitivity and specificity for the diagnosis of hydatidosis in sheep by AgB-ELISA methods was 92%. Using Antigen B in ELISA design for hydatidosis diagnosis has attracted researchers in recent years. During this study, an Iranian native B antigen was used to design the specific detection of hydatidosis in sheep using a specific ELISA technique. The results have shown that using Antigen B in ELISA design is so valuable.

In Iran, wild boar is distributed throughout the country, except the Central Desert. One of the important habitats of this animal is the northern mountainous area. They may pass infected faeces in these areas, which can lead to zoonotic disease, though information about parasitic infections in wild boar is rare in Iran and further study is necessary. In February 2019, a wild boar carcass was submitted to the Veterinary Parasitology Department of the Science and Research University of Tehran by the Department of Environment of Mazandaran province in order to study its parasitic infections. Faeces and the gastrointestinal tract were separated and their contents were tested using two flotation methods (Willis and Clayton-Lane), and the samples were referred to the Parasitology Laboratory of Urmia University for further study. The sample was infected with Eimeria protozoa; Eimeria porci and Eimeria neodebliecki were diagnosed based on the size and morphology factors of the isolated oocysts. This is the first report of wild boar infection by Eimeria sp. protozoa in Iran.

Hydatidosis is one of the most important zoonotic diseases, and it is transmitted via dogs to intermediate hosts such as humans and domestic animals including sheep and cattle. Epidemiological studies and genetic investigations indicate that the sheep strain is the most common species causing hydatid cysts in humans. The prevalence and incidence of this disease are increasing. According to surveys, economic losses due to this parasite in intermediate hosts are significant. In this survey, 25 serum samples were obtained from newborn lambs as negative control and obtained 25 serum samples from infected sheep to hydatidosis as the positive control. Antigen B isolated from hydatid cysts fluid was used for designing ELISA methods. Using Antigen B in ELISA design for hydatidosis diagnosis has attracted researchers in recent years. During this study, an Iranian native B antigen was used to design the specific detection of hydatidosis in sheep using a specific ELISA technique. The first method used the anti-Sheep conjugate (SIGMA, at 1:3000 dilution), and the second method used gold nanoparticles in combination with anti-sheep conjugate. According to the results, sensitivity and specificity in sheep of the AgB-ELISA method were both 92% and for the Nano-ELISA with Gold Nanoparticles 100% and 96%, respectively. Moreover, results indicated that using Antigen B in ELISA design is valuable but specificity and sensitivity will increase significantly, especially in lower titer, when gold nanoparticles with anti-sheep conjugate are used.
