Dioctophyma renale infection is found in a wide range of mammalian species, typically in temperate areas of the world. Here, we report for the first time, the parasitism of a domestic dog by D. renale in Hamedan, Iran, a mountainous cold region, lacking significant amounts of rainfall, high humidity and temperature. A 2.5 yr old male mixed breed dog was presented with a two months history of progressive hematuria and muscle weakness. Complete blood count and serum biochemistry were performed with results indicating impaired renal function...

We describe a case of visceral leishmaniasis (VL) due to Leishmania tropica in a 50-year-old Iranian man lived in a VL-endemic area in southwest of Iran. The patient presented with a 3-month history of fever and splenomegaly. Clinical signs and serological findings were suggestive of VL. Spleen biopsy was taken from the patient and intracellular forms of Leishmania amastigotes was seen in Giemsa stained smears. The patient was treated with pentavalent antimonial compound with complete resolution of his systemic signs and symptoms...

Cystoisospora belli, formerly Isospora belli, as an opportunistic infection agent, is seen in immunocompromised patients like HTLV-1. We describe here cystoisosporiasis in an HTLV1 Iranian female in Mashhad, northwestern Iran in 2012 who presented with a debilitating diarrheal illness and great weight loss. C. belli was detected in her stool by modified acid-fast staining and then by molecular detection. Serologic testing was negative for HIV but she showed positivity for HTLV-1 infection. Treatment with TMP/SMX led to improvement of her diarrhea but she died after one year due to malabsorption syndrome...

Malaria is a parasitic disease that is starting to be encountered in intensive care units (ICU) worldwide, owing to increasing globalisation. Severe malaria caused by Plasmodium falciparum, is characterised by cerebral malaria, acute renal failure, hypoglycaemia, severe anaemia, splenomegaly and alveolar oedema. We present the case of a 25-yr old male patient who presented to the Emergency Department of Uludag University in Bursa, Turkey in the winter of 2014 with complaints of fever for three days. His medical history revealed a 14-month stay in Tanzania...

Tachyzoite is the main form of Toxoplasma and continuously is maintained in cell culture or injected into the mice peritoneal cavity. This study was designed to evaluate the survival rate of RH strain of T. gondii tachyzoites in different cell free, nutrient and biological media at different temperatures. METHODS: This experimental study was performed at the Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran, in 2010...

BACKGROUND: The present study was formulated in order to determine polymorphism of dihydropteroate synthetase gene (dhps) of Plasmodium vivax (P. vivax) in Hormozgan Province, southern Iran and mutations at codons 382, 383, 512, 553, and 585 associated with resistance of P. vivax to sulfadoxine. METHOD: One-hundred eighteen isolates of P. vivax were prepared within 2007-2008 to determine dihydrofolate reductase-thymidylate synthase (dhfr-ts) gene. The isolates were determined in the study of genetic diversity of dihydropteroate synthetase gene (dhps) of P...

BACKGROUND: Myiasis is defined as the infestation of live human and vertebrate animals with dipterous larvae for a certain period. There are reports indicating that dogs are the most common species affected by myiasis. This study was conducted to identify myiasis-causing flies in owned and stray dogs in Mashhad (Northeastern Iran). METHODS: A total of 435 owned dogs and 800 stray dogs were examined for myiasis. Myiasis cases were cured and fly larvae were identified by microscopy using the relevant standard identification keys...

BACKGROUND: Equine piroplasmosis (EP) is the cause of persistent tick-borne infection with no symptoms, but the most important problem of EP is due to the persistent carrier state. Carrier animals to Babesia (Theileria) equi (Laveran 1901) and B. caballi (Nuttall, 1910) infestation could be identified by extremely sensitive PCR-based method. The purpose of this study was to identify the causative agents of equine piroplasmosis based on molecular and microscopic assays in equids from Kurdistan Province, Iran...

BACKGROUND: This study was performed to induce conversion of RH strain tachyzoites of Toxoplasma gondii to bradyzoites by pH changing of the culture medium. METHODS: HeLa cell monolayers were infected at a 1:1 tachyzoite to cell ratio. Four hours after infection, the culture medium was removed and replaced with culture medium and 5% FCS, adjusted to pH 8 with NaOH. The culture was maintained at 37 °C without CO2 until the end of the experiment. Cyst-like structures were collected and stained with periodic acid schiff (PAS) staining method...

BACKGROUND: To differentiate Sarcocystis macro-cyst-forming species in slaughtered sheep in Babol area, Mazandaran Province, sequence analysis of 18S rRNA gene was performed. METHODS: Overall, 150 slaughtered sheep were examined macroscopically in slaughterhouse, Babol and intra-abdominal and diaphragm muscles tissues infected with macro-cyst of Sarcocystis spp. were collected in 2013. One macro-cyst was isolated from the infected muscles of each sheep. The partial 18S rRNA gene was amplified by PCR and sequenced afterward...

BACKGROUND: The incidence of cutaneous leishmaniasis in the city of Mehran has risen sharply in recent years because the city borders Iraq, which has allowed entrance of different Leishmania strains. These strains have different shapes, periods of disease, and healing of lesions. The present study identified and determined cutaneous leishmaniasis species in this region. METHODS: This cross-sectional study was carried out by preparing slides from 92 patients with suspected cutaneous leishmaniasis lesions from Mehran during 2012-2013...

BACKGROUND: Fascioliasis, caused by Fasciola hepatica and F. gigantica, has medical and economic importance in the world. Molecular approaches comparing traditional methods using for identification and characterization of Fasciola spp. are precise and reliable. The aims of current study were molecular characterization of Fasciola spp. in West Azerbaijan Province, Iran and then comparative analysis of them using GenBank sequences. METHODS: A total number of 580 isolates were collected from different hosts in five cities of West Azerbaijan Province, in 2014 from 90 slaughtered cattle (n=50) and sheep (n=40)...

BACKGROUND: Metronidazole, a 5-nitroimidazole derivative, is the main antitrichomonal agent of choice for treatment of trichomoniasis. Since 1962, some cases of treatment failure with metronidazole have been reported and recently drug resistance is now on the rise in the world. This study was aimed to determine current susceptibility of Iranian isolates of Trichomonas vaginalis to metronidazole. METHODS: This study was performed on 50 T. vaginalis isolates collected from west and central areas of Iran...

BACKGROUND: Parasite proteases have important roles in cleavage of host proteins during the invasion of host tissues and participate in the parasite's evasion from the host's immune response. The aim of the present study was to estimate a metalloproteinase properties of Taenia solium metacestode (TsMP) during host-parasite interactions, and evaluate its potential as a serodiagnostic antigen for cysticercosis. METHODS: The cDNA coding for the mature catalytic domain of TsMP was cloned into pGEX-6P-1 expression vector...

BACKGROUND: Among the most important parasitic disease, causing diarrhea, Giardia lamblia is noteworthy. Nowadays detection methods for these parasites include parasitological methods such as microscopic examination. The sensitivity of these methods relies on the expertise and experience of examiners. In contrast, molecular methods such as PCR are less dependent on the expertise of the examiner. Here we developed a PCR for the detection of G. lamblia genome in stool samples in comparison with microscopy, which is the gold standard...

BACKGROUND: Leishmaniasis is an obligate intercellular protozoon that affects animals and human. It has zoonosis and/or anthroponosis transmission. Human and veterinary medicine, environmental science and wildlife conservation specialists have many commonalities in case of visceral leishmaniasis. Still the above disciplines respond against leishmaniasis in a separate way. The aim of this review is to indicate inter- and intra- sectoral collaboration for planning future control strategies...
