Babesiosis is a significant tick-borne disease that impacts both domestic and wild animals, as well as humans, with its prevalence being particularly high in tropical and subtropical areas. Among small ruminants, Babesia ovis is a leading cause of babesiosis, especially in areas where Rhipicephalus bursa ticks are prevalent. The transmission of the...

Coenurus cerebralis consists of several protoscolices and it contains a transparent cyst wall. Domestic and wild canids constitute the predators, while a wide range of herbivores are the prey hosts. The study aims to evaluate the phylogenetic relationships and nucleotide diversity using partial sequences of the ND1 gene in different regions of Iran...

Dengue virus represents a global public health threat, being prevalent in tropical and subtropical regions, with an increasing geographical distribution and rising incidence worldwide. This mosquito-borne viral agent causes a wide range of clinical manifestations, from mild febrile illness to severe cases and potentially fatal outcomes due to hemor...

Hepatozoon canis is a type of single-celled organism is spread by ticks and commonly affects dogs. It is responsible for causing one of the most significant parasitic diseases in dogs, called Hepatozoonosis. It is considered one of the most common causes of canine vector-borne diseases because it is closely linked to Rhipicephalus sanguineus (the b...

A 6-year-old male domestic short-haired cat (Felis catus) was presented with weakness, anorexia, fever, icterus, a painful abdomen, ruffled hair and a tick infestation, and it had no prior surgery. Laboratory analysis revealed left-shifted neutrophils, thrombocytopenia, low albumin content and high serum bilirubin concentration as well as activitie...

The current study was designed to green synthesize silver nanoparticles (GRAgNPs) using Morus alba fruit extract and evaluate their nematicidal effects against strongyle nematodes compared to commercial silver nanoparticles (CAgNPs) in vitro. The nanoparticles were characterized by Ultraviolet-visual absorption spectrography, transmission electron...

Intestinal parasitic infections are one of the most important health problems. Although fresh vegetables are considered as a vital element of a healthy diet, they are a potential source of human intestinal parasitic infections during production, collection, transportation, preparation and consumption. The present study was carried out to determine...

Q fever is caused by Coxiella burnetii and is transmitted by more than 40 tick species. This study aimed to identify the tick species in goats of Meshkin-Shahr, Ardabil Province, Iran, and their role in the transmission of C.burnetii. A number of 365 goats were inspected for the infestation of hard ticks in a randomized sampling design, during a 1-...

Background: Bedbugs are blood feeding ectoparasites of humans and several domesticated animals. There are scarcity of information about the bed bugs population throughout Iran and only very limited and local studies are available. The aim of this study is to assess the phylogenetic relationships and nucleotide diversity using partial sequences of...

Abstract. Simaroubaceae is a monophyletic family in the order Sapindales with 22 genera and 109 species. Ailanthus altissima (Mill) Swingle, also known as the tree of heaven, is a highly invasive species, which systematically belongs to Simaroubaceae. Reproductive characteristics are essential for the deployment and maintenance of invasive species...

The present study was aimed to assess the bedbugs susceptibility to pyrethroid insecticides using molecular analysis. With the aid of pest control companies, adult bedbugs were collected from various places such as hotels, residential houses, and industrial buildings in seven cities highly crowded with domestic and foreign tourists in Iran from May...

Various species of Trypanosoma parasites are known to infect several wild and domestic animals worldwide. A 7-year-old Holstein cow from Baneh, Kurdistan province, was examined by a private veterinarian due to anorexia and depression. Physical examination revealed fever, enlarged subscapular lymph node, and pale mucosa. Blood samples were taken for...

A 4-year-old male one-humped camel (Camelus dromedarius) was referred to Veterinary Teaching Hospital of Urmia University, Iran in 2017 with anorexia, weakness, depression and pale mucosa. Decreased red blood cell count, packed cell volume and hemoglobin concentration were detected by complete blood cell count. In Giemsa-stained peripheral blood sm...

Drug resistance in helminth parasites has incurred several difficulties to livestock industry and ranked among the top public health concerns. Therefore, seeking for new agents to control parasites is an urgent strategy. In the recent years, metallic nanoparticles have been considerably evaluated for anthelmintic effects. The current research was c...

The present study was aimed to investigate oxidative stress, DNA damage, and histopatholog- ical alterations in hepatic tissues of splenectomized Wistar rats experimentally infected with Ba- besia bigemina. Rats were challenged with 5x106 infected erythrocytes. Babesia infection was con- firmed both with Giemsa's staining blood smears and nested-PC...

Ovine and caprine malignant theileriosis (OCMT), a critical condition in small ruminant production, causes lethal infections. In September 2016, a total number of 400 goats of Marghoz breed (the largest population of goat breed in Iran), in northwest of Iran, were examined for approximately 25 pre-partum abortions and 7 goats’ mortality for a perio...

This study was undertaken to assess the influence of an Anaplasma marginale infection on oxidative stress and antioxidant status, trace elements and cholinesterase as markers of the inflammatory process and biomarkers of oxidative imbalance. An infected group comprised of 35 crossbred Holstein cattle, about 2-3 years old, naturally infected with An...

Ectoparasites are considered as one of the most important pathogens threatening fish health and production. Due to importance of freshwater fish as a main source of food and income and also little accessible information regarding the serious infectious agents, especially ectoparasites, in fish, the present study was carried out to determine and ide...

Background: Toxoplasmosis is one of the most prevalent parasitic infections among humans and animals which caused by Toxoplasma gondii. This study was carried out to detection and identification of T. gondii in pregnant women population of Urmia, Iran. Methods: This cross-sectional study was done from August 2015 to March 2016. Totally, 620 pregnan...

Dictyocaulus arnfieldi is a lungworm commonly found in equids; however, relatively little is known about it. The aim of the present study was to establish the prevalence of equine lungworms in naturally-infected working and sporting horses, donkeys and mules in rural areas of Urmia, northwest Iran. The fecal samples were collected from 299 working...

In August 2015, the species Tabanus lunatus Fabricius, 1794 (Diptera: Tabanidae) was recorded for the first time from Iran. Two females were collected in Nazlo area near Urmia. Information on its morphology and distribution is given

A cross-sectional survey was performed on domestic pigeons (Columba liviadomestica) to evaluate the prevalence of Haemoproteus columbae and Trichomonas gallinae in West Azerbaijan Province, northwest of Iran between July 2015 and September 2016.
