The over-use of anti-parasitic compounds as a method of control has led to insufficient effectiveness and widespread drug resistance worldwide. The aim of this study was to investigate the efficacy of albendazole and levamisole as anti-parasitic agents in a lung worm control program in goat flocks. During 2021 and 2022, a total of 110 goats (age of four months and above) were randomly selected from 11 herds in the north-western region of Iran including Saanen breed (both sexes of the same age).

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 microscopy, and X-ray diffraction. Next, uptake of AgNPs by the first stage larvae (L), egg hatch inhibition (EHI) and the motility of infectious larvae (L3s), and the ultrastructural analysis of the eggs and worms were conducted.

This study aimed to evaluate the efficacy of fenbendazole and ivermectin on strongyles and Parascaris sp. infecting adult riding horses in three regions with different climates. During 2021 and 2022 fecal specimens were randomly collected from 483 horses older than three years in 31 equestrian clubs in Hamedan (n = 217), Yazd (n = 146) and Tabriz cities (n = 120).

Article Synopsis
  • Pyrethroid insecticides affect voltage-gated sodium channels (VGSCs) in insects, and specific mutations in these channels (M815I, T917I, L920F) are linked to resistance in lice globally.
  • This study focused on detecting resistant alleles in goat biting lice collected from five provinces in Iran by analyzing mutations in the VGSC gene.
  • Findings revealed multiple mutations associated with pyrethroid resistance in all samples, suggesting that overuse of these insecticides has contributed to this resistance, which can inform pest control strategies.

is a zoonotic protozoan infecting various vertebrates such as humans and domestic animals. The aim of this study was to determine the frequency and genotypes of using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in dogs of Urmia, Iran. Overall, 246 stool specimens were collected from 100 pet, 49 stray, and 97 shelter dogs in the Urmia, Iran.

Resistance to the knockdown effect of pyrethroid insecticides occurs due to mutations at target sites of pyrethroids, meaning the voltage-gated sodium channels gene (VGSC) in the membrane of the neurons. In fleas, this mutation occurs at two sites in the sodium channel in neurons: one is the replacement of leucine with phenylalanine (L1014F) and the other is the replacement of threonine with valine (T929V). In this study, 81 and 47 fleas were collected from five provinces in the west and northwest of Iran.

A 2-year-old female Shih Tzu dog was submitted with the history of anorexia and depression for one week and no prior surgery. Fever and pale mucosa were noticed in physical examination. Microscopic examination of the Giemsa-stained blood smear disclosed large form of  and single to four pear-shaped merozoites within erythrocytes (RBCs).

is a parasite that acts as a canker-causing agent and leads to significant loss and mortality, especially in young birds. Metronidazole is the approved drug used for the treatment of trichomoniasis. A non-chemical alternativess such as medical plant extracts are also used to treat this disease due to drug resistance.

Naturally occurring Babesia bigemina infection in cattle is associated with changes in the status of oxidative stress, trace elements, sialic acid, and cholinesterase activity in blood. However, to date there is no description of hepatic damage in the infected animals. More importantly, the majority of the above-mentioned causative factors are synthesized or stored in the liver.

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 cytochrome oxidase I gene (COI) among the populations of tropical bed bugs inhabiting Iran.

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 2016 to August 2017 Bedbugs were colonized in the laboratory to evaluate their resistance to pyrethroid using insecticide resistance bioassay. Genomic DNA was extracted from susceptible and resistant bedbugs.
