ABSTRACT Aim: One of the main diagnostic problems of conventional polymerase chain reaction (PCR) is indiscrimination of low parasitic loads in soil samples. The aim of this study is to determine the genetic diversity and identification of Toxocara spp. from public areas soil inferred by loop-mediated isothermal amplification (LAMP) assay. MATERIALS AND METHODS A total of 180 soil samples wer...

BACKGROUND Accurate monitoring of health conditions and behaviours, and health service usage in the population, using an effective and economical method is important for planning and evaluation. This study examines the reliability of questions asked in a telephone survey by conducting a test/retest analysis of a range of questions covering demographic variables, health risk factors and self-rep...

Routine Trichinella meat inspection at the slaughterhouse detected one larva in a pooled batch of 100 pig samples. The larva was sent to the Norwegian Veterinary Institute (NVI) for species identification.Morphological examination revealed that the larva was not Trichinella spp. Molecular analysis was performed. PCR and sequencing of 5S/ITS identified the larva as Toxocara cati. A second round ...

Rodents are important intermediate and paratenic hosts for carnivore parasites, including the important zoonotic agents Toxoplasma, Echinococcus and Toxocara. Monitoring of such parasites in rodents can be used to detect increasing risks for human and veterinary public health. Rodents were trapped at four sites in Berlin, two near the city center, two at the periphery. PCRs were conducted to de...

Toxocaracati is one of the most important and widespread of the helminth zoonosis. In the present study, helminthosis due to Toxocaracati in 55 stray cats in Tehran was studied by necropsy. In addition, two different diagnostic methods, including serological and coprological tests, for infection with this parasite were compared. The dot-ELISA assay used Toxocaracati crude antigens to evaluate t...

this study aims at molecular identification of salmonella infantis isolated from backyard chickens and the detection of their antibiotic resistance genes. a total of 46 salmonella-suspected samples isolated from backyard chickens of northern iran were collected. serotyping was done by the traditional method and then confirmed by pcr. antimicrobial susceptibility of the isolates against 13 antim...
