Loop-mediated isothermal amplification as a reliable assay for Toxocara canis infection in pet dogs

Loop-mediated isothermal amplification as a reliable assay for Toxocara canis infection in pet dogs Keeping of infected dogs as pet results in the potential transmission risk factors for shedding helminthic infections such as toxocariasis. Lack of accurate identification of Toxocara canis eggs in non-dewormed infected pet dogs remains a diagnostic concern among researchers. In this study, dog owners were asked to fill up a questionnaire regarding their pets and their attitude towards the deworming regimen. One hundred faecal samples were collected from pet dogs (Northwest Iran) and were subsequently identified by the ZnSo4 flotation technique, PCR and loop-mediated isothermal amplification (LAMP) assays. The DNA of the recovered T. canis eggs was then extracted and amplified by LAMP and PCR. Furthermore, ITS2 amplicons were sequenced for appraisal of the phylogenetic analysis. Nine, 5 and 11% of T. canis infections were identified by microscopy, PCR and LAMP, respectively. It was detected that LAMP was 10 times (10−10to 10−13 g/μl) more sensitive than PCR (10−10to 10−12 g/μl). The kappa value between LAMP and PCR indicated a faint concurrence (0.463). The kappa coefficient between LAMP and flotation technique indicated a strong agreement (0.667). The highest infection rate (n = 11) was detected in non-dewormed pet dogs, particularly those less than 3 months old (P < 0.05). None of the infected dogs had a history of walking and kennelled behaviours in public places. The LAMP assay can address as a simple, rapid and highly sensitive technique for detecting low burden of T. canis eggs in infected pet dogs. It was proposed that the dog holder’s awareness is insufficient to implement regular deworming schedules. Additionally, regional policymakers should broadly revise anthelmintic treatment guidelines. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Parasitology Research Springer Journals
