Prevalence of Dirofilaria immitis and Dirofilaria repens in outdoor dogs in Tehran Province, Iran

AbstractDirofilaria immitis andDirofilaria repens are the most common species of filarial nematodes described in dogs, which are endemic in Iran. The diagnosis of canine dirofilariosis is usually based upon the microscopical detection and identification of circulating microfilariae together with ELISA detection of serum circulating heartworm antigens or antibodies. The identification of the parasite species using the traditional approaches sometimes can lead to misdiagnosis. As a zoonotic disease, it is important to know the prevalence ofDirofilaria in Tehran that is the most crowded province with many outdoor and stray dogs in suburb areas. In this paper, we used modified Knott ’s test and a single-step multiplex PCR to detect and differentiateD. immitis andD. repens. Blood samples were collected from 311 outdoor dogs from March to August 2017. A total of 28.35% of dogs were positive by PCR in which 2.3% and 26% wereD. immitis andD. repens, respectively. The highest incidence of infection was between 1 and 2.5  years old age. No sex predilection was observed. In the west of Tehran, prevalence ofD. repens was statistically more than the other areas (p

ConclusionHydatid disease should be thought when patients present with mass lesion in any part of the body especially in endemic areas. The most important step in the diagnosis is to exclude the presence of other cysts in other parts of the body.

There are several methods to diagnose this disease, which have different principles, sensitivity, and specificity. Among them, the serological techniques using T. evansi as antigen are powerful tools for its epidemiological surveillance. However, they are poorly used due to inefficient in ...

ConclusionThis meta-analysis provides a comprehensive analysis of schistosome infection in sentinel mice across China. The estimates largely mirror the ongoing trends of transmission in terms of periods and regions. Infections were most likely to occur in April, July and October. In areas where no infected snails were reported infections in sentinel mice were still observed. Due to the presence of snails and infected wildlife, detection of schistosomes in waters using such a highly sensitive method as the deployment of sentinel mice, remains of importance in schistosomiasis monitoring. We would suggest the current criteria...

AbstractEchinococcus granulosus is the etiological agent of cystic echinococcosis (CE), also commonly called hydatidosis. This is a zoonotic infection endemic worldwide, including the Mediterranean basin and Morocco. The genetic variability ofEchinococcus granulosus is known to influence development of parasitic cysts in different intermediate hosts, and therefore the epidemiology of infection. Molecular studies have identified nine genotypes ofEchinococcus granulosus, eight of them affect humans, grouped today in four distinct species. In Morocco, molecular studies on CE cysts from animals showed the presence, for the lar...

Conclusions/SignificanceResults of this study indicate that ‘The Vicious Worm’ may be an effective tool for both short- and long-termT.solium education of rural primary school students in Zambia. Inclusion of educational workshops using ‘The Vicious Worm’ could be recommended for integrated cysticercosis control/elimination programs in sub-Saharan Africa, particularly if the content is simplified to focus on the key messages for prevention of disease transmission.
