The aim of the present study was to determine seroprevalence of Toxoplasma gondii infectionin stray cats and correlation with oocyst shedding and IFN-γ concentration. From April to August 2016, one hundred fifty-nine stray cats were captured from various localities in Mashhad area. The blood and fecal samples were collected from each cat. The serum samples were examined to detect antib...

Neospora caninum é um protozoário de grande importância, responsável por causar neuropatias em canídeos e abortamento bovinos. A prevalência anticorpos anti-N. consideravelmente diferente entre países as regiões geográficas do Brasil, apresentando uma ampla variação soropositividade hospedeiros definitivos intermediários. Neste sentido, o estudo objetivou avaliar a frequência cães município Ser...

Infection by the protozoan parasite Toxoplasma gondii, is widespread in humans and many other warm-blooded animals. More than half billion of world human population has serum antibodies to T. gondii and Sheep and goats are more widely infected with T. gondii. T. gondii infection can be diagnosed indirectly with serological methods and directly by pol...

Introduction: Toxoplasmosis is a widely prevalent zoonotic disease, caused by T. gondii. Chickens, consumed widely in many countries, are considered as one of the most important hosts in the epidemiology of T. gondii infection because they could be a main source of infection for both cats and humans. There was no information regarding T. gondii infection in chickens in this area, therefore, thi...

Neospora caninum (N. caninum) and Toxoplasma gondii (T. gondii) are both obligate intracellular protozoan parasites, which have gained considerable attention because of their role in bovine abortion. This study aimed to detect anti-N. caninum and -T. gondii in bulk milk of dairy cattle, Mashhad, Iran. The bulk milk samples were collected from July 2014 to June 2015 and analyzed for anti-N. cani...

Introduction : Toxoplasmosis, caused by Toxoplasma gondii, is a protozoan parasitic infection distributed worldwide. Early infection by this protozoa can lead to abortion and congenital toxoplasmosis in pregnant women. This study was conducted to determine the seroprevalence of T. gondii infection among pregnant women referring to Shahid Akbar Abadi Hospital, Tehran, Iran during 2010-2013. Meth...

Toxoplasma gondii is an apicomplexan parasite that infects human and almost all warm-blooded animals. The life cycle of the parasite includes an asexual reproduction in intermediate hosts (Mammals and birds) and a sexual reproduction in definitive hosts (Felidae). Cats are both the intermediate and the definitive host for T. gondii. The aim of this study was to investigate anti-T. gondii antibo...

Cats are important in the epidemiology of Toxoplasma gondii because they are the only hosts that can excrete environmentally resistant oocysts. The prevalence of T. gondii was determined in 58 domestic cats from 51 homes from Santa Isabel do Ivai, Parana State, Brazil where a water-associated outbreak of acute toxoplasmosis had occurred in humans. Antibodies to T. gondii were found with the mod...

Breast cancer is the most prevalent malignancy in women throughout the world. Similar to other cancers, a strong relationship between breast cancer and environmental factors such as infectious agents has been reported. Toxoplasma gondii is a protozoan parasite which may play a role in cancer induction. The present study aimed to investigate a possible association between a history of T. gondii ...

Background Toxoplasma gondii (T. gondii) can disseminate to brain in infected hosts. Little is known about the magnitude of the association between this infection and headache. Therefore, we sought to determine the association of T. gondii seropositivity and headache in patients attending neurological consultations in a public hospital in Durango City, Mexico. Methods Through an age- and gend...
