In this study, we aimed to determine the prevalence and risk factors associated to Toxoplasma gondii infection in sheep from northeastern Brazil. A total of 932 ovine serum samples from 54 properties in 19 municipalities of the state of Sergipe were collected and assayed using indirect fluorescent antibody test. The assay used antibodies against Toxoplasma gondii (IFAT-IgG) with a cutoff point ...

Toxoplasma gondii is one of the most prevalent intracellular parasite found in human population. Usually the organism causes mild orasymptomatic infection. However, disease occurs in immunocompromised individuals or when the parasitic load saturates the body’s immune defences. Serological studies establish the frequency of antibodies within a population. The rates of infection are 293%, USA l0-...

Over the years, there have been scattered, sporadic (and usually small) studies on Toxoplasma gondii seroprevalence in the African continent, and this is unfortunate. The current human immunodeficiency virus (HIV) epidemic on the continent, increasing levels of other immunosuppressive infections (such as tuberculosis), poor sanitation and hygiene practices, inadequate veterinary services, and h...

To estimate the prevalence of congenital toxoplasmosis, Chagas disease, cytomegalovirus, and rubella, blood samples on dried blood spot (DBS) from neonates (day 3-20 of life) were screened for immunoglobulin (Ig) M against Toxoplasma gondii, cytomegalovirus, rubella virus, and IgG against Trypanosoma cruzi by methods used for serum and adapted for use with DBS. Positive samples were further ana...

by DANAYA AMINA BETHEA (Under the Direction of Ynes R. Ortega) ABSTRACT Toxoplasma gondii is an intracellular obligate protozoan parasite that causes toxoplasmosis in humans. This study aimed to detect and genotype T. gondii in fresh produce. Six PCR assays using various Toxoplasma gene targets were examined for their suitability in vegetable matrices. The SAG2 PCR was selected for this study. ...

Cats are essential in the life cycle of Toxoplasma gondii because they are the only hosts that can excrete the environmentally resistant oocysts in nature. Nothing is known of the prevalence of Toxoplasma gondii in cats from Sri Lanka. Serum samples from 86 cats from Colombo, Sri Lanka, were tested for antibodies to T. gondii using the modified agglutination test; antibodies were found in 26 (3...

OBJECTIVE To determine the change of incidence and prevalence of neurological disorders caused by the human immunodeficiency virus (HIV) and opportunistic infections in HIV positive patients under treatment since the introduction of highly active antiretroviral therapy (HAART). METHODS The data of all HIV infected patients were retrospectively analysed, who were examined in the HIV outpatient...

Cerebral toxoplasmosis is one of the frequent opportunistic infections central nervous system Human Immunodeficiency Virus (HIV) patients in presence Toxoplasma Gondii infection. In Indonesia, incidence HIV with cerebral 45%. This study was done to determine demographic, clinical, and laboratory characteristics at Haji Adam Malik Hospital, Medan, based on medical record data 2022. The total sam...
