Toxoplasma gondii is one of the most common protozoan parasites with widespread distribution globally. It is the causative agent of Toxoplasma infection, which is prevalent in human and other warm-blooded vertebrates. While T. gondii infection in healthy people is usually asymptomatic, it can lead to serious pathological effects in congenital cases and(More)
BACKGROUND Toxoplasmosis is considered as one of the most common infectious diseases caused by the protozoan parasite Toxoplasma gondii. Tachyzoite is the main form of Toxoplasma and continuously is maintained in cell culture or injected into the mice peritoneal cavity. This study was designed to evaluate the survival rate of RH strain of T. gondii(More)
OBJECTIVE To analyze and review the overall seroprevalence rate of Toxoplasma gondii (T. gondii) infection in cattle from Iran. METHODS In the current study, data collection (published and unpublished papers, abstracts of national scientific congresses and dissertations) using particular terms was carried out systematically on the following electronic(More)
Many recent studies have been conducted to evaluate protective immunity mediated by DNA vaccines against toxoplasmosis. Cocktail DNA vaccines showed better immune responses compared to single vaccines. The objective of the current study was to evaluate the protective efficacy of rhomboid 4 (ROM4) and cocktail DNA vaccines (ROM4 + GRA14) of the Toxoplasma(More)
The objective of the current study was to systematically review papers discussing the efficacy of medicinal herbs against Toxoplasma gondii. Data were systematically collected from published papers about the efficacy of herbs used against T. gondii globally from 1988 to 2015, from PubMed, Google Scholar, ISI Web of Science, EBSCO, Science Direct, and(More)
Although toxoplasmosis in immunocompetent individuals is generally asymptomatic, in immunocompromised patients (HIV/AIDS, cancer, and transplant patients), it can lead to serious pathological effects. This study included a systematic review and meta-analysis to comprehensively assess the seroprevalence rate of Toxoplasma infection in immunocompromised(More)
Excretory-secretory antigens (ESAs) of Toxoplasma gondii are one of the candidates for immunization against toxoplasmosis. For evaluation of immunization, we determined the kinetics of the distribution of Toxoplasma and parasite load in different tissues of mice immunized by ESAs. In this experimental study, 36 mice in case (n=18) and control (n=18) groups(More)
Toxoplasmosis, responsible for ocular impairment, is caused by Toxoplasma gondii. We investigated the effect of Toxoplasma excretory-secretory antigens (ESA) on parasite load and distribution in the eye tissue of a murine model. Case and control groups were immunized with ESA and PBS, respectively. Two weeks after the second immunization, the mice were(More)
Parasitic infections are a serious public health problem because they cause anemia, growth retardation, aggression, weight loss, and other physical and mental health problems, especially in children. Numerous studies have been performed on intestinal parasitic infections in Iranian preschool and school children. However, no study has gathered and analyzed(More)
BACKGROUND Toxoplasmosis is a public health problem worldwide. This complication principally affects immunodeficient patients and pregnant women. Toxoplasma gondii is an opportunistic parasite, causing severe illness among and death of high-risk individuals and treatment is becoming increasingly difficult owing to side effects and low efficacies of drugs.(More)
