چکیده

We investigated the activity of roxithromycin (RU 965) and gamma interferon alone and in combination in a murine model of toxoplasmic encephalitis. Roxithromycin at a dosage of 35 or 50 mg per mouse per day decreased mortality. Gamma interferon alone significantly prolonged time to death. When combined, the two agents were remarkably synergistic.

A serological and parasitological study of Toxoplasma gondii infection in stray cats of Mashhad, Khorasan Razavi province, Iran

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.

Study of resistance to Toxoplasmosis using Tachizoites surface antigens of Toxoplasma gondii in vivo

Taoxoplasma gondii is an important food-borne parasite transmitted primarily from animals to humans through meat consumption, mainly pork and lamb, as well as through oocysts shed by cats. Infection in humans can cause severe fetal malformations, ocular complications or encephalitis. Toxoplasmosis infection during pregnancy, especially in sheep, often results in abortion, representing considera...

Immunogenicity of Gamma-Irradiated Toxoplasma gondii Tachyzoites in Mice

The Immunogenicity of γ-irradiated tachyzoites of a highly virulent strain of Toxoplasma gondii (RH strain) was investigated. Immunized mice survived challenge infection and displayed increased interferon gamma (INF-γ ) production. On the other hand, nonimmunized controls died after 10 days and displayed a significantly decreased lymphoproliferative response to Concanavalin A (Con A). No tachyz...

CD40 restrains in vivo growth of Toxoplasma gondii independently of gamma interferon.

CD40-CD154 interaction is pivotal for resistance against numerous pathogens. However, it is not known if this pathway can also enhance in vivo resistance in gamma interferon (IFN-gamma)-deficient hosts. This is an important question because patients and mice with defects in type 1 cytokine response can control a variety of pathogens. While blockade of endogenous CD154 resulted in a remarkable i...

Effect of roxithromycin on acute toxoplasmosis in mice.

Roxithromycin effectively treated acute peritoneal murine toxoplasmosis. After five doses, starting 24 h after challenge, the 100 and 50% survival doses were 540 and 336 mg/kg per day, respectively. After 14 doses, starting 3 h after challenge, the 50% survival dose was 360 mg/kg per day. Toxoplasma gondii was recovered from the brain in 59 and 28% of surviving mice treated with 5 and 14 doses,...
