IL-1β is produced by myeloid cells and acts as a critical mediator of host defense during infection and injury. We found that the intracellular protozoan parasite Toxoplasma gondii induced an early IL-1β response (within 4 h) in primary human peripheral blood monocytes isolated from healthy donors.
A 45-year-old man with AIDS was treated for a recurrence of cerebral toxoplasmosis with sulphadiazine, 4 g, and pyrimethamine, 75 mg, daily. Owing to a lack of appetite and dysphagia he drank rather little water during the first week of treatment. On the 13th day after starting the drugs he had
The obligate intracellular parasite Toxoplasma gondii is an important pathogen of humans and animals. Some of the devastating consequences of toxoplasmosis are in part due to the lysis of the host cell during parasite egress. The process of egress is poorly understood and since it is asynchronous in
Toxoplasma gondii is an obligate intracellular protozoan that causes toxoplasmosis. Previous studies have shown that the perturbation of mitochondrial metabolism in T. gondii results in growth deficiency in host cells and lack of virulence in animals. Members of this Letm1 protein family are inner
The risks of morbidity and mortality associated with transfusion are so great that no transfusion should be given until it is decided that it is absolutely necessary and then only with the utmost care. The unfavorable effects of transfusion reviewed are: hemolytic reaction; bacterial contamination;
Complete medical examinations were performed on 20 wild Decken's sifaka (Propithecus verreauxi deckeni) and 20 wild red-fronted brown lemurs (Eulemurfulvus rufus) from western Madagascar. Each animal received a complete physical examination, and weight, body temperature, heart rate, and respiratory
