Accurate sorting of proteins to the three types of parasite-specific secretory organelles namely rhoptry, microneme and dense granule in Toxoplasma gondii is crucial for successful host cell invasion by this obligate intracellular parasite. Despite its tiny body architecture and limited trafficking machinery, T. gondii relies heavily on transport of vesicles containing proteins, lipids and impo...
Erythrocyte invasion by the merozoite is an obligatory stage in Plasmodium parasite infection and essential to malaria disease progression. Attempts to study this process have been hindered by the poor invasion synchrony of merozoites from the only in vitro culture-adapted human malaria parasite, Plasmodium falciparum. Using fluorescence, three-dimensional structured illumination, and immunoele...
Invasion of host cells by apicomplexan parasites is initiated when specialized secretory organelles called micronemes discharge protein complexes onto the parasite surface in response to a rise in parasite intracellular calcium levels. The microneme proteins establish interactions with host cell receptors, engaging the parasite with the host cell surface, and signal for the immediate exocytosis...
Toxoplasma gondii, an opportunistic protozoan parasite, infects almost all warm-blooded animals. In this study, we examined the sequence variation in rhoptry protein 20 (ROP20) genes among 18 T. gondii isolates collected from different hosts and geographical regions. Full length ROP20 genes were amplified and sequenced. The results showed that the genes were 1659 bp in length and contained only...
IntroductionToxoplasmosis is a well-known zoonotic disease caused by Toxoplasma gondii. The main causes of the range from eating undercooked or contaminated meat and shellfish to cleaning litter trays into which cats that excreted toxoplasma via faeces. This pathogen can live for very long time, possibly lifetime, within bodies humans other animals.Aims objectivesThis study aimed predict analys...
The apicomplexan Toxoplasma gondii (Nicolle et Manceaux, 1908) secretes a group of serine/threonine kinases from rhoptries, which play vital roles in boosting intracellular infection. rhoptry organelle protein 17 (ROP17) is one these important kinase proteins. Nevertheless, its function remains unclear. Here, we showed that ROP17 induced autophagy vitro and vivo. small intestine tissues T. tach...
This study was aimed to detect anti-Toxoplasma gondii antibodies in cats infected with Rh strain of T. gondii by using an immunoblotting method. For this, cats were experimentally infected using tachyzoites harvested from Vero cell cultures. Tachyzoites were then lysed and transferred to polyacrylamide gels followed by blotting to PVDF membranes. An immunoblotting was performed using these mem...
