Intestinal protozoan infection is a persisting public health problem affecting the populations of developing countries in the tropical and subtropical regions. The diagnosis of intestinal protozoa remains a challenge especially in developing countries due to a shortage of laboratory facilities, limited health funding, and the remoteness of communities. Despite still being widely used, conventional diagnoses using microscopy and staining methods pose important limitations, particularly due to their low sensitivities and specificities. The selection of diagnostic methods needs to be carefully considered based on the objective of examination, availability of resources, and the expected parasite to be found. In this review, we describe various immunodiagnosis and molecular diagnostic methods for intestinal protozoa infection, including their advantages, disadvantages, and suitability for different settings, with a focus on Entamoeba histolytica, Giardia duodenalis, and Cryptosporidium spp.
Toxoplasma gondii is one of the protozoan causes of chronic infection that allegedly causes obese (infectobesity). Some previous studies have showed that profilin Toxoplasma gondii has a role in inflammation by promoting interleukin-12 (IL - 12) which induce adipocyte dysfunction through the hyperplasia and hyperproliferation of adipocyte cells. Those processes lead to metabolic syndrome which increase adipocytes count through reducing insulin receptor’s sensitivity. On the other hand, Toxoplasma gondii, as an obligate intracellular parasite, can also damage the pancreatic beta cells. In response to inflammation, adipocytes produce Reactive Oxygen Species (ROS). To scavenge ROS antioxidants are required. Quercetin, an exogenous antioxidant, can be widely found in natural products that might be a promising candidate for development of antioxidant treatment interventions to prevent adipocytopathy. This research aims to explore the effects of quercetin towards Adipocytes Count stimulated from T. gondii profilin-exposed adipocytes. This research using visceral adipocyte rat that was cultured in Dulbecco’s Modified Eagle Medium (DMEM). After 70% confluency, adipocytes were exposed to 20 μΜ T. gondii profilin and treated with four doses of quercetin; 31.25, 62.5, 125, and 250 μΜ that incubated 48 hours. After incubation period, adipocytes were observed using inverted microscope and were captured in high power field magnification using camera. Adipocytes were counted from each captured photo and all groups were analyzed using Analysis of variance (ANOVA) test. The results showed that quercetin significantly reduced adipocyte cell count T. gondii profilin-exposed adipocytes compared to untreated cells (ANOVA p = 0,00). The effective dose to lower adipocyte cell count was 31,25 μΜ. This study implies that quercetin has a potent antioxidant that can prevent toxoplasmosis-mediated adipocytopathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
