Resistance towards metronidazole in Blastocystis sp.: A pathogenic consequence

Granular Formation during Apoptosis in Blastocystis sp. Exposed to Metronidazole (MTZ)

The role and function of the granular life cycle stage in Blastocystis sp, remains uncertain despite suggestions being made that the granules are metabolic, reproductive and lipid in nature. This present study aims to understand granular formation by triggering apoptosis in Blastocystis sp. by treating them with metronidazole (MTZ). Blastocystis sp.cultures of 4 sub-types namely 1, 2, 3 and 5 w...

Molecular basis of metronidazole resistance in pathogenic bacteria and protozoa.

The molecular basis of metronidazole resistance has been examined in anaerobic bacteria, such as Bacteroides, Clostridium, and Helicobacter, and anaerobic parasitic protists such as Giardia, Entamoeba, and trichomonads. A variety of enzymatic and cellular alterations have been shown to correlate with metronidazole susceptibility in these pathogens; however, a common theme has been revealed. Res...

Molecular epidemiology of Blastocystis sp

Update on the pathogenic potential and treatment options for Blastocystis sp

Although Blastocystis is one of the most common enteric parasites, there is still much controversy surrounding the pathogenicity and potential treatment options for this parasite. In this review we look at the evidence supporting Blastocystis as an intestinal pathogen as shown by numerous case studies and several in vivo studies and the evidence against. We describe the chronic nature of some i...

Exacerbation of colon carcinogenesis by Blastocystis sp.

Colorectal cancer (CRC) is one the most commonly diagnosed cancers worldwide and the number is increasing every year. Despite advances in screening programs, CRC remains as the second leading cause of cancer deaths in the United States. Oxidative stress plays an important role in the molecular mechanisms of colorectal cancer (CRC) and has been shown to be associated with Blastocystis sp., a com...
