Blastocystis hominis is a single-celled eukaryotic organism that inhabits the gastrointestinal tract of humans and various animals. [1] This stramenopile exhibits significant genetic diversity and has become an organism of increasing scientific interest due to its widespread distribution and controversial role in human health. [ 2 ]
Blastocystis has low host specificity, and many different species of Blastocystis can infect humans, [3] and by current convention, any of these species would be identified as Blastocystis hominis. Blastocystis is one of the most common human parasites in the world and has a global distribution.
Blastocystosis refers to a medical condition caused by infection with Blastocystis. Blastocystis is a protozoal, single-celled parasite that inhabits the gastrointestinal tracts of humans and other animals.
Blastocystis spp. intestinal direct microscopy of stool (PCR, antibody) • worldwide: one of the most common human parasites [1] [2] • Developing regions: infects 40–100% of the total populations [1] [2] [3] eating food contaminated with feces from an infected human or animal Cryptosporidiosis: Cryptosporidium spp. intestines stool widespread
He described Blastocystis hominis and Entamoeba dispar. The latter species helped to explain why most people who appeared to be infected with Entamoeba histolytica were asymptomatic. However, because there are no morphological differences between the two species, his proposal was largely ignored for over 50 years before being proven correct ...
Blastocystis is a single-celled protozoan which infects the large intestine. Physicians report that patients with infection show symptoms of abdominal pain, constipation, and diarrhea. [54] [55] [56] One study found that 43% of IBS patients were infected with Blastocystis versus 7% of controls. [49]
Aggravating or contributory microbes in Tourette's may include the bacteria Mycoplasma pneumoniae, [113] Chlamydia pneumoniae, Chlamydia trachomatis, and the protozoan parasite Toxoplasma gondii. [114] Vasculitis: Vasculitis is associated with HIV, parvovirus B19, [75] and hepatitis B virus. The hepatitis C virus is an established cause of ...
Nitazoxanide is an effective first-line treatment for infection by Blastocystis species [11] [12] and is indicated for the treatment of infection by Cryptosporidium parvum or Giardia lamblia in immunocompetent adults and children. [1]
