The cause of dysentery is usually the bacteria from genus Shigella, in which case it is known as shigellosis, or the amoeba Entamoeba histolytica; then it is called amoebiasis. [1] Other causes may include certain chemicals, other bacteria, other protozoa, or parasitic worms. [2] It may spread between people. [4]
Life-cycle of the Entamoeba histolytica. Amoebiasis is usually transmitted by the fecal-oral route, [9] but it can also be transmitted indirectly through contact with dirty hands or objects as well as by anal-oral contact. Infection is spread through ingestion of the cyst form of the parasite, a semi-dormant and hardy structure found in feces.
Life-cycle of Entamoeba histolytica. Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba. [1] Predominantly infecting humans and other primates causing amoebiasis, E. histolytica is estimated to infect about 35-50 million people worldwide. [1] E. histolytica infection is estimated to kill more than 55,000 ...
This technique uses low-energy waves produced from a battery powered device. The device delivers periodic rectangular pulses through an actuator holding a thin piezo plate. The waves spread to the surface, in this case a catheter, creating horizontal waves that prevent the adhesion of planktonic bacteria to surfaces.
The sanitation and hygiene barriers when placed correctly prevent the transmission of an infection through hands, water and food. The F-diagram can be used to show how proper sanitation (in particular toilets, hygiene, handwashing) can act as an effective barrier to stop transmission of diseases via fecal–oral pathways.

The two most common manifestations of E histolytica include colitis (bloody stool with mucus, abdominal pain, and/or diarrhea), and discovery of a liver abscess on imaging. [2] Liver abscesses commonly present as right upper quadrant abdominal pain and fever, with worsening features associated with abscess rupture.
For treatment to be effective against all stages of the amoeba may require a combination of medications. Infections without symptoms do not require treatment but infected individuals can spread the parasite to others and treatment can be considered. Treatment of other Entamoeba infections apart from E. histolytica is not needed. [33]
It can be caused by Acanthamoeba [2] [3] or Entamoeba histolytica. [4]: 421 [5] When associated with Acanthamoeba, it is also known as "cutaneous acanthamoebiasis". [6] Balamuthia mandrillaris can also cause cutaneous amoebiasis, but can prove fatal if the amoeba enters the bloodstream [7] [8] It is characterized by ulcers. Diagnosis of ...
