Clinically, dysentery manifests itself with varying degrees of intensity, and it is often impossible without microscopical examination to determine between the amoebic and bacillary forms. In well-marked cases the following are the chief symptoms. The attack is commonly preceded by certain premonitory indications in the form of general illness, loss of appetite, and some amount of diarrhoea, which gradually increases in severity, and is accompanied with griping pains in the abdomen (tormina).
In amoebic dysentery, warm injections of quinine per rectum have proved very efficacious, are usually well tolerated, and are not attended with any ill effects.
We were faced with a choice of drinking the water and getting amoebic dysentery or spending a rough night suffering from thirst.
Alternatively, for reasons that remain unclear, E. histolytica trophozoites can invade the colonic epithelium, causing amoebic colitis.
John Roger Stuart Moss died of amoebic dysentery on 20th June 1943.
Although the presence of haematophagous amoebic trophozoites on stool examination strongly correlates with E. histolytica infection, this finding is infrequent (Ref.
The sensitivity of microscopy for identifying amoebic trophozoites in liver abscess pus is only ~25% at best (Ref.
(For the pathology see Digestive Organs.) Recently considerable advance has been made in our knowledge of dysentery, and it appears that there are two distinct types of the disease: (1) amoebic dysentery, which is due to the presence of the amoeba histolytica (of Schaudinn) in the intestine; (2) bacillary dysentery, which has as causative agent two separate bacteria, (a) that discovered by Shiga in Japan, (b) that discovered by Flexner in the Philippine Islands.
Broad-spectrum bacteriostatic agents, the tetracyclines may be effective against a wide variety of microorganisms, including rickettsia and amoebic parasites.
Serological test methods for the detection of anti-amoebic antibodies remain extremely useful for the diagnosis of amoebic liver abscess.
