Stool findings in "chronic dysentery"
Abstract:
Faecal samples from 63 subjects with self-diagnosis of "chronic dysentery" and 50 control subjects were examined under light microscope. Vegetative form of E.h. was not detected in any of them. E.h. cyst was found in 6.3% of the "chronic dysentery" subjects and in 16% of the control subjects. E. coli and Giardia were also detected less often in the "chronic dysentery" than the control subjects. Lower incidence of protozoa namely E.h. cyst, E. coli cyst or Giardia in the former group was probably due to frequent intake of antiamoebic agents which are also effective against other intestinal protozoa. Incidence of Ascaris, hookworm, and Trichuris was not appreciably different in the two groups. More subjects in the "chronic dysentery" group had normal stool findings (31%) as compared to the control subjects (16%). It has been inferred that E.h. infection is not the cause of symptoms of "chronic dysentery".
Insights
Entamoeba histolytica (E.h.) infection is unlikely to cause chronic dysentery symptoms. Studies found fewer E.h. cysts in those with self-diagnosed chronic dysentery compared to controls.
Area of Science:
- Medical Parasitology
- Gastroenterology
- Infectious Diseases
Background:
- Chronic dysentery is often attributed to parasitic infections.
- Entamoeba histolytica (E.h.) is a common intestinal protozoan parasite.
Purpose of the Study:
- To investigate the association between E.h. infection and self-diagnosed "chronic dysentery".
- To compare the prevalence of intestinal protozoa and helminths in patients with "chronic dysentery" versus healthy controls.
Main Methods:
- Microscopic examination of faecal samples from 63 "chronic dysentery" patients and 50 controls.
- Detection of protozoa (E.h., E. coli, Giardia) and helminths (Ascaris, hookworm, Trichuris).
Main Results:
- E.h. vegetative forms were undetected. E.h. cysts were found in 6.3% of "chronic dysentery" patients vs. 16% of controls.
- E. coli and Giardia were less prevalent in "chronic dysentery" patients.
- Higher prevalence of normal stool findings (31%) in "chronic dysentery" patients compared to controls (16%).
Conclusions:
- E.h. infection is unlikely to be the primary cause of "chronic dysentery" symptoms.
- Reduced protozoal incidence in patients may be due to antiamoebic medication use.
- Further investigation is needed to determine the etiology of "chronic dysentery".
