[Balantidiasis in a rural community from Bolivar State, Venezuela].

Balantidium coli is the etiologic agent of balantidiasis, an infrequent zoonose of worldwide distribution. The objective of the present study was to determine the clinical and epidemiological aspects of balantidiasis in a rural community in the Bolivar State in Venezuela. Fifty persons and 12 pigs were evaluated. Fecal samples were analyzed by direct examination and by the methods of Faust and Willis. The global rate of intestinal parasitoses detected was 88.0% for the human population and 83.3% for the pigs. The prevalence of human and porcine balantidiais was 12.0% (6/50) and 33.3% (4/12), respectively. The disease was only detected in children, all of them with multiple parasites and with clinical manifestations. Deficient environmental sanitation, absence of basic services in the dwellings, low socioeconomic level, and the presence of pigs infected with B. coli are the factors that explain and maintain the conditions favorable to the transmission of balantidiasis in the population studied.

Invasive balantidiasis presented as chronic colitis and lung involvement.

A unique case of chronic balantidiasis is described, presenting with chronic colitis and inflammatory polyposis of the rectum and sigmoid colon and an intrapulmonary mass. Histology of the colonic polyps showed Balantidium coli, and both Aspergillus and Balantidium coli were found in the aspirate of the pulmonary mass. The patient was treated with doxycycline HCl 100 mg/day for 10 days with complete clinical recovery and marked improvement of the endoscopic appearance of the colonic mucosa.

Clinical trials with metronidazole in human balantidiasis.

Therapeutic activity of metronidazole against Balantidium coli was evaluated by using two drug regimens in 20 human cases of balantidiasis. All patients also harbored Trichuris trichiura. Children received a total amount of drug that varied from 2.5 g during 5 days to 7.5 g in a period of 10 days. Adults were given 5 g in 5 days or 12.5 g during a period of 10 days. In all patients B. coli disappeared after the 4th day of treatment. Frequent posttreatment stool examination remained negative. All patients tolerated the drug well and there were no side effects.

[Colonic balantidiasis].

Balantidium coli is a Protozoa that is not usually pathogenic in man, although epidemics have been described in tropical areas. It mainly affects the colon and clinical presentation varies from asymptomatic forms to severe dysenteric syndromes. We present a case of endoscopically diagnosed colonic balantidiasis and review the most important characteristics of this parasite-induced disease.
