1/9. balantidium coli pneumonia in an immunocompromised patient. A fatal case is reported of balantidium coli pneumonia in a 71-y-old woman suffering from anal cancer. The diagnosis was made by the discovery of motile trophozoites in a wet mount from bronchial secretions. The usual habitat of the parasite is the colon; lung balantidiasis is very rare. ( info) |
| balantidium coli is the only parasitic ciliate of man. It is a flattened oval organism covered with cilia, and a gullet at the anterior end. It is infrequently pathogenic for man, although epidemic buds in tropical zones have been described. The infection fundamentally affects the colon and causes variable clinic pictures, from asymptomatic to serious dysenteric forms. We present a case of parasitologically diagnosed as causes of diarrhea in a patient with non-Hodgkin's lymphoma from turkey. In order to find out the causative etiologic agent of diarrhea, stool samples were examined by native, lugol and flotation methods and we detected moving trophozoites, which were approximately 60 microm long and 35 microm wide. These bodies were diagnosed as balantidium coli. This case underlines that balantidium coli should also be considered as a possible pathogen in immunocompromised patients with diarrhea. ( info) |
| The case reported here concerns an alcoholic pork-butcher who presented with severe colitis with peritonitis, caused by the only ciliate protozoan capable of infecting humans, balantidium coli. This parasite is common in a variety of domestic and wild mammals, mainly pigs; however, its prevalence rate in humans is very low--particularly in industrialised, northern countries, including france. The infection is most frequently acquired by ingesting food or water contaminated by pig faeces, and it may be asymptomatic or may cause acute diarrhoea. Specific antibiotic treatment is efficacious, and it is important to consider the risk of this parasitic disease in susceptible patients presenting with bloody diarrhoea. ( info) |
4/9. Human balantidiasis. A case report. A 58-year-old woman, who presented to hospital with melaena and faecal peritonitis due to a perforated terminal ileum, was found to be infected with balantidium coli. This protozoan parasite is commonly found in pigs, but can infect man, and may mimic amoebic infection. The diagnosis may be missed unless fresh stools are examined immediately. The patient died from septicaemia. ( info) |
| balantidium coli were detached in a routine cytologic smear of ascitic fluid. The morphologic features were clearly discernible in the Papanicolaou stained smears. ( info) |
6/9. 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. ( info) |
7/9. balantidiasis: report of a fatal case with appendicular and pulmonary involvement. A case of fatal balantidial infection with appendicular and pulmonary involvement in a Venezuelan farmer is reported. The clinical, post-mortem and histological features are described. ( info) |
8/9. dysentery caused by balantidium coli--report of two cases. The authors present two cases of dysentery caused by balantidium coli with numerous colonic ulcers, documented by colonoscopy and diagnosed by endoscopic biopsies. The positive rectal exudate in one case permitted the isolation and ultrastructural study of the trophozoites. The good response to tetracyclines in the younger patient was not repeated in the older patient, who died in septic shock despite antibiotic therapy. The authors report the endoscopic findings and comment on the differential endoscopic diagnosis between parasitic and other organic colitis in view of the rarity of these examples as isolated cases in Western countries.

9/9. Case report of balantidium coli in human from south of Tehran, iran. A Patient with balantidiasis in an urinary bladder is reported. trichomonas vaginalis were identified and no other cause of the haematuria was apparent. This condition didn't common and may be linked to ectopic balantidium in urinary bladder. ( info) |
