| 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) |
2/8. Isolation of escherichia coli O5 :H-, possessing genes for shiga toxin 1, intimin-beta and enterohaemolysin, from an intestinal biopsy from an adult case of bloody diarrhoea: evidence for two distinct O5 :H- pathotypes. Two typical coliforms from an intestinal biopsy from an adult case of bloody diarrhoea carried genes encoding intimin-beta, stx(1) and ehxA, and produced verocytotoxin 1 and enterohaemolysin in culture. Both were biochemically typical escherichia coli O5 :H(-), apart from producing urease. Such O5 isolates represent a human pathogenic E. coli lineage. ( info) |
| Enteroinvasive escherichia coli (EIEC) is an important agent of pediatric diarrhea and dysentery in developing countries. We report a life-threatening severe dysentery case due to EIEC in a malnourished 4-month-old male, native Indian infant co-infected with rotavirus. The severe gastrointestinal bleeding anemia and hypovolemic shock was successfully treated with IV blood transfusions, rehydration and antibiotic therapy. ( info) |
4/8. Isolation of vibrio mimicus from a case of acute diarrhoea--a case report. Over a four months period (June to September, 2003) 111 stool samples from cases of acute diarrhoea were screened for Vibronaceae in department of microbiology, Smt. N. H. L. Municipal medical college, Ahmedabad. All the isolates were identified by standard laboratory technique. A total of 36 species belonging to vibrionaceae were isolated. Phage typing of all these Vibronaceae were done at National Institute Of cholera and Enteric disease, Kolkata. Out of 36 isolates, 35 were Vibrio cholereae and only one was vibrio mimicus. We report this case because of rare strain. ( info) |
| Spiral shaped bacteria have frequently been demonstrated from human faeces. Their role in causation of disease is, however, controversial; as they have been found to colonise the lower gastrointestinal tracts of both symptomatic and asymptomatic individuals. Here we report a case in which spiral shaped motile, gram negative and nonflagellated bacteria, probably belonging to the genus borrelia, were demonstrated and associated with acute bloody diarrhea in a cardiac patient. The condition could successfully be treated with short course of metronidazole. The relevant and up to date literature on this problem is also reviewed. ( info) |
6/8. Case report of plesiomonas shigelloides-associated persistent dysentery and pseudomembranous colitis. An adult Bangladeshi woman had persistent bloody diarrhea. Repeated stool cultures yielded plesiomonas shigelloides in pure growth. Tissue specimens of the colon were consistent with pseudomembranous colitis. Treatment with tetracycline, to which the isolate was susceptible, brought prompt recovery; the stool cultures became negative and the serum antibody titer against P. shigelloides lipopolysaccharide, as measured by hemagglutination inhibition with P. shigelloides lipopolysaccharide-sensitized sheep erythrocytes, declined from 1:160 to 1:40.

7/8. 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) |
8/8. 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.
