Presentation Transcript

  1. CILIATES • Balantidium coli only ciliate infecting humans • large and diverse group • majority are free-living • covered with rows of cilia • defining characteristic is nuclear dimorphism • micronucleus (genetic) • macronucleus (somatic) • sexual reproduction involving conjugation

  2. Ciliate Reproduction

  3. Balantidium coli Balantidosis • aka, balantidiasis, balantidial dysentery • symptoms: acute diarrhea with mucus and blood, cramps • diagnosis: identify cyst or trophozoite in feces • treatment: tetracycline or iodoquinol • prevention: same as other fecal-oral diseases • world-wide distribution • especially prevalent in tropics • rarely exceeds 1% • common in pigs and monkeys • unlikely to be reservoirs • usually non-pathogenic commensal in l. intestine • can invade intestinal epithelium and cause ulceration with dysentery-like symptoms

  4. Balantidium coli ~70 x 45 m (up to 200 m) ~55 m

  5. unstained trichrome eosin
