[DISCUSSION] MODULE 2 UNIT 5 Flashcards
Initially identified as Paramecium coli by Malmsten in 1857
Balantidium coli
was later described and placed under a separate genus in 1863
Balantidium coli
B. coli is the causative agent of the zoonotic disease called
balantidiasis, balantidiosis, or balantidial dysentery
This organism is primarily associated with pigs, its normal host.
Balantidium coli
Balantidium coli
Infective stage:
Diagnostic stage:
Cyst
Trophozoite and cyst
Most individuals with (?) are totally asymptomatic, whereas others have symptoms of severe dysentery similar to those seen in patients with amoebiasis.
balantidiasis
Generalized symptoms and signs include
chronic and recurrent diarrhea, abdominal pain, cramping, vomiting, weakness, and weight loss
has a potential to invade tissues
B. coli
are responsible for the intestinal ulcers that are wide-mouthed with rounded base
B. coli trophozoites’ active motility and hyaluronidase
These occur in the ileum, cecum and rectum but there is no extraintestinal spread.
B. coli
Secondary infection is frequent. The main complication is perforation.
B. coli
B. coli Geographical distribution:
Cosmopolitan
B. coli Prevalence: (Phil)
<1%
B. coli Transmission:
Fecal-oral route
Hogs serve as the most important reservoir host for human infection, along with perhaps a few other species of animals.
