Abstract
An overall 19.63 percent infection was observed in domestic and zoo animals
in and around Ranchi.
Zoo animals had significantly higher gastrointestinal protozoa (35.75%) than
domestic animals (17.40%).
E.histolytica and B.coli were common gastrointestinal protozoa infecting
domestic and zoo animals in and around Ranchi.
Among zoo animals, higher degree of gastrointestinal protozoan infection was
found in lion (90%), and monkey (85%).
Among domestic animals, pigs (93 %) and dog (73.52%) had a higher degree
of gastrointestinal protozoan infection.
B.coli infected pigs were controlled effectively by oxytetracycline (100% on
3rd day of observation) and Metronidazole +Furazolidone combination (100%
on 5th day of observation).
Initially B.coli infected pigs had decreased Hb, PCV, and TEC values, but
these values returned towards normal ranges after 7th day of observation.
The DLC values of B.coli infected pigs showed decreased values of
neutrophils, and lymphocytes, and increased eosinophils values which came
towards normal range on 7th day of observation.
The average body weight gain in oxytetracycline and metronidazole +
furazolidone combination treated T & D piglets showed higher value viz.35.25
± 1.64 kg and 28.08 ± 1.75 kg of body weight respectively than untreated
infected control piglets (15.75 ± 2.39).
The average body weight gain in oxytetracycline and metronidazole +
furazolidone combination treated desi piglets showed higher body weight viz.
36.67±1.07 kg and 32.50±0.96 kg respectively than untreated infected control
piglets (22.00±0.88 kg).
Of both the treatment groups, the group treated with oxytetracycline had
significantly higher body weight gain, 35.25 ± 1.64 kg and 36.67±1.07 kg in
both T & D and desi piglets, respectively than metronidazole +furazolidone
combination treated T & D and desi piglets (28.08 ± 1.75 kg, 32.50±0.96 kg,
respectively).
Zoonotic gastrointestinal infections were observed in both domestic and zoo
animals in and around Ranchi. Gastrointestinal protozoan infections in human
population could be presumed to be acquired from the environmental
contamination by the zoo and domestic animals. The present findings have
provided very useful information for adopting suitable chemoprophylactic
measures to reduce the risk of gastrointestinal protozoan infection in domestic
animals and zoo animals.
The observation on different haematological parameters during B.coli
infection and their treatment indicated that the harm caused by B.coli in pigs
could be reduced to a greater extent by suitable therapeutic management.
Application of suitable control packages were found to be very encouraging
for maintaining optimum health and economical pig production.
Oxytetracycline drugs showed higher efficacy than metronidazole +
furazolidone combination and it showed significantly higher growth in body
weight in both T& D and desi piglets.
