ABSTRACT
Javdani M, Rezaei F, Hashemnia M, Chalechaleh A, Nikousefat Z., Survey
of gastrointestinal parasites in laboratory animals. Onl
J Vet Res., 18(3): 269-277,
2014. Incidence of gastrointestinal parasites in laboratory animals is reported. Sixty laboratory Sprague Dawley rats, 20 short hair England
guinea pigs and 20 Dutch rabbits were necropsied
for intestinal parasites Seventy percent were infested but only
nematodes and cestodes were found. 86.66% rats were infested by 3 nematodes (56.66% Aspiculuris tetraptera,
43.66% Syphacia obvelata
and 16.66% Syphacia muris) and 3 cestodes
(10% Cysticercus
fasciolaris, 41.66% Hymenolepis
diminuta and 11.66 Hymenolepis
nana). 17 guinea pigs (85%) were infested by Nematoparaspidora
uncinata and 45% of rabbits with Passalurus ambiguous. Maximum
and minimum infection frequency occurred in rats and rabbits, respectively. The parasites are common in laboratory
animals. However,
trematode and protozoa were not found. Inadequate space between animals was
probably the main cause of high infestation rate.
