dc.description | Intestinal cryptosporidiosis is a diarrheal disease caused by protists of genus Cryptosporidium
that infect a wide variety of hosts, primarily vertebrates. Due to the close contact
between humans and their companion animals, especially dogs and cats, there is concern
about the potential for zoonotic transmission of this enteric protozoan parasite by infected
animals. This study aimed to perform a microscopic and molecular diagnosis of Cryptosporidium
spp. in fecal samples from domiciled dogs and cats. One hundred and nineteen fecal
samples were processed using sugar centrifugal flotation followed by molecular detection of
Cryptosporidium spp. DNA using nested PCR. Subtyping of isolates positive for C. parvum
was performed by sequence analysis of the 60 kDa glycoprotein gene (GP60). Cryptosporidium
oocysts were detected in 7.8% (5/64) and 5.4% (3/55) of the fecal samples from dogs
and cats, respectively. Cryptosporidium canis (n = 3) and C. parvum (n = 2) were the main
species found in dogs, whereas C. felis (n = 3) was prevalent in cats. Subtype IIaA17G2R2
(potentially zoonotic) was identified in samples positive for C. parvum. Despite the low prevalence
of Cryptosporidium observed in the domiciled dogs and cats, the presence of potentially
zoonotic C. parvum in dogs evidences a public health concern. Further research is
needed to better understand the epidemiology, source, and potential impacts of Cryptosporidium
infection in cats and dogs. | |
