Enteropathogens identified in cats entering a Florida animal shelter with normal feces or diarrhea.

OBJECTIVE: To determine the frequency of enteropathogens in cats entering an animal shelter with normal feces or diarrhea. DESIGN: Cross-sectional study. ANIMALS: 100 cats evaluated at an open-admission municipal animal shelter in Florida. PROCEDURES: Fecal samples collected within 24 hours after admission from 50 cats with normal feces and 50 cats with diarrhea were tested by fecal flotation, antigen testing, PCR assay, and electron microscopy for selected enteropathogens. RESULTS: 12 enteropathogens were identified. Cats with diarrhea were no more likely to be infected with ≥ 1 (84%) enteropathogens than were cats with normal feces (84%). Only feline coronavirus was significantly more prevalent in cats with diarrhea (58%) than in cats with normal feces (36%). Other enteropathogens identified in cats with and without diarrhea included Clostridium perfringens enterotoxin A (42% and 50%, respectively), Cryptosporidium spp (10% and 20%, respectively), Giardia spp (20% and 8%, respectively), Cystoisospora spp (14% and 10%, respectively), hookworms (10% and 18%, respectively), ascarids (6% and 16%, respectively), Salmonella spp (6% and 4%, respectively), astrovirus (8% and 2%, respectively), feline panleukopenia virus (4% and 4%, respectively), calicivirus (0% and 2%, respectively), and Spirometra spp (0% and 2%, respectively). CONCLUSIONS AND CLINICAL RELEVANCE: In the present study, cats entered the shelter with a variety of enteropathogens, many of which are pathogenic or zoonotic. Most infections were not associated with diarrhea or any specific risk factors such as signalment, source, or body condition, making it difficult to predict which cats were most likely to be infected. It is not possible to test all shelter cats for all possible infections, so practical guidelines should be developed to treat routinely for the most common and important enteropathogens.

Enteropathogens identified in dogs entering a Florida animal shelter with normal feces or diarrhea.

OBJECTIVE: To determine the frequency of enteropathogens in dogs entering an animal shelter with normal feces or diarrhea. DESIGN: Cross-sectional study. ANIMALS: 100 dogs evaluated at an open-admission municipal animal shelter in Florida. PROCEDURES: Fecal samples were collected within 24 hours after admission from 50 dogs with normal feces and 50 dogs with diarrhea. Feces were tested by fecal flotation, antigen testing, PCR assay, and electron microscopy for selected enteropathogens. RESULTS: 13 enteropathogens were identified. Dogs with diarrhea were significantly more likely to be infected with ≥ 1 enteropathogens (96%) than were dogs with normal feces (78%). Only Clostridium perfringens enterotoxin A gene was significantly more common in dogs with diarrhea (64%) than in dogs with normal feces (40%). Other enteropathogens identified in dogs with and without diarrhea included hookworms (58% and 48%, respectively), Giardia spp (22% and 16%, respectively), canine enteric coronavirus (2% and 18%, respectively), whipworms (12% and 8%, respectively), Cryptosporidium spp (12% and 2%, respectively), ascarids (8% and 8%, respectively), Salmonella spp (2% and 6%, respectively), Cystoisospora spp (2% and 4%, respectively), canine distemper virus (8% and 0%, respectively), Dipylidium caninum (2% and 2%, respectively), canine parvovirus (2% and 2%, respectively), and rotavirus (2% and 0%, respectively). CONCLUSIONS AND CLINICAL RELEVANCE: Dogs entered the shelter with a variety of enteropathogens, many of which are pathogenic or zoonotic. Most infections were not associated with diarrhea or any specific dog characteristics, making it difficult to predict the risk of infection for individual animals. Guidelines for preventive measures and empirical treatments that are logistically and financially feasible for use in shelters should be developed for control of the most common and important enteropathogens.
