RESUMEN
The clinical and laboratory findings in puppies naturally infected with canine coronavirus (CCoV) and/or canine parvovirus (CPV) were compared with findings in uninfected puppies. Lymphopenia was the only parameter related to CCoV infection that was statistically significant; vomiting, anorexia, lethargy, hemorrhagic fluid diarrhea, leukopenia, lymphopenia, thrombocytopenia, hypoglycemia, and hypoproteinemia were correlated with CPV infection.
Résultats cliniques, hématologiques et biochimiques chez des chiots atteints de l'entérite à coronavirus et à parvovirus. Les résultats cliniques et de laboratoire chez des chiots naturellement infectés par le coronavirus canin (CoVC) et/ou le parvovirus canin (PVC) ont été comparés aux résultats des chiots non infectés. La lymphopénie était le seul paramètre statistiquement significatif associé à l'infection par le CoVC; les vomissements, l'anorexie, la léthargie, la diarrhée liquide hémorragique, la leucopénie, la lymphopénie, la thrombocytopénie, l'hypoglycémie et l'hypoprotéinémie étaient tous associés à l'infection par le PVC.(Traduit par Isabelle Vallières).

The size of urban cat colonies is limited only by the availability of food and shelter; therefore, their population growth challenges all known population control programs. To test a new population control method, a free-roaming feral cat colony at the Zoological Park in the city of Rio de Janeiro was studied, beginning in 2001. The novel method consisted of performing a hysterectomy on all captured female cats over 6 months of age. To estimate the size of the colony and compare population from year to year, a method of capture-mark-release-recapture was used. The aim was to capture as many individuals as possible, including cats of all ages and gender to estimate numbers of cats in all population categories. Results indicated that the feral cat population remained constant from 2001 to 2004. From 2004 to 2008, the hysterectomy program and population estimates were performed every other year (2006 and 2008). The population was estimated to be 40 cats in 2004, 26 in 2006, and 17 cats in 2008. Although pathogens tend to infect more individuals as the population grows older and maintains natural behavior, these results show that free-roaming feral cat colonies could have their population controlled by a biannual program that focuses on hysterectomy of sexually active female cats.
