Original publication title: Sub-clinical infection and asymptomatic carriage of Cryptococcus gattii in dogs and cats during an outbreak of cryptococcosis.
Plain-English summary
A study found that some dogs and cats living on Vancouver Island were carrying a fungus called Cryptococcus gattii, which can cause serious illness. Out of 280 dogs and 94 cats tested, a small number had the fungus in their noses or showed signs of infection in their blood. Cats were found to be more likely than dogs to test positive for this fungus. While these pets didn't show any symptoms, this finding is important for understanding the outbreak of cryptococcosis in the area.

Abstract
Since 1999, Cryptococcus gattii has emerged as an important pathogen of humans and animals in British Columbia, Canada. Nasal swabs and serum samples were collected from dogs and cats residing within the Coastal Douglas Fir biogeoclimatic zone on Vancouver Island, where clinical cases have been reported. Deep and superficial nasal fungal cultures of 280 dogs and 94 cats identified four (4.3%) cats and three (1.1%) dogs with C. gattii serotype B in their nasal cavity. Serum samples collected from 266 dogs and 84 cats identified six (7.1%) cats and two (0.8%) dogs with a positive cryptococcal antigen titer. Overall cats were 4.4 times more likely than dogs to be positive on one or both tests. Identification of sub-clinical infection and nasal colonization is an important step in the characterization of the outbreak of clinical cryptococcosis on Vancouver Island.
