Cryptococcus is an opportunistic yeast that causes life-threatening infections as meningoencephalitis primarily in immunocompromised hosts, generally associated with AIDS. The source of this organism is mainly pigeon excreta; however, other avian species' excreta are implicated as a source of this yeast. The aim of this study was to perform the isolation of yeasts of the Cryptococcus genus from the cloacae of 40 parrots kept in captivity area of the genus Amazona aestiva. These birds were anesthetized, the cloacae washed, and then swabs from the cloaca collected. The yeasts isolated from cloacae birds were studied by phenotypic and genotypic methods. The production of extracellular enzymes as virulence factors (protease and phospholipase) was performed too. From the total of parrots studied, 10 strains of yeasts were isolated. Nine of the strains belonged to the specie Cryptococcus albidus var. albidus and one sample belonged to the specie Cryptococcus laurentti. The extracellular enzymes research demonstrated that 80% of the isolates were phospholipase producers and all of them were protease positives. These results suggest that not just the environment but also the birds of A. aestiva genus may be the carriers of C. albidus. We point out that the strains produced virulence factors. This is the first report of the isolation of C. albidus var. albidus of A. aestiva parrots and to assert that this bird is a special ecological niche of capped yeast.

“…In this study, C. albidus was isolated from all analyzed sites in one healthy animal (3.22%) only, which demonstrates that this yeast was probably present in these sites transiently. This species is encapsulated and thought to be saprophytic, but it is rarely associated to clinical cases, although it has been isolated in system infection cases and pyelonephritis in dogs (Newman et al , 2003; Labrecque et al , 2005; Kano et al , 2008). …”

The oral microbiota of humans and animals is made up of a wide variety of yeasts and bacteria, but microbiota of dogs is not totally described. Although such identification is an important step to establish the etiopathogenesis and adequate therapy for the periodontal disease The aim of this study was to evaluate and correlate oral alterations with the presence of yeasts in oral cavity of female dogs. After clinical evaluation samples from healthy and from dogs with oral diseases were obtained from three different oral sites by swabs, curettes, millimeter periodontal probes and HA membrane tip in cellulose ester. Yeast identification was performed through macroscopic and microscopic colony features and biochemical tests. Dental calculus was the most prevalent occurrence in the oral cavity of 59 females. However, the isolation of yeasts was significantly higher (p < 0.05) in animals suffering from halitosis. Eleven yeast species were identified, namely: Malassezia pachydermatis, Rhodotorula spp., Candida albicans, C. catenulata, C. famata, C. guilliermondii, C. parapsilosis, C. intermedia, Trichosporon asahii, T. mucoides and Cryptococcus albidus. It could be concluded that the yeasts are part of the microbiota from the different sites of the oral cavity of the female canines studied without causing any significant alterations except halitosis.

“…Furthermore, cats infected with FeLV or FIV are not considered to be at increased risk for infection with any of the cryptococcal species, but may experience more difficulty in clearing infection compared with cats not infected with retroviruses 3 . Cryptococcus albidus has recently been identified as another species pathogenic to dogs and cats, 20,21 and other isolates reported in domestic animals include Cryptococcus magnus and Cryptococcus laurentii , both isolated from ear infections as these 2 organisms grow poorly at body temperature 22,23 . Pathogenicity related to individual Cryptococcus species is assessed in the laboratory by the capacity of the pathogenic strains ( C. neoformans–C.…”

Cryptococcosis is a fungal disease that occurs throughout the world. Recent reclassification of Cryptococcus species along with a change in the distribution pattern has prompted reevaluation of the organism and the diseases caused by this pathogen. This review highlights the emergence of Cryptococcus gattii as a primary pathogen in North America and summarizes our current understanding of the disease in mammals and birds.
