Pit Bull Chat Forum

Welcome to Pit Bull Chat!

We are a diverse group of Pit Bull enthusiasts devoted to the preservation of the American Pit Bull Terrier.

Our educational and informational discussion forum about the American Pit Bull Terrier and all other bull breeds is a venue for members to discuss topics, share ideas and come together with the common goal to preserve and promote our canine breed of choice.

Here you will find discussions on topics concerning health, training, events, rescue, breed specific legislation and history. We are the premier forum for America’s dog, The American Pit Bull Terrier.

We welcome you and invite you to join our family.

    We decided to spruce things up and fix some things under the hood. If you notice any issues, feel free to contact us as we're sure there are a few things here or there that we might have missed in our upgrade.

Fungal Infections

Most agents of systemic mycoses exist as saprophytes in soil, in decaying vegetation and dung, and on keratinized animal tissues. The soil reservoir is the primary source of most infections, which can be acquired by inhalation, ingestion, or traumatic introduction of fungal elements.

Pathogenic fungi establish infection in apparently normal hosts, and such diseases as histoplasmosis, coccidioidomycosis, and blastomycosis are regarded as primary systemic mycoses. Opportunistic fungi usually require a host that is debilitated or immunosuppressed (eg, by such stresses as captivity, metabolic acidosis, malnutrition, viral infections, or neoplasia) to establish infection. Prolonged administration of antimicrobials or immunosuppressive agents appears to increase the likelihood of infection by the opportunistic fungi that cause diseases such as aspergillosis, mucormycosis, cryptococcosis, and candidiasis, which may be focal or systemic. Cryptococcosis has been recorded in apparently healthy animals, possibly due to some subtle host defect (possibly in cell-mediated immunity).

Clinical findings and gross lesions are not definitively diagnostic of systemic mycoses; microscopical identification or culture of the organism, or both, are required. Identification of the fungus and the tissue reaction via microscopical examination of exudates and biopsy material is adequate for diagnosis of histoplasmosis, cryptococcosis, blastomycosis, coccidioidomycosis, and rhinosporidiosis. Other diseases, such as candidiasis, aspergillosis, and mucormycosis, require both cultural isolation and microscopical evaluation for a definitive diagnosis. These fungi are also common contaminants of cultures; thus, tissue invasion and reaction must be demonstrated for the culture isolation to be considered significant. Serology may be useful for diagnosis (and prognosis) of some mycotic diseases such as histoplasmosis, blastomycosis, cryptococcosis, and coccidioidomycosis.
