An atypical case of chronic paracoccidioidomycosis in a dog caused by a fungus from the Paracoccidioides brasiliensis complex.

Paracoccidioidomycosis (PCM) is a systemic mycosis endemic in Latin American countries and one of the most important fungal diseases regarding incidence and mortality in humans. PCM has also been described in some animal species such as dogs. In this study we describe a new case of PCM disease in a dog that differed from previous records in the literature which includes a progressive evolution of fungal dermatitis causing a deforming lesion in the nose, like those found in human patients, and humoral response against gp70 instead of gp43, the major diagnostic antigen for human PCM.

Histopathological survey of free-ranging neotropical bats with dermatitis.

Bats have a fundamental ecological role, and no wildlife disease has decimated more individuals than white-nose syndrome (WNS). This impactful mycosis has raised the importance of monitoring disease threats to bat populations. In this study, we aimed to investigate gross skin lesions in neotropical bats by histopathology to survey the occurrence of dermatitis that could resemble WNS cases in Brazil.

Seroprevalences Against Paracoccidioides cetii: A Causative Agent for Paracoccidiomycosis Ceti (PCM-C) and Coccidioides posadasii; for Coccidioidomycosis (CCM) in Dall's Porpoise (Phocoenoides dalli) and Harbor Porpoise (Phocoena phocoena) Stranded at Hokkaido, Japan.

Paracoccidiodomycosis ceti (PCM-C) is a zoonotic mycosis characterized by chronic granulomatous cutaneous lesions in cetaceans. It is distributed worldwide and is caused by an unculturable fungus; Paracoccidioides cetii. On the other hand, coccidioidomycosis (CCM), caused by Coccidioides spp.

In vitro Arthrographis kalrae biofilm formation: Scanning electron microscopy and cytotoxic analysis.

To our knowledge, this study represents the first demonstration of Arthrographis kalrae biofilm formation in vitro by scanning electron microscopy and the distinct cytotoxic activity between planktonic and biofilm extracts on RAW 264.7 cell line. Higher activity was observed with biofilm.
