Geotrichosis is a world-wide mycosis caused by species. We report a rare case of an invasive cutaneous infection by in a female patient with undiagnosed diabetes mellitus. The patient presented with right facial swelling not responding to antibiotics and could not recall trauma to the site of the lesion. Histological examination showed fungal hyphae invading salivary glands and bony tissues, and was isolated from the culture of biopsy material. Matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry (MS) confirmed the fungal species. Broth microdilution showed low minimum inhibitory concentrations (MICs) for itraconazole, posaconazole, voriconazole and amphotericin B. Treatment with sequential administration of intravenous amphotericin B with voriconazole followed by itraconazole led to the resolution of the lesion.

Peritoneal dialysis (PD) related peritonitis is usually caused by bacteria, but viruses and fungi could also affect the peritoneal membrane and cause cloudy effluent with negative bacterial cultures. We present a case of a PD patient who survived fungal peritonitis caused by (March 2015) and COVID-19 pneumonia (April 2021) with peritonitis probably caused by the virus. The fungal peritonitis followed one episode of exit-site infection and two episodes of bacterial peritonitis treated with a wide-spectrum antibiotic. The patient's PD catheter was removed immediately upon the diagnosis of fungal peritonitis, and an antifungal treatment was continued for 3 weeks after catheter removal. The new peritoneal catheter was reinserted 8 weeks after complete resolution of peritonitis, and the patient continued treatment with PD. The patient developed severe Covid-19 pneumonia with a sudden appearance of cloudy peritoneal effluent. There was no bacterial or fungal growth on the effluent culture. A PCR test for in peritoneal effluent was not performed. The peritoneal effluent became transparent with the resolution of the severe symptoms of Covid-19 pneumonia.

The identification of the fungal species belonging to the healthy microflora in animals is a precondition for the recognition of pathological processes causing them. The aim of this study was to investigate the presence of potentially pathogenic fungi in the feces of wild birds collected in Screening Centers. Samples were collected from the feces of 50 cages with different species of birds. The samples were processed according to the modified method STAIB and the plates incubated at 32 °C for up to ten days with daily observation for detection of fungal growth. The isolation of the following species was observed: Malassezia pachydermatis, Candida albicans, C. famata, C. guilliermondii, C. sphaerica, C. globosa, C. catenulata, C. ciferri, C. intermedia, Cryptococcus laurentii, Trichosporon asahii, Geotrichum klebahnii, Aspergillus spp., A. niger and Penicillium spp. Knowing the character of some opportunistic fungi is important in identifying them, facilitating the adoption of preventive measures, such as proper cleaning of cages, since the accumulation of excreta may indicate a risk for both health professionals and centers for screening public health.
