The aim of this study was to screen for the presence of carbapenemase-producing Enterobacteriaceae (CPE) isolates from bat guano in Bejaia, Algeria. Guano samples ( = 110) were collected in Aokas's cave, Bejaia, Algeria, between March and May 2016. Samples were plated on MacConkey agar supplemented with ertapenem (0.5 mg/L) and vancomycin (32 mg/L). The isolates were identified and antimicrobial susceptibility was determined using disk diffusion method. Carbapenemase, extended spectrum β-lactamases, plasmid-mediated AmpC, and plasmid-mediated quinolone resistance genes were studied using PCR and sequencing. Clonal relatedness was studied using multilocus sequence typing (MLST). Two CPE isolates were identified as . PCR and sequencing identified the OXA-48 in one strain (CS34) and KPC-3 in the other strain (CS63). CS63 was found to carry and genes. The MLST showed that CS63 was assigned to ST512, whereas CS34 belonged to ST1878. This is the first description of CPE from bats' guano.

The study of the Brazilian cave mycobiota has revealed a rich but highly diverse assemblage of fungi, with , , and being the most frequently reported genera. The present study investigated the airborne fungi and fungi obtained from the bodies of bats, guano, and the soil/sediment from the caves Urubu (in the Atlantic Forest) and Furna Feia (in the Caatinga dryland forest) in the Northeast region of Brazil. Fungal strains were identified based on morphological features and multilocus phylogenetic analyses of ITS, beta-tubulin (), calmodulin (), and RNA polymerase II second largest subunit () sequences.

Bats play key roles in ecosystem functions and provide services to human populations. There is a need to protect bat populations and to mitigate the risks associated with pathogen spillover. Caves are key habitats for many bat species, which use them as roosting and breeding sites.

Histoplasmosis, caused by the fungus , is a significant public health concern in endemic regions like Mexico. Immunocompromised individuals, especially those with HIV infection and those exposed to nitrogen-rich environments, such as bird excrement or bat guano, are particularly vulnerable. This case report describes a middle-aged patient with jaundice in the skin and mucous membranes.

is a pathogenic dimorphic fungus with evolving epidemiology. Initially described as endemic to the Ohio and Mississippi river valleys, the infection now regularly occurs in central and eastern United States, with cases reported across the entire country. Transmission happens via inhalation of conidia during activities that disturb fungal hyphae.
