(1) Background: Airborne microbes are an integral part of a cave ecosystem. Cave allochtonous airborne microbiota, which occurs mainly during aerosolization from an underground river, from animals, and from visitors, is particularly pronounced in show caves. The impacts of tourists and natural river aerosolization on the cave air were estimated in large cave spaces within the Škocjan Caves; (2) Methods: Simultaneously with the measurements of atmospheric parameters, cultivable airborne bacteria were impacted, counted and identified using MALDI-TOF MS (Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectrometry); (3) Results: A mix of bacteria typically associated with humans and with natural habitats, including a large percentage of non-identified isolates, was found in the cave air. Few of the isolates were attributed to Risk Group 2. A strong positive correlation between tourist numbers and the rise in the concentration of airborne bacteria was indicated. Concentration of airborne bacteria rises to particularly high levels close to the underground river during periods of high discharge. A 10-times lower discharge reflected an approximately 20-times lower concentration of airborne bacteria; (4) Conclusions: Caves that are open and visited contain a diverse airborne microbiota originating from different sources. Enormous cave chambers that display relatively dynamic cave climate conditions do not normally support the enhancement of airborne bacterial concentrations.

A novel aerobic, non-motile, Gram-positive, pink-orange-pigmented, coccoid marine bacterium, designated strain SJ2T , was isolated from the Gwangalli coast of Korea. The taxonomic position of strain SJ2 T was determined based on 16S rRNA gene sequence analysis, fatty acid patterns and physiological reaction profiles. The full-length 16S rRNA gene sequence of strain SJ2 T showed highest similarity to those of the type strains of Kocuria carniphila and Kocuria marina. Strain SJ2 T exhibited mean levels of DNA-DNA relatedness of 17 and 35 % to the type strains of K. carniphila and K. marina, respectively. Based on these results, strain SJ2 T is considered to represent a novel species of the genus Kocuria, for which the name Kocuria gwangalliensis sp. nov. is proposed.

“…The blood cultures were initially processed using the BacT/ALERT device (bioMérieux, l'Etoile, France) and the isolates were initially characterized by means of the Vitek2 identification system (bioMérieux). The device named the isolates Kocuria varians (formerly Micrococcus varians), which was not consistent with the characteristics of this species 4 . As reported by Cunha et al 5 , some Staphylococcus strains have often been identified as Kocuria in using the Vitek2 system.…”

Caracterização de uma nova espécie de Staphylococcus coagulase-negativo (Staphylococcus pettenkofer) isolada de hemoculturas de um paciente hospitalizado em Porto Alegre, Brasil Pedro Alves d'Azevedo 1 , Guilherme Comin 1 and Vlademir Cantarelli 2 ABSTRACT Introduction: Staphylococcus pettenkoferi was originally isolated and described by Trülzsch et al (2002). In this study, we characterized two isolates of this newly described species. Methods: Blood cultures were initially processed using the BacT/ALERT device, and the isolates were initially characterized using the Vitek2 identification system. Results: The initial characterization revealed slow-growing Gram-positive cocci that formed opaque colonies on sheep blood agar. Other phenotypic/genotypic tests were performed. Conclusions: We would like to emphasize that this new staphylococcus species is phenotypically similar to other CoNS, especially S. auricularis. This could potentially lead to misidentification of these uncommon species.
