AB  - An extensive aeromycological survey was performed in the premises of a cultural heritage conservation facility to estimate fungal propagule concentrations in both indoor and outdoor air and seasonal dynamics with regard to temperature and air humidity. The highest average propagule concentration in indoor air was documented in spring, and for outdoor air, in summer. Increased propagule loads were documented in most rooms during winter, fall and spring, and in all examined rooms in summer. Very high propagule concentrations (>25,000 CFU m−3) were reported in ground-floor rooms. The total mycobiota was comprised of 74 fungal species, with a prevalence of Aspergilli and Penicillia. Cladosporium and Penicillium isolates were found to be the most abundant in all seasons in both indoor and outdoor air samples. Among the identified fungi, potential human pathogens, allergens and mycotoxin producers were present. Numerous documented species play an important role in the deterioration of cultural heritage artifacts and are known producers of extracellular enzymes, acids and pigments. Application of a selective medium (M40Y) allowed isolation of various xerophiles and xerotolerant species. Aeromycological analyses are mandatory for determining the appropriate conditions for the protection of the health of conservators, as well as the objects of cultural heritage.

AB  - Amphibian populations have been declining throughout the world in the last several decades. Although
numerous factors, including habitat destruction, pollution, introduced species, and global environmental changes
contribute the most to amphibian population decline, yet many amphibians are dying of infectious diseases.
Recent studies of amphibian skin infections were mainly focused on the presence of chytridiomycosis
neglecting other members of the frogs’ skin communities. Samples for mycological and algological analyses
were collected from 100 individuals belonging to Pelophylax esculenta complex on three localities in South
Banat, Serbia using non-aggressive, rapid and inexpensive “adhesive tape” method for microbial biofilm
observation.
In analysed samples variety of fungal reproductive structures, and in few samples spore germination,
and mycelia formation were detected. Sporulation of some typical soil-borne fungi and the causative agent of
amphibian chromomycosis as well as human phaeohyphomycosis, Fonseceae sp. was detected along with water
mold, Aphanomyces sp. the pathogen responsible for amphibian egg mortality and saprolegniasis of mostly
salamanders and tadpoles. For both pathogens, these were the first reports for green frogs in Serbia. Microscopy
analysis showed the presence of aeroaquatic hyphomycetes (eg. Canalisporium sp.). Besides mycobiota, the
frog's skin has proved to be a good medium for the survival of diatoms (detected in high diversity and
abundance), Cyanobacteria and Chlorophyta.
Adhesive tape method proved itself useful as a consequential diagnostic tool for preliminary
observation of the microbial community on the skin of amphibians including potential pathogens and symbionts.
It provides minimal stress to the studied animal and can be easily applicable in various conditions of field
research.

AB  - Cutaneous microbiota of amphibians is considered
to be an indicator of the health status of examined
individuals, as well as of environmental factors. In
that sense the skin of the captured individuals
belonging to Pelophylax esculenta complex on the
locality Stevanove ravnice within the Special Nature
Reserve “Deliblato Sand” (Serbia) was screened for
the presence of biofilm-forming cyanobacteria,
algae and fungi dwelling directly on frogs’ stratum
corneum. Biofilm was sampled using non-aggressive
“adhesive tape method” and their constituents were
analyzed and characterized microscopically (Carl
Zeiss AxioImager.M1 with AxioVision 4.9 software).
We detected high diversity and abundance
of diatom taxa overall, particularly belonging to
genera Navicula, Gomphonema, Geissleria,
Placoneis and Nitzschia. Cyanobacteria were less
present and with low abundance. Among them
chroococcal genera Gloeocapsopsis, Pseudocapsa
and Aphanocapsa were recorded. Outside of diatoms
and cyanobacteria, genus Chlorella was the
only present photoautotrophic biofilm constituent.
We consider highly mucous green frogs skin as
a favorable environment for the survival of diatoms
and cyanobacteria. Light microscopy analyses of
biofilm fragments revealed the presence of variety
of fungal structures. Documented coenocytic mycelium
with zoosporangium, originated presumably
from oomycetes, as well as septate melanized
hyphae of dematiaceous fungi, suggested colonization
of frog skin from both types of environments
present, water and surrounding vegetation.
A variety of fungal spores (fragmospores, amerospores,
dictyospores, didymospores), and in few
cases spore germination were recorded on frog
skin. Detected biofilm composition was not determinate
by species and gender-specific.

AB  - Recent research of frog skin microbiota were mainly focused on presence of pathogens, especially
Batrachochytrium dendrobatidis, as well as on describing the bacterial communities on their skin. e
specialized amphibian lifestyle where frogs’ skin is in intimate contact with the environment is of primary
importance in determining frogs’ resilience to external factors. Cutaneous microbiota is thus an indicator of
both frog health as well as of environmental factors acting upon frogs. Many of these factors can be
detrimental to frog fitness and it is expected that the first changes in frog fitness could be assessed by
identifying the changes in diversity patterns of frog’s skin epibiotic communities and/or isolating specific
pathogens. Knowledge of these communities and patterns could contribute to more efficient conservation.
Epibiotic communities of the green frog complex (Pelophylax esculenta complex), sampled on three localities
in South Banat, Serbia (Stevanove Ravnice, Jaruga canal, DanubeTisaDanube
Canal) were investigated
using culture depended methods and microscopy techniques. Samples were collected using three sampling
methods: 1) scraping by toothbrush for algal sample 2) swabbing with sterile cotton swabs for fungal sample
and 3) nonaggressive adhesive tape method for both algal and fungal sample. e aim of this research was
describing fungal and algal communities present on frogs’ skin. Culture based methods showed high
diversity of airand
soilborne
fungi (members of genera Acremonium, Alternaria, Aspergillus, Bionectria,
Bipolaris, Botrytis, Cladosporim, Epicoccum, Fusarium, Penicillium, Trichoderma, Ulocladium, to name a few),
which could be considered transients. However, microscopy techniques revealed spore germination, mycelia
formation and sporulation directly on frog skin, of some typical soilborne
fungi eg. Fonseceae sp., causative
agent of amphibian chromomycoses as well as human phaeohyphomycosis. Microscopy analyses of samples
taken or scraped from amphibians’ skin showed the presence of morphological structures belonging to
aeroaquatic hyphomycetes (eg. Canalisporium sp.) and stramenopiles, as well as high abundance of diatoms.
Presence of c. 40 diatom genera was observed with dominance of mostly ubiquitous eurivalent species found
in highly eutrophic waters (members of genera Amphora, Craticula, Cymbella, Cymbopleura, Cymatopleura,
Diploneis, Encyonema, Epithemia, Fallacia, Gomphonema, Luticola, Navicula, Neidium, Nitzschia, Pinnularia,
Planothidium, Rhopalodia, Staurosira and Surirella). Investigation of microbial communities on frog skin is of great importance due to potential detection of
novel amphibian pathogens, and also can lead to better understanding of amphibianmicrobial
interactions,
which in further researches can be used as effective tool in amphibian protection.

AB  - Diversity of subaerial biofilm forming cyanobacteria, algae and fungi was investigated on 10 different substrata from greenhouse of Botanical Garden “Jevremovac”. Out of 37 documented taxa, 16 cyanobacterial and 10 algal taxa were identified. Remaining 11 taxa belong to the Kingdom of Fungi. The highest diversity of biofilm forming microorganisms, a total of 24 taxa, was detected on the corroded metal surface, while significantly lower number of taxa was recorded on other examined substrata. Cyanobacterium Porphyrosiphon sp., diatom Achnanthes sp. and green algae Chlorella sp. and Chlorococcum minutum were the most frequently encountered photosynthetic components of biofilms. In all analyzed samples, Trichoderma sp., followed by Cladosporium sp. and Rhizopus stolonifer, were the most frequently identified fungi.

AB  - It is known that diatoms may be present on the skin of various animals (whales, dolphins, manatees, turtles…) (Frankovich et al. 2015, Wetzel et al. 2012). In our study diatoms were collected from the skin of two green frogs’ species: Pelophylax esculentus and P. ridibundus. Studied frogs were captured from the Special Nature Reserve “Deliblatska Pescara” at the locality Stevanove ravnice (Vojvodina province, Serbia). Two sampling methods were performed: (1) nonaggressive adhesive tape method (Urzì and de Leo 2001) and (2) scraping by toothbrush. In laboratory conditions, samples taken by the first method were stained with a drop of Lactophenol Cotton Blue and put on slides to be analyzed. Samples taken by the second method were treated by hot HCl and KMnO4 (Taylor et al. 2005) in order to obtain permanent slides. Light microscope observations and micrographs were made by Zeiss AxioImagerM.1 microscope with DIC optics (x1000 and x1600 magnification) and AxioVision 4.8 software.

The present study describes diversity of diatoms from the green frog skin. According to literature data no studies have been published on diatoms living on the frog skin.

Analysis of adhesive tape samples confirmed the presence of live diatom cells on the frog skin. Among them the most abundant were taxa from the genera Cocconeis, Epithemia, Gomphonema, Navicula and Rhopalodia. Presence of c. 30 diatom genera, such as Amphora, Craticula, Cymbella, Cymbopleura, Cymatopleura, Diploneis, Encyonema, Epithemia, Fallacia, Gomphonema, Luticola, Navicula, Neidium, Nitzschia, Pinnularia, Planothidium, Rhopalodia, Staurosira, Surirella, etc., was observed on permanent slides. The most dominant taxa were: Geissleria decussis sensu lato, Placoneis sp., Lemnicola hungarica, Cocconeis placentula var. lineate and Sellaphora bacillum.

We consider that the great diversity and abundance of diatoms is consequence of their transfer from the environment (mud and macrophytes from eutrophic ponds) onto mucous frog skin. Highly mucous skin is an excellent environment which enables primary conditions for the survival of diatoms. Future research, especially under laboratory conditions, could show whether the frog skin is permanent or temporary diatom habitat.
