A compilation of the ciliate epibiont species (Ciliophora) found on marine and fresh water cnidarians has been carried out based on published records. The checklist includes the taxonomic position of each species of epibiontic ciliate, the species of basibiont cnidarians, the geographic zones and the bibliographic references where they were recorded. Cnidarians, especially colonial sessile forms, represent suitable substrates for numerous sessile and vagile ciliates. Altogether 79 ciliate species belong to five classes viz. Spirotrichea, Heterotrichea, Phyllopharingea, Suctorea and Oligohymenophorea were listed. The most diverce as epibions on cnidarians are representatives of Suctorea with 41 species and Peritrichia (under the class Oligohymenophorea) with 25 species. Three species belong to class Spirotrichea, four Heterotrichea and one Phyllopharingea. Among the other representatives (except Peritrichia) of class Oligohymenophorea, four species belong to subclass Scutucociliatia, one species each in subclass Hymenostomatia and Apostomatia. One suctorian species Ophryodendron abietinum and two species of peritrichs, Cothurnia cordylophora and Rhabdostyla sertularium one Heterotrichea Halofolliculina corallasia and one Scutucociliatia Philaster guamensis are likely specific to cnidarian hosts only.

Unlabelled: Streptolysin O (SLO) is a virulence determinant of group A (), the agent of streptococcal sore throat and severe invasive infections. SLO is a member of a family of bacterial pore-forming toxins known as cholesterol-dependent cytolysins, which require cell membrane cholesterol for pore formation. While cholesterol is essential for cytolytic activity, accumulating data suggest that cell surface glycans may also participate in the binding of SLO and other cholesterol-dependent cytolysins to host cells.

Human landscape modification is amongst the greatest drivers of biodiversity loss. Measuring faecal glucocorticoid metabolites (FGM) in wildlife is of great value to measure the impact of human activities on local biodiversity because FGM offer a non-invasive way of measuring an animal's response to changes in its environment in the form of adrenocortical activity. Here, we measure the concentration of FGM in three native Australian mammal species belonging to different trophic levels: the Tasmanian devil () and the spotted-tailed quoll (), both carnivores, and an omnivore that is primarily an arboreal folivore, the brushtail possum (), and compare the FGM concentrations across three major land uses: agricultural, plantation and National Parks.

Tonoplast intrinsic proteins (TIPs) are the channel-forming proteins predominantly found in the tonoplast of plant cells. Despite the identification of TIPs in numerous plant species, very less is known about the precise role of different TIP subgroups. In the present study, two genes belonging to the TIP3 subgroup were studied to understand tissue-specific role and solute transport activity.

Background: Technological development has led to the wide use of mobile phones. However, the role of the hand-held device in the possible spread of antibiotic-resistant bacterial pathogens considering gender variation, especially among Nigerian undergraduates is poorly understood. This study aimed to assess bacterial isolates recovered from male and female mobile phones for antibiotic resistance and determine possible factors that could facilitate their spread.

Known for its remarkable diversity and ecological importance, the fungal kingdom remains largely unexplored. In fact, the number of unknown and undescribed fungi is predicted to exceed the number of known fungal species by far. Despite efforts to uncover these dark fungal taxa, we still face inherent sampling biases and methodological limitations.
