Composition and diversity of 16S rRNA based skin bacterial microbiome in healthy horses.

Characterization of microbiota structure on the skin of healthy horses is important for further development of modulation strategies to ensure optimal bacterial composition for physiological processes. This requirement is also supported by the relatively high incidence of dermatological diseases in horses and thus the need to manage them therapeutically. The taxonomic analysis of skin samples (n = 30) from five different body parts of clinically healthy Shetlands ponies females (neck, back, abdomen, pastern, muzzle) kept under homogeneous conditions (in open stalls with paddock, feed with dry hay, green grass ad libitum and granulated feed) was performed using amplification of V3-V4 region of the 16S rRNA gene.

Virulence determinants and antibiotic resistance in staphylococci isolated from the skin of captive bred reptiles.

Knowledge of the composition and properties of skin microbiota in healthy reptiles is essential for preservation strategies and thus the prevention of skin dysbiosis leading to dermatological diseases. Despite the greatly increasing popularity of reptiles as pets, only a few studies have dealt with this topic. Therefore, the aim of this work was to analyse species composition of bacteria isolated from skin swabs of 40 reptiles (17 species) using MALDI-TOF spectrometry and to characterise the virulence properties of identified staphylococci (n = 51).

Antibacterial activity of plant-derived compounds and cream formulations against canine skin bacteria.

An urgent need to find alternative antimicrobial compounds effective in the prevention and treatment of skin infections led us to study the inhibitory activity of eight plant-derived bioactive compounds (betulin, curcumin, glycyrrhizic acid, guaiazulene, piperine, quercetin, quinine, tannic acid) against 14 canine skin isolates (11 Gram-positive and three Gram-negative bacteria) selected based on antibiotic resistance and virulence features. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were determined using the broth microdilution method. In detail, the results for the eight different plant compounds showed their inhibitory activity in the concentration range from 0.

Antimicrobial activity of organic acids against canine skin bacteria.

Canine skin is often a source of bacterial strains that are characterized by the presence of important virulence factors and a high antimicrobial resistance. These bacteria are involved in the pathogenesis of infectious skin diseases, which are very frequent in dogs. Moreover, canine skin isolates are easily spread to other animals and humans.

Distribution and Characterization of Staphylococci Isolated From Healthy Canine Skin.

Despite increasing interest to study skin microbiota with progressive methods, there are almost no data on staphylococcal species distribution on skin of healthy dogs available. Therefore we decide to characterize staphylococci isolated from 8 different body sites (inner pinna, chin, nasal skin, back, axilla, abdomen, interdigital area and perianal region) of healthy canine skin. A total of 91 staphylococci were isolated from 30 dogs living in East Slovakia.
