Insights

Healthy horses harbor diverse yeast-like fungi, with species varying by age and season. Candida and Saccharomyces were most common, highlighting the need for regular stable mycological monitoring.

Area of Science:

  • Veterinary Mycology
  • Equine Health
  • Microbial Ecology

Background:

  • Horses exhibit a high incidence of mycoses compared to other animals.
  • Yeast-like fungi can cause asymptomatic infections in horses, potentially leading to severe organ mycoses.
  • Carrier horses can act as vectors for transmitting fungal pathogens.

Purpose of the Study:

  • To identify yeast-like fungi and yeasts colonizing healthy horses.
  • To determine factors influencing the frequency of fungal pathogen isolation in horses.
  • To assess the taxonomic diversity of fungi in equine environments.

Main Methods:

  • Sampling of equine ontocenoses (mucosa and skin).
  • Isolation and identification of yeast-like fungi and yeasts.
  • Analysis of factors such as horse age and season on fungal prevalence.

Main Results:

  • Fungal colonization of equine mucosa and skin revealed a broad taxonomic spectrum.
  • Age influenced fungal isolation frequency and species diversity.
  • Seasonal variations were significant, with 37 species identified in autumn and 8 in spring.
  • Candida (12 species) and Saccharomyces (5 species) were prevalent genera.
  • Candida krusei and Saccharomyces cerevisiae were the most frequently isolated species.

Conclusions:

  • Equine mycobiota is diverse, with significant variations influenced by host age and environmental factors like season.
  • The study identified numerous fungal species previously unreported in horses, indicating a need for further research.
  • Routine mycological surveillance of stables is recommended to monitor potential pathogens and understand equine fungal ecology.

Fungal Phylum Ascomycota01:28

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
Microbes in Beverage Production01:25

Microbes in Beverage Production

Alcoholic beverages such as wine, beer, and spirits are the products of microbial fermentation processes that transform simple sugars into ethanol and a wide array of complex flavor compounds. These transformations rely on the metabolic activities of specific yeasts and bacteria, which are selected and controlled to yield the desired beverage characteristics.Wine Fermentation and MaturationWine production begins with the crushing of grapes to release juice and pulp, forming a must that is...
Fungal Group Zygomycota01:29

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
Overview of Fungi01:29

Overview of Fungi

Fungi are a diverse group of eukaryotes more closely related to animals than other eukaryotes. Fungal cell walls comprise chitin, a polysaccharide that provides structural strength, and glucans, which contribute to flexibility and integrity. Other polysaccharides, such as mannans and galactosans, may supplement or replace chitin in some fungi. These adaptations, along with their preference for acidic environments and tolerance for high osmotic pressure, enable fungi to thrive in various...
Microbial Fermentation01:23

Microbial Fermentation

Fermentation is a crucial anaerobic metabolic process that enables microbes to derive energy from sugar without relying on oxygen or an electron transport chain. This process is fundamental to various biological and industrial applications and is classified based on the metabolic products generated.Role of Pyruvate in FermentationPyruvate and its derivatives serve as key electron acceptors in fermentative pathways. The oxidation of NADH to regenerate NAD+ is essential for the continuation of...
Yeast Signaling01:28

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
