Summary
The stable fly (Stomoxys calcitrans) can carry various enterobacteria, including Shiga toxin-producing Escherichia coli. This research highlights potential public health risks associated with these common insects.
Area of Science:
- Microbiology
- Veterinary Entomology
- Public Health
Background:
- Stable flies (Stomoxys calcitrans) are significant pests in livestock production.
- Insects can act as vectors for various bacterial pathogens.
- Enterobacteriaceae pose risks to animal and human health.
Purpose of the Study:
- To determine the prevalence of enterobacterial agents on the external surface of stable flies.
- To investigate the presence of virulence genes in isolated enterobacteria.
Main Methods:
- Isolation and identification of bacterial species from external surfaces of Stomoxys calcitrans.
- Molecular detection of virulence genes (stx1, stx2, eae) in Escherichia coli isolates.
Main Results:
- Twenty different enterobacterial species were identified.
- Escherichia coli was the most frequently isolated species.
- Shiga toxin genes (stx1, stx2, and/or eae) were detected in 13.04% of E. coli isolates.
Conclusions:
- Stable flies harbor a diverse range of enterobacteria.
- The presence of Shiga toxin-producing E. coli on stable flies indicates a potential transmission route for pathogenic bacteria.
- Further research is warranted to assess the epidemiological significance of stable flies in pathogen transmission.

01:27Microbiota of the Large Intestine
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
01:27Microbiota of the Stomach and Small Intestine
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:18Surface Membrane Barriers
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:29Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
