Summary
Shigella infections are common in children, with frequent resistance to multiple antibiotics observed. This study highlights the prevalence of Shigella flexneri and Shigella sonnei strains and their antibiotic resistance patterns.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Shigella is a significant cause of bacterial dysentery, particularly in children.
- Antibiotic resistance in Shigella poses a growing public health threat.
- Understanding local resistance patterns is crucial for effective treatment.
Purpose of the Study:
- To characterize Shigella strains isolated from stool samples.
- To determine the prevalence of different Shigella species and serotypes.
- To assess the antibiotic resistance profiles of these strains.
Main Methods:
- Isolation and identification of Shigella strains from stool samples.
- Serotyping of Shigella isolates.
- Antibiotic susceptibility testing.
Main Results:
- A total of 447 Shigella strains were isolated between 1989-1991.
- Shigella flexneri (13.4%) and Shigella sonnei (65%) were the most common isolates.
- A high proportion of strains (34.4% to three, 40% to more than three antibiotics) exhibited multidrug resistance.
- Resistance to furazolidine and neomycin was also noted.
Conclusions:
- Shigella infections, especially Shigella sonnei and Shigella flexneri, are prevalent in the study population.
- High rates of multidrug resistance in Shigella strains necessitate careful antibiotic selection.
- Continuous surveillance of Shigella epidemiology and antibiotic resistance is essential.

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...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
