Abstract:
Staphylococcus aureus is a major pathogen for pyoderma in India. Phage pattern of bacteria gives valuable information in epidemiological studies of infection. Two hundred and two strains of Staphylococcus aureus isolated from pyoderma cases at Gorakhpur, were phage grouped and phage typed. It was found that 43.1 percent strains were not typable. Most common group was mixed phage group (23.8 percent) followed by phage group III (12.4 percent). Predominant phage types in mixed phage group was 84/81/85 and in phage group III was 84/85.
Insights
This study analyzed Staphylococcus aureus strains from Indian pyoderma cases. Most strains belonged to mixed phage groups or phage group III, aiding in infection epidemiology.
Area of Science:
- Microbiology
- Epidemiology
- Bacteriology
Background:
- Staphylococcus aureus is a significant cause of pyoderma in India.
- Bacterial phage typing is crucial for understanding infection spread and epidemiology.
Purpose of the Study:
- To phage group and phage type Staphylococcus aureus strains isolated from pyoderma patients in Gorakhpur, India.
- To identify prevalent phage groups and types within these isolates.
Main Methods:
- Isolation of 202 Staphylococcus aureus strains from pyoderma cases.
- Phage grouping and phage typing of the isolated bacterial strains.
Main Results:
- 43.1% of Staphylococcus aureus strains were untypable.
- The most common phage group was the mixed phage group (23.8%), followed by phage group III (12.4%).
- Predominant phage types identified were 84/81/85 in the mixed group and 84/85 in phage group III.
Conclusions:
- Phage typing revealed specific prevalent groups and types of Staphylococcus aureus in Indian pyoderma cases.
- A significant proportion of strains were untypable, highlighting potential challenges or unique characteristics in this population.
- The findings contribute valuable epidemiological data for Staphylococcus aureus infections in India.
