Abstract:
Burkholderia mallei and B. pseudomallei are causative agents of glanders and melioidosis, respectively, i.e. severe and fatal infection diseases of man and animal. The computer-based analysis of the 23S rRNA gene sites was used for selecting the primers. Two pairs of primers were chosen for the identification of B. mallei and Bpseudomallei. DNAs from 48 B. pseudomallei and 15 strains of B. mallei, unlike from other geterological bacteria, were positively amplified. Therefore, the method of polymerase chain reaction can be used in laboratory diagnosis of glanders and melioidosis.
Insights
This study identifies Burkholderia mallei and Burkholderia pseudomallei using specific primers. The polymerase chain reaction method offers a reliable laboratory diagnosis for glanders and melioidosis in humans and animals.
Area of Science:
- Microbiology
- Molecular Biology
- Infectious Diseases
Context:
- Burkholderia mallei and B. pseudomallei cause glanders and melioidosis, respectively.
- These are severe, fatal zoonotic diseases affecting humans and animals.
- Accurate and rapid diagnostic methods are crucial for disease control.
Purpose:
- To develop and validate a polymerase chain reaction (PCR) assay for the specific identification of B. mallei and B. pseudomallei.
- To utilize computer-based analysis of 23S rRNA gene sequences for primer selection.
Summary:
- Computer-aided analysis of the 23S rRNA gene identified two primer pairs specific for B. mallei and B. pseudomallei.
- DNA from 48 B. pseudomallei strains and 15 B. mallei strains were successfully amplified.
- No amplification was observed with DNA from other bacterial species, indicating high specificity.
Impact:
- The developed PCR method provides a sensitive and specific tool for the laboratory diagnosis of glanders and melioidosis.
- This can aid in early detection, treatment, and containment of these dangerous infections.
- Facilitates accurate differentiation between B. mallei and B. pseudomallei, crucial for epidemiological studies and public health interventions.
