Table 4 Efficacy of oral gram-positive and gram-negative bacteria for DNA-based identification
From: Recent advancements in identification and detection of saliva as forensic evidence: a review
Type of bacteria | Heat (40–80 °C) denaturation | Microbial decomposition (1–5 days) | UV irradiation (0.01–1 J/cm2) |
|---|---|---|---|
Gram-positive bacteria (Streptococcus salivarius and Streptococcus oralis) | Detected | Detected (5-day sample) | Detected (> 50%) |
Gram-negative bacteria (Veillonella atypica and Prevotella maculosa) | Detected | Detected (1-day sample) | Not detected |
