Buccal Swab as a Source of Noninvasive Technique for Genomic DNA Collection in Felidae
This study was conducted to determine whether buccal cells obtained by swabbing could be a DNA source for genetic analysis, and to compare two preservative media, distilled water and Tris-EDTA (TE), pH 8.0. Buccal cell samples were collected from 30 domestic cats (Felis catus), 4 captive fishing cats (Prionailurus viverrinus) and 8 captive tigers (Panthera tigris). The total concentration of DNA and purity were not statistically different between the preservative media. All samples could be graded as a minimum as high quality DNA (DNA found with A260/A280 ratio >2.0 or < 1.8). In addition, the quality of DNA extracted from both media was successfully amplified for PCR. However, when compared to whole blood samples, total DNA concentration from buccal swab was significantly lower (p < 0.05) .Despite the decrease in DNA yield, buccal swab could be an alternative source for obtaining DNA for genetic analyses. This non-invasive, simple and inexpensive technique eases genetic studies in this family especially in domestic cat from which whole blood samples are difficult to collect.
