ncbi.nlm.nih.gov) probably corresponds to the bacterial chromosome (Figure 2). Two other replicons each less than 1 Mb were also seen in the PFGE pattern which makes it possible to classify isolates into two groups. One group comprises mosquito isolates no. 127 and no. 131 with the reference strain Pantoea stewartii (CFBP 3614), another group included
mosquito isolates no. 95 and no. 110 with the reference strain Pantoea agglomerans (CFBP 4740) while all other mosquito isolates have patterns closely related to each other but distinct from the reference strains. When the Eckhardt procedure for plasmid analysis was used, high-molecular-weight plasmids (from 75 kb up to 980 kb) from Pantoea mosquito isolates were detected. The number https://www.selleckchem.com/products/BI-2536.html (from 2 to 6) and size of plasmids were different from those observed in reference strains (Figure 3). If classified according to plasmid content, mosquito isolates no. 127 and no. 131 showed unique patterns that
Torin 1 datasheet were similar to each other, while the other mosquito isolates clustered into two distinct groups. The first group included 6 isolates (nos. 85, 86, 93, 95, 104 and 124) and the second group contained 3 isolates (nos. 110, 111 and 115) (Figure 3). Using another method to detect lower-molecular-weight plasmids (less than 28 kb), two supplementary plasmids were detected in mosquito isolates no. 127 and no. 131 only, around 8 and 15 kb (data not shown). Figure 2 PFGE of undigested genomic DNA of Pantoea mosquito isolates and their reference strains. Chromosomal
DNA from Hansenula wingei was used as a reference (BioRad). Characteristics of the samples are indicated in Table 3. Figure 3 Electrophoretic profiles of high-molecular-weight plasmids from Pantoea mosquito isolates obtained using a modified Eckhardt procedure. Plasmids from Azospirillum brazilense strains En-Ab79 and Sp245 were used as references [38, 39]. Characteristics of the samples are indicated in Table 3.
