abstract atrazine biodegradation by bacteria is one of the most important aspects of bioremediation. atrazine can be degraded by various species of bacteria. bacteria use atrazine as nitrogen and carbon sources. the aim of this study was to determine atrazine degradation by pseudomonas fluorescence and pseudomonas aeruginosa. the experiment consisted of two pseudomonas bacteria, three levels of...

Transit (conduction) times from the wrist to the seventh cervical spinous process (C7) were measured by using the F-wave response (TA) and the cervical somatosensory response (SEPC). The mean values obtained in 25 controls were 10.1 +/- 0.9 s-3 and 10.9 +/- 1.0 s-1 respectively. The 0.8 +/- 1.0 s-3 difference between the two methods represents central delay of SEPC, possibly at the level of the...

The in vitro susceptibilities of three Pseudomonas species (Pseudomonas aeruginosa, Pseudomonas putida, and Pseudomonas fluorescens) and Xanthomonas maltophilia to quinolone antimicrobial agents were determined. Several newer agents, particularly PD117558, PD117596, PD127391, sparfloxacin (AT-4140), A-56620, and temafloxacin, were active against Pseudomonas species. X. maltophilia isolates were...

The complete genome of the Pseudomonas aeruginosa bacteriophage PM105 is 39,593 bp long. The phage belongs to the B3 family of transposable Mu-like phages, as confirmed by the presence of bacterial DNA joined to the phage genome ends. PM105, together with other B3-like phages, form a newly arising species.

Fourteen quinolone-resistant Pseudomonas putida isolates were recovered from imported frozen shrimp sold in the United States. Two isolates harbored plasmids with qnrA and qnrB genes. PCR and DNA sequencing of quinolone resistance-determining regions identified novel substitutions in GyrA (His139→Glu and Thr128→Ala) and GyrB (Thr442→Asn, Gly470→Ala, and Ile487→Pro) and previously reported subst...
