| Abstract The aerobic degradation of aromatic compounds by bacteria is performed by dioxygenases. To show some characteristic patterns of the dioxygenase genotype and its degradation specificities, twenty-nine gram-negative bacterial cultures were obtained from sediment contaminated with phenolic compounds in Wuhan, China. The isolates were phylogenetically diverse and belonged to 10 genera. All 29 gram-negative bacteria were able to utilize phenol, m-dihydroxybenzene and 2-hydroxybenzoic acid as the sole carbon sources, and members of the three primary genera Pseudomonas, Acinetobacter and Alcaligenes were able to grow in the presence of multiple monoaromatic compounds. PCR and DNA sequence analysis were used to detect dioxygenase genes coding for catechol... |

| ABSTRACT Gallibacterium anatis, a member of the Pasteurellaceae family, leads to decrease in egg-production, animal welfare and increase in mortality. This study aimed to diagnose G. Anatis, which caused economic losses in laying hens by using conventional and molecular techniques. In this study, G. anatis was examined from a total of 200 dead chicken tissues (heart, liver, lung, spleen and trachea) in laying hen farms that observed a decrease in egg production with respiratory system infection. Conventional methods based on colony morphology, sugar fermentation tests and hemolytic properties and molecular conformation using 16S rRNA-23S rRNA specific primers were performed to identify G. anatis. G. anatis was isolated in 20 (10%) of the examined samples... |
