ABSTRACT A presumptive chromosomal cephalosporinase (pI, 9.0) from a clinical strain of Acinetobacter genomic species 3 (AG3) is reported. The nucleotide sequence of this β-lactamase shows for the first time the gene encoding an AmpC enzyme in AG3. In addition, the biochemical properties of the novel AG3 AmpC β-lactamase are reported

16Srrna Gene

Bangana dero is an economically important indigenous cyprinid fish of Manipur, India having maximum standard length of 40cm. For the taxonomic placement of this species among the Labeonin fishes, molecular characterization is conducted by using mitochondrial 16SrRNA gene sequences. Partial sequences of mito. 16SrRNA gene of fifteen cyprinid species of the sub-family Labeoninae were downloaded from NCBI Genbank. The analysed nucleotide sequence lengths were 538 bp. In a total of 811 characters, 194 were conserved sites (monomorphic) and 347 were variable sites (polymorphic) and out of 347 variable sites, 73 were parsimony informative sites and 274 singleton sites. The nucleotide frequencies are 31.4% (A), 22.57% (T), 24.00% (C) and 21.96% (G). The transition/transversion bias (R) is 2.51. The overall mean distance is 0.083. The dendogram constructed by Neighbour-Joining tree have three clusters which can indicate the taxonomic positions of Bangana dero .

Negative Mutant

An atypical urease-negative mutant of Actinobacillus pleuropneumoniae serovar 2 was isolated in Japan. Nucleotide sequence analysis of the urease gene cluster revealed that the insertion of a short DNA sequence into the cbiM gene was responsible for the urease-negative activity of the mutant. Veterinary diagnostic laboratories should be watchful for the presence of aberrant urease-negative A. pleuropneumoniae isolates.
