First report of whole genome sequence of septicemic Pasteurella multocida serovar B:2 'Soron' strain isolated from swine.

Pig pasteurellosis, caused by Pasteurella multocida, is an acute infection that also has economic implications for pig farmers. We report the complete genome sequence of a P. multocida, serovar B:2 'Soron' strain isolated from the blood of a pig that had died of pasteurellosis in India.

Host responses and bacterial colonization following inoculation of Pasteurella multocida P strain into unvaccinated and aluminum hydroxide gel hemorrhagic septicemia vaccinated mice.

Hemorrhagic septicemia is a highly infectious and contagious disease caused by Pasteurella multocida serogroup B:2 in tropical Asian and African countries. The acute inflammatory responses induced by Pasteurella multocida are the main cause of death in hemorrhagic septicemia. Therefore, present study was undertaken to examine the blood cytokine expression profiles (TNF-α, IL-1β, and IL-6), bacterial colonization and histopathological changes of intraperitoneally and subcutaneously challenged vaccinated and unvaccinated mice with 10 CFU of P.

Classical swine fever in pigs: recent developments and future perspectives.

Classical swine fever (CSF) is one of the most devastating epizootic diseases of pigs, causing high morbidity and mortality worldwide. The diversity of clinical signs and similarity in disease manifestations to other diseases make CSF difficult to diagnose with certainty. The disease is further complicated by the presence of a number of different strains belonging to three phylogenetic groups.

Evaluation and comparison of native and recombinant LipL21 protein-based ELISAs for diagnosis of bovine leptospirosis.

A 21-kDa leptospiral lipoprotein (LipL21) was evaluated for its diagnostic potential to detect bovine leptospirosis by ELISA. Both native LipL21 (nLipL21) and recombinant LipL21 (rLipL21) proteins were tested and compared regarding diagnostic efficiency, and no statistically significant difference was observed. The sensitivity of rLipL21 ELISA for 62 microscopic agglutination test (MAT) positive sera was 100% and the specificity with 378 MAT negative sera was 97.

Molecular characterization of Indian rabies virus isolates by partial sequencing of nucleoprotein (N) and phosphoprotein (P) genes.

Rabies is endemic and an important zoonosis in India. There are very few reports available on molecular epidemiology of rabies virus of Indian origin. In this study to know the dynamics of rabies virus, a total of 41 rabies positive brain samples from dogs, cats, domestic animals, wildlife, and humans from 11 states were subjected to RT-PCR amplification of N gene between nucleotide N521-N1262 (742 bp) and P gene between nucleotide P239-P750 (512 bp).

Cloning and molecular characterization of outer membrane protein A (ompA) gene from Mycobacterium bovis.

The ompA gene, 981 bp in size and identified in the Mycobacterium bovis genome, was cloned and sequenced. Predicted amino acid sequences showed a protein of molecular weight 33.5 kDa with an isoelectric point of 7.

Occurrence of RD9 region and 500 bp fragment among clinical isolates of Mycobacterium tuberculosis and Mycobacterium bovis.

The present investigation dealt with the identification of Mycobacterium tuberculosis and M. bovis by RD9 region and 500 bp fragment PCR assays. Eight M.

Random amplified polymorphic DNA (RAPD) analysis of Mycobacterium tuberculosis strains in India.

The usefulness of random amplification of polymorphic DNA (RAPD) analysis for typing Indian strains of M. tuberculosis was investigated. M.

Detection of Mycobacterium avium & M. tuberculosis from human sputum cultures by PCR-RFLP analysis of hsp65 gene & pncA PCR.

Background & Objective: Identification of mycobacteria by conventional methods is slow, labour intensive and may at times fail to produce precise results. Molecular techniques developed in the recent past, overcome these disadvantages facilitating rapid identification of most species. We undertook this study to characterize mycobacteria isolated from sputa of human patients suspected to have tuberculosis by conventional methods and later, by polymerase chain reaction-restriction fragment length polymorphism analysis (PRA) of hsp65 gene and pncA PCR.

Rapid differentiation of Mycobacterium bovis and Mycobacterium tuberculosis based on a 12.7-kb fragment by a single tube multiplex-PCR.

The aim of this work was the design and validation of a rapid and easy single tube multiplex-PCR (m-PCR) assay for the unequivocal differential detection of Mycobacterium bovis and Mycobacterium tuberculosis. Oligonucleotide primers were based on the uninterrupted 229-bp sequence in the M. bovis genome and a unique 12.

Molecular fingerprinting of clinical isolates of Mycobacterium bovis and Mycobacterium tuberculosis from India by restriction fragment length polymorphism (RFLP).

Forty mycobacterial strains comprising clinical Indian isolates of Mycobacterium tuberculosis (28 field isolates +1H37 Rv) and Mycobacterium bovis (10 field isolates +1 AN5) were subjected to restriction fragment length polymorphism analysis (RFLP) using IS6110 and IS1081 probes. Most of these strains originated from dairy cattle herd and human patients from Indian Veterinary research Institute (IVRI) campus isolated from the period of 1986 to 2000. Our study showed presence of 8 copies of IS6110 in most of the M.

A multiplex-PCR for the differentiation of Mycobacterium bovis and Mycobacterium tuberculosis.

A multiplex-polymerase chain reaction (PCR) assay based on one-step amplification and detection of two different mycobacterial genomic fragments was designed for differentiation of Mycobacterium bovis and Mycobacterium tuberculosis. The oligonucleotide primers were chosen from a 500-bp genomic fragment which is well conserved in M. bovis and the pncA gene (based on M.
