Abstract
Salmonella species are Gram-negative bacteria with more than 2600 serovars. Among these serovars, many are associated with various diseases in livestock and humans. White Kauffman Le-Minor (WKL) serotyping scheme applies specific serum to determine the serovars of Salmonella. Recent studies have applied molecular methods for serovar predictions. These methods include PCR, hybridization and sequence data to detect/predict serovar-specific genetic elements. Among these, PCR is a robust method if the unique genetic element is already known. Within this context, also involving novel primers, two multiplex PCR assays were standardized to detect six important Salmonella serovars viz. Typhimurium, Enteritidis, Kentucky, Infantis, Virchow and Gallinarum associated with poultry in India. The developed PCR assays showed targeted serovar specificity. Serial dilution experiments of both kit-based and crude lysate DNA preparations indicated similar applicability of both methods for testing from pure cultures. Further the developed assays were validated with 25 recent field isolates to confirm the applicability in routine diagnosis. The PCR assay could predict all the targeted serovars (17/25) with 100% specificity (CI-95%; 0.63-1). Molecular serotyping can reduce the number of serum used incomparison to the conventional serotyping which involves more random application of serum.

A comparative genomics approach for identifying genetic factors in Escherichia coli isolates associated with bovine diseases. J Appl Microbiol 2022; 133:3490-3501.

Abstract
AIMS Escherichia coli are ubiquitously present bacterial pathogens that cause septicaemia, diarrhoea and other clinical illness in farm animals. Many pathogen factors can be associated with disease conditions. Currently, studies inferring E. coli genetic factors associated with infection in bovines are limited. Hence, the present study envisaged to determine the pathogen genetic factors associated with bovine disease conditions. METHOD AND RESULTS The comparative genomic analysis involved genome sequence data of 135 diseased and 145 healthy bovine origin E. coli strains. Phylogroups A and C, as well as pathotypes ExPEC and EPEC, were found to have a strong connection with bovine disease strains. STEC strains, including EHEC, seem to play a less important role in bovine disease. Sequence types (STs) predominant among strains from diarrhoeal origin were ST 301 (CC 165) and ST 342. Correlation of core genome phylogeny with accessory gene based clustering, phylogroups and pathotypes indicated lineage specific virulence factors mostly associated with disease conditions. CONCLUSIONS Comparative genomic analysis was applied to infer genetic factors significant in bovine disease origin E. coli strains. Isolates from bovine disease origin were enriched for the phylogroups A and C, and for the pathotypes ExPEC and EPEC. However, there was minimal evidence of STEC involvement. The study also indicated predominant genetic lineages and virulence genes (pap, sfa and afa) associated with disease origin strains. SIGNIFICANCE AND IMPACT OF STUDY;: The study revealed significant pathotypes, phylgroups, serotypes and sequence types associated with bovine disease conditions. These identified genetic factors can be applied for disease diagnosis, implementing vaccine and therapeutic measures. In addition, E. coli isolates from the bovine species revealed a complex pattern of disease epidemiology.

Abstract
Clostridium perfringens is a globally recognized zoonotic pathogen. We report isolation and genotyping of C. perfringens from neonatal calves, dairy workers and their associated environment in India. A total of 103 fecal samples from neonatal calves, 25 stool swabs from the dairy workers and 50 samples from their associated environment were collected from two dairy farms. C. perfringens was detected in 26 out of 103 (25.2%) neonatal calf samples, 7 out of 25 (28%) human stool samples and 17 out of 50 (34%) environmental samples. C. perfringens type A strains were predominant in neonatal calves (24/26; 92.3%) and associated environment (15/17; 88.2%). In contrast, strains from dairy workers mostly belonged to type F (5/7; 71.4%), which also carried the beta2 toxin gene. Seventeen strains were analyzed by multilocus sequence typing (MLST) for studying genotypic relationship along with 188 C. perfringens strains available from public databases. A total of 112 sequence types (STs) were identified from 205 C. perfringens strains analyzed. A Clonal complex (CC) represented by three STs (ST 98, ST 41 and ST 110) representing predominantly type F (18/20 strains) were mostly associated with human illnesses. Among predominant STs, ST 54 was associated with enteritis cases in foals and dogs and ST 58 associated with necrotic enteritis in poultry. Seventeen Indian strains were assigned to 13 STs. Genetic relatedness among strains of calves, dairy worker and associated environments indicate inter-host transfers and zoonotic spreads.

Abstract
Clostridium chauvoei causes blackleg disease in domestic animals, especially cattle and sheep. The pathogen produces several toxins including CctA - a hemolysin and protective antigen. Molecular pathogenesis of the disease is poorly understood, possibly due to lack of genetic manipulation tools for C. chauvoei. In the present study, we report the marker-less deletion of cctA gene using the CRISPR-Cas9 system. The C. chauvoei cctA deletion mutant had negligible hemolytic and significantly reduced cytotoxic activities. To the best of our knowledge, this is the first report of genetic manipulation of C. chauvoei. The method we used in this study can be applied for genetic manipulation of C. chauvoei to better understand the pathogenesis and genetics of the pathogen.

Abstract
Aim: Blackleg disease is caused by Clostridium chauvoei in ruminants. Although virulence factors such as C. chauvoei toxin A, sialidase, and flagellin are well characterized, hyaluronidases of C. chauvoei are not characterized. The present study was aimed at cloning and sequence analysis of hyaluronoglucosaminidase (nagH) gene of C. chauvoei. Materials and Methods: C. chauvoei strain ATCC 10092 was grown in ATCC 2107 media and confirmed by polymerase chain reaction (PCR) using the primers specific for 16-23S rDNA spacer region. nagH gene of C. chauvoei was amplified and cloned into pRham-SUMO vector and transformed into Escherichia cloni 10G cells. The construct was then transformed into E. cloni cells. Colony PCR was carried out to screen the colonies followed by sequencing of nagH gene in the construct. Results: PCR amplification yielded nagH gene of 1143 bp product, which was cloned in prokaryotic expression system. Colony PCR, as well as sequencing of nagH gene, confirmed the presence of insert. Sequence was then subjected to BLAST analysis of NCBI, which confirmed that the sequence was indeed of nagH gene of C. chauvoei. Phylogenetic analysis of the sequence showed that it is closely related to Clostridium perfringens and Clostridium paraputrificum. Conclusions: The gene for virulence factor nagH was cloned into a prokaryotic expression vector and confirmed by sequencing.

Abstract
AIM The present study was undertaken to clone, express and study the immunogenicity of P67 protein of Mycoplasma leachii. MATERIALS AND METHODS P67 gene was amplified from genomic DNA of M. leachii. The polymerase chain reaction (PCR) product was inserted in pRham N-His SUMO Kan vector and was used to transform competent Escherichia cloni 10G cells. Recombinant protein expression was done by inducing cells with 0.2% Rhamnose. Purification was done using nickel nitrilotriacetic acid affinity chromatography. Western blot and dot blot analysis were performed to assess the immunoreactivity of P67 protein. RESULTS PCR amplicon size of P67 gene was found to be 1500 base pair. The size of the fusion protein with SUMO tag was 79 kDa in sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis. The recombinant P67 fusion protein expressed in pRham N-His SUMO Kan vector was found to be immunogenic in both western blot and dot blot analysis. CONCLUSION Western blot and dot blot analysis of P67 protein of M. leachii revealed that the protein is immunogenic. Further work is needed to evaluate the role of P67 antigen of M. leachii as an immunodiagnostic agent.

Abstract
Pasteurella multocida causes acute septicemic and respiratory diseases, including haemorrhagic septicaemia, in cattle and buffalo with case fatality of 100%. In the present study, mice were infected with P. multocida (1.6 × 103 cfu, intraperitoneal) to evaluate host gene expression profile at early and late stages of infection using high throughput microarray transcriptome analyses. Several differentially expressed genes (DEGs) at both the time points were identified in P.multocida infected spleen, liver and lungs. Functional annotation of these DEGs showed enrichment of key pathways such as TLR, NF-κB, MAPK, TNF, JAK-STAT and NOD like receptor signaling pathways. Several DEGs overlapped across different KEGG pathways indicating a crosstalk between them. The predicted protein—protein interaction among these DEGs suggested, that the recognition of P. multocida LPS or outer membrane components by TLR4 and CD14, results in intracellular signaling via MyD88, IRAKs and/or TRAF6 leading to activation of NFκB and MAPK pathways and associated cytokines.

Abstract
Transferrin binding protein A (TbpA), an iron acquisition surface protein that also acts as virulence factor, is widely distributed among strains of Pasteurella multocida. In the present study, a total of seven clones of TbpA fragments (39D to F777; 39D to Q697; 188V to F777; 188V to Q697; 39D to P377; 188V to P377 and 39D to F187) belonging to P. multocida B:2 were constructed, over-expressed and purified as recombinant fusion proteins from Escherichia coli using affinity chromatography. Immunization of mice with rTbpA fragments resulted in a significant (p < 0.05) rise in antigen specific serum total IgG and subtypes (IgG1 and IgG2a) tires. All immunized mice challenged with 8 LD50 of P. multocida B:2 resulted in a variable protective efficacy up to 50%. The study indicated the potential possibilities to incorporate full length TbpA in subunit vaccine formulation composed of synergistic subunit antigens against haemorrhagic septicaemia (HS) in cattle and buffalo.

Abstract
Bluetongue virus (BTV) causes haemorrhagic disease in sheep and induces death in cultured mammalian cells. In the present study, BTV-induced apoptotic pathways in Vero cells were elucidated. Cells infected with BTV at 0.1 m.o.i underwent DNA fragmentation and membrane blebbing within 48 h postinfection. BTV-induced apoptosis was blocked by the pan-caspase inhibitor, z-VAD-FMK. Immuno-blotting using anti-caspase-8 and -9 antibodies detected the activation of the respective caspases. Flow cytometry analyses following 3, 3' dihexyloxacarbocyanine iodide staining revealed the loss of mitochondrial membrane potential. Our study confirms the involvement of both caspase-dependent extrinsic and intrinsic pathways of apoptosis in BTV-infected cells.

Abstract
Bluetongue, an arthropod borne viral disease of wild and domestic ruminants, causes heavy economic losses throughout the world. In the present study, full-length VP7 gene of Indian bluetongue virus (BTV) serotype 23 was sequenced and compared with prototype strains of BTV reported from different countries. Nucleotide sequence analysis of VP7 gene revealed Indian BTV serotype 23 to have 1154 nucleotides with the deletion of two nucleotides at 3' non-coding region and a unique amino acid change 211S-N. The Indian virus also demonstrated a maximum similarity of 94.2% with Australian serotype 1 and a minimum similarity of 67.4% with Australian serotype 15. However, at deduced amino acid level, it had maximum similarity of 99.7% and a minimum of 82.5% with Chinese serotypes 1, 2 and 4 and Australian serotype 15, respectively. Deduced amino acid sequence analysis of putative receptor binding domain (121-249) revealed all the nine hydrophilic domains to be conserved across the serotypes. Functional motifs present in VP7 protein were also conserved in almost all the BTV serotypes including Indian serotype 23. Phylogenetic analysis based on VP7 gene sequence revealed Indian BTV serotype 23 segregating into a monophyletic group along with Australian serotype 1 and Chinese serotypes 1, 2 and 4, indicating its close evolutionary relationship with these Australian and Chinese serotypes.
