Detection of antibodies against structural proteins of foot-and-mouth disease virus in bovines of western Uttar Pradesh, India.

Foot-and-mouth disease (FMD) is considered as one of the most important contagious viral diseases affecting cloven-footed animals. For effective control of FMD, immunization along with herd immunity is essential in the field conditions. To assure and track the coverage and effectiveness of the vaccination program, the serological studies are very much required after the vaccination program. The present study was aimed to investigate the prevalence of antibodies against structural proteins of FMD virus (FMDV) serotypes of O, A and Asia-1 in seven districts of western Uttar Pradesh, India, and assure the efficacy of vaccination under National Animal Disease Control Program. A total of 308 sera samples were collected from apparent healthy vaccinated cattle and buffaloes from seven districts including Amroha, Baghpat, Bareilly, Bulandsahar, Gautam Budh Nagar, Meerut and Muzaffarnagar of western Uttar Pradesh, India. Determination of antibodies against structural proteins of FMDV was carried out using solid-phase blocking enzyme-linked immunosorbent assay. The protective level of the FMDV serotypes O, A and Asia-1 included in the inactivated trivalent vaccine was 66.55, 48.05 and 47.08% in bovines, respectively. To provide the higher level of protection against the circulating FMDV, the present study recommended the thorough investigation of the immunogenic interaction between the vaccine strains and the field strains. Further investigations should also be conducted with larger sample size and across diverse geographical regions to gain a more comprehensive understanding of herd immunity.

Complete Genome Sequence of Brucella abortus 2308, Isolated from an Abortion Storm on a Dairy Farm in India.

The present report communicates the first complete genome sequence of Brucella abortus strain 2308, isolated from an abortion storm on a dairy farm in India. Bacteria were isolated in pure culture from the placentas of aborted calves, and next-generation sequencing (NGS) revealed that the genome sequence length of the isolated strain is 3,285,606 bp, with a GC content of 57.25%, an N50 value of 296,426 bp, and an L50 value of 4, containing 3,119 coding DNA sequences (CDSs), 49 tRNAs, 1 transfer-messenger RNA (tmRNA), and 3 rRNA genes.
