“…In the case of BVDV other authors found a prevalence of 14%, whereas our study found that 11.3% of the analyzed samples were positive. Differences in prevalence between studies could be explained by aspects such as regions, diagnostic techniques, production systems, herd size, and handling practices (17).…”

Bovine respiratory disease (BRD) is the main reason for economic loss in feedlots. A cross-sectional study was conducted in order to detect the pathogens involved in BRD. A total of 88 animals with respiratory signs were sampled for diagnosis using PCR. The detected pathogens were bovine respiratory syncytial virus (80.6%), Mannheimia haemolytica (79.5%), Pasteurella multocida (68.1%), parainfluenza 3 virus (23.8%), bovine herpes virus-1 (20.4%), and bovine viral diarrhea virus (11.3%). The average number of treatments applied per animal was 1.3 with an estimated treatment cost of 16 USD per treatment/animal. Animals receiving more than one treatment averaged costs exceeding 38 USD per animal. In total, 77% of all animals received the first treatment during the first 3 weeks after arrival. We found a relationship between shrink percentage and the distance traveled by the livestock from its origin to the feedlot (P = 0.049). BRD represents a costly condition for feedlot operations. It is imperative that cattleman and veterinary practitioners recognize the necessity to apply additional preventive medicine strategies to reduce the impact of BRD. Preconditioning and a more systematic use of methaphylaxis may improve our ability to accurately identify the most effective strategies to reduce the impact of BRD.

La prevalencia (PRE) de anticuerpos contra diarrea viral bovina (DVB) se determinó en 421 vacas de 24 ranchos ubicados en 11 municipios de los estados de Puebla, Veracruz y Tabasco, México. Adicionalmente, se evaluó la influencia de anticuerpos contra DVB sobre la tasa de gestación (TG). Antes del estudio, los hatos nunca fueron vacunados contra DVB. Se obtuvieron muestras de sangre de cada vaca dos veces, con un intervalo de 3.5 a 4.0 meses. La presencia de anticuerpos se determinó mediante la técnica de ELISA. Al primer muestreo, Puebla (51.4 %) y Tabasco (49.7 %) presentaron menor PRE (P<0.01) que Veracruz (76.2 %); sin embargo, al segundo muestreo, los tres estados presentaron diferentes (P<0.05) PRE: 31.1, 54.6 y 76.0 %, respectivamente. Al primer muestreo, la PRE varió de 25.0 a 85.0 % entre municipios, mientras que al segundo varió de 15.0 a 85.9 %. Al primer muestreo, la PRE varió de 9.1 a 95.0 % entre ranchos, mientras que al segundo varió de 5.0 a 95.0 %. La TG de las vacas sin anticuerpos contra DVB fue similar (P>0.05) a la de las vacas con anticuerpos (57.3 vs 53.5 %). En conclusión, 1) Veracruz presentó mayor PRE que Puebla y Tabasco; 2) el 100 % de los hatos presentaron anticuerpos contra DVB, lo que sugiere que el virus de la DVB está ampliamente distribuido en los tres estados; 3) existió una gran variación en la PRE entre ranchos y entre municipios, siendo ésta cercana a 100 % en varios casos; y 4) la presencia de anticuerpos contra DVB no influyó la tasa de gestación.

“…Bovine viral diarrhea virus (BVDV) is an important viral pathogen of cattle that has spread globally and that causes significant economic loss to both dairy and beef cattle [1]. BVDV causes thousands and up to tens of millions of dollars of loss per calving interval [2] due to productivity and reproductive disorders in the herd [3]. Around 70-90% of infected cattle show no clinical signs [4-6].…”

Genetic analysis of NS5B gene from bovine viral diarrhea virus-infected cattle in Central and East Java, Indonesia

et al. 2019

Background and Aim: A previous study divided Indonesian bovine viral diarrhea virus (BVDV)-1 into subgenotypes BVDV-1a to BVDV-1d based on the partial NS5B gene using strain Bega as reference for BVDV-1a. In fact, it is clustered into BVDV-1c with strain Bega-like Australia. BVDV genotyping has been done on isolates from Jakarta, West and Central Java, but East Java isolates have not been genotyped. This study aimed to analyze genetic variability and amino acid residues in the nucleotide-binding pocket of the NS5B gene from infected cattle. Materials and Methods: Samples were obtained from the Sera Bank originating from active and passive surveillance of cattle that had been tested for BVDV antigen from 2013 to 2017. Detection of the p80 antibody and BVDV genotyping was carried out using ELISA and nested-multiplex-polymerase chain reaction (PCR), respectively. We defined 15 nested PCR products for partial sequencing of NS5B. Those field samples were selected from each location and year using proportional calculation as a representative sample. Homological and phylogenetic analyses of the partial NS5B gene were performed using BLAST and MEGA version 6. Results: Based on the phylogenetic tree analysis using 360 nucleotides as the partial NS5B gene, Indonesian BVDV-1 isolates from Central and East Java were subdivided to BVDV-1a (n=9), BVDV-1b (n=1), and BVDV-1c (n=5). In the present study, the homology of BVDV subgenotype -1a, -1b, and -1c was compared to the BVDV GenBank data and found 90-93%, 93%, and 92-95% respectively with the average pairwise distance of 0.207. A point mutation was shown at R283K of all BVDV isolates based on the sequence of three amino acid residues R283, R285, and I287 in the nucleotide-binding pocket as a part of the encoded RNA-dependent RNA polymerase. Conclusion: This study revealed the genetic variability of BVDV infecting cattle in Central Java and East Java, Indonesia, the subtypes BVDV-1a, BVDV-1b, BVDV-1c, and a point mutation at the R283K residue.
