“…In this study, the disease with the highest seropositivity in the individuals evaluated was BoHV-1. Seroprevalences ranging from 35.65% to 73.13% are reported in Colombia [ 14 – 18 ]. On the other hand, diagnosis by serology for Neospora indicated that 51.1% of the cattle evaluated were seropositive, and these results are similar to national-level seroprevalences ranging from 2.8% to 57.5% [ 15 , 19 – 26 ].…”

The productivity of cattle farms is affected by infectious and noninfectious factors that generate economic losses and cause reproductive failure represented by low conception rates, embryonic mortality, abortions, and fetal mummification. The infectious agents that most impact the reproductive health of the bovine species from conception to birth are bovine herpesvirus type 1 (BoHV-1) causing infectious bovine rhinotracheitis (IBR), bovine viral diarrhea virus (BVDV), bovine parainfluenza virus type 3 (PI3), Neospora caninum and Leptospira spp. The objective of this study was to diagnose the presence of BoHV-1, bovine viral diarrhea (BVD), PI3, Neospora caninum, and Leptospira spp. by serology and identify the risk factors associated with infectious agents of reproductive interest in bovines of Boyacá (Colombia). A descriptive cross-sectional study was developed, with simple random sampling, where a sample size of 601 female cattle of Holstein, Jersey, and Normande breeds of different age groups was determined. Blood samples were taken and processed using the indirect ELISA technique (SYNBIOTICS®, SERELISA® BVD p80 Ab Mono Blocking, Ingezim R.12.NC.K, PRIMACHECK VPI-3®) and the MAT test for the diagnosis of bovine leptospirosis. The data were processed with the statistical program Epi Info™. The highest apparent seroprevalence was established for infectious bovine rhinotracheitis (61.1%), followed by BVD (37.6%), PI3 (40.9%), neosporosis (51.1%), and leptospirosis (14.8%). Variables such as age >4 years and Holstein breed for IBR and >4 years for BVD were established risk factors. Considering our results, we suggest implementing prevention and control plans that include vaccination as a prophylactic measure and biosecurity tools that reduce the probability of contagion and transmission of pathogens.

Seroprevalence and risk factors associated with bovine herpesvirus 1 in dairy herds of Colombia

Background and Aim: Infectious bovine rhinotracheitis (IBR) is an infectious disease widely distributed globally and is considered the main cause of various reproductive and respiratory tract diseases in cattle and buffaloes. This study aimed to estimate seroprevalence and determine risk factors associated with the presentation of IBR in the municipality of Sotaquirá, Boyacá (Colombia). Materials and Methods: A descriptive cross-sectional study with simple random sampling was performed, and the sample size was 1,000 cattle. Blood samples were obtained by coccygeal venipuncture and processed through indirect enzyme-linked immunosorbent assay using the Synbiotics® kit (Zoetis, New Jersey, USA) with a sensitivity and specificity of 96% and 98%, respectively. Data were processed using the statistical program EpiInfo® (Centers for Disease Control and Prevention; Atlanta, Georgia). Results: A high seroprevalence of 57.5% was established. Seroprevalence was the highest in cattle >4 years of age (65.0% apparent seroprevalence [AS]; 67% true seroprevalence [TS]) and in the Holstein breed (65.5% AS; 67.8% TS). The breed and age of the animals were significantly associated with each other. The Holstein breed, age group >4 years, uncertified semen, and fetal death were established as risk factors for IBR. In comparison, the age groups of <1 and 1–2 years and the Normande breed were established as protective factors against the bovine herpesvirus-1 virus. Conclusion: Management factors, such as livestock from other owners and animal purchases, which affect disease presentation, are evident. The implementation and development of novel prevention and control measures for IBR at the national level are necessary.

Seroprevalence and associated factors of viral agents of the bovine respiratory disease complex in buffaloes of Colombia

et al. 2022

The bovine respiratory disease complex causes sizable losses for livestock producers. Its presentation involves the interaction among multiple viral and bacterial pathogens. Viral agents include: bovine viral diarrhea virus (BVDV), bovine alphaherpesvírus 1 (BoHV-1), bovine parainfluenza virus (bPI3v) and bovine respiratory syncytial virus (BRSV); so far, these viruses have been little studied in the buffalo population. This study is aimed to assess the presence of these viruses in buffalo populations of the department of Córdoba, Colombia. A transversal study was conducted upon assessment of 37 farms and 861 buffaloes. Seroprevalence in animals were as follows: 21.7% (BVDV), 51.5% (BoHV-1), 73.6% (bPI3v) and 58.9% (BSRV), while seroprevalence in farms stood at: 94.6% (BVDV), 100% (BoHV-1), 100% (bPI3v) and 100% (BSRV). Conversely, the multiple seropositivity in buffaloes or past coinfection of viral agents amounted to 23.3% for a single virus, 31.8% for two viruses, 29.4% for three viruses and 7.1% for four viruses; only 8.4% of buffaloes were seronegative for four viruses. This is the first regional epidemiological study in the buffalo populations of Colombia and the results showed viral circulation and multiple seropositivity in animals; in addition, the high prevalence found pose a concerning epidemiological threat.
