Results showed that 1.96% of the histopathology samples corresponded to inflammatory processes typical of TB and that, in PCR, 4.25% of the samples had the amplification profile of the M. bovis species.

In Pakistan, livestock producers are importing commercially available vaccine of BoHV‑1, but no studies on the efficacy of these commercial vaccines against local isolates are available. Therefore, the present study was aimed to evaluate the efficacy of a commercially available vaccine of BoHV‑1 against local field isolates of virus. The rabbit model was used and the vaccine was evaluated for immunogenicity and protection after challenge with a highly virulent strain of a field virus. The immune response was measured by virus neutralization titers (VNT). This vaccine induced a humoral response in rabbits but that was not sufficient to completely protect the vaccinated animals against the wild‑type BoHV‑1 strain challenge. While a low virus titer compared to control rabbits was observed in the vaccinated rabbits (p<0.05), there was no sterilizing immunity or freedom from infection. However, complete freedom from disease, for example, the absence of pyrexia was noticed in the vaccinated group. In conclusion, the present study demonstrated that imported vaccine stock provoked only a partial protection against indigenous isolated of BoHV‑1.

Detection was done using antigen capture ELISA and RT‑PCR tests. In certain cases, animals with natural infection showed clinical signs and reproduction was also affected. Genetic characterization was performed considering the 5'‑UTR sequences of the bovine strains. In addition, the entire CSFV E2 genomic region could be amplified from two positive animals. The bovine strains were genetically related to the Chinese CSFV live attenuated hog cholera lapinized vaccine (HCLV) strain used in pigs, sharing sequence characteristics. The vaccine strain HCLV was widely used in China to protect bovines and yaks from bovine viral diarrhea, and, as a possible consequence, inducing an adaptation in cattle and a further natural diffusion. Furthermore, a contaminant strain from China was genetically distant from all other previously described genotypes of the CSFV.

Definitive control of human brucellosis requires control of brucellosis in livestock through practical solutions that can be easily applied to the field. In Italy, brucellosis remains endemic in several southern provinces, particularly in Sicily Region. The purpose of this paper is to describe the developed brucellosis model and its applications, trying to reproduce as faithfully as possible the complex transmission process of brucellosis accounting for the mixing of grazing animals. The model focuses on the contaminated environment rather than on the infected animal, uses real data from the main grazing areas of the Sicily Region, and aims to identify the best control options for minimizing the spread (and the prevalence) and to reach the eradication within the concerned areas. Simulation results confirmed the efficacy of an earlier application of the controls, showed the control should take place 30 days after going to pasture, and the culling time being negligible. Moreover, results highlighted the importance of the timing of both births and grazing pastures (and their interaction) more than other factors. As these factors are region‑specific, the study encourages the adoption of different and new eradication tools, tuned on the grazing and commercial behavior of each region.
