In this study, 936 unvaccinated cattle sera were analyzed against five viruses: bovine viral diarrhea virus (BVDV), parainfluenzavirus type 3 (PIV-3), bovine adenovirus type 1 (BAdV-1), bovine adenovirus type 2 (BAdV-2) and bovine adenovirus type 3 (BAdV-3), which were caused by respiratory system diseases in cattle. The study used the serum neutralization (SN) test - a conventional method. The seropositive rates for each virus were found to be 20.19%, 41.02%, 23.82%, 21.90% and 8.1%, respectively. Evaluation of the data revealed that 25.64% of the sampled population was seronegative against the investigated viruses, 74.36% were seropositive for one or more of them and 42% of animals were found to be seropositive against any of the investigated viruses. 25.42% of the animals were seropositive against two viral infections whereas 5.23% of the animals were found to be seropositive against three viral infections and 0.1% of the animals were detected to be seropositive for four viruses.

A panel of four monoclonal antibodies (MAbs) was used to study the immunological profile of Rice yellow mottle virus (RYMV) genus Sobemovirus. Serological profiles of 35 representative isolates of RYMV from Borno, Gombe, Kaduna, Kano, Niger, Sokoto and Zamfara states in Northern Nigeria. All the RYMV isolates were classified into three major serogroups (SG1, SG2 and SG3) and further separated into six subgroups (Sg1a, Sg1b, Sg2a, Sg2b, Sg3a and Sg3b). The results demonstrate a significant serological variability among RYMV isolates in Northern Nigeria. The hierarchical analysis of the serological profiles data revealed high viral load in Kano, Kaduna and Gombe states, these show they are suitable locations for strategic RYMV diagnostic and field epidemiological studies.
