Development of a sensitive competitive enzyme-linked immunosorbent assay for serodiagnosis of Burkholderia mallei, a Tier 1 select agent.

Glanders is a highly contagious and potentially serious disease caused by Burkholderia mallei, a Tier 1 select agent. In this study, we raised a monoclonal antibody (mAb) against the lipopolysaccharide (LPS) of B. mallei and developed a competitive enzyme-linked immunosorbent assay (cELISA) for B.

Humoral antibody response of 10 horses after vaccination against African horse sickness with an inactivated vaccine containing all 9 serotypes in one injection.

Background: African horse sickness (AHS) is a devastating viral disease of equids that was first recorded in 1327. Currently, prevention and control of the disease are based on attenuated vaccines and midge control. It has been shown that attenuated Orbivirus vaccines are not always safe as they may reverse to virulence.

Camelids and Cattle Are Dead-End Hosts for Peste-des-Petits-Ruminants Virus.

Peste-des-petits-ruminants virus (PPRV) causes a severe respiratory disease in small ruminants. The possible impact of different atypical host species in the spread and planed worldwide eradication of PPRV remains to be clarified. Recent transmission trials with the virulent PPRV lineage IV (LIV)-strain Kurdistan/2011 revealed that pigs and wild boar are possible sources of PPRV-infection.

Evaluation of serological responses in horses challenged with Burkholderia pseudomallei using current diagnostic tests for glanders.

Six horses were challenged experimentally with a strain of Burkholderia pseudomallei isolated from a fatal case of the infection in a dromedary camel years earlier in the Emirate of Dubai. Three horses were inoculated subcutaneously and in 3 the bacterium was administered by the oral route. Four of the horses became serologically positive based on reactions to one or more of the OIE described tests for glanders.

Serodiagnosis of aspergillosis in falcons (Falco spp.) by an Afmp1p-based enzyme-linked immunosorbent assay.

Aspergillosis in falcons may be associated with high mortality and difficulties in clinical and laboratory diagnosis. We previously cloned an immunogenic protein, Afmp1p, in Aspergillus fumigatus and showed that anti-Afmp1p antibodies were present in human patients with A. fumigatus infections.
