PROBLEM: The dog is considered the main domestic reservoir for Trypanosoma cruzi infection and a suitable experimental animal model to study the pathological changes during the course of Chagas disease (CD). Vaccine development is one of CD prevention methods to protect people at risk. Two plasmids containing genes encoding a trans-sialidase protein (TcSP) and an amastigote-specific glycoprotein (TcSSP4) were used as DNA vaccines in a canine model. Splenomegaly was not found in either of the recombinant plasmid-immunized groups; however, cardiomegaly was absent in animals immunized only with the plasmid containing the TcSSP4 gene. The inflammation of subendocardial and myocardial tissues was prevented only with the immunization with TcSSP4 gene. In conclusion, the vaccination with these genes has a partial protective effect on the enlargement of splenic and cardiac tissues during the chronic CD and on microscopic hearth damage, since both plasmids prevented splenomegaly but only one avoided cardiomegaly, and the lesions in heart tissue of dog immunized with plasmid containing the TcSSP4 gene covered only subepicardial tissue.

SOLUTION: Effect of the Plasmid-DNA Vaccination on Macroscopic and Microscopic Damage Caused by the Experimental Chronic Trypanosoma cruzi Infection in the Canine Model

Abd El-Hack). 21 (1952±28.82) did not significantly (p>0.05) improve growth performance compared to 41 the non-treated birds (NC and VC) (1970±19.56 and 1904±38.66). Essential oils 42 showed an antiviral effect on vNDv in vivo (in chickens) as a preventive measure 43 (PRV) as well as some therapeutic effect (TTT) through decreasing the viral shedding 44 titres (loNC 0 ), mortality rate, and severity of clinical signs and post mortem lesions, in 45 addition to serum malondialdhyde (MDA) level. Regarding the other viruses, the EOs 46 mixture did not improve the immune response to the AI and IB vaccines but age (2108±341.05). The studied EOs mixture showed an immune stimulating response 49 to ND and IBD vaccines, antiviral effect against ND virus especially if administered 50 before the challenge, however it did not have a growth promoting effect. 51 52

PROBLEM: Currently, there is no registered treatment for infections with emerging zoonotic coronaviruses like SARS-and MERS-coronavirus. We here report that in cultured cells low-micromolar concentrations of alisporivir, a non-immunosuppressive cyclosporin A-analog, inhibit the replication of four different coronaviruses, including MERS-and SARS-coronavirus. Ribavirin was found to further potentiate the antiviral effect of alisporivir in these cell culture-based infection models, but this combination treatment was unable to improve the outcome of SARS-CoV infection in a mouse model. Nevertheless, our data provide a basis to further explore the potential of Cyp inhibitors as host-directed, broad-spectrum inhibitors of coronavirus replication.

SOLUTION:
Alisporivir inhibits MERS-and SARS-coronavirus replication in cell culture, but not SARS-coronavirus infection in a mouse model
