The present invention is directed to a method of treating poultry hatchlings in a hatchling tray. The method comprises of providing a soft gel form capable of being dispensed through a spray nozzle, providing a spray dispensing apparatus, the apparatus being capable of delivering a predetermined volume of the gel as a plurality of small beadlets through a plurality of nozzles, placing the hatchling tray containing the hatchlings beneath the nozzles of the dispensing apparatus, dispensing the predetermined volume of the soft gel containing the therapeutic agent as small beadlets into the hatchling tray and allowing the hatchlings to consume the beadlets. The present invention is also directed to a dispensing apparatus for dispensing a therapeutic agent in a soft gel into a hatchling tray of poultry hatchlings.

Use of synthetic peptides derived from Trypanosoma cruzi antigens and their use in vaccination against trypomastigote infection and Chagas disease. T. cruzi uses several surface proteins to invade the host. In their role of protection, the surface protients ensure the targeting and invasion of specific cells or tissues. A conserved region in the family of mucin-associated surface proteins (MASP) was used to analyze the expression of MASP at different points of invasion and proved to be important for host cell invasion, thus suggesting MASP as a candidate for vaccine development. A synthetic peptide, MASPsyn, was studied and showed efficacy in stimulating antibody and cytokine production necessary for resistance against the parasite.

The invention provides compositions and methods for preventing or reducing the severity of malaria.

Disclosed herein are expression vectors suitable for transfection in amoebas. The vectors may include a promoter from a protein-encoding gene from an amoeba, a selection marker, and a polynucleotide sequence encoding a polypeptide of interest, operably linked to the promoter. The promoter may be from the ACT1 gene from Naegleria fowleri.
