Effective oral immunization systems may be very helpful to the salmon industry, particularly during the seawater growth stages in which vaccination through injection is not possible. During the seawater growing stage, fish become more susceptible to several types of disease, due to the natural decay of vaccine-induced immune responses. In this study, we demonstrate the immune response and effic...

Ebolavirus and Marburgvirus (belonging to the Filoviridae family) emerged four decades ago and cause epidemics of haemorrhagic fever with high case-fatality rates. The genome of filoviruses encodes seven proteins. No significant homology is observed between filovirus proteins and any known macromolecule. Moreover, Marburgvirus and Ebolavirus show significant differences in protein homology. The...

Plasvacc Australia (Plasvacc) 6066 Cunningham Hwy Kalbar Queensland Australia 4309 61-7-54637600 Objectives – To develop an effective Escherichia coli (E. coli) vaccine that engenders a strong and measurable humoral response in canine plasma donors.

Pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. A polymerase chain reaction (PCR) assay was developed using primers derived from conserved part of 16S-23S rRNA gene. The PCR amplified a fragment size of 0.7 kb using DNA from nine avian P. multocida  isolates...

Meningococcal septicaemia has high mortality, especially when the diagnosis is delayed or missed. Early recognition is not always straightforward, as classic clinical features may be absent or overlooked at initial presentation. Septicaemia without focal infection accounts for 15%-20% of cases of meningococcal disease and is the most worrisome manifestation in terms of diagnosis and outcome; in...
