Demonstration Of Immunity Research Articles

The early history of dengue in Australia.

Although reports of outbreaks of dengue-like diseases in the Asia Pacific region were frequent from about 1870, the disease probably did not become endemic in Australia until about 1885. Several seminal discoveries about this disease were made in Queensland and later in Sydney. These included a refined case definition for dengue, identification of the mosquito vector, demonstration of a viraemia and its duration, quantification of the incubation time, demonstration of immunity after experimental infection and recognition that the virus could cause a fatal haemorrhagic fever, and this was more frequent in second or subsequent infections. Australian research was foundational to the modern understanding of dengue.

Demonstration of immunity against isospora suis in swine

Piglets naturally exposed or experimentally infected with Isospora suis oocysts were given challenge doses of oocysts to determine the extent of development of immune resistance. Piglets in both studies shed low numbers of, or no detectable oocysts, following challenge. Administration of methylprednisolone acetate failed to induce oocysts shedding in previously infected piglets. Piglets rechallenged with I. suis following steroid injections also failed to shed significant numbers of oocysts suggesting development of immunity to reinfection.

Systemic anaphylaxis in the human being.

THE term "anaphylaxis" was introduced by Poitier and Richet1 to describe the profound shock with subsequent death produced in some dogs upon reinjection of the poison of the sea anemone. The occurrence of a fatal response to repeat injection rather than a demonstration of immunity or prophylaxis to the foreign protein prompted the designation anaphylaxis. The clinical manifestations of the anaphylactic syndrome are entirely due to the action of diverse chemical mediators released with great rapidity by antigen activation of a discrete number of target cells previously sensitized by interaction with antibody; the chemical mediators — histamine, slow reacting substance . . .
