Studies of biological properties of newborn larvae of Trichinella spiralis and immune responses against newborn larvae in the host are reviewed. The biological properties of newborn larvae examined are the natural production, migration, surface antigens and their maturity and effects on the host. Various mechanisms of host immunity to newborn larvae are reviewed, including the stage specificity...

The kinetics of anti-T. spiralis newborn larvae (NBL) immunity and its dose effects were studied in vivo. Rats were either immunized with newborn larvae i.v. or muscle larvae per os and challenged with newborn larvae either i.v. or i.p. on day 7 up to day 27 after immunization. Immunity was assessed by examining the muscle larvae burden or the larval recovery from the peritoneal cavity. Recover...

The innate immune response is the first line of defense against microbial infections. Innate immunity is made up of the surface barrier, cellular immunity and humoral immunity. In newborn, immunologic function and demands are different to adults. Neonatal innate immunity specifically suppresses Th1-type immune responses, and not Th2-type immune responses, which are enhanced. And the impaired re...

Tumors were induced in adult and newborn rabbits by inoculation of fibroma virus. Whereas tumors completely regressed in adult rabbits by 3 weeks after virus inoculation, newborn rabbits supported tumor growth for 3 to 4 weeks. In the latter case, some animals died at this time, others survived with a gradual regression of the tumors over an additional period of 5 to 6 weeks. Virus neutralizati...

Immunity in the neonatal animal is primarily maternally derived, either by lymphocytes that pass into the newborn across the placenta or following colostrum ingestion. However, the effect of this passively transferred cellular maternal immunity on the newborn's immune repertoire is not clearly understood. Various studies have shown that colostral lymphocytes are activated and possess functional...

Host defense against infection can broadly be categorized into systemic immunity and cell-autonomous immunity. Systemic immunity is crucial for all multicellular organisms, increasing in importance with increasing cellular complexity of the host. The systemic immune response to Listeria monocytogenes has been studied extensively in murine models; however, the clinical applicability of these fin...
