1. Feeding heat killed pneumococci grown in milk produces a fair degree of immunity. 2. Feeding acid killed degraded aruvilent organisms produces little protection. 3. Feeding the desiccated, mechanically disrupted organisms creates a high degree of protection. 4. Feeding the Berkefeld filtrate of sodium glycocholate dissolved cells produce a high degree of immunity. 5. A single ingestion of th...

Heat shock proteins (Hsps) are highly conserved biomolecules that are constitutively expressed and generally upregulated in response to various stress conditions (biotic and abiotic). Hsps have diverse functions, categorizations, and classifications. Their adaptive expression in fungi indicates their significance in these diverse species, particularly in dimorphic pathogens. Histoplasma capsula...

This investigation determined the serum agglutination activity and serum bactericidal response after rabbit immunization with Pseudomonas paucimobilis. Agglutination activity of antisera showed a twofold increase in titer from before immunization to 4 weeks post-immunization and peaked at 8 weeks post-immunization with a titer of 1:512. 2-Mercaptoethanol reduction of immunoglobulin M decreased ...

To study the role of subdominant epitopes in tumor rejection we have used EL4 tumor cells and their ovalbumin (OVA)-transfected counterpart E.G7. Immunization of mice with irradiated EL4 cells conferred protection against challenge with EL4 and E.G7. Surprisingly, immunization with irradiated E.G7 cells did not protect against a subsequent challenge with EL4 or E.G7. Growth of E.G7 tumors in E....

Multisystemic disease caused by Small Ruminant Lentiviruses (SRLV) in sheep and goats leads to production losses, to the detriment of animal health and welfare. This, together with the lack of treatments, has triggered interest in exploring different strategies of immunization to control the widely spread SRLV infection and, also, to provide a useful model for HIV vaccines. These strategies inv...

background: rhipicephalus ( boophilus ) annulatus tick is one of the most important ectoparasite of cattle. re­cently, several laboratories in the world have been concentrated on immunizing cattle against tick using various types of tissue extracts of ticks. the aim of this study was to evaluate the effect of immunization of cattle with tick salivary gland extract on biological parameters of ti...

Herpes simplex virus (HSV) most frequently initiates infection at a mucosal surface; thus mucosal immune responses are likely to be important in defense against HSV infection. We have examined the effects of eliciting mucosal as well as systemic immune responses on protection against genital challenge infection with virulent HSV-2 in mice immunized with a replication-defective mutant of HSV-2. ...

background: the increasing incidence of pertussis among adolescents and adults in recent years is an alarming factor in transmission of the infection to non-immune infants and children. vaccination of pregnant women, immediately after delivery and before being discharged from the hospital may help to protect mothers and their newborns against the disease. decision making process, regarding mate...
