1. Programa de Imunização Infantil em Umuarama-PR: um estudo dos fatores associados a atrasos de vacinação / Program of infantile immunization in Umuarama-PR: a study of the factors associates the vaccination delays
O atraso vacinal configura-se quando uma criança não recebe algumas das vacinas que estavam indicadas e programadas para ela, conforme preconizado pelo calendário vacinal vigente. A criança com atraso vacinal possui risco aumentado para contrair doenças imunopreveníveis, como também diminui a resistência na rede de imunidade comunitária. Elementos c

2. An unlikely partnership: parasites, concomitant immunity and host defence.
Concomitant immunity (CI) against macroparasites describes a state of effective anti-larval immunity coupled with persistent adult infection. Experimental studies indicate that immunologically concealed adult worms might promote anti-larval immunity via the release of cross-reactive antigens, thus creating a barrier against continual infection and restrictin

3. Cross-protection against lymphocytic choriomeningitis virus mediated by a CD4+ T-cell clone specific for an envelope glycoprotein epitope of Lassa virus.
Recombinant vaccinia virus expressing the Lassa virus (LV) envelope glycoprotein precursor, V-LSGPC, was used to study the basis of LV-induced cross-protective immunity against the closely related arenavirus lymphocytic choriomeningitis virus (LCMV). C3H/HeJ mice primed with V-LSGPC developed neither circulating antibodies nor CD8+ cytotoxic T cells specific

4. Plasmid-containing strains of Streptococcus mutans cluster within family and racial cohorts: implications for natural transmission.
The transmission of mutans streptococci is thought to occur along familial lines based on investigations which have shown common strains within family units by using phenotypic typing methods, such as bacteriocin production and immunity profiles and serotyping. Difficulties in implementing these typing methods, coupled with conflicting interpretations of res
