1. Evaluation of the protective capacity of new mild Citrus tristeza virus (CTV) isolates selected for a preimmunization program
The use of tolerant rootstocks and preimmunization has satisfactorily controlled losses associated with the Citrus tristeza virus (CTV). Several researchers have shown that CTV mild isolates that are selected in the same region where they are used are superior to isolates obtained from other areas. Thus, budwoods of 20 outstanding citrus trees were collected

2. Avaliação da resposta humoral à vacina pneumocócica conjugada 7-valente em crianças com asma moderada em uso de corticóide inalatório e em crianças com fibrose cística / Humoral immune response to 7-valent conjugated pneumococcal vaccine among children with moderate asthma in use of inhaled glucocorticosteroids and cystic fibrosis children
Pneumococcal infections are an important morbi-mortality cause among children. Until 2000, it was only available the 23-valent polysaccharide pneumococcal vaccine for children over two years old. This vaccine was recommended for cystic fibrosis (CF) children and to asthmatics children in use of oral corticosteroids, among other recommendations. From 2000, it

3. Placental transfer of Haemophilus influenzae type b antibodies in malnourished pregnant women
This study evaluated the vaccination response to Haemophilus influenzae type b (Hib) in malnourished pregnant women (MN), cord blood (CB) and in infants at two and six months of age for comparison with a control group (C). Twenty-eight malnourished pregnant women and 29 pregnant controls were immunized with conjugated Act-HIB® in the third trimester of preg

4. Efeito de estirpes fracas do PRSV-W e do ZYMV sobre a produção de quatro variedades de Cucurbita pepo / Effect of protective mild strains of PRSV-W and ZYMV on the yield of four varieties of Cucurbita pepo
Zucchini squash (Cucurbita pepo L.) is widely cultivated in Brazil, especially in the State of São Paulo, which is the major producer. Nine viruses capable to infect this species have already been described in Brazil. The most frequent and responsible for significant yield losses are the potyviruses Papaya ringspot virus - type W (PRSV-W) and Zucchini yello

5. Search for mild strains of Passion Fruit Woodiness Virus (PWV) and attempt to control the passion fruit woodiness by preimmunization. / Seleção de estirpes fracas do Passion Fruit Woodiness Virus e tentativas de premunização para o controle do endurecimento dos frutos do maracujazeiro.
Este trabalho teve por objetivo selecionar estirpes fracas do Passion fruit woodiness virus (PWV) e avaliar o seu efeito protetor para o controle do endurecimento dos frutos do maracujazeiro. Foram selecionadas seis estirpes fracas do PWV. Três a partir de plantas de elite, encontradas em pomares severamente afetados pelo vírus (F-101, F-102 e F-103) e tr�

6. Development of an enzyme-linked immunosorbent assay for detection of IgM antibodies to Babesia bigemina in cattle
A crude antigenic preparation of Babesia bigemina was used to develop an ELISA for the detection of IgM antibodies. Optimal dilutions of the antigen, using positive and negative reference sera, were determined by checkerboard titrations. Negative sera from cattle imported from tick-free areas, serum samples collected from infected B. bigemina cattle were use

7. Influence of preimmunization with tetanus toxoid on immune responses to tetanus toxin fragment C-guest antigen fusions in a Salmonella vaccine carrier.
We have previously described a new system for the delivery of recombinant antigens in live Salmonella vaccines as genetic fusions to the C terminus of fragment C of tetanus toxin (TetC) driven by the anaerobically inducible nirB promoter. It has been reported that preimmunization with tetanus toxoid (TT) can suppress the antibody response to peptides chemica

8. Characterization of Bactericidal Immune Responses following Vaccination with Acellular Pertussis Vaccines in Adults
Sera from six adults, collected before and after acellular pertussis vaccination, and from a placebo control were examined for the ability to elicit two bactericidal immune defenses, (i) antibody-dependent complement-mediated bacterial lysis and (ii) opsonization and phagocytosis by human neutrophils. The samples were chosen based on low preimmunization tite

9. The prevalence and direct costs of pre-immunization testing for hepatitis A in general practice.
Two hundred and twenty patients in one general practice travelling to destinations where immunization against hepatitis A virus (HAV) is recommended were tested for their HAV immune status before immunization. Age-specific prevalence of prior immunity to HAV was estimated. The relative costs of pre-immunization testing and immediate immunization were compare

11. Coreactivity of Legionella pneumophila immune sera in the Mycoplasma pneumoniae complement fixation test.
Sheep and guinea pigs were immunized with cellular and extracellular antigen from Legionella pneumophila bacteria. After immunization, the animals developed immunoglobulin G titers against the immunizing agent. The same sera were also tested in a Mycoplasma pneumoniae complement fixation test. All the preimmunization sera from sheep showed positive M. pneumo

12. Induction of immune unresponsiveness to concordant islet xenografts by intrahepatic preimmunization and transient immunosuppression.
Streptozotocin-induced, diabetic mice (C57BL/6) were preimmunized by injecting 25 low temperature, cultured Wistar-Furth (WF) rat islets into the portal vein, and the recipients received one injection of mouse and rat antilymphocyte sera. 3 wk later, fresh WF islets were transplanted under the kidney capsule of the preimmunized recipients, and normoglycemia
