1. Combined immunodeficiencies
Abstract Objectives: Inborn Errors of Immunity (IEI), also known as primary immunodeficiencies, correspond to a heterogeneous group of congenital diseases that primarily affect immune response components. The main clinical manifestations comprise increased susceptibility to infections, autoimmunity, inflammation, allergies and malignancies. The aim of this

2. Immune system: development and acquisition of immunological competence
Abstract Objectives: To describe the ontogeny of the immune system and the adaptive mechanisms of the immune system in the neonatal period, with an emphasis on transplacental antibody transport and breastfeeding. Source of data: Non-systematic literature review in the PubMed database. Summary of the findings: The last two decades have witnessed a great ad

3. Effect of feeding heat-treated and unheated colostrum on immunoglobulin G absorption, health and performance of neonatal Holstein dairy calves
ABSTRACT. First colostrum is an important source of nutrients and immune factors which are necessary for calves in the first weeks of life. Despite these benefits, colostrum can also represent one of the earliest potential exposures of dairy calves to infectious agents which these patogens can act directly on growth and cause diseases such as scours or septi

4. Serum biochemical profile of neonatal buffalo calves
RESUMO Amostras de sangue de 50 bezerros de búfalo Murrah foram examinados nesse estudo. Os animais foram distribuídos em três grupos de acordo com a paridade de suas genitoras: G1 (n=15) bezerros de búfalas primíparas, G2 (n=19) bezerros de búfalas com 2 a 4 gestações, e G3 (n=16) bezerros de búfalas com cinco ou mais gestações. Amostras de sangu

5. Neonatal immune response of Brazilian beef cattle to vaccination with Clostridium botulinum toxoids types C and D by indirect ELISA
Types C and D strains of Clostridium botulinum are commonly related to avian and mammalian botulism. Although there are numerous vaccine recommendations, little research has been conducted to indicate the real effectiveness of vaccine timing or the ideal immunization protocol for young beef calves. Four commercially available vaccines, two bivalent (Clostrid

6. Caracterização molecular de rotavírus genotipo P[6] de origem humana em um foco de diarreia neonatal suína
Neonatal diarrhea is the major piglet health problem in swine production systems worldwide.In intensive production the porcine serogroup A rotaviruses (PoRV-A) are common cause of diarrhea in suckling and recently weaned piglets. The VP4 and VP7 proteins of the outer layer viral capsid of RV-A are relevant for immunity against rotavirus infection by inducing

7. Apoptose em placenta de mulheres com e sem hipótese de infecção por Streptococcus agalactiae/
Recent advances in Obstetrics and Neonatology improved the attendance to the pregnant and newborn, identifying factors that raise maternal and fetal morbi-mortality. Amongst the main risk factors for neonatal sepsis are the premature parturition and the premature rupture of membranes, which increases the chances of maternal colonization by the Group B Strept

8. Atividade de células entéricas de cordeiros recém-nascidos aleitados com colostro bovino e ovino / Enteric cell activity in newborn lambs fed bovine and ovine colostrum
O objetivo deste estudo foi avaliar o processo de aquisição de anticorpos em cordeiros recém-nascidos aleitados com colostro bovino e ovino, bem como a taxa de proliferação celular no epitélio intestinal. Este estudo contribui com informações sobre a aquisição de imunidade passiva nesta espécie, com o conhecimento do desenvolvimento e maturação

9. Significância clínica da presença de Staphylococcus coagulase-negativo isolados de recém-nascidos de uma unidade de terapia intensiva neonatal em Brasília-DF
Introdução e Objetivos Há longo tempo os S. coagulase-negativo (SCoN) vem sendo reconhecidos como contaminantes em culturas pois fazem parte da flora da pele humana e das membranas mucosas. Nas últimas décadas eles emergiram como agentes etiológicos em infecções e são tanto causas importantes de infecções da corrente sanguínea nosocomiais, princi

10. Estudo da transmissão da imunidade passiva e da mortalidade em cordeiros mestiços de Santa Inês, na região norte de Minas Gerais
The transferring of passive immunity and the causes of mortality lambs breed and crossbreed Santa Inês were studied this work developed in north of Minas Gerais. The transferring of passive immunity was determined by laboratory and field tests. The main causes of neonatal mortality up to 90 days of age were identified by necropsies. Sixty-nine Santa Inês e

11. DNA immunization of neonates induces immunity despite the presence of maternal antibody.
Neonatal animals were not considered as suitable vaccine recipients either because of immune immaturity or because passively delivered antibody interferes with immune induction. In this report, we evaluated the response of neonatal mice to immunization with naked DNA encoding a herpes simplex virus (HSV) protein, and determined if maternally derived HSV anti

12. Intranasal Immunization with Pneumococcal Conjugate Vaccines with LT-K63, a Nontoxic Mutant of Heat-Labile Enterotoxin, as Adjuvant Rapidly Induces Protective Immunity against Lethal Pneumococcal Infections in Neonatal Mice
Immunization with pneumococcal polysaccharides (PPS) conjugated to tetanus toxoid (TT) (Pnc-TT) elicits protective immunity in an adult murine pneumococcal infection model. To assess immunogenicity and protective immunity in early life, neonatal (1 week old) and infant (3 weeks old) mice were immunized intranasally (i.n.) or subcutaneously (s.c.) with Pnc-TT
