1. Growth performance and intestinal health of broilers fed a standard or low-protein diet with the addition of a protease
ABSTRACT We evaluated the effects of a protease supplementation on the growth performance and intestinal health of broilers. Cobb chicks (392; 1-42 d) were divided into four treatments (seven replicates of 14 birds each). There were two feed formulations: a standard diet (SD) and a low crude protein and digestible amino acids diet (Low CP&AA). The two diets

2. Effect of Broiler Breeder Age on the Intestinal Mucosa Development of the Embryos at 20 Days of Incubation
ABSTRACT This study investigated the effect of broiler breeder age on the morphological development of the small intestine broiler embryos (villus height, crypt depth, microvillus height, and villus density) at 20 day of incubation. Eggs obtained from 30- and 60-wk-old broiler breeders were used. The results showed that embryos from older broiler breeders pr

3. Campylobacter Jejuni Increases Transcribed Il-1 B and Causes Morphometric Changes in the Ileal Enterocytes of Chickens
Abstract Campylobacteriosis is a worldwide foodborne zoonosis disease caused by Campylobacter jejuni. This microorganism is considered a commensal bacterium in chicken hosts. C. jejuni produces epithelial cell modifications and induces a cytokine gene transcription innate immunity repertoire. In the present study, we describe the invasiveness, morphological

4. Resposta celular à infecção por Campylobacter. jejuni em embriões e explants de íleo de aves e participação do citoesqueleto e lisossomos no processo de invasão em células CACO-2
The host-pathogen interactions of C. jejuni is a little explored subject in birds and humans. Thus, this study aimed to evaluate the passage and the effects of virulent strain of C. jejuni IAL 2383 in SPF embryos of birds, the expression of cytokines and morphological changes in SPF birds explants ileum infected with C. jejuni and verify the cytoskeleton and

6. Caracterização do mecanismo de controle do pH no tubo digestivo de Lutzomyia longipalpis (Lutz e Neiva, 1912) (Diptera: Psychodidae) e sua importância no desenvolvimento de Leishmania Ross, 1903
The midgut pH control is a key step during Lutzomyia longipalpis digestion process. Phlebotomines have to change from a favorable carbohydrate digestion (luminal pH = 6) to blood digestion (luminal pH~8). Until blood ingestion, the acidic pH in the midgut is rigorously maintained closely to pH 6 by an efficient mechanism. Apparently, alkalization in the abdo

7. Brazilian contribution for a better knowledge on the biology of Toxoplasma gondii
Historically, scientists in Brazil has significantly contributed to the biology, cultivation and structural organization of the pathogenic protozoan Toxoplasma gondiiand its interaction with host cells, starting with the description of the protozoan by Splendore in 1908. The intracellular and extracellular corpuscoli observed in rabbits, corresponded to what

8. Structural and functional analysis of VT1 and YP170B vitellins from the Rhabditid nematodes Oscheius tipulae and Caenorhabditis elegans. / Estudo das vitelinas VT1 e YP170B dos nematoides rabditídeos Oscheius tipulae e Caenorhabditis elegans: aspectos estruturais e funcionais.
The N-terminal region of OTI-VIT-1 was expressed and the recombinant polypeptides were purified. OTI-VIT-1 may be homologous to the vitellin YP170B from C. elegans. We identified an intron in the 5 region and two in 3region from Oti-vit-1. Monospecific antisera to PVIT1HisC confirmed that the gene Oti-vit-1 encodes VT1. The recombinant polypeptide P40-H, cor

9. Detecção de Lawsonia intracellularis em aves comerciais através da reação em cadeia pela polimerase (PCR) / Detection of Lawsonia intracellularis in chicken by polymerase chain reaction (PCR)
Lawsonia intracellularis is an obligate intracellular bacterium responsible for proliferative enteritis in many animals, such as swine, deers, rats, hamsters, guinea pigs, rabbits, ovine, horses, foxes, dogs, ferrets, no human primats, emus and ostrichs. Currently there is no reports about the occurrence of this agent or clinical signs of its infection in ch

10. Effects of IgG and IGF-I of the first milky meals on the serum fluctuation and characteristics of the intestinal epithelium in the newborn calves / Efeito de IgG e IGF-I das primeiras refeições lácteas sobre a flutuação sérica e características do epitélio intestinal em bezerros recém-nascidos
O objetivo deste trabalho foi estudar os efeitos de diferentes manejos de fornecimento de colostro sobre a aquisição sérica de imunoglobulina G (IgG) e do fator de crescimento semelhante à insulina-I (IGF-I), bem como as modificações morfológicas e morfométricas do epitélio intestinal em bezerros recém-nascidos. Foi utilizado o fornecimento prolong

11. Seric antibodies anti-hemorrhagic Escherichia coli (EHEC) in healthy Brazilian adults / Anticorpos séricos anti Escherichia coli enterohemorrágica (EHEC) em adultos saudáveis da Grande São Paulo
Gastroenteritis is still an important public health problem in developing countries and Escherichia coli are frequent agents of diarrhea. Brazilian adults present antibodies reactive with the principal virulence factors of enteropathogenic E. coli (EPEC), which have many genetic and antigenic similarities with enterohemorrhagic E. coli (EHEC), that may be re

12. Cholesterol induces fetal rat enterocyte death in culture
The effect of cholesterol on fetal rat enterocytes and IEC-6 cells (line originated from normal rat small intestine) was examined. Both cells were cultured in the presence of 20 to 80 µM cholesterol for up to 72 h. Apoptosis was determined by flow cytometric analysis and fluorescence microscopy. The expression of HMG-CoA reductase and peroxisome proliferato
