1. Effects of Curcuma longa on the intestinal health of chicks infected with Salmonella Typhimurium
ABSTRACT This study was conducted to evaluate the effects of Curcuma longa on the growth performance, intestinal integrity, and antimicrobial activity of chicks colonized by Salmonella Typhimurium. The study included 672 one-day-old male chicks of the CobbTM lineage, which were divided into eight treatment groups with 14 birds per group and six repetitions,

2. Establishment of the bacterial fecal community during the first month of life in Brazilian newborns
OBJECTIVE: The establishment of the intestinal microbiota in newborns is a critical period with possible long-term consequences for human health. In this research, the development of the fecal microbiota of a group of exclusively breastfed neonates living in low socio-economic conditions in the city of São Paulo, Brazil, during the first month of life, was

3. Effects of prebiotics and probiotics on the colonization and immune response of broiler chickens challenged with Salmonella enteritidis
The present study aimed at evaluating the effect of the prebiotic Bio Mos™ (2 kg/ton up to 10 days; 1 kg/ton from 10 to 21 days; and 0.5 kg/ ton from 21 days to slaughter), of the probiotic Lac XCL 5x™ (by spraymixing), of a combination of the two supplements (prebiotic + probiotic), and of one growth promoter antimicrobial agent (Avilamycin at 15 ppm).

5. Intestinal microbiota of patients with bacterial infection of the respiratory tract treated with amoxicillin
The intestinal tract harbors a huge diversity of metabolically-active aerobic and anaerobic bacteria that interact, forming a complex ecosystem. This microbiota has an important role in human metabolism, nutrition, immunity, and protection against colonization by pathogenic microorganisms. Several factors can influence the intestinal microbiota; these includ

6. Use of selective media for detection of cephalothin-resistant bacteria in surgical patients
Bacterial colonization in hospitalized patients is an important step in nosocomial infections. Frequent employment of antimicrobials can modify patients' normal microbiota, favoring colonization and infection by antimicrobial-resistant microorganisms. First-generation cephalosporins are frequently used as prophylactic antibiotics in surgery. Intestinal, orop

7. Colonização e transito intestinal de Salmonella enteritidis e Samonella Typhimurium em frangos de corte no pre abate
The contamination of poultry carcasses by Salmonella is directly related to the contamination levels presented by the chickens when it enters the slaughterhouse. The experiments presented here aimed to the study of the dinamics of Salmonella in the bowells of chickens before slaughtering, including the effect of lactose in the diet (5% in the food) and the d

8. Role of anaerobic flora in the translocation of aerobic and facultatively anaerobic intestinal bacteria.
It is thought that the normal enteric microflora acts not only to prevent intestinal colonization but also to prevent subsequent systemic dissemination of ingested, potentially pathogenic bacteria. To determine the relative roles of specific components of the intestinal bacterial flora in bacterial translocation out of the gut, mice were given various antimi

9. Effects of Intrapartum Penicillin Prophylaxis on Intestinal Bacterial Colonization in Infants
Early-onset group B streptococcal (GBS) infections remain a leading cause of morbidity and mortality in infants. To prevent the vertical transmission of GBS and neonatal GBS infection, guidelines recommend intrapartum penicillin or amoxicillin prophylaxis. This intrapartum antibiotic prophylaxis (IAP) is suspected to favor colonization by antibiotic-resistan

10. Infant mouse model of adherence and colonization of intestinal tissues by enterotoxigenic strains of Escherichia coli isolated from humans.
The ability of enterotoxigenic Escherichia coli H10407, which possesses colonization factor antigen I, to colonize the intestinal mucosa of infant mice was considerably better than that of its colonization factor antigen I-negative derivative H10407-P. The latter strain previously was shown to lack cell adhering ability in vitro and to have a diminished capa

12. Escherichia coli K5 capsule expression enhances colonization of the large intestine in the gnotobiotic rat.
The role of capsule expression in the capacity of Escherichia coli to colonize in the large intestinal environment was studied in a gnotobiotic rat model. The rats were given perorally a mixture of two mutant strains differing in K5 expression. After 2 weeks, the rats were sacrificed, and subsequently intestinal contents, intestinal mucosae, and mesenteric l
