“…A reduction in the microflora with dietary treatment as observed by Mata et al (1972) may be the result of such a natural clearance of the jejunum on removing the child from his home environment.…”

“…Na década de 70, estudos 12,13 realizados na Guatemala avaliaram a microbiota no tubo digestivo de crianças com desnutrição associada ou não com diarreia. Em um desses artigos 12 , foi avaliada, prospectivamente, a microbiota colônica de quatro crianças com desnutrição energético-proteica grave, antes da terapia nutricional, na fase de estabilização e em dois momentos da fase de recuperação. Constatou-se aumento no número de colônias de anaeróbios colônicos, que incluem os lactobacilos e bifidobactérias, revertendo a inversão da relação anaeróbios/aeróbios observada na desnutrição 12 .…”

“…Em tal contexto não foram encontrados estudos que avaliem a participação dos lactobacilos e bifidobactérias na composição da microbiota intestinal em áreas propícias para o desenvolvimento da enteropatia ambiental. Estudos 12,13 realizados na década de 1970, envolvendo pequeno número de crianças com desnutrição, demonstraram mudanças na microbiota colônica ao longo da terapia nutricional.…”

Lactobacilli and bifidobacteria in the feces of schoolchildren of two different socioeconomic groups: children from a favela and children from a private school

Objective: To determine the number of lactobacillus and bifidobacterium colonies in the feces of schoolchildren from two different socioeconomic levels. Methods:We analyzed fecal samples of children aged 6 to 10 years without gastrointestinal symptoms or recent use of antimicrobials. The first group included 86 children living in a favela in the city of Osasco, state of São Paulo, southeastern Brazil. The second group included 36 children attending a private school in the same city. Body mass index (BMI) was used to assess nutritional status according to the reference values of the National Center for Health Statistics (NCHS). Specific anaerobic culture media were used for isolation of colonies for 48 and 72 hours at 37 °C. The number of colonies was determined using the plate-counting method. Results:The mean lactobacillus (1.125 x 10 9 colony-forming units, CFU/g) and bifidobacterium (1.675 x 10 9 CFU/g) counts in the private school group were higher (p < 0.001) than those in the favela group: 0.250 x 10 9 and 0.350 x 10 9 CFU/g, respectively. In the favela group, children with BMI z score < -1.0 standard deviation (SD) (n = 28) showed lower mean (p < 0.05) lactobacillus (0.100 x 10 9 CFU/g) and bifidobacterium (0.095 x 10 9 CFU/g) counts than the children with BMI ≥ -1.0 SD (n = 57): 0.350 x 10 9 and 0.420 x 10 9 CFU/g, respectively. Conclusion:The microbiota of schoolchildren living in unfavorable environmental conditions shows lower numbers of fecal lactobacillus and bifidobacterium colonies, especially in children with lower BMI values.J Pediatr (Rio J). 2009;85(4):307-314: Lactobacillus, bifidobacterium, socioeconomic factors, nutritional status, environmental exposure, enteropathies. ResumoObjetivo: Determinar o número de colônias de lactobacilos e bifidobactérias nas fezes de crianças escolares, pertencentes a dois estratos socioeconômicos.Métodos: Foram analisadas amostras de fezes de crianças com idade entre 6 e 10 anos sem sintomas gastrointestinais ou uso recente de antimicrobianos. O primeiro grupo foi constituído por 86 crianças, moradoras em uma favela localizada no município de Osasco (SP). O segundo grupo foi constituído por 36 crianças matriculadas em uma escola particular da mesma cidade. O estado nutricional foi avaliado usando o índice de massa corporal (IMC) de acordo com os valores de referência do National Center for Health Statistics (NCHS). O isolamento das colônias foi realizado em meios de cultura específicos em anaerobiose, durante 48 e 72 horas a 37 °C. A determinação do número foi feita pelo método da contagem em placa.Resultados: A mediana de lactobacilos (1,125 x 10 9 unidades formadoras de colônia, UFC/g) e bifidobactérias (1,675 x 10 9 UFC/g) na escola particular foi superior (p < 0,001) ao do grupo da favela: 0,250 x 10 9 e 0,350 x 10 9 UFC/g, respectivamente. No grupo da favela, crianças com escore z de IMC < -1,0 desvio padrão (n = 28) apresentaram menor mediana (p < 0,05) de lactobacilos (0,100 x 10 9 UFC/g) e bifidobactérias (0,095 x 10 9 UFC/g) em relação às cria...

“…Little information is available about well children in developed countries but Challacombe, Richardson & Anderson (1974) demonstrated low counts of less than 100 bacteria per ml in the small bowel in nearly half the children they studied in Britain. In contrast, the jejunal flora of apparently normal Guatemalan children is more profuse and varied (Mata et al 1972a). Our findings show no major differences between the London and the Jamaican children but we isolated bacteroides on four occasions and bifidobacteria on one occasion from the small bowel of Jamaican children.…”

STJMMARYThe flora of both faeces and small bowel lumen was studied in children with gastroenteritis from London, England, and Kingston, Jamaica.Clinical and laboratory differences between these two groups are described. All bacterial groups in the faeces were greatly altered during gastroenteritis and this particularly affected anaerobic organisms. These changes generally reverted rapidly to normal after the illness.The small bowel flora was also altered during gastroenteritis; there was a tendency for a wider range of organisms including anaerobes to be isolated from the children in Jamacia than from those in England.
