ABSTRACT
SUMMARY

BACKGROUND:

There is evidence of detection of Helicobacter pylori (H. pylori) in the stool of newborns and in the yeast that colonizes the oral cavity of this age group. However, there is a lack of research to confirm it. This study proposes to determine the existence of the bacteria at an early age, specifically in newborns.

OBJECTIVE:

To identify intracellular H. pylori in oral yeasts and to detect antigens of the bacteria in newborn stools.

METHODOLOGY:

Cross-sectional and descriptive study. Samples were obtained from infants (oral swab and meconium). Identification of yeast species was performed using the following techniques CHROMagar Candida, Germinal Tube Test and API Candida Identification System, then the yeasts were observed by light microscopy and fluorescence. Detection of H. pylori antigen in meconium and PCR were performed to amplify specific genes of the bacterium (rRNA16S, cagA, vacA s1a, vacA s1b, vacA s2, vacA m1, vacA m2 and dupA).

RESULTS:

Intracellular H. pylori was detected in yeast of the species Candida glabrata (C. glabrata) isolated from an oral swab of a newborn.

CONCLUSION:

The results of this study evidenced the existence of intracellular H. pylori in newborns.
RESUMO
RESUMO ANTECEDENTES Há evidências de detecçâo de Helicobacter pylori (H. pylori) em fezes de recém-nascidos, como também dentro de leveduras que colonizam a cavidade oral dessa faixa etária. No entanto, faltam investigações que confirmem esses achados.

OBJETIVO:

Identificar H. pylori intracelular em leveduras de origem oral e detectar antígenos dessa bactéria em fezes neonatais.

METODOLOGIA:

Estudo transversal e descritivo. As amostras foram obtidas de bebês (zaragatoa oral e mecônio). As identificações das espécies de leveduras foram realizadas utilizando as seguintes técnicas CHROMagar Candida, teste de tubo germinativo e sistema de identificação API Cândida. As leveduras foram observadas por microscopía óptica e fluorescência. Realizou-se a detecçâo de antígeno de H. pylori em mecônio e PCR para a amplificação de genes específicos desta bactéria (rRNA16S, cagA, vacA s1a, vacA s1b, vacA s2, vacA m1, vacA m2 e dupA).

RESULTADOS:

Foi detectado H. pylori intracelular em leveduras da espécie Candida glabrata (C. glabrata) isoladas a partir de zaragatoas oral de um recém-nascido.

CONCLUSÃO:

Os resultados deste estudo evidenciaram a existência interna de levedura de H. pylori em recém-nascidos.
