Antifungal activity of essential oils against filamentous fungi determined by broth microdilution and vapour contact methods

Aims:  The in vitro activity of some essential oils (EO) (thyme red, fennel, clove, pine, sage, lemon balm and lavender) against clinical and environmental fungal strains was determined.

Bacterial counts of intestinal Lactobacillus species in infants with colic.

Intestinal colonization by lactobacilli is suggested to be a prerequisite to normal mucosal immune functions. An inadequate level of lactobacilli may be involved in appearance of allergic disease of which, infantile colic, is often considered an early clinical manifestation. The aim of the study is to evaluate intestinal lactobacilli in breast‐fed infants with infantile colic and healthy infants. Fifty‐six breast‐fed infants, aged 15–60 days were enrolled in the study and divided into two groups: colicky (30 cases) and healthy (26 cases) according to Wessels criteria. Stool samples were collected, diluted and cultured on selective media. The colonies were counted, reported as colony forming unit (cfu) per gram of faeces and identified by biochemical methods. Different colonization patterns of lactobacilli were found among colicky and healthy infants. Lactobacillus brevis (4.34 × 108 cfu/g) and L. lactis lactis (2.51 × 107 cfu/g) were found only in colicky infants while L. acidophilus (2.41 × 107 cfu/g) was found only in healthy infants. Lactobacillus brevis and L. lactis lactis might be involved in the pathogenesis of infantile colic increasing meteorism and abdominal distension. Further studies are required to understand how the observed differences may be involved in the pathogenesis of this common disorder.
