Knowledge of the geographic distribution of plants is essential to underpin the understanding of global biodiversity patterns. Vascular epiphytes are important components of diversity and functionality of Neotropical forests but, unlike their terrestrial counterparts, they are under-represented in large-scale diversity and biogeographic analyses. This is the case for the Atlantic Forest - one o...

Total, fluorescent, and pectolytic epiphytic bacterial population sizes were quantified on leaves of different age groups of broad-leaved endive during field cultivation from leaf emergence until harvest. Greater bacterial population densities (log(inf10) CFU per square centimeter) were observed on outer leaves than on inner leaves of the plants throughout the growing season. These differences ...

Arbuscular mycorrhizal fungi (AMF) and dark septate (DSF) are symbionts that associated with the roots of plants, including epiphytic lycophytes ferns. Paris-type mycorrhiza glomoid structures most common forms colonization in these plants. This work aimed to evaluate occurrence ferns as well diversity AMF spores recovered from substrate eleven species. Roots Asplenium gastonis, Campyloneurum a...

Microbiota of beehive products are very little known. We report here for the first time six metagenomes of royal jelly, pollen, and different types of honey from wild and cultivated lavender, chestnut, and fir honeydew. Four metagenomes of epiphytic and endophytic microbiota of lavender and rose flowers are also reported.

Cellulitis and erysipelas are common skin infections usually caused by Staphylococcus aureus and streptococci. Gram-negative rods are rarely implicated. We report here a case of dermohypodermitis and bactaeremia caused by Erwinia billingiae, a Gram-negative bacteria usually pathogenic and epiphytic to pome fruit tree.

Bacterial brown spot (caused by Pseudomonas syringae pv. syringae van Hall) and halo blight (caused by P. syringae pv. phaseolicola (Burk.) Young, Dye, and Wilkie) are two important diseases of dry beans (Phaseolus vulgaris L.) in Colorado and other parts of the world (14). These bacterial pathogens are of particular interest for the following reasons. Though there is potential for using epiphy...

The relationship between nutrients leached onto the leaf surface and the colonization of plants by bacteria was studied by measuring both the abundance of simple sugars and the growth of Pseudomonas fluorescens on individual bean leaves. Data obtained in this study indicate that the population size of epiphytic bacteria on plants under environmentally favorable conditions is limited by the abun...

Although Salmonella enterica apparently has comparatively low epiphytic fitness on plants, external factors that would influence its ability to survive on plants after contamination would be of significance in the epidemiology of human diseases caused by this human pathogen. Viable population sizes of S. enterica applied to plants preinoculated with Pseudomonas syringae or either of two Erwinia...

Dry remains of the herbal species plantain ( Plantago major ), wormwood Artemisia vulgaris ) and reed grass Calamagrostis acutiflora were used as a natural source for isolation β- mannanase producing strains. They isolated by using carob gum single carbon energy. Each chosen plant was found to be colonized with dominant epiphytic group microorganism, although plants had been collected in same l...
