Dos nuevas especies de <Emphasis Type=Italic>Staelia</Emphasis> (Rubiaceae) con hojas ternadas del nordeste de Brasil

Two new Brazilian species of Staelia with ternate leaves are described and illustrated. The first, Staelia paganuccii, was collected in the cerrado biome, whereas the second, S. domingosii belongs to the Caatingas domain of the Chapada Diamantina complex. The affinities of the two species within the genus are discussed. Photographs of the plants in their natural environments are provided. A brief commentary on the inflorescence structure of Staelia is presented and its importance is discussed.     

Cuatro especies nuevas de <Emphasis Type="Italic">Telipogon</Emphasis> (Orchidaceae) de los bosques montanos de Bolivia

Four new species of Telipogon are described and illustrated: T. cotapatensis, T. juan-torrezii, T. oliganthus and T. pubescens. All were collected from the montane forest of Cotapata National Park, Nor Yungas Province, Department of La Paz, Bolivia.     

Fenologia y seleccion de habitat de las especies de sirfidos afidofagos (Dipt.: Syrphidae) mas frecuentes en cultivos cerealeros y forrajeros en la provincia de buenos aires,argentina

Phenology and habitat selection of the aphidophagous syrphid species most frequently found in crops and pastures in the Province of Buenos Aires, Argentina. The paucity in ecological studies on aphidophagous syrphid flies (Diptera, Syrphidae) of the neotropical region is particularly pronounced in Argentina. In order to increase the database on these natural enemies, the phenology and habitat selection of six syrphid flies (Dipt., Syrphidae):Syrphus phaeostigma (L.);Allograpta obliqua (Wied.);Allograpta exotica (Wied.);Pseudodorus clavatus (L.);Platycheirus carposcalis (L.) andOcyptamus argentinensis (Thorn.) were studied in the Province of Buenos Aires (Argentina). The moment of the year in which adults, eggs, larvae and pupae of these species are found was recorded. The phenologies found for the species in our area are similar to those found for other species of the same genera in other parts of the world. These aphidophagous syrphids are not evenly distributed in all the systems sampled, evidencing a preference for either one of the following types of habitat: cereal crop, lucerne, soya, bushes or prairies. These results are potentially useful in terms of crop and pest management practices.

     

A new combination in Spermacoce (Rubiaceae) and lectotypification of Borreria terminalis

Borreria terminalis Small is recognized as a species distinct fromS. verticillata L. and as an endemic to southern Florida and is transferred to the genusSpermacoce L. A new combination,S. terminalis (Small) Kartesz & Gandhi, is proposed, and a lectotype is designated.     

Cinco especies nuevas de <Emphasis Type=Italic>Aechmea</Emphasis> (Bromeliaceae: Bromelioideae) para Colombia

Se describen e ilustran cinco especies nuevas de Aechmea (Bromeliaceae: Bromelioideae) para Colombia: A. confertiflora y A. viridispica del norte de los Andes, A. longipedunculata y A. longiramosa de la planicie amazónica y A. baudoensis de la región biogeográfica del Chocó. Además, para cada especie se presentan notas sobre sus relaciones taxonómicas, estado de conservación, hábitat y distribución.     

Novelties in spermacoceae (Rubiaceae) from Bolivia and Paraguay

One new Bolivian species (Borreria pazensis) and three new varieties (Borreria densiflora var.minima, Richardia, scabra var.chacoensis andStaelia virgata var.killeenii) are described and illustrated. The genusDiodella, with three species (D. apiculata comb. nov., D. radula comb. nov., andD. teres), is reported for the first time.Borreria limae, B. wunschmannii, B. scabiosoides var.scabiosoides, andB. scabiosoides var.anderssonii are also reported as new to Bolivia.     

Antibacterial effect of borreverine, an alkaloid isolated from Borreria verticillata (Rubiaceae)

Borreria verticillata, a very common tropical plant, is used in traditional pharmacopeia to recover cutaneous infections. The Borreverine alkaloid extracted from this plant had an antimicrobial action in vitro. The minimal inhibitory concentration is lower than 50 micrograms/ml for Gram positive cocci, (specially Staphylococcus aureus) and than 6 micrograms/ml for Vibrio cholerae and upper than 200 micrograms/ml for several Gram negative rod-bacteria (Enterobacteria and Pseudomonas). These preliminary results underline the interest in the research about the antimicrobial agents from plant origin, in particular concerning naturally or chemically modified alkaloids.

Existencia de un foco endemico de rinosporidiosis en la provincia Del Chaco. V. Estudio de nuevas observaciones y consideraciones finales

Summary In the East Center area of the Chaco province (Argentina) 41 cases of rhinosporidiosis have been studied: 6 cases in humans, 33 cases in horses, 1 case in dog and also 1 in cow.The authors assume that there is an endemic focus of rhinosporidiosis in this country whose center may be situated in the Villa Angela region.30 cases of rhinosporidiosis in horses and 1 in humans is the authors' contribution to the study of this disease in the province of Chaco (Argentina).     

Dos formas clinicas muy raras en nuestros climas: Actinomicosis y Blastomicosis cutaneas de tipo vegetante

Summary This study reports a case of a male patient, the first in Spain, afflicted with tuberous and vegetating lesion of the skin: actinomycosis vegetans. The culture for the causative organism remained negative. The histologic sections, however, showed typical, polynuclear-lymphocytic, dermal infiltration with micro-abscesses with the typical actinomycotic granules. Also the first case of Blastomycosis of the skin is presented. There were many round, double contoured bodies in the center of the abscesses. The culture was positive for micrococcus or torula.

Recomendaciones GEMICOMED/GEIRAS-SEIMC para el manejo de las infecciones y colonizaciones por Candida auris

Candida auris is a new species of Candida that causes nosocomial outbreaks in several countries around the world, including Spain. C. auris is resistant to fluconazole and multi- and pan-resistant strains have been described. It is highly transmissible and can survive long term in the hospital environment, causing long-lasting outbreaks that are difficult to detect in early stages, and making it difficult to control and eradicate. It is currently an emerging threat to global health.This document provides a set of guidelines, developed by a multidisciplinary team, to limit the impact and facilitate the control of C. auris infection based on the experiences gathered in the Spanish and English outbreaks. The implementation of early and strict surveillance and control measures is essential to prevent the spread of the outbreak, which can spread over time, posing a significant risk to complex, critical and immunocompromised surgical patients. Immediate notification of C. auris isolation to clinical and infection control teams, as well as to health authorities and institutions, is essential to implement infection control measures at all levels in a timely manner, to prevent internal and inter-centre transmission, and to ensure a proper surveillance and prevention to patients who are already colonized and can develop an infection.
