INTRODUCTION: Laboratory-based surveillance is an important component in the control of vancomycin resistant enterococci (VRE). METHODS: The study aimed to evaluate real-time polymerase chain reaction (RT-PCR) (genes vanA-vanB) for VRE detection on 115 swabs from patients included in a surveillance program. RESULTS: Sensitivity of RT-PCR was similar to primary culture (75% and 79.5%, respectively) when compared to broth enriched culture, whereas specificity was 83.1%. CONCLUSIONS: RT-PCR provides same day results, however it showed low sensitivity for VRE detection.

The essential oils of the leaves and branches of Sextonia rubra were obtained by hydrodistillation and analyzed by GC-FID and GC-MS. In the leaves were identified as the major constituents α-pinene (21.7%), β-pinene (15.4%), α-copaene (12.5%) and germacrene D (12.1%). In the branches essential oil, α-copaene (22.9%), β-selinene (7.9%) and β-elemene (7.2%) were identified as the most abundant constituents. This paper describes for the first time the composition of these essential oils.

1. Pesquisamos a atividade antibacteriana em 14 amostras de Aspergillus niger da National Collection of Type Cultures. 2. Em meio de Raulin e Mosseray, sete amostras apresentaram atividade total, nunca superior a 1:10, contra Staphylococcus aureus nº 553, sendo que as amostras 1.161 e 2.390 permaneceram ativas por mais de 40 dias. 3. A utilização do meio de Czapek-Dox com 5% de "corn-steep" não melhorou os resultados obtidos com o meio de Raulin e Mosseray. 4. No meio de levedo peptonado, todas as amostras apresentaram-se inativas.

Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and A. girellae (Yamaguti, 1935) Campana-rouget, 1955. The validity of the proposed species is discussed.

Otodistomum cestoides (van Beneden, 1871) (Azygiidae: Digenea) is reported for the first time from Psammobatis scobina and Raja flavirostris. The skates were caught off the coast of San Antonio, Chile.

Observations were carried out on the reproductive behavior of Synthesiomyia nudiseta females. The results of the biological parameters were: pre-oviposition period (15.5 ± 4.7 days), oviposition period (25.4 ± 14.7 days), number of eggs per oviposition (95.9 ± 18.4) rate of ovipositant females (97.5%), number of ovipositions (5.31 ± 3.2), number of eggs per females (509.7 ± 324.9), rate of hatching (68.0 ± 19.0), female longevity (53.2 ± 14.7 days), reproductive potential (67.4%) and reproductive investiment (4.1).

The isolation of vancomycin resistant enterococci (VRE) in Brazil has rapidly increased, following the world wide tendency. We report in the present study the first isolation of vancomycin resistant Enterococcus faecalis (VRE) in the Northeast of Brazil. The four VRE isolates were characterized for antimicrobial susceptibility, genotypic typing by macro restriction of chromosomal DNA followed by pulsed-field gel electrophoresis and for characterization of the Tn1546-like element and plasmid contents. The isolates showed resistance to multiple antibiotics and a single genotype profile, suggesting the dissemination of a single clone among the patients. Tn1546 associated to genetic elements as plasmids shows the importance of infection control measures to avoid the spreading of glycopetide resistance by conjugative transfer of VanA elements.
