16s-23S rDNA: polymorphisms and their use for detection and identification of Xylella fastidiosa strains BJM
Martinati,Juliana Camargo; Pacheco,Flávia Tereza Hansen; Miranda,Vitor Fernandes Oliveira de; Tsai,Siu Mui.
Strains of Xylella fastidiosa from several hosts (coffee, citrus, grape, almond, oleander, peach, plum, etc.) were characterized by analyzing the content of the nucleotide sequences of 16S-23S rDNA (coding for a small subunit ribosomal RNA) spacer region (ITS). Current methods for sequencing the ITS region yields partial sequences that do not contribute with significant information. According to this fact, new primers have been designed in order to obtain a complete sequence and facilitate the sequencing. The complete 16S-23S sequences from 08 strains were amplified through PCR using the primers designed in our lab. The 16S-23S sequences obtained were compared with 52 others sequences entries in GenBank database. The results revealed a higher level of...

A key to the Afrotropical genera of Muscidae (Diptera) Zoologia
Couri,Márcia S..
A key to 57 of the 58 Afrotropical Muscidae (Diptera) genera is given. The previous Catalogue of Afrotropical Diptera published about 25 years ago by Adrian C. Pont was used as a taxonomic guide, to which the more recently synonyms and taxonomic changes were updated. For each genus, geographical distribution and number of valid species in this region are also included. Some morphological diagnostic characters are illustrated in order to help the use of the key.

A Linnaeus NGTM interactive key to the Lithocolletinae of North-West Europe aimed at accelerating the accumulation of reliable biodiversity data (Lepidoptera, Gracillariidae) Naturalis
Doorenweerd, C.; Haren, M.M. van; Schermer, M.; Pieterse, S.; Nieukerken, E.J. van.
We present an interactive key that is available online through any web browser without the need to install any additional software, making it an easily accessible tool for the larger public. The key can be found at http://identify.naturalis.nl/lithocolletinae. The key includes all 86 North-West European Lithocolletinae, a subfamily of smaller moths (“micro-moths”) that is commonly not treated in field guides. The user can input data on several external morphological character systems in addition to distribution, host plant and even characteristics of the larval feeding traces to reach an identification. We expect that this will enable more people to contribute with reliable observation data on this group of moths and alleviate the work-load of taxonomic...

A novel acidophilic, thermophilic iron and sulfur-oxidizing archaeon isolated from a hot spring of tengchong, yunnan, China BJM
Ding,Jiannan; Zhang,Ruiyong; Yu,Yizun; Jin,Decai; Liang,Changli; Yi,Yang; Zhu,Wei; Xia,Jinlan.
A novel thermoacidophilic iron and sulfur-oxidizing archaeon, strain YN25, was isolated from an in situ enriched acid hot spring sample collected in Yunnan, China. Cells were irregular cocci, about 0.9-1.02 µm×1.0-1.31 µm in the medium containing elemental sulfur and 1.5-2.22 µm×1.8-2.54 µm in ferrous sulfate medium. The ranges of growth and pH were 50-85 (optimum 65) and pH 1.0-6.0 (optimum 1.5-2.5). The acidophile was able to grow heterotrophically on several organic substrates, including various monosaccharides, alcohols and amino acids, though the growth on single substrate required yeast extract as growth factor. Growth occurred under aerobic conditions or via anaerobic respiration using elemental sulfur as terminal electron acceptor. Results of...

A simple and reliable PCR-restriction fragment length polymorphism assay to identify Candida albicans and its closely related Candida dubliniensis BJM
Ge,Yi Ping; Wang,Le; Lu,Gui Xia; Shen,Yong Nian; Liu,Wei Da.
Candida dubliniensis is an emerging pathogen capable of causing superficial as well as systemic infections. Due to its close similarity to C. albcians, conventional methods based on phenotypic traits are not always reliable in identification of C. dubliniensis. In this study, we developed a PCR-restriction fragment length polymorphism (RFLP) assay to identify and discriminate between the two closely related species. The D1/D2 region of 28S rDNA was amplified by PCR and enzymatically digested by ApaI and BsiEI respectively. PCR products of both species were digested into two fragments by ApaI, but those of other yeast species were undigested. BsiEI cut the PCR products of C. albicans into two fragments but not those of C. dubliniensis. Thus two species were...

Age Estimation from Ossification of the Medial Clavicular Epiphysis by Computed Tomography International Journal of Morphology
El Morsi,Doaa A.; Abo El-Atta,Hend M; ElMaadawy,Merit; Tawfik,Ahmed M; Batouty,Nihal M.
The current study intended to evaluate the accuracy of age estimation from the development of the medial clavicular epiphysis (sternal end of the clavicle) in Egyptian population using computed tomography (CT) and to develop a discriminant formula that can be used in Egyptians. The study was conducted on 142 subjects (84 males and 58 females) after taken informed consent. They were subjected to multi-slice CT on the medial end of clavicles of both sides. The results revealed that the age of non - union was seen at 8­17 years; incomplete union at 15­20 years and complete union was seen at 20 years. It is concluded that the ossification of medial clavicular end could be used for age estimation. Also CT is a good visualization tool to be used. Regression...

Alternative techniques to study characters of the genitalia in Lepidoptera Neotropical Entomology
Dias,Fernando M S; Casagrande,Mirna M; Mielke,Olaf H H.
The present note aims to describe two alternative methods for observing genitalia in Lepidoptera. The first one provides means to examine both male and female genitalia without spoiling the scales of the abdomen, preserving it attached to the thorax and aesthetically similar to an unexamined specimen. The second one provides ways of observing certain characters on the male genitalia in a non-destructive way, and does not depend on time-consuming removing and dissection of the abdomen. It is expected that the presented techniques will help on morphological studies and on identifying similar species which consistently differ in genitalic armatures.

An external tag for fish: tagging effects in different fish size classes and its influence on growth performance and hematology of Lophiosilurus alexandri (Siluriformes: Pseudopimelodidae) Neotropical Ichthyology
Boaventura,Túlio P.; Gil,Viviane S. B.; Gil,Camila S. B.; Peres,Anderson M.; Luz,Ronald K..
ABSTRACT This study tested an external tag for juveniles of Lophiosilurus alexandri and measured the effects of tagging in different size classes of fishes. Experiment 1 evaluated the retention rate and influence of the tag on survival and growth of three hundred fishes divided Small, Medium and Large size classes. After 90 days of experiment the fishes had 100% survival and the tag had a higher retention rate for animals of the Large size class. Experiment 2 evaluated the tag’s influence on hematology parameters of forty-two fishes at 5, 10 and 30 days post-tagging. In this experiment both tagged and untagged animals experienced 9.4% mortality. The hematocrit was higher on the 30th day for tagged animals than for untagged animals. No difference was...

An illustrated key to male Actinote from Southeastern Brazil (Lepidoptera, Nymphalidae) Biota Neotropica
Francini,Ronaldo Bastos; Penz,Carla M..
In certain times of the year, Actinote butterflies can be vastly abundant in Southeastern Brazil, thus representing conspicuous denizens of our fauna. Their wing coloration allows for the recognition of five major patterns, which probably resulted from mimicry. Furthermore, examination of series of field-collected and reared specimens clearly demonstrates a high intra-specific variation in wing color pattern. In concert, inter-specific resemblance (mimicry) and intra-specific variation make it difficult to discriminate Actinote species from each other. This key aims at providing a tool for identification of male Actinote. To that effect, we provide diagnostic characters and illustrations of wings and male genitalia for 22 species. We hope that the clear...

Antibiotic susceptibility profile of bacilli isolated from the skin of healthy humans BJM
Tarale,Prashant; Gawande,Sonali; Jambhulkar,Vinay.
Abstract In the present work, twelve bacilli were isolated from four different regions of human skin from Bela population of Nagpur district, India. The isolated bacilli were identified by their morphological, cultural and biochemical characteristics. Seven isolates were Gram negative rods, out of which five were belong to genus Pseudomonas. Three among the five Gram positive isolates were identified as Dermabactor and the remaining two Bacillus. Their antimicrobial susceptibility profile was determined by Kirby-Bauer disc diffusion method. The isolates showed resistance to several currently used broad-spectrum antibiotics. The Dermabactor genus was resistant to vancomycin, although it was earlier reported to be susceptible. Imipenem was found to be the...

Yeasts are becoming a common cause of nosocomial fungal infections that affect immunocompromised patients. Such infections can evolve into sepsis, whose mortality rate is high. This study aimed to evaluate the viability of Candida species identification by the automated system Vitek-Biomerieux (Durham, USA). Ninety-eight medical charts referencing the Candida spp. samples available for the study were retrospectively analyzed. The system Vitek-Biomerieux with Candida identification card is recommended for laboratory routine use and presents 80.6% agreement with the reference method. By separate analysis of species, 13.5% of C. parapsilosis samples differed from the reference method, while the Vitek system wrongly identified them as C. tropicalis, C....
