چکیده

The partial 16S rRNA sequence of an unknown bacterium that was originally isolated from middle ear fluids of children with persistent otitis media was determined by reverse transcription. A comparison of this sequence with sequences from other gram-positive species having low guanine-plus-cytosine contents revealed that this bacterium represents a new line of descent, for which the name Alloiococcus otitis gen. nov., sp. nov., is proposed. The type strain is strain NCFB 2890.

Allofustis seminis gen. nov., sp. nov., a novel Gram-positive, catalase-negative, rod-shaped bacterium from pig semen.

An unknown Gram-positive, catalase-negative, facultatively anaerobic, non-spore-forming, rod-shaped bacterium originating from semen of a pig was characterized using phenotypic, molecular chemical and molecular phylogenetic methods. Chemical studies revealed the presence of a directly cross-linked cell wall murein based on L-lysine and a DNA G + C content of 39 mol%. Comparative 16S rRNA gene s...

A Remarkable New Family of Jurassic Insects (Neuroptera) with Primitive Wing Venation and Its Phylogenetic Position in Neuropterida

BACKGROUND Lacewings (insect order Neuroptera), known in the fossil record since the Early Permian, were most diverse in the Mesozoic. A dramatic variety of forms ranged in that time from large butterfly-like Kalligrammatidae to minute two-winged Dipteromantispidae. PRINCIPAL FINDINGS We describe the intriguing new neuropteran family Parakseneuridae fam. nov. with three new genera and 15 new ...

One third of middle ear effusions from children undergoing tympanostomy tube placement had multiple bacterial pathogens

BACKGROUND Because previous studies have indicated that otitis media may be a polymicrobial disease, we prospectively analyzed middle ear effusions of children undergoing tympanostomy tube placement with multiplex polymerase chain reaction for four otopathogens. METHODS Middle ear effusions from 207 children undergoing routine tympanostomy tube placement were collected and were classified by ...

Taxonomic notes on the spider genus Messapus Simon, 1898 (Araneae, Corinnidae), with the description of the new genera Copuetta and Wasaka and the first cladistic analysis of Afrotropical Castianeirinae.

The Afrotropical sac spider genus Messapus Simon, 1898, presently placed in the Castianeirinae, is reviewed. The type material of the type species, M. martini Simon, 1898, clearly represents two different species, a corinnine female (here designated the lectotype) and a castianeirine male (the paralectotype). The female is redescribed and its corresponding male is described for the first time. ...
