Two hundred twenty-four isolates of Bacteroides sp. were recovered from recurrently inflamed tonsils, infected peritoneal fluid, abscesses, wounds, and burns of hospitalized children. Isolates were examined for beta-lactamase production by the chromogenic cephalosporin analog 87/312 methodology. Altogether, 119 isolates were beta-lactamase producers. Of these, 53 were in the B. fragilis group, ...

INTRODUCTION The standard anatomical description of the extensor pollicis brevis tendon provided in textbooks of anatomy is at odds with that of published anatomical studies. It is crucial to the hand surgeon that he or she has a clear understanding of its anatomy, including its variations. The aim of this study was to provide a comprehensive review of the current literature on the anatomy and ...

BACKGROUND Algal blooms of Karenia brevis, a harmful marine algae, occur almost annually off the west coast of Florida. At high concentrations, K. brevis blooms can cause harm through the release of potent toxins, known as brevetoxins, to the atmosphere. Epidemiologic studies suggest that aerosolized brevetoxins are linked to respiratory illnesses in humans. OBJECTIVES We hypothesized a relat...

Gram positive aerobic or facultatively anaerobic spore forming gram positive bacilli were first identified by Christian Gottfried Ehrenberg in 1885 and were later classified by Ferdinand Cohn in to a separate genus Bacillus [1]. Aerobic spore forming gram positive bacteria are commonly referred to as ASB’s and includes members of Bacillus spp which are basically saprophytes living as thermophil...

The brevetoxin-producing dinoflagellate, Karenia brevis, forms nearly annual blooms off the Florida west coast, severely impacting the region's ecology and economy. Bacteria are often cited as either promoting or interfering with the development of algal blooms, and thus a detailed study of the bacterioplankton assemblages associated with K. brevis was undertaken. We developed sixteen 16S rRNA ...

Lactobacillus brevis ATCC367 was engineered to express pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH) genes in order to increase ethanol fermentation from biomass-derived residues. First, a Gram-positive Sarcina ventriculi PDC gene (Svpdc) was introduced into L. brevis ATCC 367 to obtain L. brevis bbc03. The SvPDC was detected by immunoblot using an SvPDC oligo peptide antiserum, ...

Concomitant avulsion fractures of the extensor carpi radialis longus and brevis tendons are relatively rare injuries. The usual injury mechanism is forced hyperflexion to an actively extended wrist. No consensus exists regarding the appropriate management of this injury, with some surgeons advocating closed treatment and others favoring operative fixation. The authors describe a novel surgical ...

Clinical disease caused by Empedobacter brevis (E. brevis) is very rare. We report the first case of E. brevis bacteremia in a patient with HIV and review the current literature. A 69-year-old man with human immunodeficiency virus (HIV) and CD4 count of 319 presented with chief complaints of black tarry stools, nausea and vomiting for 2 days. Physical exam was significant for abdominal pain on ...

Competition is a major force structuring marine planktonic communities. The release of compounds that inhibit competitors, a process known as allelopathy, may play a role in the maintenance of large blooms of the red-tide dinoflagellate Karenia brevis, which produces potent neurotoxins that negatively impact coastal marine ecosystems. K. brevis is variably allelopathic to multiple competitors, ...

The branched chain amino acid aminotransferase [EC 2.6.1.42] was purified to a homogeneous state from a gramicidin S-producing strain of Bacillus brevis. The enzyme had a molecular weight of about 93,000 and consisted of two identical subunits, each with a molecular weight of about 47,000. One pyridoxal phosphate is bound per subunit. In addition to branched chain amino acids, the enzyme uses L...
