Cost comparison of commonly used postoperative topical ophthalmic antibiotics.

Purpose: To provide information on the actual fill level and cost of currently available antibiotic drops used perioperatively.

Design: Prospective laboratory investigation.

Setting: Robert Cizik Eye Clinic, Houston, Texas USA.

Sixteen-year experience with the Putterman-Gladstone tube for conjunctival dacryocystorhinostomy.

Purpose: To determine whether the Putterman-Gladstone tube is a safe and effective lacrimal bypass tube in conjunctival dacryocystorhinostomy surgery.

Methods: The authors retrospectively reviewed the charts of patients who underwent conjunctival dacryocystorhinostomy with the Putterman-Gladstone tube between January 1994 and December 2010. Clinical data reviewed included demographics, ocular and surgical history, epiphora symptoms, complications, and repeat surgery information.

Comparison of an indirect immunofluorescence assay, western blot analysis, and a commercially available ELISA for detection of Ehrlichia canis antibodies in canine sera.

Objective: To examine the correlation between results for an indirect immunofluorescence assay (IFA) that uses Ehrlichia canis antigen as a substrate (ie, E canis-IFA), 2 western blot (WB) analyses, and a commercially available ELISA in the detection of E canis antibody in dog sera.

Sample Population: 54 canine serum samples that were reactive on E canis-IFA and 16 canine serum samples that were E canis-IFA nonreactive.

Procedure: Serum samples were evaluated by use of 2 WB analyses and a commercially available ELISA.

Two novel strains of Bacillus thuringiensis toxic to coleopterans.

Two novel strains of Bacillus thuringiensis were isolated from native habitats by the use of genes coding for proteins toxic to coleopterans (cryIII genes) as hybridization probes. Strain EG2838 (isolated by the use of the cryIIIA probe) contained a cryIIIA-hybridizing plasmid of approximately 100 MDa and synthesized crystal proteins of approximately 200 (doublet), 74, 70, 32, and 28 kDa. Strain EG4961 (isolated by the use of a cryIIIA-related probe) contained a cryIIIA-hybridizing plasmid of approximately 95 MDa and synthesized crystal proteins of 74, 70, and 30 kDa.

Amino acid sequence and entomocidal activity of the P2 crystal protein. An insect toxin from Bacillus thuringiensis var. kurstaki.

The gene encoding the 66-kDa entomocidal protein (P2 protein or mosquito factor) from Bacillus thuringiensis var. kurstaki has been isolated by the use of a 62-mer oligonucleotide probe that encoded 21 amino acids of the P2 protein NH2 terminus. The DNA sequence of the gene, designated cryBI, was unique from the published sequences of other B.
