Clinicopathologic findings in dogs seroreactive to Bartonella henselae antigens.

Objective: To assess the potential clinical relevance of seroreactivity to Bartonella henselae antigens in dogs.

Animals: 40 dogs seroreactive to B henselae and 45 dogs that did not seroreact to B henselae.

Procedure: A case-control study was conducted.

Fetal and adult human oligodendrocyte progenitor cell isolates myelinate the congenitally dysmyelinated brain.

Both late-gestation and adult human forebrain contain large numbers of oligodendrocyte progenitor cells (OPCs). These cells may be identified by their A2B5(+)PSA-NCAM(-) phenotype (positive for the early oligodendrocyte marker A2B5 and negative for the polysialylated neural cell adhesion molecule). We used dual-color fluorescence-activated cell sorting (FACS) to extract OPCs from 21- to 23-week-old fetal human forebrain, and A2B5 selection to extract these cells from adult white matter.

Endoscopic evaluation of the esophagus and stomach in three loggerhead sea turtles (Caretta caretta) and a Malaysian giant turtle (Orlitia borneensis).

Three loggerhead sea turtles (Caretta caretta) and a Malaysian giant turtle (Orlitia borneensis) were presented with suspected or confirmed esophageal foreign bodies. Esophagoscopy was performed on all turtles, and gastroscopy was performed on three turtles. In all cases, endoscopy was easy to perform, and allowed visualization of most upper gastrointestinal features.

Molecular identification of Ehrlichia ewingii infection in dogs: 15 cases (1997-2001).

Objective: To determine historical, physical examination, hematologic, and serologic findings in dogs with Ehrlichia ewingii infection.

Design: Retrospective study.

Animals: 15 dogs.
