Selection response to DNA testing for canine ceroid lipofuscinosis in Tibetan terriers.

A late onset form of canine ceroid lipofuscinosis (CCL) is prevalent in Tibetan terriers. The disease is inherited as a monogenic recessive trait caused by aberrant exon skipping in ATP13A2. The aim of the present study was to analyse the frequencies of this mutation in Tibetan terriers registered with the German club for Tibetan dog breeds (Internationaler Klub für Tibetische Hunderassen, KTR) from 1987 to 2012 and to determine responses to selection following the introduction of DNA testing in 2010.

Diversity in cytokine response to bacteria associated with preterm birth by fetal membranes.

Objective: This study compared cytokine and prostaglandin (PG) responses by fetal membranes stimulated with 4 different bacterial species associated with preterm birth (PTB).

Study Design: Fetal membranes (n = 13 from normal term cesarean sections [not in labor]) in an organ explant system were stimulated with heat-killed Ureaplasma parvum, Gardanerella vaginalis, Escherichia coli, group B Streptococcus (GBS), or lipopolysaccharide (LPS). Cytokines (interleukin [IL]-1beta, IL-6, IL-8, IL-10, tumor necrosis factor [TNF]-alpha, and interferon-gamma) and PG (PGF(2alpha) and PGE(2)) concentrations were quantitated and compared.
