Canine Pyometra: An Update on Pathogenesis and Treatment Washington State University–Pullman

Despite six decades of research, the pathogenesis of pyometra is still not completely understood. Recent investigations question whether the previous concept of considering cystic endometrial hyperplasia (CEH)–pyometra as a complex is correct. The pathogenesis of CEH appears to have a strong hormonal component, whereas the etiology of pyometra might be more influenced by the bacterial component...

Surgical uterine drainage and lavage as treatment for canine pyometra.

Pyometra is a common post-oestral syndrome in bitches. Classical treatment consists of either ovariohystorectomy or medical intervention. Surgical uterine drainage and lavage via direct trans-cervical catheterisation using a 5% povidone-iodine in saline solution was performed successfully in 8 bitches with pyometra. All bitches conceived and whelped without complications subsequent to this trea...

Selection of reference genes in canine uterine tissues.

Real-time quantitative polymerase chain reaction (RT-qPCR) is usually employed in gene expression studies in veterinary research, including in studies on canine pyometra. Canine pyometra is a common clinical disease in bitches. When using RT-qPCR, internal standards, such as reference genes, are necessary to investigate relative gene expression by quantitative measurements of mRNA levels. The a...

New Aspects of Canine Pyometra Studies on Epidemiology and Pathogenesis

Immunomodulation in the canine endometrium by uteropathogenic Escherichia coli

This study was designed to evaluate the role of E. coli α-hemolysin (HlyA) in the pathogenesis of canine pyometra, and on the immune response of canine endometrial epithelial and stromal cells. In Experiment 1, the clinical, hematological, biochemical and uterine histological characteristics of β-hemolytic and non-hemolytic E. coli pyometra bitches were compared. More (p < 0.05) metritis cases ...

Collagen and Glycosaminoglycan Profiles in the Canine Cervix during Different Stages of the Estrous Cycle and in Open- and Closed-Cervix Pyometra

The extracellular matrix of the cervix that comprises collagen, elastin, proteoglycans and glycosaminoglycans (GAGs) is thought to have an essential role in cervical relaxation. This study investigated the proportion of collagen and smooth muscle as well as the GAGs in cervices obtained from healthy bitches at different stages of the estrous cycle and bitches with open- and closed-cervix pyomet...
