Ethnopharmacological Relevance: Extracts from Cranberry fruits (Vaccinium macrocarpon) are traditionally used against urinary tract infections, mainly due to antiadhesive activity against uropathogenic E. coli (UPEC), but the exact mode of action and compounds, responsible for the activity, are unknown.

Aim Of The Study: i.

Specific recognition and bacterial adhesion to host cells by uropathogenic Escherichia coli (UPEC) are the first steps towards infection of epithelial tissue of the human urogenital system. Therefore, targeting of UPEC virulence factors, relevant for adhesion, is a promising approach for prevention of recurrent urinary tract infections (UTI). A fully characterized plant-derived aqueous extract from the leaves of Orthosiphon stamineus (OWE), a plant traditionally used in clinical practice in Europe and Asia for UTI, has been shown to exert strong antiadhesive effects under in vitro and in vivo conditions.

Pathogens rely on a complex virulence gene repertoire to successfully attack their hosts. We were therefore surprised to find that a single fimbrial gene reconstitution can return the virulence-attenuated commensal strain Escherichia coli 83972 to virulence, defined by a disease phenotype in human hosts. E.

It would be desirable to have an unambiguous scheme for the typing of Shiga toxin-producing (STEC) isolates to subpopulations. Such a scheme should take the high genomic plasticity of into account and utilize the stratification of STEC into subgroups, based on serotype or phylogeny. Therefore, our goal was to identify specific marker combinations for improved classification of STEC subtypes.

Asymptomatic bacterial colonization of the urinary bladder (asymptomatic bacteriuria, ABU) can prevent bladder colonization by uropathogens and thus symptomatic urinary tract infection (UTI). Deliberate bladder colonization with ABU isolate 83972 has been shown to outcompete uropathogens and prevent symptomatic UTI by bacterial interference. Many ABU isolates evolved from uropathogenic ancestors and, although attenuated, may still be able to express virulence-associated factors.

Article Synopsis
  • Asymptomatic bacteriuria (ABU) involves bacteria living in the urinary bladder without causing any symptoms or disease in the host.
  • ABU may help prevent future urinary tract infections by outcompeting harmful bacteria.
  • The study presents whole-genome sequences of nine ABU isolates specifically from diabetic patients for further research and understanding.

This study reports data from a larger number of cases of triceps tendon disruption. Records from 10 veterinary referral hospitals between 2003 and 2014 were searched for canine and feline cases diagnosed with triceps tendon disruption, based on orthopaedic examination confirmed during surgery. Long-term follow-up and owner satisfaction were assessed using a questionnaire.

The objective of this study was to assess the variables associated with complications of total hip replacement (THR) and report owner-assessed outcomes. Entries into the British Veterinary Orthopaedic Association-Canine Hip Registry (BVOA-CHR) between September 2011 and December 2012 were reviewed separately and in conjunction with previous data (January 2010-August 2011). An outcomes assessment questionnaire was used to collect data from owners.

Asymptomatic bacteriuria (ABU) is a bacterial carrier state in the urinary tract that resembles commensalism at other mucosal sites. ABU strains often lack the virulence factors that characterize uropathogenic Escherichia coli (E. coli) strains and therefore elicit weak innate immune responses in the urinary tract.

Objective: To investigate the mechanical characteristics of a nontoxic, low-cost, rigid polymer (RP) and to compare the structural and mechanical properties of a full-frame external skeletal fixator (ESF) with either RP connecting bars, polymethylmethacrylate (PMMA) connecting bars, or stainless-steel (SS) clamps and connecting bars.

Study Design: In vitro mechanical evaluation.

Methods: Mechanical properties were assessed using an in vitro bone fracture model with a bilateral uniplanar ESF (type II).

Aortic and cardiac mineralization was found in 21 of 3443 (0.61%) canine thoracic radiographs. In none of 786 feline thoracic radiographs reviewed were such lesions present.
