The present study was aimed at reducing the time and labour used to perform DNA-DNA hybridizations for classification of bacteria at the species level. A micro-well-format DNA hybridization method was developed and validated. DNA extractions were performed by a small-scale method and DNA was sheared mechanically into fragments of between 400 and 700 bases.(More)
Bacteria of the avian [Pasteurella haemolytica]-'Actinobacillus salpingitidis' complex have been associated with different pathological conditions in birds, among which salpingitis and peritonitis in chickens of layer type seem to dominate. The aim of this study was to classify these bacteria by comparison of 37 strains tentatively classified as biovars of(More)
The aim of this study was to improve the definition and identification of a group of veterinarily important bacteria referred to as the [Pasteurella] aerogenes-[Pasteurella] mairii-[Actinobacillus] rossii complex. These organisms have mainly been isolated from the reproductive and intestinal tracts of pigs and in most cases have been considered as(More)
OBJECTIVES Doripenem is a new carbapenem recently introduced into Europe. The COMParative Activity of Carbapenem Testing (COMPACT) study compared the susceptibility of common Gram-negative bacilli causing serious infections in hospitalized patients with doripenem, imipenem and meropenem. METHODS Gram-negative isolates (4498 total: 2171 Pseudomonas(More)
We analysed the effect of intraperitoneal insufflated ozonized oxygen on the anaesthetic strength generated by tribromoethanol, ketamine/xylazine, chloral hydrate, pentobarbital, and urethane in male Wistar rats. High dosages of anaesthetic drugs normally used for deep surgical anaesthesia were injected. The ozonized oxygen gas mixture was given five times(More)
INTRODUCTION Clostridium difficile infection (CDI) is the most common cause of health-care-associated infectious diarrhea. Recurrence rates are as high as 20-30% after standard treatment with metronidazole or vancomycin, and appear to be reduced for patients treated with fidaxomicin. According to the literature, the risk of CDI recurrence increases after(More)
AIM The oropharyngeal flora is of importance for the development of oral mucositis, which is a frequent complication in oncologic practice. It also plays a role in the pathogenesis of ventilator-associated pneumonia. Mucositis is associated with significantly worse clinical and economic outcomes. The aim of our study was to assess the efficacy of(More)
OBJECTIVE To characterise eight isolates of a Gram-negative organism obtained from the upper respiratory tract of cattle showing evidence of mild upper respiratory tract disease. DESIGN The isolates were compared with the five recognised species within the genus Mannheimia - M haemolytica, M glucosida, M granulomatis, M ruminalis and M varigena--using a(More)
