Experiments were focused on the prevention of diarrhoea in weaned piglets by means of enterotoxigenic strains of Escherichia coli (ETEC) with colonizing factors K88 (F4). The process of immunization consisted of intramuscular administration of ETEC strain bacterin one day prior to weaning and oral administration of a live culture of non-pathogenic E. coli strain containing colonizing factors (O...

But what if the deaf have their own language—not oral but signed—as rich and expressive as any oral language, and as suitable for discussing science, art, or any other topic? What if this language is central to an independent culture of the deaf, with its own history and traditions, its own art forms and poetry? The deaf would then have to be viewed not as sharing a common pathology, but as a l...

With the plasmid DNA from a clinical isolate of enterotoxigenic Escherichia coli (ETEC) H 10407 as template, PCR-mediated cloning of the sequence encoding the heat-labile toxin B subunit (L T -B) has been carried out. Then this sequence was recloned into the pTrc 99A and pET23a expression vectors to give the pJasmids pTRCLTB and pETLTB, respectively. After induction, the former plasmid provides...

Actinomycosis, a rather uncommon infection of the oral cavity, poses and unusual problem: recurrence. Primary or initial diagnosis of the disease is difficult and can be made easier only if the clinician bears in mind a few important facts: a previously compromised site is usually present, a slow, low-grade, almost painless infectious course is prevalent which tends to localize, and respond...

STUDY OBJECTIVES To identify factors predisposing cystic fibrosis (CF) patients to Stenotrophomonas maltophilia infection and to determine whether coinfection with S maltophilia affects the clinical response to therapy with tobramycin solution for inhalation (TSI), 300 mg bid. DESIGN Retrospective review of data collected from two identical, 6-month, randomized, placebo-controlled trials. S...

OBJECTIVES/HYPOTHESIS To determine the feasibility of viable storage of head and neck squamous cell carcinoma (HNSCC) for regrowth of cells in culture. STUDY DESIGN Laboratory-based translational study. METHODS Methods for intermediate-term frozen storage of viable HNSCC were explored using small pieces of primary tumor and dissociated HNSCC cells after short-term culture. Viable cells afte...

Background: Cyanoacrylate tissue adhesives have been used as a substitute to silk for intraoral wound closure. Placement of sutures provides a corridor for accumulation of microorganisms into tissue which leads to infection. Cyanoacrylate-based adhesives exhibit many properties of an ideal wound closure agent, minimizing the problems generated by suturing thread. The antimicrobial properties of...

OBJECTIVE To compare the short-term effectiveness of ceftriaxone single dose followed by cefixime with a standard treatment of acute uncomplicated pyelonephritis in women. METHODS An open, prospective, and randomised trial of women with acute uncomplicated pyelonephritis was performed. Group A were given a daily intravenous dose of 1 g ceftriaxone; group B: ceftriaxone 1 g intravenous single ...

Objectives Periodontal diseases are one of the common oral diseases and microbial oral flora is one major factor responsible for it. Elimination of periodontal pathogens is particularly important in managing the periodontal state. This study aimed to assess the antibacterial effects of Nanosil, chlorhexidine (CHX) and probiotic mouthwashes on periodontal pathogens. Methods In this in-vitro stu...
