Here, we present 20 draft genome sequences of Clostridium botulinum type A isolates originating from foodborne outbreaks in the United States and Ethiopia. Publicly available genomes enhance our understanding of C. botulinum genomics and are an asset in bioterrorism preparedness.

During September 2019, public health authorities in El Paso County, Colorado, were notified of four patients who had presented to nearby hospitals with clinical features consistent with botulism, a paralytic illness caused by botulinum neurotoxin. One patient died soon after presentation; the other three patients required intensive care but recovered after receiving botulism antitoxin. Botulinum toxin type A was detected in serum from all patients.

Objective: To describe the epidemiology of laboratory-confirmed Diarrhoeagenic Escherichia coli (DEC) cases from active facility-based surveillance in Guatemala.

Methods: We collected clinical and risk factor data on enrolled patients (aged 0-52 years) with acute diarrhoea at government healthcare facilities (1 hospital and 6 clinics) in Santa Rosa, Guatemala, during 2008-2009 and 2014-2015. Stool samples were analysed, E.

Article Synopsis
  • Public Health Laboratories (PHLs) in Puerto Rico suffered significant damage from Hurricane Maria, becoming inoperable immediately after the storm.
  • A quality management system (QMS) approach was adopted, starting in October 2017 and concluding in May 2018, successfully restoring 92% of the original laboratory testing capacity.
  • The lessons learned from this recovery effort are shared as valuable resources for other jurisdictions to improve their public health emergency preparedness.

To assess the spectrum of illness from toxigenic Vibrio cholerae O1 and risk factors for severe cholera in Haiti, we conducted a cross-sectional survey in a rural commune with more than 21,000 residents. During March 22-April 6, 2011, we interviewed 2,622 residents ≥ 2 years of age and tested serum specimens from 2,527 (96%) participants for vibriocidal and antibodies against cholera toxin; 18% of participants reported a cholera diagnosis, 39% had vibriocidal titers ≥ 320, and 64% had vibriocidal titers ≥ 80, suggesting widespread infection. Among seropositive participants (vibriocidal titers ≥ 320), 74.

Background: Human polymerized hemoglobin (PolyHeme, Northfield Laboratories) is a universally compatible oxygen carrier developed to treat life-threatening anemia. This multicenter phase III trial was the first US study to assess survival of patients resuscitated with a hemoglobin-based oxygen carrier starting at the scene of injury.

Obesity is rapidly becoming the most important public health issue in USA and Europe. Roux-en-Y gastric bypass is now established as the gold standard for treating intractable morbid or super obesity. We reviewed the imaging findings following this surgery in 234 patients.

The policy of routine angiography (ANG) for all penetrating neck wounds results in a high rate of negative studies. The medical records of all patients who presented to Wishard Memorial Hospital and Methodist Hospital of Indiana with penetrating injuries to the neck from January 1992 to April 2001 were reviewed. All patients who were hemodynamically stable underwent four-vessel ANG to evaluate for vascular injury irrespective of findings on physical examination (PE).

The purpose of this study was to evaluate whether 1995 study conclusions influenced patient selection and subsequent survival and whether indications for emergency room thoracotomy (ERT) could be further limited on the basis of patient physiologic status. A retrospective review of patient demographics, physiologic status both at the scene and on arrival to the emergency room (ER), and survival was performed on those who underwent ERT from July 1995 to December 1999. Sixty-five patients underwent ERT for sustained gunshot wounds and 14 patients for stab wounds.
