Acute diarrhoeal diseases remain a leading cause of global morbidity and mortality particularly among young children in resource-limited countries. Recent large studies utilizing case-control design, prospective sampling and more sensitive and broad diagnostic techniques have shed light on particular pathogens of importance and highlighted the previously under recognized impact of these infections on post-acute illness mortality and growth. Vaccination, particularly against rotavirus, has emerged as a key effective means of preventing significant morbidity and mortality from childhood diarrhoeal disease...

Background: Laribacter hongkongensis is a facultative anaerobic, non-fermentative, Gram-negative bacillus associated with community-acquired gastroenteritis and traveller's diarrhoea. No clinical MDR L. hongkongensis isolate has been reported yet. Methods: We performed WGS (PacBio and Illumina) on a clinical L. hongkongensis strain HLGZ1 with an MDR phenotype. Results: HLGZ1 was resistant to eight classes of commonly used antibiotics. Its complete genome was a single circular chromosome of 3 424 272 bp with a G + C content of 62...

Batel Nissan, Tamar Lachish, Eli Schwartz
Background: Persistent abdominal symptoms (PAS) are common among returning-travellers. In the absence of sensitive tests to identify intestinal parasites, gastrointestinal (GI) symptoms often remain a diagnostic challenge. In this study we examined the effectiveness of empirical anti-parasitic treatment in returning-travellers with PAS despite no positive stool-test. Methods: A retrospective study among returning travellers who approached the clinic between the years 2014 and 2016 with GI complaints without a positive stool-test...

We report a case of ileo-colonic Histoplasmosis without apparent respiratory involvement in a patient who had previously undergone an orthotopic liver transplant (OLT) for primary biliary cholangitis 15 years earlier. The recipient lived in the United Kingdom, a non-endemic region for Histoplasmosis. However, she had previously lived in rural southern Africa prior to her OLT. The patient presented with iron deficiency anaemia, diarrhoea, abdominal pain and progressive weight loss. She reported no previous foreign travel, however, it later became known that following her OLT she had been on holiday to rural southern Africa...

Enterotoxigenic Escherichia coli (ETEC) infections are an important cause of diarrhoea among young children living in low- and middle-income countries and visiting travellers. The development of effective vaccines is complicated by substantial genomic diversity that exists among ETEC isolates. To investigate how ETEC genomic variation is reflected at expressed proteome level, we applied label-free quantitative proteomics to 7 human ETEC strains representing 5 epidemiologically important lineages. We further determined the proteome profile of the non-pathogenic E...

REVIEW

BACKGROUND: Enterobacteriaceae have become increasingly resistant, especially due to the acquisition and spread of extended-spectrum beta-lactamases (ESBLs), which confer resistance to the majority of beta-lactams. Multi-resistant Enterobacteriaceae (MRE) were first isolated in hospitals, but now they are disseminating in the community setting, mostly in low and middle income countries. Consequently, the increasing number of international travels leads to the importation of MRE from high-prevalence to low-prevalence countries...

OBJECTIVES: Eighty million travellers visiting (sub)tropical regions contract travellers' diarrhoea (TD) each year, yet prospective data comparing the prevalence of TD pathogens in various geographical regions are scarce. Our recent study employing modern molecular methods found enteropathogenic (EPEC) and enteroaggregative (EAEC) Escherichia coli to be the most frequent pathogens, followed by enterotoxigenic E. coli (ETEC) and Campylobacter. We revisited our data to compare the findings by geographical region...

Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhoea in children below 5 years of age in endemic areas, and is a primary cause of diarrhoea in travellers visiting developing countries. Epidemiological analysis of E. coli pathovars is traditionally carried out based on the results of serotyping. However, genomic analysis of a global ETEC collection of 362 isolates taken from patients revealed nine novel O-antigen biosynthesis gene clusters that were previously unrecognized, and have collectively been called unclassified...

AIM: to explore experiences of stigma in people with inflammatory bowel disease. BACKGROUND: Diarrhoea, urgency and incontinence are common symptoms in inflammatory bowel disease. Social rules stipulate full control of bodily functions in adulthood: poor control may lead to stigmatisation, affecting patients' adjustment to disease. Disease-related stigma is associated with poorer clinical outcomes but qualitative evidence is minimal. DESIGN: An interpretive (hermeneutic) phenomenological study of the lived experience of stigma in inflammatory bowel disease...

Introduction.Vibrio vulnificus (V. vulnificus) causes a severe infection that develops in the compromised host. Its pathophysiology is classified into three types: (1) primary septicaemia, (2) gastrointestinal illness pattern and (3) wound infection pattern. Of these, primary septicaemia is critical. V. vulnificus can be classified into three biotypes and two genotypes and its pathogenicity is type-dependent. Case presentation. A 47-year-old man presented to a local hospital with chief complaints of fever, bilateral lower limb pain and diarrhoea...

Background: Diarrhoea is a common medical problem affecting travellers to Asia, Africa and Latin America. The use of prophylactic antimicrobial agents may increase the risk of contracting resistant bacteria. Findings indicate that oligosaccharides, i.e. carbohydrate chains of 3-10 monosaccharides, reduce the risk of diarrhoea. Methods: We performed a placebo-controlled, double-blind study of a galacto-oligosaccharide, B-GOS (Bimuno®, Clasado Ltd, Milton Keynes UK), vs placebo for participants travelling to countries with a high/intermediate risk of diarrhoea for 7-15 days...

Background: Travellers' diarrhoea is the most common health problem in travellers. Depending on the region visited, up to 40% of travellers develop diarrhoea during a 2-week trip. The aim of this study was to assess risk factors for TD among travellers to the Indian subcontinent. Methods: An observational prospective multicentre cohort study investigated travellers to the Indian subcontinent. Participants completed questionnaires assessing the incidence of travellers' diarrhoea and identifying potential risk factors...

Background: Gap year travellers can potentially be exposed to many infectious diseases and other travel-related health problems including injuries and psychological problems. Currently, there is little information on health and wellbeing of this particular group of travellers. Methods: Participants were recruited from an organization that specialized in organising international gap year placements. Gap year travellers were asked to complete a pre-departure survey on demographics, placement destination and duration, previous travel experience, hobbies, risk taking behaviour, anticipated problems during the placement, and pre-travel preparations...

Introduction: As international travel increases, travellers may be at increased risk of acquiring infectious diseases not endemic in their home countries. Many journal articles and reference books related to travel medicine cite that between 22-64% of international travellers become ill during or after travel; however, this information is minimal, outdated and limited by poor generalizability. We aim to provide a current and more accurate estimate of the proportion of international travellers who acquire a travel-related illness...

Background: Understanding and detecting imported diseases is a priority in the prevention and management of prevalent and emergent infectious diseases acquired abroad. The +Redivi network measures the burden of imported infections in Spain and is essential for closing the gap in travel medicine. Methods: Demographic characteristics, travel information, syndromes and confirmed travel-related diagnoses were registered in a standardised online database. Results: A total of 10 767 cases of imported infectious diseases were registered between October 2009 and December 2015...

Background: The recommendation that antibiotics should be used for routine therapy of travellers' diarrhoea is being reconsidered in view of growing evidence that the therapy may lead to intestinal carriage of multi-drug resistant (MDR) colonic microbiota. This review attempts to put the issues of therapy and MDR acquisition in perspective to help in the establishment of therapeutic recommendations for travellers' diarrhoea. Methods: The existing literature showing the risk and consequences of acquisition of MDR microbiota in antibiotic-treated travellers was reviewed...

BACKGROUND: Cholera outbreaks are recurrent in Cameroon and despite the efforts put together during epidemics, they are always associated with a high case fatality. Inadequate demand for health care is one of the major factors that might be responsible for the high case fatality. This study was conducted to describe the health seeking behaviour of suspected cases of cholera in four health districts of the Far North Cameroon. METHODS: We conducted a health facility based descriptive study involving suspected cases of cholera received in health facilities...

BACKGROUND: Limited prospective data are available on the acquisition of viral, bacterial and parasitic diarrhoeagenic agents by healthy individuals during travel. METHODS: To determine the frequency of travel associated acquisition of 19 pathogens in 98 intercontinental travellers, qPCR was used to detect 8 viral pathogens, 6 bacterial enteric pathogens and 5 parasite species in faecal samples collected immediately before and after travel. RESULTS: We found high pre-travel carriage rates of Blastocystis spp...
