CTX-M-15-producing Enteroaggregative Escherichia coli as Cause of Travelers' Diarrhea. Travelers' diarrhea is a major public health problem. From patients in whom diarrhea developed after travel to India, 5 enteroaggregative Escherichia coli strains carrying β-lactamase CTX-M-15 were identified; 3 belonged to clonal complex sequence type 38. This β-lactamase contributes to the multidrug resistance of enteroaggregative E. coli, thereby limiting therapeutic alternatives.

Laboratory investigation of diarrhea in travelers to Mexico: evaluation of methods for detecting enterotoxigenic Echerichia coli. A laboratory investigation was conducted on cultures collected from travelers before, during, and after a trip to Mexico to characterize the etiology of traveler'sdiarrhea. Four laboratory methods for detecting enterotoxigenicity of Escherichia coli were evaluated: the infant mouse assay, the Chinese hamster ovary (CHO) cell assay, the Y1 adrenal cell assay (...) , and the rabbit ileal loop. Although a number of common enteric pathogens were identified as a cause of traveler'sdiarrhea, including six serotypes of Salmonella, two serotypes of Shigella, Vibrio parahaemolyticus, Giardia lamblia, and Entamoeba histolytica, enterotoxigenic Escherichia coli was most commonly isolated. Strains were identified that produced only heat-labile enterotoxin (LT), only heat-stable enterotoxin (ST), or both LT and ST. The infant mouse assay yielded results falling into two distinct

Travelers' Diarrhea On the average, one-fourth of North Americans visiting developing countries experience a self-limited diarrheal illness that interferes with holiday or business activities. Recent work suggests that these episodes are caused by a small inoculum of enteropathogenic Escherichia coli which are common in the country visited and rare in the country of origin. Neither antimicrobial treatment nor anti-diarrheal agents have proven benefit once the illness has begun. Despite its (...) frequent use, iodochlorhydroxyquin has not been shown in double blind studies to be effective as a preventive agent, and may be dangerous. The status of furazolidone for prevention of tourist diarrhea is questionable. Both neomycin sulfate and phythalylsulfathiazole have demonstrated efficacy as chemoprophylactics in Mexico. However, their use should be restricted to limited types of travel and travelers. General admonitions concerning avoidance of certain ingestibles are recommended; despite

Effect of a lactobacilli preparation on traveler'sdiarrhea. A randomized, double blind clinical trial. The effectiveness of prophylactic ingestion of a commercial preparation of lactobacilli (Lactinex) for the prevention or modification of traveler'sdiarrhea was tested in a randomized double blind clinical trial in 50 volunteer travelers to Mexico from the United States. Twenty-six subjects received the lactobacilli preparation and 24 received placebo. The incidence of diarrhea and its (...) duration during the 4 weeks of observation were quite similar for the two preparations: 35% for lactobacilli-treated subjects and 29% for placebo subjects. Typically, the diarrhea was mild, lasting 2 days. From the observations during this study we conclude that prophylactic ingestion of lactobacilli for 1 week does not reduce the incidence or duration of traveler'sdiarrhea either during the period of ingestion or during the following 3 weeks.
Prophylactic doxycycline for travelers' diarrhea: results of a prospective double-blind study of Peace Corps volunteers in Morocco. A second randomized double-blind study to determine the efficacy of doxycycline, 100 mg daily, for the prevention of travelers' diarrhea was carried out among 50 Peace Corps Volunteers during their first 10 wk in Morocco. The volunteers took either doxycycline or placebo for 3 wk, and were observed for an additional 7 wk. Eleven of 24 taking the placebo and 2 of 26 (...) taking doxycycline had travelers' diarrhea during the treatment period (P less than 0.01). One week after cessation of the doxycycline, however, persons in that group developed an increase in frequency of travelers' diarrhea (P less than 0.05) so that by 3 wk after the drug was stopped, there were no differences between groups. Enterotoxigenic E. coli, most of which were sensitive to doxycycline, were the most frequently isolated pathogens during the entire study. This study corroborates

In doing the metagenomic sequencing, they limited their assessment to genes conferring verified resistance phenotypes (i.e., those genes known to be associated with resistant bacterial infections). 69% (12 of 17 going to Central Africa and 12/18 to the Indian peninsula) had travelers’ diarrhea for a median of 4 days. None were exposed to antibiotic treatment in the 6-month period before or during the travel, though those who

Tropical and travel-associated norovirus: current concepts. We highlight recent advances relevant to understanding norovirus infections in the tropics, both in populations living in developing settings and travelers to these regions.Because of the decrease in diarrheal disease associated with the global rollout of vaccines against rotavirus, norovirus is emerging as the predominant cause of diarrhea morbidity among children in the tropics, and evidence suggests that it contributes to adult (...) disease in endemic populations and travelers. In addition to identifying potential target populations for preventive measures, we provide an update on norovirus vaccine development and concepts related to their implementation in low-income and middle-income countries.These current concepts related to norovirus-attributable disease burden, clinical significance, and economic impact can potentially be applied to tailoring efforts to prevent and mitigate the effects of this important enteropathogen.
(43%), Americas (21%), and Africa (17%). Doctors' and travelers' surveys showed variable levels of concordance: 94% of patients recalled discussion of malaria, 84% rabies, and 76% dengue. For malaria, 95% remembered discussions regarding insect repellents, and 92% recalled that medical advice should be sought if fever developed. For travelers with whom rabies was discussed, 94% recalled that medical advice must be urgently sought following a bite/scratch. For travelers' diarrhea (TD), 99% knew (...) Immediate Recall of Health Issues Discussed During a Pre-Travel Consultation. An important role of pre-travel consultations is to improve travelers' understanding of travel-related diseases, but the efficacy of education provided is unknown. This study sought to assess recall and knowledge immediately following a pre-travel consultation.The study was conducted at a hospital-based pre-travel clinic in Melbourne, Australia. Travelers aged ≥16 years seen between September 2010 and March 2012 were
travelers (0.5%) acquired carbapenemase-producing Enterobacteriaceae. The acquisition rate was higher in Asia (142/196 [72.4%]) than in sub-Saharan Africa (93/195 [47.7%]) or Latin America (57/183 [31.1%]). MRE acquisition was associated with the type of travel, diarrhea, and exposure to β-lactams during the travel. Three months after return, 4.7% of the travelers carried MRE. Carriage lasted longer in travelers returning from Asia and in travelers with a high relative abundance of MRE at return.MRE (...) High rate of acquisition but short duration of carriage of multidrug-resistant Enterobacteriaceae after travel to the tropics.
