Rise in Possible Fluoroquinolone-Resistant Shigella Isolates Rise in Possible Fluoroquinolone-Resistant Shigella Isolates

The CDC is seeing an increasing number of Shigella isolates that test within the susceptible range for the fluoroquinolone antibiotic ciprofloxacin but harbor one or more resistance mechanisms.Medscape Medical News

Authors: Casanovas-Moreno-Torres I, Gutiérrez-Soto B, Modovan TD, Expósito-Ruiz M, Navarro-Marí JM, Gutiérrez-Fernández J Abstract The activity of azithromycin against enteritis-producing agents other than Campylobacter spp. was studied. The susceptibility to azithromycin, through gradient test, of 88 clinical isolates (51 Salmonella spp., 23 Aeromonas spp., 10 Shigella sonnei and 4 Yersinia enterocolitica) for one year was studied prospectively. The results were compared with the activity of ampicillin, trimethoprim-sulfamethoxazole and ciprofloxacin by microdilution. For azithro...

Conclusions: Our data has uncovered a prolonged clonal outbreak of ESBL S. sonnei that was likely first introduced by returned travellers and has subsequently been circulating locally in Australia. The emergence of a local outbreak of ESBL S. sonnei, with a multidrug-resistant profile, including reduced susceptibility to ciprofloxacin, represents a significant public health threat.

lm AM, Dudley EG Abstract The 3rd E. coli and the Mucosal Immune System (ECMIS) meeting was held at Ghent University in Belgium from June 2-5, 2019. It brought together an international group of scientists interested in mechanisms of colonization, host response, and vaccine development. ECMIS distinguishes itself from related meetings on these enteropathogens by providing a greater emphasis on animal health and disease, and covering a broad range of pathotypes including enterohemorrhagic, enteropathogenic, enterotoxigenic, enteroaggregative, and extraintestinal pathogenic E. coli As it is well-established that the...

Activation of the NLRP3 inflammasome requires the expression of NLRP3, which is strictly regulated by its capacity to directly recognize microbial-derived substances. Even though the involvement of caspase-1 activation in macrophages via NLRP3 and NLRC4 has been discovered, the accurate mechanisms by which Shigella infection triggers NLRP3 activation remain inadequately understood. Here, we demonstrate that IpaH4.5, a Shigella T3SS effector, triggers inflammasome activation by regulating NLRP3 expression through the E3 ubiquitin ligase activity of IpaH4.5. First, we found that IpaH4.5 interacted with NLRP3. As a result, Ip...

Multidrug-resistant bacteria are among the most important current threats to public health. Typically, they are associated with nosocomial infections. However, some have become prevalent causes of community-acquired infections, such as Neisseria gonorrhoeae, Shigella, Salmonella, and Streptococcus pneumoniae. The community spread of multidrug-resistant bacteria is also a crucial development. An important global threat on the horizon is represented by production of carbapenemases by community-acquired hypervirulent Klebsiella pneumoniae. Such strains have already been found in Asia, Europe, and North America. Prevention of ...

The bacteriological diagnosis of intestinal bacterial infections has historically been based on culture on agar plates. However, culture may lack sensitivity, and some enteropathogens, such as pathovars of Escherichia coli, may escape routine diagnosis. Our goal was to evaluate the analytical performance of the Novodiag Bacterial GE+ kit for the detection of enteropathogenic bacteria in acute community diarrhea. We included 251 stools in this study (198 retrospective and 53 prospective). The analytical performance was calculated using a composite reference standard (CRS) in the absence of a perfect gold standard (lack of s...

kungo Public schools in most rural areas of South Africa depend on untreated groundwater due to unreliable water supply by the municipalities. This has the potential to cause water-related health problems to school children. Temperature, pH, and electrical conductivity (EC) were measured in situ. Chemical (fluoride, chloride, sulphate, phosphate, nitrate, magnesium, calcium, sodium, and potassium) and microbial (Escherichia coliform (E. coli), Salmonella typhimurium, and Shigella flexneri) water quality parameters were analysed in groundwater samples from 10 public schools in Vhuronga 1 to determine suitability for use...

Abstract The U.S. military personnel must be ready to deploy to locations worldwide, including environments with heightened risk of infectious disease. Diarrheal illnesses continue to be among the most significant infectious disease threats to operational capability. To better prevent, detect, and respond to infectious disease threats and improve synchronization across the Department of Defense (DoD) overseas laboratory network, a multisite Global Travelers' Diarrhea protocol was implemented with standardized case definitions and harmonized laboratory methods to identify enteric pathogens. Harmonized laboratory pr...
