Incorporating Time–Dose–Response Into Shigella flexneri and Shigella sonnei Outbreak Models
Shigellosis, or bacillary dysentery, is an acute enteric infection spread directly or indirectly through the fecal–oral route by the genus Shigella (Scallan et al. 2011, Heymann 2008). Shigella is a genus of gram-negative, nonmotile bacilli belonging to the family Enterobacteriaceae (WHO 2005, Jin et al. 2002), which includes four species, of which S. flexneri (serogroup B) and S. sonnei (serog...
متن کاملThe indirect haemagglutination test in dysentery caused by Shigella sonnei and Shigella flexneri.
The examination of cultures of stools is mostly used in establishing the diagnosis of bacillary dysentery. Agglutination, the most frequently used serological investigation, does not give reliable results and is therefore not generally used. The bacteriological examination of stools fails in a certain percentage of cases, irrespective of the mode of culture used. Particularly troublesome are ex...
متن کاملAntimicrobial resistance in Shigella flexneri and Shigella sonnei in Hong Kong, 1986 to 1995.
Three hundred and thirty-three Shigella isolates obtained in 1986 to 1995 were tested for their susceptibilities to 19 antimicrobial agents. Nalidixic acid resistance had emerged in 59.6% of Shigella flexneri isolates during 1994 to 1995, with all tested resistant isolates having the mutation in gyrA encoding the Ser-83 alteration. Multiresistance (resistance to four or more agents) was more co...
متن کاملClinical implications of reduced susceptibility to fluoroquinolones in paediatric Shigella sonnei and Shigella flexneri infections
OBJECTIVES We aimed to quantify the impact of fluoroquinolone resistance on the clinical outcome of paediatric shigellosis patients treated with fluoroquinolones in southern Vietnam. Such information is important to inform therapeutic management for infections caused by this increasingly drug-resistant pathogen, responsible for high morbidity and mortality in young children globally. METHODS ...
متن کاملAntimicrobial effect of spices and herbs on Shigella sonnei and Shigella flexneri.
Of 17 spices and herbs tested at 1% (wt/vol) in Mueller-Hinton (MH) agar, only cloves, thyme, oregano, allspice, basil, rosemary, and marjoram showed antimicrobial effects on Shigella. The MICs of thyme, oregano, basil, and rosemary (as determined by the agar dilution method) ranged from 0.5 to 1% (wt/vol) depending on the Shigella strain used. With the use of various combinations of temperatur...
