INTRODUCTION The Shigella spp. is an organism with an ongoing changing resistance pattern to different antibiotics, thus making its appropriate treatment difficult. Nalidixic acid has been one of the most common agents used for the treatment of shigellosis. Recently, some studies have reported an emerging resistance to this agent. METHODS In this study, we compared the resistance of Shigella ...

Eleven infants aged 1-2 years suffering from shigellosis associated with Shigella flexneri type 6 were treated with rifampicin. All were initially treated with antimicrobial drugs to which Sh. flexneri was shown to be sensitive, but without effect. Rifampicin was effective in curing gastrointestinal symptoms and eradicating the bacilli in all infants in 5 days. The drug was given in a dose of 1...

The control of shigellosis in humans enjoys a prominent position in the history of bacteriophage therapy. d'Herelle first demonstrated the efficacy of phage therapy by curing 4 patients of shigellosis, and several subsequent studies confirmed the ability of phages to reduce Shigella based infection. Shigella spp continue to cause millions of illnesses and deaths each year and the use of phages ...

Since July 2002, bacteriologically confirmed shigellosis cases have increased, and multidrug-resistant Shigella dysenteriae serotype 1 strains have reemerged in patients hospitalized with diarrhea in Kolkata, India. The isolated strains of S. dysenteriae 1 showed resistance to chloramphenicol (80%), ampicillin (100%), tetracycline (100%), co-trimoxazole (100%), nalidixic acid (100%), norfloxaci...

Host resistance to Shigella infections can be decreased by non-specific physical stress. Fasting lowers the number of Shigella required for a parenteral LD(50) dose. While the LD(50) by the oral route is larger in fasted than in nonfasted animals, the fasted host's susceptibility to oral infection is increased as evidenced by the increased fecal Shigella carrier state, duration of intestinal in...

background and objective: gastroenteritis is one of the most important diseases in the world. this disease is more critical among children, people with immune deficiency and the sufferers from mal-nutrition. shigella spp. as the most important cause of dysentery, causes much mortality around the world. increasing antibiotic resistance is one of the major health problems. this research aimed to ...

Antimicrobial susceptibility of Shigella spp. and Escherichia coli, isolated from diarrhoeal patients in Lagos, was studied from March 1999 to February 2000. Four hundred fifty-nine isolates were identified as shigellae (62) and E. coli (397). Shigella flexneri, S. dysenteriae, S. boydii, and S. sonnei accounted, respectively, for 51.6%, 17.7%, 17.7%, and 13% of the total number of shigellae is...

background shigellosis as a global human health problem is more severe than other forms of gastroenteritis and causes over a million deaths in developing countries worldwide annually. fatality due to shigellosis is usually due to dehydration and two-third of fatalities are seen among children. the aim of current study was to describe fatal cases of shigellosis due to infection with shigella son...
