22) Although WHO recommends ceftriaxone, pivmecillinam and azithromycin for shigellosis due to the increase in fluoroquinolone resistant shigellae, the species was found to be resistant to one of the third generation cephalosporins and azithromycin.
Its production in Shigellae is of concern especially in children, in whom treatment options are already limited.
However, shigellae resistant to these drugs have emerged in the United States and abroad (7-17).
Increasing rates of shigellosis among adult males, particularly men who have sex with men (MSM), have been documented in the United States, Canada, and Europe (1-4), and MSM appear to be at greater risk for infection with shigellae that are not susceptible to ciprofloxacin or azithromycin (5-8).
Briefly, the procedure was this: 5-6 colonies of Shigellae were picked from overnight growth and suspended in 100 [micro]L of sterile molecular-grade water and was boiled at 100[degrees]C for 10 minutes, following which flash-cooling was done on ice for 5 minutes.
dysenteriae), Shigella flexneri, Shigella sonnei, and Shigella boydii are the four species that comprise the Shigellae genus and are divided into over 45 serotypes depending on the structure of the O antigen component of their outer membrane lipopolysaccharide (1), (3).
As in all developing countries, the choice of limited number of effective antimicrobials for empirical treatment of suspected infections caused by rapid emergence of multi-drug resistant shigellae has been a problem to clinicians in these islands.
boydii 20 was more multidrug resistant than other shigellae.
Molecular study of the 10 isolates revealed that Shigella boydii 20 was more multidrug resistant than other shigellae, she said.
As demonstrated in this outbreak, and a larger scale outbreak in 1973 in Bucks County, Pennsylvania, despite strong epidemiologic evidence and the isolation of Shigella from affected individuals, shigellae are rarely isolated from implicated water (5).
