| the fortuitous diagnosis of cholera in a two-year-old girl. | we are reporting the fortuitous diagnosis of a case of cholera and the unusual failure of the commercial bacteriologic media that led to the unexpected isolation of vibrio cholerae. the case demonstrates the need for communication between the medical staff and laboratory personnel when an uncommon disease, such as cholera, is suspected. this case also alerts the clinician to the possibility of multiple enteric pathogens coinfecting a traveller. | 1992 | 1315232 |
| comparative in vitro activity of enoxacin and other fluoroquinolones against multi-resistant strains of salmonella typhi. | the in vitro activities of enoxacin, lomefloxacin, norfloxacin, ofloxacin, and pefloxacin against 274 strains of salmonella typhi isolated from suspected typhoid fever patients (137 multi-resistant strains and 137 strains sensitive to chloramphenicol, ampicillin and/or co-trimoxazole) were determined using disk diffusion and agar dilution techniques. in vitro, enoxacin was active against all tested strains with a mic90 and inhibition zone size against multi-resistant strains of 0.12 mg/l and 34 ... | 1992 | 1316257 |
| the quinolones. an overview of their pharmacology. | the fluoroquinolones represent a relatively new class of antibiotics with outstanding therapeutic potential, attributable to their broad spectrum of antimicrobial activity and favourable tissue distribution. they are highly active against most gram-negative pathogens, as well as staphylococcus aureus and coagulase-negative staphylococci. in addition, the fluoroquinolones have useful pharmacokinetic properties: they are orally active, and their lipophilicity and low degree of plasma protein bindi ... | 1992 | 1319865 |
| inducible overproduction of the aspergillus nidulans pentafunctional arom protein and the type-i and -ii 3-dehydroquinases from salmonella typhi and mycobacterium tuberculosis. | the aroq gene of mycobacterium tuberculosis, encoding a type-ii 3-dehydroquinase, and the arod gene of salmonella typhi, encoding a type-i 3-dehydroquinase, have been highly overexpressed in escherichia coli using the powerful trc promoter contained within the expression vector pkk233-2. the m. tuberculosis type-ii 3-dehydroquinase has been purified in bulk from overproducing strains of e. coli to greater than 95% homogeneity. the protein is extremely heat-stable, is active as a homododecamer an ... | 1992 | 1329726 |
| active protection of mice against salmonella typhi by immunization with strain-specific porins. | nih mice were immunized with between 2.5 and 30 micrograms of two highly purified porins, 34 kda and 36 kda, isolated from the virulent strain salmonella typhi 9,12, vi:d. of mice immunized with 10 micrograms of porins, 90% were protected against a challenge with up to 500 ld50 (50% lethal doses) of s. typhi 9,12,vi:d and only 30% protection was observed in mice immunized with the same dose of porins but challenged with the heterologous strain salmonella typhimurium. these results demonstrate th ... | 1992 | 1333686 |

| [a study of some pathogenic factors of salmonella typhi]. | 30 strains isolated from clinical cases and a laboratory induced r-mutant or s typhi were studied. the synthesis of colicin v, siderophores, hydroxamate and phenolate (aerobactin and enterochelin) were investigated using biological assays. all strains were positive for enterochelin but only strains 6586 and 4448 were positive for aerobactin. an 80 kd receptor for enterochelin was found in the outer membrane of strains. only strains 4448, 635 and 4693 produced colicin v. plasmid related antibioti ... | 1992 | 1340565 |
| present phage types and antibiotic susceptibility of salmonellae. | a total of 168 strains of salmonella were isolated in the command pathology laboratory (wc) delhi cantt during the year 1990. out of this, 143 were salmonella typhi, 17 salmonella paratyphi a, 7 salmonella typhimurium and 1 salmonella manhattan. the commonest phage type and biotype of salmonella typhi was type e1 and type 1 respectively. the dominant biotype of salmonella paratyphi a was type i. there was a very high degree of multidrug resistance of most of the strains. but all the strains were ... | 1992 | 1344225 |
