Susceptibility of Haemophilus ducreyi to ampicillin and sulbactam in vitro.
Jones, B M, Hafiz, S, Duerden, B I
The MICs of ampicillin, ampicillin plus sulbactam in equal proportions, and a range of ampicillin concentrations with a constant 0.5 micrograms/ml concentration of sulbactam were determined for 66...
N. gonorrhoeae: pathogenicity of colonial type 5.
Hafiz, S, Jennings, R, McEntegart, M G, Jephcott, A E
This paper records the results of the intravenous inoculation of chick embryos with type 5 gonococci and establishes that these strains are pathogenic.
Odugbemi, T O, McEntegart, M G, Hafiz, S
Manganous chloride and Congo red incorporated into blotting paper discs have been used to differentiate gonococci from meningococci. The new technique is simple and reliable; the materials for the...

Anaerobic bacteria and herpes simplex virus in genital ulceration.
Masfari, A N, Kinghorn, G R, Hafiz, S, Barton, I G, Duerden, B I
Of 91 patients with genital ulceration, herpes simplex virus was isolated from 52 (57%) and Haemophilus ducreyi from 12 (13%); none had syphilis. The difference in incidence of other aerobes in...
Susceptibility of Haemophilus ducreyi to spectinomycin in vitro.
Hafiz, S, Jones, B M, Kinghorn, G R, Duerden, B I
Using an agar dilution technique with standardised inocula prepared by ultrasonication, the minimum inhibitory concentrations (MICs) of spectinomycin were determined for 66 strains of Haemophilus...
Prolonged survival of Neisseria gonorrhoeae in a new liquid medium.
Despite substantial improvements in solid culture media for gonococci and the development of liquid media for the short-term growth of the organism, we know of no study of the long-term survival of...
Effects of various divalent cations on the survival of Neisseria gonorrhoeae in liquid media.
Odugbemi, T, McEntegart, M, Hafiz, S
The effect of various concentrations of divalent cations on survival of gonococci in liquid medium was studied. The growth of Neisseria gonorrhoeae was inhibited by manganous chloride in...
Inhibition of Neisseria gonorrhoeae by normal human saliva.
Mellersh, A, Clark, A, Hafiz, S
Saliva was found to be a powerful and specific inhibitor of Neisseria gonorrhoeae. Although 28 other species of bacteria were tested, including Neisseria meningitidis, Neisseria pharyngis var flava,...
Induction of a cell wall variant of the gonococcus by human amylase.
Mellersh, A, Hafiz, S, McEntegart, M G, Geary, I
Human amylase has been shown to be an effective and powerful inhibitor of the gonococcus in vitro. Its action appears to be on the bacterial cell wall. When tested in osmotically stabilised liquid...
Hafiz, S, Kinghorn, G R, McEntegart, M G
The causative organism of chancroid, Haemophilus ducreyi, is generally considered to be very fastidious and its isolation, maintenance, and detailed study very demanding. In this study a modified...
Kinghorn, G R, Hafiz, S, McEntegart, M G
The pathogenic microbial flora of genital ulcers in 161 (80 men and 81 women) unselected patients was studied prospectively. In only one case was Treponema pallidum responsible whereas herpes simplex...
Actinomyces in the female genital tract. A preliminary report.
Actinomyces spp were isolated by culture of endocervical specimens from two groups of women attending the department of genitourinary medicine of the Royal Hallamshire Hospital, Sheffield. The first...
Sheffield medium for cultivation of Haemophilus ducreyi.
Hafiz, S, McEntegart, M G, Kinghorn, G R
Our interest in the role of Haemophilus ducreyi in genital ulceration led us to examine the various media commonly used for the cultivation of the organism. We describe an improved medium for the...
