14. Penicillinase-producing gonococcal strains in Zambia. Observations on treatment failures.
Penicillinase-producing strains of Neisseria gonorrhoeae (PPNG) were detected in nine out of 27 (3.2%) treatment failures in 310 cases of acute gonococcal urethritis in men in Lusaka, Zambia. Minimum inhibitory concentrations of penicillin for 17.2% of 233 gonococcal isolates were less than or equal to 0.05 microgram/ml, for 38.2% between 0.125 and 0.25 micr

16. Lobar pneumonia in Northern Zambia: clinical study of 502 adult patients.
From July 1981 to January 1983 502 adults were treated for lobar or segmental pneumonia in a general hospital in Northern Zambia. Consolidation was present in either the right or the left lower lobe in 78.8%, the right middle lobe in 10.2% and either the right or the left upper lobe in 10.7%. Penicillin treatment failed to give an improvement in 10.7%, many

17. Wide needle aspiration cytology in the diagnosis of lymphadenopathy in Zambia.
AIMS--To study the value of wide needle (19 gauge) aspiration cytology in the diagnosis of lymph node disease in Zambia in the absence of a trained cytologist. METHODS--Patients (n = 304) referred for surgical biopsy of an enlarged peripheral lymph node were studied prospectively. Surgical biopsy was routinely preceded by 19 gauge needle aspiration of the sa

18. Genetic diversity of the envelope glycoprotein from human immunodeficiency virus type 1 isolates of African origin.
The genetic diversity of the envelope glycoprotein of human immunodeficiency virus type 1 (HIV-1) isolates was studied. HIV-1 isolates were obtained from eight countries in Africa: Djibouti, Gabon, Kenya, Senegal, Somalia, Uganda, Zaire, and Zambia. The DNA sequences encoding the complete HIV-1 envelope protein were PCR amplified and sequenced. Phylogenetic

19. Granuloma venereum
Granuloma venereum is endemic in Zambia but there are no previous reports of the disease from this geographical area. Six cases of granuloma venereum in African females were discovered on biopsy specimens. One unusual case with primary cervical involvement simulating carcinoma of the cervix is presented. This case illustrates the difficulties of diagnosis an

20. Child growth and duration of breast feeding in urban Zambia.
STUDY OBJECTIVE--The aim was to investigate the relationship between duration of breast feeding and growth of children. DESIGN--The study was a survey of randomly selected clusters of households. SETTING--The study was community based and took place in an urban township with a population of over 43,000 people in Lusaka, the capital city of Zambia. PARTICIPAN

21. Simplified Strategy for Detection of Recombinant Human Immunodeficiency Virus Type 1 Group M Isolates by gag/env Heteroduplex Mobility Assay
We developed a heteroduplex mobility assay in the gag gene (gag HMA) for the identification of group M subtypes A to H. The assay covers the region coding for amino acid 132 of p24 to amino acid 20 of p7 (according to human immunodeficiency virus type 1 [HIV-1] ELI, 460 bp). The gag HMA was compared with sequencing and phylogenetic analysis of an evaluation

22. Syphilis intervention in pregnancy: Zambian demonstration project.
Despite availability of simpler serologic tests for syphilis and near cure with penicillin, unacceptably high prevalence of infectious maternal syphilis exist in many developing countries, including Zambia. It is the foremost risk factor for mid-trimester abortions, stillbirths, prematurity and morbidity and mortality among infants born with congenital syphi

23. Oral ciprofloxacin versus ceftriaxone for the treatment of urethritis from resistant Neisseria gonorrhoeae in Zambia.
Neisseria gonorrhoeae strains resistant to treatment with penicillin, tetracycline, and/or spectinomycin are increasing in prevalence in many parts of the world. In Zambia, 52% of N. gonorrhoeae isolates produced beta-lactamase in 1986. Few oral regimens have proven effective for treatment of resistant N. gonorrhoeae. We conducted a prospective, double-blind

24. Molecular Epidemiology of Human Immunodeficiency Virus Type 1 Transmission in a Heterosexual Cohort of Discordant Couples in Zambia
Most human immunodeficiency virus type 1 (HIV-1) transmissions in sub-Saharan Africa are believed to occur between married adults who are discordant for their HIV-1 infection status; however, no studies to date have investigated the molecular epidemiology of such transmission events. Here we report the genetic characterization of HIV-1 strains from 149 trans
