13. Prevalência de anticorpos anticardiolipina na trombose periférica
The anticardiolipin antibodies have been associated with thrombosis, repetitive miscarriages and thrombocytopenia. The prevalence of these antibodies in peripheral thrombotic states has been studied little and sometimes the available data has great discrepancies. The importance of this situation is emphasised once that the therapeutic procedures, in the shor

14. In vitro activities of ampicillin-sulbactam and cefoperazone-sulbactam against oxacillin-susceptible and oxacillin-resistant staphylococci.
Ampicillin-sulbactam and cefoperazone-sulbactam were tested against staphylococci that were collected from 40 different medical centers throughout the United States. Oxacillin-resistant strains were resistant to both drug combinations, but oxacillin-susceptible strains were uniformly susceptible. The latter included strains with borderline susceptibility to

15. Surveillance for Antiviral-Agent-Resistant Herpes Simplex Virus in the General Population with Recurrent Herpes Labialis
In a general population survey in the United States, the prevalence of antiviral-agent-resistant herpes simplex virus was very low among more than 1,000 isolates from individuals with an episode of recurrent herpes labialis not treated with topical antiviral agents. Two isolates had borderline resistance to acyclovir (0.2%), and all were susceptible to penci

16. Association of Borderline Oxacillin-Susceptible Strains of Staphylococcus aureus with Surgical Wound Infections
Staphylococcus aureus isolates which produce type A staphylococcal β-lactamase have been associated with wound infections complicating the use of cefazolin prophylaxis in surgery. To further evaluate this finding, 215 wound isolates from 14 cities in the United States were characterized by antimicrobial susceptibility and β-lactamase type and correlated wi

17. New mechanism for methicillin resistance in Staphylococcus aureus: clinical isolates that lack the PBP 2a gene and contain normal penicillin-binding proteins with modified penicillin-binding capacity.
Seventeen clinical isolates of Staphylococcus aureus (from the United States and Europe) selected for low (borderline)-level methicillin resistance (MIC of methicillin, 2 to 4 micrograms/ml; MIC of oxacillin, 0.5 to 8 micrograms/ml) were examined for their mechanisms of resistance. Five strains were typical of heterogeneous S. aureus: they gave positive reac

18. Demographic and dietary profiles of high and low fat consumers in Australia.
STUDY OBJECTIVE--To determine the socio-demographic, attitudinal, and dietary correlates of high and low fat consumption in the community. DESIGN--The study was undertaken using a postal survey format. A questionnaire was sent for self completion to a randomised sample of the adult population of two Australian states. PARTICIPANTS--Adult participants were se

19. Antimicrobial Susceptibility Testing of Bacillus anthracis: Comparison of Results Obtained by Using the National Committee for Clinical Laboratory Standards Broth Microdilution Reference and Etest Agar Gradient Diffusion Methods
We determined the patterns of antimicrobial susceptibility of 65 isolates of Bacillus anthracis (50 historical and 15 recent U.S. clinical isolates) to nine antimicrobial agents using the National Committee for Clinical Laboratory Standards (NCCLS) broth microdilution reference method. The results for the 50 historical B. anthracis isolates obtained by the b

20. Detection of Anti-West Nile Virus Immunoglobulin M in Chicken Serum by an Enzyme-Linked Immunosorbent Assay
The emergence of West Nile (WN) virus in New York and the surrounding area in 1999 prompted an increase in surveillance measures throughout the United States, including the screening of sentinel chicken flocks for antibodies. An enzyme-linked immunosorbent assay (ELISA) for the detection of chicken immunoglobulin M (IgM) to WN virus was developed, standardiz

21. Identification of Mycobacterium leprae antigens from a cosmid library: characterization of a 15-kilodalton antigen that is recognized by both the humoral and cellular immune systems in leprosy patients.
Screening of the Mycobacterium leprae cosmid library with pooled sera from lepromatous leprosy (LL) patients by a colony immunoblot technique resulted in the identification of about 100 colonies that produced immunologically reactive proteins. Twenty-four of these clones were purified, analyzed, and found to comprise two groups according to the reactivity of
