    Author: Demina AA, Il'ina TV.
    Journal: Zh Mikrobiol Epidemiol Immunobiol; 1985 Nov; (11):3-6. PubMed ID: 3937391.
    Abstract:
    The results of the evaluation of the diagnostic latex preparations Bactigen, manufactured by Wampole Laboratories (USA) and intended for the detection of meningococcal antigens, serogropus A, B, C, Y, pneumococcal polyantigens and type b Haemophilus influenzae antigens in the spinal fluid and blood of patients with meningococcal infection and purulent bacterial meningitides, are presented. The pathological material was studied by traditional methods and by the latex agglutination (LAG) test. 522 LAG tests were made, including 414 tests for meningococcal infection, 60 tests for pneumococcal infection and 48 tests for type b H. influenzae. The results of this study revealed that the latex preparations were highly specific with respect to type b H. influenzae antigens and meningococcal antigens (false positive reactions constituted 0.96%). The simplicity of the test and the rapid techniques making it possible to obtain results within 30-40 minutes indicate good prospects of using the LAG test in laboratory practice.
