It is possible to increase the sensibility of latex agglutination test in the diagnosis of purulent meningitis (
H. influenzae
, N. meningitidis, S. pneumoniae). The results with rate of the volume latex/CSF of 1/5, rotative
agitation
and lecture of agglutination after five minutes are better than volume 1/1, manual
agitation
and rapid lecture after two minutes.

An enzyme immunoassay (EIA) consists of a series of antigen-antibody reactions which result in the binding of an enzyme-labeled antibody to a solid phase. The performance time of an EIA determination is thus largely dependent upon the time required for the antigen-antibody reactions. In an attempt to develop a rapid EIA system, we investigated the time course of an EIA system for the measurement of Haemophilus influenzae type b polysaccharide. We found that, although the use of short incubations led to a decrease in sensitivity, an assay system utilizing 10-min incubation periods was still capable of detecting antigen at a concentration of 1 ng/ml. Important factors in the sensitivity of EIAs with short incubation times were the performance of the reaction at 37 degrees C and the incubation of the solid phase with constant
agitation
. Utilizing these techniques, we developed an EIA system for the measurement of
H. influenzae
type b polysaccharide which could be completed in less than 30 min. This system was sufficiently sensitive to detect
H. influenzae
polysaccharide in the cerebrospinal fluids of nine patients with proven
H. influenzae
meningitis. Thus, EIA systems utilizing short incubation times might be useful for the rapid detection of infectious antigens in body fluids.

Adherence to mucus may influence bacterial colonization of the respiratory tract. Clinical isolates of nontypable Haemophilus influenzae (NTHi) from the respiratory tract are often fimbriated. We wondered whether fimbriated strains have a different adherence from related nonfimbriated strains. A microtitre plate assay has been developed to study adherence of nontypable
H. influenzae
to mucus. Wells were coated by incubation either with sol phase of sterile mucoid secretions or with purified preparations of mucins. Two laboratory pairs of fimbriated (F+) and nonfimbriated (F-) nontypable
H. influenzae
, and six fresh clinical isolates of fimbriated nontypable
H. influenzae
each with nonfimbriated partners derived by serial passage on agar, were cultured to mid-log phase, washed, and then added to the wells. They were then incubated at 37 degrees C for 30 min before washing to remove unbound bacteria. Adherent bacteria were desorbed by
agitation
with 0.5% Tween 80 and a viable count performed. The two fimbriated laboratory strains (n = 12 and n = 17), and 5 of the 6 fimbriated clinical isolates were more adherent to sol phase than their respective nonfimbriated partners. Two nonfimbriated clinical isolates were more adherent to plastic than their fimbriated partners. A fimbriated laboratory strain was more adherent than its nonfimbriated partner both to a purified preparation of high molecular mass mucin and to the glycopeptide fraction of the same. We conclude that fimbriated strains of nontypable
H. influenzae
have increased adherence to sol phase of mucus and purified human respiratory tract mucin. The interactions of fimbriae with mucus are likely to be complex, and may involve both nonspecific and specific interactions.

The clinical and laboratory characteristics of bacterial meningitis in subjects over 59 years-old were evaluated to establish variables related to prognosis. All patients with clinical and laboratory findings of acute meningitis were included. Sixty-four episodes in 64 patients were registered. S. pneumoniae was responsible for 19 cases (27.5%); L. monocytogenes - 3; S. aureus - 1; S. bovis - 1; S. agalactie - 1 and Corynebacterium jeikeium 1. Gram negative bacilli caused seven cases; two cases were due to N. meningitidis and one to
H. influenzae
. In 50% of the cases no microorganisms were isolated. The main symptom was fever (67.8%). Headache and neck rigidity were absent in about one-half of the cases and the predominant symptoms were
psychomotor agitation
, stupor or coma. The presence of concomitant diseases, such as diabetes mellitus (26.6%) and pneumonia (17.2%), were common. The mortality was high (51.5%). This poor prognosis was related to L.monocytogenes (100%), Gram negatives rods (83%) andS.pneumoniae (58%). The univariate analysis showed that absence of headache (p=0.002), presence of coma (p=0.04), pneumonia (p=0.01) and immunocompromised status (p=0.01) were associated with risk of death. The type of the microorganisms isolated in the elderly patients with meningitis were often unusual ones. The clinical symptoms were minimal and in many cases, the only clinical presentation was change in mental status. Poor prognosis was observed in spite of intensive care. A high index of suspicion for meningitis while caring for elderly with changes in mental status must be maintained to avoid delays in initiating appropriate therapy.

Primary vaccination of infants with diphtheria-tetanus-acellular pertussis-hepatitis B recombinant (adsorbed)-inactivated poliomyelitis-adsorbed conjugated Haemophilus influenzae type b vaccine (DTPa-HBV-IPV/Hib; Infanrix hexa)-inactivated poliomyelitis-absorbed conjugated Haemophilus influenzae type b vaccine (DTPa-HBV-IPV/Hib) refers to Infanrix hexa trade mark.) provided high levels of seroprotection against diphtheria toxoid, tetanus toxoid, poliovirus 1, 2 and 3, pertussis antigens (pertussis toxoid, filamentous haemagglutinin and pertactin), hepatitis B virus surface antigen and
H. influenzae
polyribosyl-ribitol-phosphate (PRP) antigen. Most infants (97%) had anti-PRP levels >/=0.15 micro g/mL after a booster dose at 18 months. Primary vaccination with the DTPa-HBV-IPV/Hib vaccine produced a similar immune response to that with two different pentavalent plus monovalent vaccine combinations. Coadministration of DTPa-HBV-IPV/Hib vaccine and a heptavalent pneumonococcal conjugate vaccine resulted in a high level of seroprotection and was well tolerated. Primary or booster vaccination with DTPa- HBV-IPV/Hib vaccine was well tolerated. Commonly reported local adverse reactions included redness, pain and swelling. Systemic symptoms were usually mild to moderate, and included fussiness, fever,
restlessness
and sleepiness.
