Despite the high prevalence of pharyngeal gonorrhea and of meningococcal carriage among homosexual men, Neisseria gonorrhoeae and Neisseria meningitidis are rarely co-isolated from the throat. Forty-seven meningococcal isolates from the pharynx of homosexual men were examined, by a lawn-spotting method, for their ability to inhibit N. gonorrhoeae in vitro. Eight (17%) of the meningococcal isolates were inhibitory when tested against gonococci from the same patient, while 31 (66%) were inhibitory when tested against N. gonorrhoeae strain 650 (T1). The colonial type T1 of a given strain was, in all cases tested, more sensitive to the inhibitory activities than the corresponding T4 type. Since the meningococci co-isolated from the throat with gonococci were at least as inhibitory in vitro as those isolated without gonococci, the natural resistance to gonococcal pharyngitis cannot be explained on the basis of the inhibitory activities produced by the meningococci in vitro. The inhibitory strains of N. meningitidis were identified in decreasing importance as: nonserogroupable, W135, C, B, 29E, and X. The addition of trypsin to the solid medium removed the inhibition produced by the meningococci, an observation suggesting the involvement of protein inhibitors.

Fibrinogen binding activities in culture supernates of group A streptococci were detected by dot blot assay using horseradish peroxidase conjugated human fibrinogen. Various intensities in colored dots were seen in 63 of 70 strains isolated from pharyngitis patients in 1992. Strong binding activities in all of 16 strains were partially sensitive to trypsin digestion. The binding activities in the concentrated culture supernate of M-type 4 strain SS91 were analysed by SDS-PAGE and Western blotting. Intense colored bands and faint ones were seen in the position corresponding to 89K, 66K, 59K, 49K, 42KDa and 77K, 53K, 51K, 44KDa, respectively. Only one band at 42KDa remained after trypsin digestion.

Under an influenza surveillance initiated in Pune, India, 2 or 3 dispensaries and small hospitals where patients with acute respiratory disease (ARD) sought medical assistance were chosen for regular weekly visits to collect a sufficient number of specimens. A case of ARD included individuals with the following conditions: common cold, pharyngitis, laryngitis, tracheitis, bronchitis, bronchiolitis, pneumonia, or bronchopneumonia. During the period of surveillance of 1978-90, more than 10,000 cases of ARD among various age groups were investigated. The majority of cases were in children and infants. Most of the patients were seen during investigations of 16 outbreaks of influenza. Generally, the cases presented with 2 or 3 symptoms of respiratory disease and 1 or 2 systemic manifestations. Throat and nasal swabs were collected from ARD cases during the acute phase of their illness (1-4 days). Throat/nasal swabs were taken from over 10,000 ARD cases. About 80% of these specimens were cultivated for influenza virus in embryonated chicken eggs (9-11 days' old) and about 39% in Madin-Darby canine kidney cell culture (MDCK) with crystalline trypsin. Several variants of influenza virus types A and B were isolated during the 16 outbreaks including these variant strains: A/USSR/77 (H1N1) in 1978; A/Singapore/6/86 (H1N1) in 1986; and B/Yamagata/16/88-like in 1990. A total of 290 influenza virus isolates comprising several variants of influenza type A (H3N2) and A (H1N1) and type B were isolated. The variant strains of influenza type A (H1N1), type A (H3N2), and type B circulated regularly either every year or in alternate years. 181 of 290 of the influenza isolates were from children aged 10 years. Analysis of the isolates showed that 174 were from the rainy months of July, August, and September, and the maximum number of 93 occurred in July. Of the 16 outbreaks of influenza, 10 occurred in the rainy season, 3 in the hot season, 1 in the cool season, and 2 in February and March.
