Item AIDS and the gateway of the body.(1994-01-01) Bandyopadhyay, P; Bhowal, R N; Sikdar, S N; Roy, A K; Roy, J G; Bandyopadhyay, D; Pal, N C; Chatterjee, B DItem Antibacterial susceptibility of anaerobes by agar dilution method.(1991-05-01) Chakraborti, C K; Chatterjee, B DOf the 9 antibacterials, vancomycin alone at its break-point (optimum blood level) revealed highest (93.3%) efficacy on Gram-positive cocci. The remarkable activity of carbenicillin, chloramphenicol and vancomycin on Gram-positive cocci (95.4 to 96.9%), carbenicillin and chloramphenicol on Gram-positive bacilli (94.8% to 98.2%) and chloramphenicol on Gram-negative bacilli (95.4%) was noted by increasing their concentrations 1.5 to 2.5 times above their break-points. These (and even higher) concentration, however, showed relatively lower efficacy of metronidazole, rifampicin, penicillin, clindamycin and erythromycin on Gram-positive cocci (76 to 84.1%), rifampicin, tetracycline, erythromycin, clindamycin and vancomycin on Gram-positive bacilli (81 to 87.9%) and clindamycin, metronidazole, rifampicin and carbenicillin in Gram-negative bacilli (72.7 to 84%). By and large, rifampicin, chloramphenicol and carbenicillin are also quite effective (72.1 to 75.1%) at lower concentration.Item Bacteria in surface infections of neonates.(1995-04-01) Ghosh, S; Chatterjee, B D; Chakraborty, C K; Chakravarty, A; Khatua, S PA bacteriological work on surface infections was done among live births (study group I) and neonates admitted in hospital (study group II). Out of 134 cases of conjunctivitis in group I Gram-negative bacilli predominated (48.5%) with Escherichia coli accounting for 29 (14.9%) cases, Klebsiella species 15 (11.2%) cases, Citrobacter freundii 3 (2.2%) cases, Pseudomons aeruginosa 18 (13.4%) cases and Aeromonas hydrophila 3 (2.2%) amongst pure isolates (73.9%). Gonococcus was noted in 2 (1.5%) cases. In group II, 41.7% were Staphylococcus aureus in pure growth (75%), compared to only 9.0% in group I. Skin infections were caused by both Staphylococcus aureus and Staphylococcus epidermidis. Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa were the principal insolates from umbilical sepsis. Pseudomonas aeruginosa was isolated as pure growth from local site of noma neonatorum. Anaerobic cultures were negative in all except in 2 cases of umbilical sepsis with tetanus neonatorum revealing Clostridium tetani which however proved to be non-toxigenic. Blood cultures were positive in 4 out of 14 cases bearing 50% correlation with bacteria from surface infections. A source study established partial correlation with the cases of pseudomonas conjunctivitis. Phage typing of Staphylococcus aureus and biochemical typing failed to detect any definite marker of clinical entities, except that the skin infections were caused by group III phages predominantly (65.0%).Item Bacterial etiology of diarrhea in children with special reference to Campylobacter fetus jejuni.(1984-01-01) Khatua, S P; Pan, G D; Chatterjee, B DItem Citrate utilization of Vibrio parahaemolyticus.(1973-01-01) Chatterjee, B D; Neogy, K NItem Clinicobacteriological study of empyema thoracis in infants and children.(1990-07-01) Ghosh, S; Chakraborty, C K; Chatterjee, B DForty-one cases of empyema thoracis admitted in hospital during April, 1985 to August, 1987 were studied. Majority were males (65.9%) and were of less than 2 years of age (70.7%). Right side (60.9%) was predominantly involved. Abdominal distension (43.9%) was very characteristic, with other usual features like fever, cough and respiratory distress. A large majority of them were victims of malnutrition (73.2%) and anaemia (53.7%) with haemoglobin level ranging from 5-9 g/dl. Mortality was high (17.1%). Therapy with parenteral cloxacillin and gentamicin and continuous intercostal tube drainage accounted for loss of 15.8 bed days (average period of hospitalisation). Staph aureus was the principal aetiopathogen (68.3%). No anaerobe could be isolated. Strains of staphylococci were mostly resistant to penicillin and ampicillin but sensitive to gentamicin, cloxacillin and erythromycin.Item A clinicobacteriological study on leucorrhoea.(1998-02-26) Chaudhuri, M; Chatterjee, B D; Banerjee, MThe pathogens like Trichomonas vaginalis (4.5%), N gonorrhoeae (2.7%) and C albicans (6.7%) were exclusively present in leucorrhoea. The other potential agents with their respective percentages in normal women and cases of leucorrhoea were U urealyticum (21.2% and 50.2%), actinomyces (29.7% and 41.6%), Chlamydia trachomatis (17% and 48.8%), candida-like organisms (CLO) (1.2% and 9.5%) and non-group B streptococci (4.2% and 16.7%). The percentages of urethral syndrome (65.8%), vaginal irritation (63.4%), sore vulva (17%), cervicitis (13.4%), cervical erosion (11%) of the STD clinic were more than those of gynaecological cases. The latter group more often revealed infertility (15.8%) and pelvic inflammatory disease (13.6%). The exclusive isolation rate of N gonorrhoeae (7.3%) and prevalence of G vaginalis (19.5%) and Trichomonas vaginalis (8.5%) in the STD clinic were notable. The cases of gynaecological clinic more commonly showed C albicans (8%) and CLO (13.6%). Significant differences pertaining to U urealyticum (leucorrhoea and inapparent group p < 0.01; leucorrhoea and normal cases p < 0.01), M hominis (leucorrhoea and inapparent group p < 0.05; leucorrhoea and normal cases p < 0.01), Chlamydia trachomatis (leucorrhoea and normal cases p < 0.01) and also actinomyces (leucorrhoea and normal cases p < 0.01; inapparent and normal cases p < 0.05) were recorded. There was conspicuous association of U urealyticum, M hominis, G vaginalis, Chlamydia trachomatis, CLO and actinomyces with leucorrhoea. An almost exclusive presence of Staph aureus, Esch coli and Klebsiella in cases of leucorrhoea appeared meaningful.Item Common biotypes of non-cholera vibrios from cases of diarrhoea.(1971-08-01) Chatterjee, B D; Neogy, K NItem Current thoughts of non-sporing anaerobes in health and disease.(1990-08-01) Chatterjee, B D; Chakraborti, C KItem Diarrhoea associated with Campylobacter jejuni and its biotype coli in Calcutta.(1984-04-01) Chatterjee, B DItem Drug sensitivity of non-clostridial anaerobes.(1986-11-01) Chakraborti, C K; Chatterjee, B DItem Effect of antimicrobials on the microflora of chronic suppurative otitis media.(1985-11-01) Chatterjee, B D; Chakraborti, C K; Majumdar, P K; Mukherjee, A LItem Effect of beta-lactamase inhibitor on anaerobic isolates of Calcutta.(1988-05-01) Chakraborti, C K; Chatterjee, B DItem Enteroinvasive model of Vibrio parahaemolyticus.(1984-02-01) Chatterjee, B D; Mukherjee, A; Sanyal, S NItem An epidemiological study of systemic cryptococcosis in Calcutta area.(1967-06-01) Mallik, K C; Chatterjee, B D; Banerjee, P L; Dutta, MItem Etiology of acute childhood diarrhoea in Calcutta.(1989-07-01) Chatterjee, B D; Thawani, G; Sanyal, S NOf the 152 cases of acute diarrhoea, 124 (81.5%) revealed potential pathogens. Altogether 27 (21.2%) out of 127 strains of Escherichia coli, Klebsiella pneumoniae, Enterobacter, Proteus and Acinetobacter produced enterotoxin. Single pathogenic bacteria (40 cases 26.3%), parasite (6; 6%), rota virus (6; 6%), toxigenic bacteria (19; 12.5%) and mixed agents (37; 24.24.3%) were recorded in 108 cases (71.0%). Another 14 (9.2%) cases exclusively revealed moderate to heavy growth of suspected enteric pathogens like K. pneumoniae, Proteus, Enterobacter, Pseudomonas aeruginosa, anaerogenic E. coli and Citrobacter and 2 (1.3%) had high counts of T'. hominis. Of the known pathogens, the preponderance of A. hydrophila (24.4%), rota virus (15.7%) and Aeromonas hydrophila (14.0%) in 1-4 y, Vibrio cholerae (45.6%) and Trichuris trichiura (13.0%) in 4-14 y age group is highlighted. Other pathogenic bacteria were non-01 V. cholerae (3.2%), V. parahaemolyticus (2.6%), V. fluvialis (0.6), Plesiomonas shigelloides (3.9%), Salmonella (2.6%), Shigella (1.9%), EPEC (1.9%), EEC (5.2%) and Campylobacter jejuni (3.9%) and the parasites were Entamoeba histolytica (2.6%) and Giardia intestinalis (2.6). Comparative study of age matched controls with those of diarrhoea suggested the pathogenic role of E. histolytica and T. hominis.Item An experimental study of the course of infection in mice after intranasal insufflation with Cryptococcus neoformans.(1966-07-01) Mallik, K C; Banerjee, P L; Chatterjee, B D; Pramanick, MItem Flagellar diversity of Vibrio parahaemolyticus.(1974-10-01) Chatterjee, B DItem Gastric secretory study in protein calorie malnutrition (PCM) in adults and correlation with gastric mucosal structure, small bowel microflora and absorption.(1978-07-16) Guha Mazumdar, D N; Mitra, R C; Mitra, N; Sen, N N; Chatterjee, B DItem Ischaemic mouse thigh model for evaluation of pathogenicity of non-clostridial anaerobes.(1989-01-01) Chatterjee, B D; Chakraborti, C KA mouse thigh model has been devised in which the growing culture of non-clostridial anaerobe in the ischaemic tissue produces inflammatory swelling and death. The swelling of the right thigh served as an index of pathogenicity of the test strain in comparison to the negatively reacting left thigh which received injection of the control strain of Bifidobacterium infantis. Actinomyces naeslundii exceptionally caused death in all animals within 24 h. Mortality and thigh swelling were pronounced (greater than 75%) in case of Fusobacterium gonidiaformans and Propionibacterium acnes but less (less than 50%) in Acidaminococcus fermentans. High (less than 75%) rate of thigh swelling was also encountered in case of Bacteroides oralis, Bacteroides corrodens, Fusobacterium necrophorum, Fusobacterium prausnitzii, Fusobacterium plauti, Peptococcus prevotii, Streptococcus intermedius, Eubacterium lentum and Propionibacterium freudenreichii ss. shermanii.
