    The viability of three recently isolated local strains of Bact. typhosus has been studied on 20 specimens of local hawker’s syrup used for sweetening ice balls and ice water. Precise survival times cannot be stated and only relatively wide limits can be estimated differing possibly in every individual case. Survival is influenced by the following factors : 1. The character of the containing material 2. The presence of other bacteria 3. Temperature 4. The presence of bactericidal agents or substances Significant diminution of the number of bacteria in 2 to 5 days after inoculation to sugar solutions is an important observation although survival up to two weeks has been noticed in repeated experiments. The results of experiments conducted in market syrup samples and on control experiments with laboratory sugar solutions indicate that the survival of the organisms tends to be more prolonged in dilute solutions than in concentrated

    Perforated appendix is a serious surgical condition that carries a high morbidity. Antibiotic treatment is often started before the availability of bacteriological reports. The choice of antibiotics would depend on the bacteriology associated with perforated appendix. In a retrospective survey of the bacteriology of peritoneal pus obtained from cases of perforated appendix at the General Hospital, Kuala Lumpur, E. coli was found to be the most commonly encountered organism. This was followed in order of decreasing frequency by streptococci, Bacteroides species, Klebsiella-Enterobacter group and Pseudomonas aeruginosa. From the results of the antibiotic sensitivities an antibiotic regimen comprising of a combination of gentamicin, metronidazole and penicillin is recommended as appropriate chemotherapy in perforated appendix.

    Nonfermentative Gram-negative bacilli were commonly isolated from clinical material in a Malaysian hospital over a two year period of study. Pseudomonas aeruginosa, Acinetobacter sp and other Pseudomonas were the most common organisms seen. Although these bacteria occurred regularly in clinical specimens their pathogenetic role could be established in only a small proportion of cases. Most 01 these organism were either contaminants or
    commensals 01 the normal bacterial flora. It is important to interpret the isolation of a nonfermentative Gram-negative bacillus with caution, and in the light of clinical findings. Failure to do so may result in the unnecessary use of antibiotics.

    The eye harbours bacteria from the time of birth throughout life. Owing to its antibacterial properties, the normal conjunctival flora plays a significant role in the defence against superficial ocular infections. In view of its protective action as well as its probable role in causing ocular disease under certain circumstances, the study of the normal flora and its pattern of antibiotic susceptibility could provide useful information in the prevention and treatment of post-surgical infections. While several such surveys have been reported from various parts of the world, no data is available for the Malaysian population. This survey seeks to establish the pattern of bacterial flora in healthy conjunctivae of Malaysians. In addition, the bacterial flora of a nondiabetic population was compared to that of a diabetic population to see if there were any differences.

    A retrospective study of 84 cases of neonatal septicaemia admitted into a neonatal unit in a rural area of Malaysia for 1 year between 1st September 1985 to 31st August 1986 was carried out to determine the spectrum of micro-organisms and predisposing factors in relation to early and late onset septicaemia. The incidence of neonatal septicaemia was 2.13 per 1,000 live-births per year and the case fatality was 41.7% with higher case fatality in those who were premature, those who presented as early onset and those who had gram negative septicaemia. The mean age of onset of septicaemia was 7.8 days (range from 2 hours to 27 days). Forty four (52%) neonates had early onset septicaemia with mean age of onset at 2.7 days; forty (48%) neonates had late onset septicaemia presenting at 13.6 days of life. Gram negative organisms such as Klebsiella, Pseudomonas, sp., E. coli and Streptococcus, especially group B Streptococcus were the major organisms in the early onset septicaemia. Staphylococcus aureus and Staphylococcus epidermidis were the major organisms responsible for the late onset septicaemia. Obstetrical factors played an important role in early onset septicaemia. Prematurity was the most common predisposing factor. Invasive diagnostic and therapeutic procedures including surgery highlighted once again the importance of these procedures in predisposing the newborn to infection.

    A survey was conducted in 4 paediatric wards in Malaysia to determine the distribution of various species of cockroaches and to examine their gut contents for bacteria. Cockroaches were trapped from food dispensing areas (kitchens), store rooms, cupboards and open wards. 104 cockroaches were caught, consisting of Periplaneta americana (67.3%), Blattella germanica (26%), P. brunnea (4.8%), and Supella longipalpa (1.9%). Bacteria were isolated from all cockroaches except 3 P. americana. Many bacterial species were identified, including the pathogenic and potentially pathogenic species Shigella boydii, S. dysenteriae, Salmonella typhimurium, Klebseilla oxytoca, K. ozaena and Serratia marcescens.

    Antibiotic resistance in Gram-negative bacteria, particularly Salmonella and Shigella, requires surveillance worldwide. This study describes results of surveys in Hong Kong, Bangkok and Kuala Lumpur. All strains were isolated in hospitals which have large community catchment areas in addition to specialised hospital units. The prevalence of resistant strains was high in all areas. Gram-negative bacteria such as Enterobacter associated with hospital infections were resistant to penicillins and cephalosporins, with gentamicin resistance ranging from about 20% in Kuala Lumpur and Hong Kong, to 35% in Bangkok. Ninety-seven percent of Shigella isolated in Thailand were resistant to ampicillin. About 10% of Salmonella were resistant to chloramphenicol in all three centres.

    The in vitro activity of teicoplanin and A16686, two new glycopeptide antibiotics was determined against 196 isolates of anaerobic bacteria. The activity of teicoplanin and A16686, in comparison with that of vancomycin, clindamycin, erythromycin and fusidic acid was 2 to 16 times higher against the gram positive anaerobes, namely, Propionibacterium acnes, Clostridium perfringens, Clostridium difficile, Clostridium species, Peptococcus species and Peptostreptococcus species. However, Bacteroides fragilis was resistant to teicoplanin and A16686 while Bacteroides melaninogenicus and Bacteroides bivius were found to be sensitive.

    Twenty-nine adult patients with culture-positive thoracic empyema were seen at the University Hospital Kuala Lumpur from 1984 to 1988. Cough, fever, chest pain, dyspnoea and weight loss were the common presenting symptoms. The empyema in 16 patients was associated with primary bronchopulmonary infections, nine occurred following thoracentesis of culture-sterile pleural effusions, two occurred as post-thoracic surgery complications, one following a subdiaphragmatic abscess and one as a result of a stab wound. The most common culture isolates were Streptococcus milleri, Pseudomonas aeruginosa and Klebsiella pneumoniae. Closed tube thoracostomy, the most common form of drainage procedure employed, was able to effect a cure or control of the empyema in 11 out of 19 patients in whom it was used.

    31 cases of intracranial abscess seen over a period of 10 years showed a peak incidence in the second and third decades of life with a male preponderance. Tetralogy of Fallot and other congenital cyanotic heart diseases were the predominant associated factors (32%). The commonest site of infection was the frontal lobe. Gram-stained smears of pus proved to be extremely useful. The majority of the organisms (82%) were either microaerophilic or anaerobic bacteria with Streptococcus milleri being the most frequent isolate. With the exception of Corynebacterium species, all isolates were susceptible to penicillin or chloramphenicol, most being susceptible to both.

    The anti-phospholipid antibody (aPL) in 26 heat-inactivated normal human sera (NHS) was tested for IgG subclass in ELISA. The specific antibody in NHS included all four IgG antibody subclasses, as well as IgA. The incidence of IgG subclasses ranged from 50% (13/26) for IgG1 to 92% (24/26) for IgG2. Specific IgA anti-phospholipid antibody (aPL) was detected by ELISA in 38% (28/73) of normal human saliva. The salivary IgA aPL bound preferentially to anionic phospholipids including cardiolipin, phosphatidylserine and phosphatidic acid but not to phosphatidylcholine or sphingomyelin. Unlike aPL in normal human sera, aPL in saliva was predominantly not associated with the previously described heat-labile inhibitor of aPL. This may indicate a role of salivary IgA aPL in local immunity by binding to cross-reactive bacterial cell surface components including phospholipids.

    One hundred children with peritonitis resulting from a perforated appendix were treated with ceftazidime or netilmicin. Metronidazole was added to both groups to treat the anaerobic organisms commonly associated with the infecting aerobic organisms in peritonitis. Escherichia coli was the most common aerobe found in peritoneal pus. Wound infection occurred in nine patients of the netilmicin group and in none treated with ceftazidime (P less than 0.01). No bacterial resistance was evident in the ceftazidime group, but gram-positive streptococci found in eight patients were resistant to netilmicin. Thus it is recommended that an antibiotic of the penicillin group be added if netilmicin is used to treat peritonitis. The results indicate that ceftazidime was more effective than netilmicin in the treatment of children with peritonitis resulting from a perforated appendix.
