Isolation of Neisseria meningitidis strains with increase of penicillin minimal inhibitory concentrations.

We report the isolation and characterization of ten strains showing an increase in the minimal inhibitory concentrations to penicillin (MICs greater than 0.1 microgram/ml), and describe the epidemiological, clinical and microbiological features. The susceptibility of 3432 meningococcal strains isolated from patients in the recent epidemic wave (1978-86) in Spain, to several antimicrobial agents used in the treatment and chemoprophylaxis of meningococcal infection has been tested. Most were resistant to sulphadiazine but sensitive to other antibiotics. The possible existence of a new pattern of behaviour of meningococcal to penicillin is discussed.

Etiological agent and primary source of infection in 42 cases of focal intracranial suppuration.

The microbiological findings for 42 patients with focal intracranial suppuration were analyzed and correlated with the different sources of primary infection. Streptococcus spp. were identified in focal intracranial suppuration of all origins except postcraniotomy. Microaerophilic streptococci were important in cases secondary to respiratory tract infection and in those of unknown origin. Streptococcus faecalis, Proteus spp., and Bacteroides fragilis were the organisms most commonly found in polymicrobial otogenic abscesses. Clostridium sp. was the main microorganism implicated in postcraniotomy suppurations.

[Bacteriologic control of total parenteral nutrition formulations at the Bellvitge Hospital].

Septic complications often lead to halting nutritional parenteral therapy. In general, the source of infection lies in the mixture, the connection and/or point of catheter insertion. The objective of this study is to show the need for bacteriological control throughout the parenteral nutrition process in order to assess the efficacy of the methods used, discover the source of infection and establish an in-house quality control. Different methods for bacteriological control of parenteral nutrition mixtures are studied and are compared with the method used at our hospital which is based on routine culture sampling after the mixture is prepared and before it is perfused, on repeating bacteriological control cultures and on performing bacteriological assessments of the catheter. In order to achieve this goal, 28.501 nutritional parenteral samples from 1,782 patients were studied. Only 185 (0.65%) samples were originally positive, and only 59 of them (0.21%) remained positive following a verification culture. Of the 6 culture-verified septic cases, 5 corresponded to Enterobacter cloacae and 1 to Klebsiella pneumoniae.

[The bacteriological control of TPN mixtures at the Hospital de Bellvitge].

The complications of sepsis often make it necessary to suspend nutritional therapy. The origin of these is the nutritive mixture as well as the catheter connection and/or point where it has been inserted. The aim of this study is to show the need for bacteriological control of the whole process, in order to evaluate the effectiveness of the methods used, dilucidate the origin of the sepsis and establish an internal quality control. Study of different methods for bacteriological control of the nutritive mixtures, comparing them with the methods used in our Hospital, which is based on systematic culture of the mixtures, the collecting of samples after preparation and prior to perfusing the mixture through the patient, the performing of a further culture control and a bacteriological examination of the catheter. For this purpose, 28,501 nutritive mixtures were studied, corresponding to 1,782 patients. Of these, 185 samples were initially positive (0.65%) and only 59 samples showed positive cultures (0.21%). Of the 6 cases of sepsis discovered and confirmed by haemoculture, 5 corresponded to Enterobacter cloacae and 1 to Klebsiella pneumoniae.
