In vitroactivity of ticarcillin plus clavulanic acid (BRL 28500, ‘Timentin’) against ticarcillin-resistant Gram-negative rods

Current Medical Research and Opinion (1984)

B. Chattopadhyay Ivan C. Hall

SummaryA study was carried out to investigate the in vitro susceptibility of 211 clinical isolates of ticarcillin resistant (MICs >128 μg/ml) Gram-negative rods to a combination of ticarcillin plus clavulanic acid. The combination demonstrated superior activity; 90% of the Proteus spp. and 50% of E. coli and Klebsiella spp. isolates were inhibited at a concentration of 64 μg/ml. It was 2 to 8-times more active than ticarcillin alone against E. coli, Proteus and Klebsiella spp. in half to three-quarters of the strains under test. This enhanced activity was only marginal, however, against Enterobacter, Acinetobacter, Citrobacter, Serratia and Pseudomonas spp. Against 161 ticarcillin sensitive strains the combination did not have any potentiation effect.Key Words:: Ticarcillinclavulanic aciddrug combinationsmicrobial sensitivity tests

Faecal carriage rate of Aeromonas hydrophila.

Journal of Clinical Pathology (1983)

S. Millership S. R. Curnow B. Chattopadhyay

Over a four and a half month period, 1004 unselected routine faecal specimens from 815 patients were cultured for Aeromonas hydrophila. Forty-two specimens (4.2%) representing 38 patients were culture-positive. The study specimens also yielded Salmonella on 116 occasions, Shigella on seven, Campylobacter species on six and other bacterial pathogens on 17 occasions, respectively. Seven specimens had A hydrophila together with another bacterial pathogen. In only 19 of 38 patients (50%) was A hydrophila possibly associated with gastrointestinal symptoms. All the Aeromonas isolates were resistant to ampicillin but sensitive to gentamicin, piperacillin, mecillinam, chloramphenicol, ceftazidime and colistin.

Fatal neonatal septicaemia and meningitis due to Haemophilus influenzae acquired from the mother.

Postgraduate Medical Journal (1984)

B. Chattopadhyay

Summary A fatal case of neonatal Haemophilus influenzae type b, septicaemia and meningitis is described. Although the mother was asymptomatic, maternal genital tract culture yielded H. influenzae which was indistinguishable from the strain found in the infant. Despite the rarity of this organism as a cause of neonatal sepsis, increased awareness is essential so that this important offending pathogen is not missed.
