ABSTRACT
A 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%).

Maternal and cord blood of 34 toxemic and 27 non-toxemic mothers and their infants were studied for lipids and glucose. All the lipid fractions in cord blood were significantly lower (P less than .001) than that of the mother in all groups due to relative impermeability of the placenta. AFD infants of toxemic mothers had significantly higher (P less than .001) value of FFA and triglyceride as compared with AFD infants of non-toxemic mothers. However SFD infants of toxemic mothers had higher FFA only when compared with that of non-toxemic mother. This is possibly due to sympathetic stimulation related to placental insufficiency with hypoxia and hypoglycemia that lead to mobilisation of adipose tissue into FFA and glycerol in fetus. Plasma phospholipid, cholesterol, HDLC, LDLC of infants of toxemic mothers were significantly lower (P less than .001), more so in SFD infants, possibly due to impaired liver function. 53% of infants of toxemic mothers also had hyperbilirubinemia. Cord blood glucose in toxemic group was significantly lower (P less than .05) than AFD infants of non-toxemic group.
