Haemophilus influenzae type b (HIb) is the most common cause of bacterial meningitis in children with a mortality rate ranging from 1.6% to 14%. Most patients have a 2-3 day history of symptoms prior to admission. A few have fulminating disease with rapid neurological deterioration. Review of 191 cases of HIb meningitis revealed a mortality rate of 2.1% but all who died had fulminating meningitis (FM). Four of six patients with FM died. FM patients had symptoms for less than 24 hours before rapid neurological deterioration with increased ICP, seizures, coma and/or respiratory arrest. Review of 10 FM cases revealed that on admission, 5 had hypotension, 3 had thrombocytopenia, and 8 had coma. Typical CSF changes were seen in only 7. All fatal cases died within 24 hours. Brain swelling and tonsillar herniation were found at autopsy. SDS-PAGE outer membrane protein subtyping did not show one "killer strain". Animal and autopsy data suggest that diminished CSF outflow and cerebral edema contribute to increased ICP. To improve survival of FM patients, initial treatment must (1) decrease ICP below levels impairing cerebral perfusion, (2) maintain adequate ventilation and blood pressure, and include (3) LP when stable, (4) antibiotics, and (5) close monitoring. Utilizing these principles, two FM patients survived without major sequelae.

Environmental contamination caused by heavy metals poses a major threat to the wildlife and human health for their toxicity and intrinsically persistent nature. Some specific food grade bacteria have properties that enable them to eliminate heavy metals from food and water. Lactococcus lactis subsp. lactis, newly isolated from pickles, is a cadmium (Cd) tolerant bacteria. Cd resistant properties of the lactis was evaluated under different Cd stresses. Cd accumulation in different cellular parts was determined by ICP-MS and cell morphology changes were measured by SEM-EDS and TEM-EDS. In addition, functional groups associated with Cd resistance were detected by infrared spectroscopic analysis. The results indicated that Cd mainly accumulated in the cell surface structures including cytoderm and cytomembrane. Functional groups such as OH and NH2 in the cell surface played essential roles in Cd biosorption. The elements of O, P, S, and N of polysaccharide, membrane protein and phosphatidate in the cell surface structures might be responsible for Cd biosorption for their strong electronegativity. This study indicated that ultrastructural analysis can be a supplemental method to study heavy metal resistance mechanism of microorganism and the newly isolated lactococcus lactis subsp. lactis has great potential to be applied to decontamination of heavy metals.
