BACTERIAL POLYSACCHARIDE IMMUNE GLOBULIN (BPIG) PROTECTS INFANT RATS WITH S. PNEUMONIAE (SP) PNEUMONIA FROM BACTEREMIA, MENINGITIS AND DEATH. • 1092

Anticapsular polysaccharide antibodies and nasopharyngeal colonization with Streptococcus pneumoniae in infant rats.

To evaluate the effect of passive immunization with anticapsular antibodies on nasopharyngeal carriage, two models of Streptococcus pneumoniae colonization were developed in infant rats. In a direct inoculation model, 3- to 4-day-old infant rats were intranasally inoculated with 2 x 10(5) cfu of S. pneumoniae type 3 or 6 x 10(3) cfu of S. pneumoniae type 23F. In an intralitter transmission mode...

Hyponatraemia associated with pneumonia or bacterial meningitis.

Serum sodium concentrations were measured in 93 children with pneumonia or bacterial meningitis on their admission to hospital. Hyponatraemia (sodium value 134 mmol/l or less) was present in 33 (45%) of the 73 children with pneumonia, and in 10 (50%) of the 20 children with bacterial meningitis. Increased secretion of antidiuretic hormone is common in children with pneumonia, as well as in chil...

Prevalence of Bacterial Isolates Related to the Meningitis and Bacteremia in two Hospitals During 2016-2017

Background and Objective: Hospitals niche as a source and repository for microbial infections are playing a significant role in the health of hospitalized patients. Bacteria are playing an essential role in human and animal blood infections and meningitis. The prevalence of bacterial agents and their susceptibility patterns are fundamental goals of current research. Materials and Methods: Samp...

Beta-lactamase effect on ampicillin treatment of Haemophilus influenzae B bacteremia and meningitis in infant rats.

Intraperitoneal injections of 250 mg of ampicillin per kg every 6 h for 30 h sterilized the blood and cerebrospinal fluid of infant rats infected with either a beta-lactamase-containing strain of Haemophilus influenzae type b or a strain lacking the enzyme. However, a single injection of 100 mg/kg sterilized the blood and cerebrospinal fluid of significantly fewer of those rats infected with th...
