Infection 1979

Material from 334 consecutive autopsies on Orang Asli subjects performed in the University Hospital, Kuala Lumpur between May 1967 and June 1978 was examined for amyloidosis. Nine positive cases were found, all in patients above 40 years of age, giving an age-corrected incidence of about 9%. In 6 cases, amyloidosis was probably secondary to tuberculosis. The remaining 3 cases exhibited a pericollagenous distribution characteristic of primary amyloidosis. Involvement of the heart and lungs was prominent. However, there were considerable similarities in the distribution and staining properties of the amyloid in the 2 groups. Though both the heart and kidney were frequently affected, the kidney was the most common organ to give rise to clinical symptoms. Infection probably plays a major contributory role in amyloidosis in the Orang Asli.

Infection of the temperature-sensitive E. coli CRT 266 (dnaBts) with T3-phages at the temperature of 30 degrees C and 35 degrees C, respectively, induced T3-specific RNA synthesis with a maximum rate at 7 min (30 degrees C) and 4.5 min (35 degrees C) after infection. At temperatures above 40 degrees C no T3-induced RNA synthesis could be observed. Infection of E. coli CR 34--45 (dnaB+) with T3 phages at 30 degrees C, 35 degrees C and at temperatures above 40 degrees C, however, produced T3-specific RNA synthesis. The maximum of T3-induced RNA synthesis could be observed between 7 min and 3 min depending on the temperature during infection. The inability to form T3-specific RNA after infection of E. coli CRT 266 at nonpermissive temperatures may be a cause for the absence of the formation of T3 phages and lysis of the host cells.

A fecal filtrate of human origin containing the Norwalk agent of epidemic viral gastroenteritis was administered by stomach tube to chimpanzees in an attempt to induce diarrheal disease. Significant postchallenge serum antibody rises against Norwalk viral antigens were demonstrated in all animals using the techniques of immune electron microscopy and radioimmunoassay. In addition, viral antigens were detected in feces from five of nine animals using radioimmunoassay. Clinical illness characterized by diarrhea and/or vomiting did not occur. Infection was transmitted subsequently by feeding four additional chimpanzees a fecal filtrate prepared from one of the previously infected animals. Development of an antibody response in four animals and detection of viral antigen in two animals that received this passage filtrate indicated that viral replication had occurred in the absence of clinical illness. The availability of the chimpanzee as an experimental animal host susceptible to infection with the Norwalk agent should facilitate the study of epidemic viral gastroenteritis.

The provision of adequate nutrition to hospitalized patients with exceptional caloric requirements has been a problem until the recent advent of intravenous hyperalimentation. With total parenteral nutrition (TPN), the nutritional needs of any patient can be met by infusion. TPN solution is hypertonic, and administration requires central venous cannulation. The subclavian vein is usually chosen as route of access to the superior vena cava. Strict aseptic technique must be used in inserting the catheter and making up and administering the solution. TPN is not without risk. Infection is always a possibility, as are metabolic alterations, such as electrolyte imbalance, fluid overload, osmotic dehydration, and essential fatty acid deficiency.

A 10-year analysis of 113 cases of staphylococcal endocarditis seen in two Washington, D.C., hospitals is presented. 96% of the cases occurred in parenteral drug addicts, but 4% complicated septicemia from known foci of infection. Coagulase positive staphylococcus was responsible for 97% of the infection, and the rest were caused by coagulase negative staphyloccus. Except in four patients with previously known cardiac murmurs, infection occurred on normal valves in these patients. Infection was isolated to the tricuspid valve in 71%, to the mitral valve in 6% and to the aortic valve in 3.5% of our cases; and more than one cardiac valve was affected in the remaining patients. All patients were treated with antibiotics based on bacterial sensitivity testing. The mortality from isolated tricuspid endocarditis was 5%, from isolated mitral endocarditis 33%, and from isolated aortic valve endocarditis 100%. The overall mortality was 18%. The better prognosis documented for acute tricuspid endocarditis is related to the much less severe haemodynamic consequences of acute tricuspid regurgitation, and the probably milder consequences of septic pulmonary embolism compared with coronary or cerebral embolism.

Microsporidian infection is reported in Liza ramada (Risso), Mugilidae, from Bardawil Lagoon, Mediterranean coast of Sinai, in the fibroblasts of the metacercarial capsule of Heterophyes heterophyes (Siebold). Infection of the metacercarial cyst resulted in an hypertrophy of the cyst wall and degeneration and eventual death of the encapsulated metacercaria.

The in vitro activity of gentamicin, tobramycin, sisomicin, netilmicin, amikacin, kanamycin and streptomycin was tested simultaneously by the agar dilution method against 584 clinical isolates of gram-negative bacilli that were resistant to gentamicin and/or tobramycin. About half of the gentamicin-resistant Pseudomonas were susceptible to tobramycin but cross-resistance was virtually complete between gentamicin and tobramycin for Enterobacteriaceae. Sisomicin was much more active than gentamicin against Klebsiella, Escherichia and Citrobacter species. Only 18.9%, 27.4% and 27.9% of Klebsiella, Enterobacter and Serratia respectively were resistant to netilmicin. Amikacin was the most effective aminoglycoside with an overall resistance of 15.6%. Kanamycin was effective against 40% of Proteus and Providencia species. Surprisingly, more than half of Klebsiella and Enterobacter species and 85.3% of Serratia species were susceptible to streptomycin.

Infection with the Friend murine leukemia virus complex (F-MuLV) suppressed humoral antibody synthesis in vivo and lymphocyte mitogenesis in vitro. Both these effects of F-MuLV were under host genetic control. In vitro suppression of lymphocyte mitogenesis was regulated by a single autosomal gene called Fv-3 that is dominant for susceptibility. Genetic analyses, with the use of the susceptible DBA/2 and resistant B10.D2/n parents, their F1, intercross, and backcross progeny, indicated that a single autosomal gene dominant for susceptibility regulated the in vivo susceptibility to immunosuppression by F-MuLV. Individual [(DBA/2xB10.D2)F1xB10.D2] mice were typed both for susceptibility to F-MuLV-induced suppression of lymphocyte mitogenesis in vitro (an Fv-3 function) and susceptibility to immunosuppression by F-MuLV in vivo. Such an analysis indicated that the same mice that were susceptible or resistant to immunosuppression in vivo were susceptible or resistant to suppression of lymphocyte mitogenesis in vitro. Spearman's rank analysis of the data also indicated that the in vivo and in vitro immunosuppressive effects of F-MuLV were correlated with and not independent of each other. Thus Fv-3, which regulates the effect of F-MuLV on lymphocytes in vitro, also appears to regulate the effect of F-MuLV on antibody-forming cells in vivo.
