Phagocytosis and intracellular fate of Sporothrix schenckii.

Human polymorphonuclear leukocytes (PMNLs) phagocytized and killed yeast-phase cells of Sporothrix schenckii in vitro in the presence of 10% unheated serum. The combination of H2O2, KI, and human PMNL myeloperoxidase was lethal to yeast-phase S. schenckii. The results of this investigation suggest that PMNLs may play an important role in host resistance to infection with S. schenckii.

Infection with hair transplant surgery.

The problem of infection during hair transplant surgery in one dermatologist's office is described herein. Careful epidemiologic investigation identified the causative organism and its source, and the infection was effectively controlled by the use of "semi-sterile" technique. Infection may be more common than generally suspected and it should be considered as a possible cause of otherwise unexplained disappointing results as reflected by decreased numbers of viable hairs per graft.

Endocarditis associated with porcine valve xenografts.

Review of porcine valve xenografts in 68 patients over a 32-month period disclosed seven episodes of endocarditis in six patients, an attack rate of 10%. Four patients died as a result of the infections. The presence of Staphylococcus epidermidis in every case was most striking as was the preponderance of methicillin sodium resistance. The clustering of cases within a restricted time period, and the absence of subsequent cases, suggests the strong possibility of a nosocomial occurrence.

Antibiotic susceptibility of Staphylococcus aureus in Saigon, South Vietnam.

Methicillin resistant staphylococci are unevenly distributed throughout the world; the explanation for this is not known. During a survey of local hospitals for methicillin resistance, a number of strains from South Vietnam became available for study. Tests were performed in microtiter plates using various concentrations of several antibiol. With the larger number of organisms in the inoculum, 17% of strains required 12.5 mug/ml or more of methicillin for inhibition. This is in contrast to a very low percentage of methicillin resistant staphylococci from local sources encountered in our laboratory. An unexpected finding was the occurrence of considerable lincomycin resistance in staphylococci from South Vietnam.

Chloramphenicol-resistant Salmonella typhi in Saigon.

Chloramphenicol-resistant Salmonella typhi was detected in Saigon in September 1971. Subsequently, 163 strains of S typhi were isolated, 46 percent of which were resistant to choramphenicol by the agar-disk method. Sixty-two strains were studied by the broth-dilution method; 37 percent had minimal inhibitory concentrations for chloramphenicol greater than 250mug/ml, but all strains were susceptible to 0.4mug/ml of ampicillin and to a disk of a combination of trimethoprim and sulfamethoxazole (Bactrim). Persons infected with chloramphenicol-resistant strains of S typhi responded poorly to chloramphenicol alone, but ampicillin or the combination drug was effective.

Effects of cytochalasin B on the intrcellular bactericidal activity of human neutrophils.

Cytochalasin B (CB) is known to have some inhibitory effects on cytokinesis, single-cell movement, bacterial uptake by phagocytes, and many other processes. The effects of CB on intraleukocytic bactericidal activities in human leukocytes were studied, and the results were summarized as follows. (i) CB inhibited the early stage of the intracellular bactericidal activity of human leukocytes against Streptococcus pyogenes D58 (group A). The effect was rapidly eliminated by rinsing the CB solution. (ii) In the late stage of the intracellular bactericidal process, however, CB possessed no effect against S. pyogenes D58 (group A) and Staphylococcus aureus 209P. (iii) CB also inhibited the translocation of myeloperoxidase granules to the phagosomes of human neutrophils.

Lymphocyte-associated antigens in patients with alveolar cell carcinoma.

Antiserum produced in rabbits against a virus-like particle pellet recovered from human alveolar cell carcinoma (ACC) was used for the detection of lymphocyte-associated antigen in patients with ACC. The method used was direct immunofluorescence. The results demonstrate that lymphocytes from some patients with ACC possess antigen and the presence of lymphocyte fluorescence in patients with ACC suggests widespread or metastatic disease. The presence of antigen may be of both diagnostic and prognostic value.
