METHICILLIN-INDUCED LYSOZYME-SENSITIVE FORMS OF STAPHYLOCOCCI. (1/3)
Aldrich, K. M. (The University of Kansas, Lawrence), and C. P. Sword. Methicillin-induced lysozyme-sensitive forms of staphylococci. J. Bacteriol. 87:690-695. 1964.-Staphylococcus aureus and S. epidermidis grown in the presence of sublethal amounts of methicillin were converted to enlarged spheres within 2 to 4 hr, as shown by phase microscopy, Gram stain, and electron microscopy. Addition of lysozyme to cells incubated in the presence of methicillin, and to methicillin-induced spheres suspended in hypotonic saline, caused lysis of methicillin-treated cells but not of untreated cells.

Radiation was used extensively for the treatment of all types of infections before the advent of antibiotics. Although this mode of therapy is now in disrepute, radiation therapists of that era were firm believers in the ability of radiation to cure infections. A review of the literature suggests, but certainly does not prove, that low-dose local radiation, in the range of 75 to 300 roentgens, is an effective treatment modality for a wide variety of infections. Two then-prevailing rationales held that the effect was due either to radiation damage to the immune cells, causing stimulation of the immune response, or to the increase in local inflammation with resultant increased blood flow. Modern research has been limited but provides support for both arguments. Although there are no present indications for using radiation as therapy for infectious disease, a reasonable argument can be made from the available data that radiation is effective for the treatment of localized infections. The mechanisms of low-dose radiation as a treatment for infections remain unclear. The known and probable long-term sequelae of low-dose local irradiation preclude its common use for this condition. Nevertheless, it is hoped that this review will stimulate investigations into this relatively unexplored area of radiobiology.

(+info)A carbuncle is a deep, painful skin infection that involves a group of connected follicles and surrounding tissue, commonly caused by the bacterium Staphylococcus aureus, characterized by a core of necrotic tissue and multiple abscesses containing pus.
A carbuncle is a deep skin infection that often involves a group of hair follicles. It is a more severe form of a boil and can be quite painful. Carbuncles usually occur in people who have underlying health issues such as diabetes or a weakened immune system. They typically appear as red, swollen, and painful lumps on the skin that may release pus. Treatment for carbuncles usually involves antibiotics to clear up the infection and proper care of the wound to prevent complications.
