Introduction Parasites live in a host from which they obtain food and protection. They may harm but usually do not benefit the host. The word “parasite” is derived from the Latin and Greek languages meaning, in general, “one who eats at the table of another.” It is said that a “good” parasite does not overtly harm or kill its host. It is theoretically possible that a more benign parasite (e.g. ...

The odd composite n < 25 • 10 such that 2n_1 = 1 (mod n) have been determined and their distribution tabulated. We investigate the properties of three special types of pseudoprimes: Euler pseudoprimes, strong pseudoprimes, and Carmichael numbers. The theoretical upper bound and the heuristic lower bound due to Erdös for the counting function of the Carmichael numbers are both sharpened. Several...

LTX-109 and eight other antimicrobial agents were evaluated against 155 methicillin-resistant Staphylococcus aureus (MRSA) isolates, including strains resistant to vancomycin and strains with decreased susceptibility to daptomycin and linezolid, by microdilution tests to determine MICs. Time-kill assays were performed against representative MRSA, vancomycin-intermediate S. aureus (VISA), and va...

Nasal decolonization has a proven effect on the prevention of severe Staphylococcus aureus infections and the control of methicillin-resistant S. aureus (MRSA). However, rising rates of resistance to antibiotics highlight the need for new substances for nasal decolonization. LTX-109 is a broad-spectrum, fast-acting bactericidal antimicrobial drug for topical treatment, which causes membrane dis...
