See also Beta-lactam antibiotics The basic structure of the penicillins consists of a thiazolidine ring, the beta-lactam ring, and a side chain. The beta-lactam ring is essential for antibacterial activity. The side chain determines in large part the antibacterial spectrum and pharmacological properties of a particular penicillin. The rapid emergence of bacteria, particularly Staphylococcus aureus, that produce beta-lactamases (penicillinase) has been partly countered by the development of compounds that resist hydrolysis by beta-lactamases and compounds that are more active than …

Respiratory Bronchospasm may be a consequence of penicillin allergy. Acute severe dyspnea with cyanosis has also been observed without symptoms of bronchial obstruction or pulmonary edema. Specific mechanisms for such cases have yet to be identified. Allergic pneumonitis and transient eosinophilic pulmonary infiltrate (Loeffler’s syndrome) are rare. These syndromes have also been observed with penicillin hypersensitivity. In one case, an alveolar allergic reaction, probably due to ampicillin, showed features of an adult respiratory distress syndrome. Nervous system High doses of penicillins, …

Penicillin-induced hepatotoxicity may not be as uncommon as has been thought. There have been three reviews. The first was a comparison of the assessment of drug-induced liver injury obtained by two different methods, the Council for International Organizations of Medical Sciences (CIOMS) scale and the Maria & Victorino (M&V) clinical scale. Three independent experts evaluated 215 cases of hepatotoxicity reported using a structured reporting form. There was absolute agreement between the two scales in 18% of cases, but there was no agreement in cases of fulminant hepatitis or death. The authors concluded that the CIOMS instrument is more likely …

Genetic Modifications Leading To Antimicrobial Resistance To understand why antibiotics must be used judiciously, the physician needs to understand how bacteria are able to adapt to their environment. Point mutations can develop in the Deoxyribonucleic acid of bacteria as they replicate. These mutations occur in the natural environment, but are of no …

Definition Infections of the urinary tract represent a wide variety of clinical syndromes including urethritis, cystitis, prostatitis, and pyelonephritis. A urinary tract infection is defined as the presence of microorganisms in the urine that cannot be accounted for by contamination. The organisms have the potential to invade the tissues of the urinary tract and adjacent structures. Lower tract infections include cystitis (bladder), urethritis (urethra), prostatitis (prostate gland), and epididymitis. Upper tract …

Definition Intra-abdominal infections are those contained within the peritoneum or retroperitoneal space. Two general types of intra-abdominal infection are discussed throughout this chapter: peritonitis and abscess. Peritonitis is defined as the acute, inflammatory response of peritoneal lining to microorganisms, chemicals, irradiation, or foreign body injury. Peritonitis may be classified as either primary or secondary. With primary peritonitis, an intra-abdominal focus of disease may not be evident. In secondary peritonitis, a focal disease process is evident within the abdomen. An abscess is a purulent collection of fluid separated by a more or …

Definition Central nervous system infections include a wide variety of clinical conditions and etiologies: meningitis, meningoencephalitis, encephalitis, brain and meningeal abscesses, and shunt infections. The focus of this chapter is meningitis. Pathophysiology Infections are the result of hematogenous spread from a primary infection site, seeding from a parameningeal focus, reactivation from a latent site, trauma, or congenital defects in the central nervous system. central nervous system infections may be caused by a variety of …

The latter two are “long-acting” forms. Penicillin G is useful in the treatment of streptococcal infections due to S. pyogenes (group A), S. agalactiae (group B), S. pneumoniae, viridans streptococci, Corynebacterium diphtheria, N. meningitidis, many strains of N. gonorrhea, Treponema pallidum, and many anaerobic streptococci, such as peptococcus and peptostreptococcus. In combination with aminoglycosides, any penicillin G compounds can be used to treat enterococci and L. monocytogenes infections. These organisms cause …
