When cultured on blood agar plates with added optochin antibiotic disk they show alpha-hemolytic colonies and a clear zone of inhibition around the disk indicating sensitivity to the antibiotic. Pneumococci are also bile soluble. Just like other streptococci they are catalase-negative. A Quellung test can identify specific capsular polysaccharides.Pneumococcal antigen (cell wall C polysaccharide) may be detected in various body fluids. Older detection kits, based on latex agglutination, added little value above Gram staining and were occasionally false-positive. Better results are achieved with rapid immunochromatography, which has a sensitivity (identifies the cause) of 70–80% and >90% specificity (when positive identifies the actual cause) in pneumococcal infections. The test was initially validated on urine samples but has been applied successfully to other body fluids. Chest X-rays can also be conducted to confirm inflammation though are not specific to the causative agent. Prevention
Due to the importance of disease caused by S. pneumoniae several vaccines have been developed to protect against invasive infection. The World Health Organization recommend routine childhood pneumococcal vaccination; it is incorporated into the childhood immunization schedule in a number of countries including the United Kingdom, United States, and South Africa. Treatment
Throughout history treatment relied primarily on β-lactam antibiotics. In the 1960s nearly all strains of S. pneumoniae were susceptible to penicillin, but more recently there has been an increasing prevalence of penicillin resistance especially in areas of high antibiotic use. A varying proportion of strains may also be resistant to cephalosporins, macrolides (such as erythromycin), tetracycline, clindamycin and the fluoroquinolones.
She further argues that vases showing "a boy standing perfectly still as a man reaches out for his genitals" indicate the boy may have been "psychologically immobilized, unable to move or run away." One vase shows a young man or boy running away from Eros, the Greek god of desire. Ancient Rome
In Latin, mos Graeciae or mos Graecorum ("Greek custom" or "the way of the Greeks") refers to a variety of behaviors the ancient Romans regarded as Greek, including but not confined to sexual practice. : 72   Homosexual behaviors at Rome were acceptable only within an inherently unequal relationship; male Roman citizens retained their masculinity as long as they took the active, penetrating role, and the appropriate male sexual partner was a prostitute or slave, who would nearly always be non-Roman. In Archaic and classical Greece, paiderasteia had been a formal social relationship between freeborn males; taken out of context and refashioned as the luxury product of a conquered people, pederasty came to express roles based on domination and exploitation. : 37, 40–41 et passim  Slaves often were given, and prostitutes sometimes assumed Greek names regardless of their ethnic origin; the boys (pueri) to whom the poet Martial is attracted have Greek names. The use of slaves defined Roman pederasty; sexual practices were "somehow Greek" when they were directed at "freeborn boys openly courted in accordance with the Hellenic tradition of pederasty".
