Since 2010 the 13-valent pneumococcal conjugate vaccine (PCV13) replaced the 7-valent vaccine (PCV7) as the leading pneumococcal vaccine used in children through the private sector. Although, neither of the PCVs were used significantly in adults, changes in adult invasive pneumococcal disease (IPD) were expected due to herd protection. We characterized n = 1163 isolates recovered from IPD in ad...

We report here the draft genome sequence of aStreptococcus pneumoniaestrain isolated in Monterrey, Mexico, MTY1662SN214, from a man with purpura fulminans. The strain belongs to the invasive and multidrug-resistant serogroup 19A, sequence type 320 (ST320). The draft genome sequence consists of 60 large contigs, a total of 2,069,474 bp, and has a G+C content of 39.7%.

Linear tetrapyrroles related to phytochrome (1) were prepared in enantiospecific fashion by a new strategy beginning with ring-B,C synthons of type 19 (bis-iododipyrrins). Rings A and D were elaborated by Pd(0)-mediated coupling of 19a with the appropriate alkyne acid or amide derivatives 9 and 20, followed by intramolecular cyclization (method C: BC + D + A --> ABCD).

The serotypes and susceptibilities to penicillin, macrolides, and clindamycin of 1,655 invasive isolates of Streptococcus pneumoniae recovered between 1979 and 2004 were determined. A precipitous decrease of 61% in the number of isolates was found following 2000, the year of 7-valent protein-conjugated pneumococcal vaccine (PCV7) introduction (139 versus 55 per 2-year period prior to versus aft...

OBJECTIVE Streptococcus pneumoniae is a common pathogenic cause of pediatric infections. This study investigated the serotype distribution, antimicrobial susceptibility, and molecular epidemiology of pneumococci before the introduction of conjugate vaccines in Shanghai, China. METHODS A total of 284 clinical pneumococcal isolates (270, 5, 4,3, and 2 of which were isolated from sputum, broncho...

the association of celiac disease and type i diabetes mellitus has been known for some time. this study was undertaken to investigate the prevalence of celiac disease (cd) in diabetic children and adolescents. eighty-seven patients (44 females, 43 males) aged 2- 18 years, with type i diabetes participated in this study. a group of 87 healthy unrelated girls and boys matched for age and gender s...
