Clostridioides (Clostridium) difficile infection (CDI) is an evolving global healthcare problem, and owing to the diverse and dynamic molecular epidemiology of C. difficile, new strains continue to emerge. In Brazil, only two cases of CDI due to the so called hypervirulent PCR ribotype (RT) 027 belonging to clade 2 have ever been reported, whereas incidence of CDI due to another "hypervirulent" RT078 (clade 5) has not yet been reported.

Clostridium difficile infection (CDI) has become more refractory to standard therapy. We describe 4 patients with severe refractory CDI who were successfully treated with tigecycline. Symptoms improved within 1 week.

Atypical mycobacterial skin infections are difficult to diagnose owing to their aspecific histopathologic presentations and to the presence of few bacteria. Therefore, these infections are often not recognized. Molecular detection of mycobacterial DNA has proven to be useful in clinical samples.

Infections associated with Mycobacterium haemophilum are underdiagnosed because specific culture methods required for its recovery are not applied routinely. Using polymerase chain reaction (PCR) technology on fine needle aspirates and biopsied specimens from 89 children with cervicofacial lymphadenitis, we assessed the importance of M. haemophilum.

Of 45 Russian patients with late complement component deficiency (LCCD) who experienced one to five meningococcal infections, 31 were immunised with a meningococcal A/C/W135/Y polysaccharide vaccine and were followed for 3-8 years. Total and immunoglobulin (Ig) class specific concentration of antibodies to meningococcal polysaccharides in sera of LCCD patients increased significantly 1 month after vaccination and remained elevated for 3 years. Revaccination of LCCD patients 3 years after the first dose restored the total Ig concentrations to those observed 1 year after the first vaccination.

Background: Thirty-one Russian patients with late complement component deficiency (LCCD) who had experienced one to five meningococcal infections were immunized with meningococcal polysaccharide vaccine (A + C + W135 + Y) and were followed for 3-8 years. We investigated the potentially protective killing effect of human neutrophils (PMNL) on serogroup A and W135 meningococci.

Methods: Meningococci were incubated in LCCD vaccine sera in the absence or presence of PMNL, and the number of live bacteria (CFU) was determined by plating onto chocolate agar.
