Murine microglial cultures were stimulated with agonists for TLR1/2 (Pam3CSK4), TLR4 (lipopolysaccharide), and TLR9 (CpG oligodeoxynucleotide) for 24 h and then exposed to either the encapsulated D39 (serotype 2) or the nonencapsulated R6 strain of S. pneumoniae. After stimulation, the levels of interleukin-6 and CCL5 (RANTES [regulated upon activation normal T-cell expressed and secreted]) were increased, confirming microglial activation. The TLR1/2, -4, and -9 agonist-stimulated microglia ingested significantly more bacteria than unstimulated cells (P < 0.05). The presence of cytochalasin D, an inhibitor of actin polymerizaton, blocked >90% of phagocytosis. Along with an increased phagocytic activity, the intracellular bacterial killing was also increased in TLR-stimulated cells compared to unstimulated cells. Together, our data suggest that microglial stimulation by these TLRs may increase the resistance of the brain against pneumococcal infections."],["dc.identifier.doi","10.1128/IAI.01110-09"],["dc.identifier.isi","000273855600033"],["dc.identifier.pmid","19933834"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/20648"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Soc Microbiology"],["dc.relation.issn","0019-9567"],["dc.title","Toll-Like Receptor Stimulation Enhances Phagocytosis and Intracellular Killing of Nonencapsulated and Encapsulated Streptococcus pneumoniae by Murine Microglia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

At concentrations above the minimal inhibitory concentration, the protein-synthesis-inhibiting antibiotics erythromycin, clindamycin and rifampicin inhibit the production and/or release of virulence factors in various bacterial species. We investigated the influence of subinhibitory concentrations of these antibiotics on production and release of pneumolysin by S. pneumoniae strain D39. Methods: The pneumococcal strain D39 was grown in broth and treated with antibiotics at a concentration of 1/32 of the respective minimal inhibitory concentration. Cytoplasmic and extracellular pneumolysin was measured by quantitative immunoblotting with recombinant pneumolysin as standard. Results: The subinhibitory antibiotic concentrations evaluated did not affect bacterial growth. During logarithmic growth, production of pneumolysin was decreased by clindamycin, erythromycin and rifampicin by approximately 50% compared with untreated controls. The release of pneumolysin was decreased to a similar extent. Conclusion: A decrease in pneumolysin production by 50% probably has a moderate biological effect. We do not advocate the use of subinhibitory concentrations of antibiotics to modulate the expression of virulence factors during pneumococcal disease, particularly with regard to the risk of development of antibiotic resistance.

Lyme disease is the most frequent tick-borne infectious disease in Europe affecting the skin, joints, heart, nervous system and rarely the eyes. Since the discovery of the causative pathogen Borrelia burgdorferi 30 years ago, the rapid accumulation of knowledge about this disease has resulted in well-evaluated clinical and microbiological diagnostic guidelines. Today, neuroborreliosis can generally be diagnosed and treated successfully. Progress in microbiological research has led to improved serological tests with higher sensitivity and new approaches for early diagnosis of Lyme disease. Erythema migrans is the most frequent manifestation of Borrelia infection. It is diagnosed clinically. Neuroborreliosis is diagnosed by the combination of typical neurological symptoms, cerebrospinal fluid pleocytosis and Borrelia-specific antibodies produced intrathecally. In adults, erythema migrans is treated with doxycycline, in children with amoxicillin. Standard treatment of neuroborreliosis is ceftriaxone or cefotaxime i.v. Recent studies show similar efficacy of oral doxycycline in early neuroborreliosis. An appropriate antibiotic treatment eliminates the pathogen effectively. Repeated episodes of acute manifestations of Lyme disease in treated patients are probably due to reinfection and not to relapse. Only in a small proportion of treated patients is recovery from neuroborrelioses incomplete.
