These data confirm the usefulness of studying nasopharyngeal colonization for monitoring the profile of invasive strains.
The Brazilian study assessed 4,169 pneumococcal invasive strains, and 878 of these were collected from patients with pneumonia from 2000 to 2005.
In other countries, although these serotypes also figure among the most prevalent,data concerns mostly invasive strains isolated from CSF and blood.
Surveillance studies show that,according to the 2008 CLSI criteria, invasive strains of S. pneumoniae isolated in Brazil are uniformly sensitive to penicillin level III evidence.
Invasive strains included 1 of 4 dog isolates, 4 of 16 non-human primate isolates(2 C. jejuni and 2 C. coli), 1 of 9 C. coli strains isolated from pigs, and 7 of 18 C. fetus subsp.
In the USA, the Active Bacterial Core Surveillance ABCs Report detected,among 3,514 invasive strains collected during 2007, a cefotaxime resistance rate of 6.9% IR 5.5 and FR 1.4.
When analyzing 768 invasive strains collected during 2006, among the 168 strains from patients with pneumonia, the authors found a penicillin-resistance rate of 39.3% IR 21.4% and FR 17.9.
In the state of Minas Gerais, local studies have revealed rates of 11.8% of oxacillin-resistant strains and 15.5% of penicillin-resistant pneumococcal invasive strains according to the traditional criteria.
When analyzing 874 pneumococcal invasive strains collected during 2007, among the 162 strains from patients with pneumonia, the authors found a penicillin resistance rate of 12.3% IR according to the current criterion.
Recently studies about this bactéria have focused on their usage as vehicles for the delivery of genic vaccines. for this, invasive strains of l. lactis have been developed in order to increase the delivery efficiency of these vaccines to host cells.
Of the 412 invasive strains collected from patients without meningitis during 2006 and 2007, there was a ceftriaxone resistance rate of 9% 37/412, which was divided into 8.7% of IR 36/412 and 0.3% of FR 1/412.
The challenges associated with antimicrobial resistance,biofilm formation and invasive strains inspired us to test the potential use of an organic polymer to kill antimicrobial resistant and intracellular pathogens.
For invasive strains, with the exception of those obtained from patients with meningitis, the proposed values are a MIC< 1.0 µg/ml for susceptibility, 2.0 µg/ml for intermediate resistance and> 4.0 µg/ml for total resistance.
This is a prospective, case series, laboratory surveillance study, whose laboratory data on serotyping andin vitro susceptibility to antimicrobial agents of pneumococcal invasive strains were collected from patients hospitalized at HC-UFU with diagnosis of pneumonia.
At the HIV clinic, colonization from invasive pneumococci was much lower andthe post vaccination study showed the almost complete disappearance of the invasive strains(6/93), mainly of the less common serotypes, which called the attention towards the increase of vigilance towards the monitoring of children colonization dynamics.
Thus, the goals of this study were the construction of the therapeutic plasmid pvalac:: dts: :il-4; the in vitro evaluation of its functionality and verification of the recombinant il-4 protein(ril-4) production and secretion;the obtainment of the noninvasive and invasive strains of l. lactis carrying the pvalac:: dts: :il-4 plasmid; and the evaluation of the recombinant strains therape.
The introduction of prophylaxis and vaccines, especially of conjugate vaccines, led to a significant reduction in mortality due to infectious processes in these patients, and in spite of continuedneed for surveillance and concern about the emergence of pneumococcal strains resistant to penicillin or invasive strains not covered by the vaccine, these preventive measures have been effective so far.
In order to find out new virulence genes, we made 1,800 random-transposons mutants of an apec invasive strain using the signature-tagged mutagenesis method.
Widening the study to include samples collected up to 1999, but restricted to children up to six years old, found a global rate of resistance of 20.7%, which value is similar to the 20% found in Salvador, Bahia,among 70 invasive pneumococcus strains collected from individuals aged between one month and 19.5 years.
Resistance to penicillin was detected in 15% of the strains tested, coinciding with the rate of 15.4% 14.5% with intermediate resistance and0.9% total described by Brandileone on evaluating 2,050 invasive pneumococcus strains, collected between 1993 and 1998, originating from 14 different Brazilian states.
