1. Pneumonias com e sem ventilação mecânica em neonatos críticos internados em uma UTI neonatal de um hospital universitário brasileiro : aspectos clínicos, radiológicos e microbiológicos
Although pneumonia is considered serious and frequent in NICU, there are few studies, mainly about those associated to mechanical ventilation. The aim of the study was epidemiological, considering the evaluation of pneumonia associated or not to mechanical ventilation diagnosed by clinical, radiological and microbiological in critically neonates hospitalized

3. Polymorphism of Repeated Regions of Pertactin in Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica
Pertactin is an outer membrane protein expressed by Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica that induces protective immunity to Bordetella infections. The immunodominant and immunoprotective epitopes of pertactin include two repeated regions, I and II. Comparison of these two repeated regions showed that B. parapertussis

4. Serum Immunoglobulin G Antibody Responses to Bordetella pertussis Lipooligosaccharide and B. parapertussis Lipopolysaccharide in Children with Pertussis and Parapertussis
Serum immunoglobulin G (IgG) antibodies against the lipooligosaccharide (LOS) of Bordetella pertussis and the lipopolysaccharide (LPS) of Bordetella parapertussis were measured by enzyme-linked immunosorbent assay in paired sera from 40 children with pertussis and 14 with parapertussis. Wide differences in the individual responses were noted. Both anti-LOS a

5. Bordetella pertussis and Bordetella parapertussis: two immunologically distinct species.
Bordetella pertussis and Bordetella parapertussis are closely related species. Both are responsible for outbreaks of whooping cough in humans and produce similar virulence factors, with the exception of pertussis toxin, specific to B. pertussis. Current pertussis whole-cell vaccine will soon be replaced by acellular vaccines containing major adhesins (filame

6. Bordetella parapertussis and Bordetella bronchiseptica contain transcriptionally silent pertussis toxin genes.
Pertussis toxin, the major virulence factor of Bordetella pertussis, is not produced by the closely related species Bordetella parapertussis and Bordetella bronchiseptica. It is shown here that these two species possess but do not express the complete toxin operon. Nucleotide sequencing of an EcoRI fragment of 5 kilobases comprising the regions homologous to

7. Role of Systemic and Mucosal Immune Responses in Reciprocal Protection against Bordetella pertussis and Bordetella parapertussis in a Murine Model of Respiratory Infection
The roles of systemic humoral immunity, cell-mediated immunity, and mucosal immunity in reciprocal protective immunity against Bordetella pertussis and Bordetella parapertussis were examined by using a murine model of respiratory infection. Passive immunization with serum from mice infected with B. pertussis established protective immunity against B. pertuss

8. Moredun Bordetella Medium, an improved selective medium for isolation of Bordetella parapertussis.
Bordetella parapertussis, previously thought to be an obligate human respiratory tract pathogen, has been isolated from sheep. Attempts to assess the prevalence of B. parapertussis in conventionally reared sheep by nasal swabbing proved futile with existing selective media because of extensive overgrowth with Mucor spp. and other nasal commensals. Moredun Bo

9. Evaluation of Real-Time PCR for Detection of and Discrimination between Bordetella pertussis, Bordetella parapertussis, and Bordetella holmesii for Clinical Diagnosis
PCR is increasingly being used as a diagnostic test for the detection of Bordetella pertussis and Bordetella parapertussis DNA, as it has improved sensitivity and specificity in comparison to conventional techniques. The assay described here uses the two insertion sequences IS481 and IS1001 for B. pertussis and B. parapertussis, respectively, with detection

10. In vitro susceptibilities of Bordetella pertussis and Bordetella parapertussis to four fluoroquinolones (levofloxacin, d-ofloxacin, ofloxacin, and ciprofloxacin), cefpirome, and meropenem.
The in vitro activities of levofloxacin, ofloxacin, d-ofloxacin, ciprofloxacin, cefpirome, and meropenem against 34 clinical isolates each of Bordetella pertussis and Bordetella parapertussis were determined by agar dilution on Mueller-Hinton agar supplemented with 5% horse blood. Levofloxacin was as active as ciprofloxacin against both species (MIC, 0.06 mi

11. Reciprocal Protective Immunity against Bordetella pertussis and Bordetella parapertussis in a Murine Model of Respiratory Infection
The protective immunity induced by infection with Bordetella pertussis and with Bordetella parapertussis was examined in a murine model of respiratory infection. Convalescent mice that had been infected by aerosol with B. pertussis or with B. parapertussis exhibited a protective immune response against B. pertussis and also against B. parapertussis. Anti-fil

12. Bordetella parapertussis Infection in Children: Epidemiology, Clinical Symptoms, and Molecular Characteristics of Isolates
The clinical trial conducted in Italy to evaluate the efficacy of acellular pertussis vaccines provided an opportunity to estimate the frequency of clinical infections with Bordetella parapertussis and to compare the clinical characteristics of children suffering from Bordetella pertussis illness with those of children with B. parapertussis illness.
