Antivirulence Bispecific Monoclonal Antibody-Mediated Protection against Pseudomonas aeruginosa Ventilator-Associated Pneumonia in a Rabbit Model.

Ventilator-associated pneumonia is an important clinical manifestation of the nosocomial pathogen Pseudomonas aeruginosa. We characterized the correlates of protection with MEDI3902, a bispecific human IgG1 monoclonal antibody that targets the P. aeruginosa type 3 secretion system PcrV protein and the Psl exopolysaccharide, in a rabbit model of ventilator-associated pneumonia using lung-protective, low-tidal-volume mechanical ventilation.

MEDI3902 Correlates of Protection against Severe Pseudomonas aeruginosa Pneumonia in a Rabbit Acute Pneumonia Model.

is among the most formidable antibiotic-resistant pathogens and is a leading cause of hospital-associated infections. With dwindling options for antibiotic-resistant infections, a new paradigm for treatment and disease resolution is required. MEDI3902, a bispecific antibody targeting the type III secretion (T3S) protein PcrV and Psl exopolysaccharide, was previously shown to mediate potent protective activity in murine infection models.

Combination of different methods for detection of Campylobacter spp. in young children with moderate to severe diarrhea.

Campylobacter spp. were detected - using culture, ELISA, PCR, and qPCR - among children (0-36months) with moderate to severe diarrhea in Northeastern Brazil. Our data showed that either the qPCR alone or PCR along with ELISA might be an alternative to culture to diagnose Campylobacter due to their enhanced sensitivity.

Campylobacter jejuni and Campylobacter coli in children from communities in Northeastern Brazil: molecular detection and relation to nutritional status.

This study determined the prevalence of Campylobacter jejuni/coli and its relation with nutritional status in children from Northeastern Brazil. This was a case-control study design. Stool samples were evaluated for hipO (C.

Antigenicity of a whole parasite vaccine as promising candidate against canine leishmaniasis.

Human visceral leishmaniasis, one of the most important zoonoses, is caused by the protozoa Leishmania chagasi (syn. L. infantum) and is present as a fatal disease common in South America and Europe where dogs and wild canids are the main reservoirs.
