Mem. Inst. Oswaldo Cruz; 112 (3), 2017
BACKGROUND Haemophilus influenzae (Hi) serotype b (Hib) conjugate vaccine was incorporated into the infant immunisation schedule in Brazil in 1999, where Hib was one of the major etiologic sources of community-acquired bacterial meningitis. OBJECTIVES The purpose of this study is to describe the molecu...

Characterisation of iunH gene knockout strain from Mycobacterium tuberculosis

Mem. Inst. Oswaldo Cruz; 112 (3), 2017
BACKGROUND Tuberculosis (TB) is an infectious disease caused mainly by the bacillus Mycobacterium tuberculosis. The better understanding of important metabolic pathways from M. tuberculosis can contribute to the development of novel therapeutic and prophylactic strategies to combat TB. Nucleoside hydrol...

Tuberculosis associated factors caused by Mycobacterium tuberculosis of the RDRio genotype

Mem. Inst. Oswaldo Cruz; 112 (3), 2017
BACKGROUND Tuberculosis (TB) continues to be a disease that affects many countries around the world, including Brazil. Recently, a subtype of Latin American-Mediterranean family strain was identified and characterised by RDRio. The strain has been associated with different characteristics of the disease...

Epidemiología molecular de aislados clínicos de Klebsiella pneumoniae productores de carbapenemasas tipo KPC provenientes de dos hospitales públicos en los estados Carabobo y Zulia, Venezuela

Invest. clín; 58 (1), 2017
Klebsiella pneumoniae productora de carbapenemasas tipo KPC es uno de los principales agentes causante de infecciones nosocomiales a nivel mundial. En Venezuela se han identificado aislados de esta bacteria, sin embargo, se conoce poco sobre su dispersión. El objetivo de este estudio fue realizar la epi...

The Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) identification versus biochemical tests: a study with enterobacteria from a dairy cattle environment

Braz. j. microbiol; 48 (1), 2017
Abstract Mastitis adversely affects milk production and in general cows do not regain their full production levels post recovery, leading to considerable economic losses. Moreover the percentage decrease in milk production depends on the specific pathogen that caused the infection and enterobacteria are ...

Abstract Tuberculosis (TB) is a chronic disease caused by bacteria belonging to the Mycobacterium tuberculosis complex (MtbC). This disease rarely affects dogs. Canine infections are usually caused by M. tuberculosis. Mycobacterium bovis infections are rare in dogs and associated with consumption of raw ...

Bacterial selection for biological control of plant disease: criterion determination and validation

Braz. j. microbiol; 48 (1), 2017
Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial com...
