Silanol - A novel class of antimicrobial agent
Provedor de dados: Electronic Journal of Biotechnology
Autores: Kim,Yun-mi; Farrah,Samuel; Baney,Ronald H.
Recently, a significant amount of attention has been directed toward development of novel classes of biocides because of the potential for microbial contamination and infection risks to military personnel and in the general population. We have recently discovered a new and unexpected class of powerful biocides based upon compounds derived through simple chemistry from silicone intermediates, "silicon alcohols" called, silanols. One example is trialkylsilanols, R3SiOH. Antimicrobial tests were carried out against Gram-negative bacterium, Escherichia coli, and Gram-positive, Staphylococcus aureus, with silanols, t-butanol, and siloxanes. Trialkylsilanols were very effective biocides against Escherichia coli and Staphylococcus aureus. The number of viable...

INFECTIONS IN THE BITE SITE AFTER ENVENOMING  BY SNAKES OF THE Bothrops GENUS
Provedor de dados: Journal of Venomous Animals and Toxins
Autores: JORGE,M. T.; RIBEIRO,L. A.
Envenomation caused by snakes of the Bothrops genus produces a lesion in the bite site and can result in extensive necrosis. The dead tissue can be secondarily infected by bacteria that come from the snake, and the bacteria can be inoculated at the moment of the bite. The bacteria that most commonly cause infection are the enterobacteria, mainly Morganella morganii, Proteus rettgeri, Enterobacter sp., and Escherichia coli. Group D streptococci including here Enterococcus sp. and the Bacteroides sp. are also involved. Based on a study of the sensibility of these bacteria, it has been suggested that this infection must be treated with chloramphenicol, as a sole antimicrobial agent, or with the combinations of benzylpenicillin or ampicillin with...

Antimicrobials and renal failure in neutropenic patients
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: França,Monique Sedlmaier; Lima,Stella Sala Soares; Duclou,Caroline Naback; Goulart,Eugênio Marcos Andrade; Romanelli,Roberta Maia de Castro.
Antimicrobial treatment is often indicated to neutropenic patients. Although renal failure is a common complication of many antibiotics, no information could be found in the literature defining which are the best screening criteria for detecting renal injury. In this paper, the authors aim to assess the progress to renal failure in neutropenic patients on antimicrobial use and to compare different diagnostic criteria of renal failure in association to antimicrobial agents used. This is a cohort study conducted from February to August 2006 at the Hospital das Clínicas of the Universidade Federal de Minas Gerais, which included patients with neutropenia and antimicrobial therapy for the treatment of Healthcare Associated Infections notified by the Hospital...

In vitro biofilm forming potential of Streptococcus suis isolated from human and swine in China
Provedor de dados: Brazilian Journal of Microbiology
Autores: Dawei,Guo; Liping,Wang; Chengping,Lu.
Streptococcus suis is a swine pathogen and also a zoonotic agent. The formation of bioﬁlms allows S. suis to become persistent colonizers and resist clearance by the host immune system and antibiotics. In this study, biofilm forming potentials of various S. suis strains were characterized by confocal laser scanning microscopy (CLSM), scanning electron microscopy (SEM) and tissue culture plates stained with crystal violet. In addition, the effects of five antimicrobial agents on biofilm formation were assayed in this study. S. suis produced biofilms on smooth and rough surface. The nutritional contents including glucose and NaCl in the growth medium modulated biofilm formation. There was a significant difference in their biofilm-forming ability among all 46...

Antimicrobial susceptibility of Campylobacter sp strains isolated from calves with and without diarrhea in Minas Gerais state, Brazil
Provedor de dados: Brazilian Journal of Microbiology
Autores: Miranda,Karina Leite; Lage,Andrey Pereira.
The antimicrobial susceptibility of 25 Campylobacter sp strains isolated from calves with and without diarrhea - 7 C. coli, 16 C. fetus and 2 C. jejuni was studied by the disk diffusion method. Eleven antimicrobial agents were tested amikacin, ampicillin, kanamycin, chloramphenicol, erythromycin, gentamicin, neomycin, nitrofurantoin, penicillin G, tetracycline and sulfamethoxazole-trimethoprim. All Campylobacter sp strains were susceptible to amikacin, ampicillin, chloramphenicol, erythromycin, gentamicin, neomycin and nitrofurantoin. Three strains were moderately susceptible to kanamycin (2 C. coli and 1 C. fetus). All the strains were resistant to penicillin G. Two C. fetus strains were moderately susceptible to sulfamethoxazole-trimethoprim and 1 C....

In vitro antimicrobial susceptibility of staphylococci isolated from canine pyoderma in Rio de Janeiro, Brazil
Provedor de dados: Brazilian Journal of Microbiology
Autores: Penna,B.; Varges,R.; Medeiros,L.; Martins,G.M.; Martins,R.R.; Lilenbaum,W.
The study aimed to determine the etiology and antimicrobial resistance of staphylococci isolated from canine pyoderma. Samples were obtained from dogs with pyoderma and isolates were identified by biochemical reactions and tested for susceptibility to 15 antimicrobials. Thirty nine staphylococci isolates were obtained, and S. pseudintermedius was the most frequent (47.4%). All isolates showed resistance to at least one drug and 77.1% were multiresistant. The most effective drug was oxacillin. The study reports the alarming antimicrobial resistance of Staphylococcus isolated from canine pyoderma samples.
