An alternative for antibiotic se in poultry: probiotics Rev. Bras. Ciênc. Avic.
Edens,FW.
Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic usage in livestock and poultry. Therefore, alternatives to the use of growth promoting antibiotics must be found to promote growth or production at or near the genetic potential of the modern day broiler, turkey, and egg producer. The use of probiotics has many potential benefits and include modified host metabolism, immuno-stimulation, anti-inflammatory reactions, exclusion and killing of pathogens in...

ANTAGONISTIC EFFECT OF EDIBLE MUSHROOM EXTRACT ON CANDIDA ALBICANS GROWTH BJM
Paccola,Edneia A. de Souza; Maki,Cristina Sayuri; Nobrega,Gisele M.A. de; Paccola-Meirelles,Luzia Doretto.
Five species of edible mushrooms, Lentinula edodes, Pleurotus ostreatus, Pholiota nameko, Macrolepiota bonaerensis and Agaricus blazei, were tested for their potential to inhibit the in vitro growth of the pathogenic yeast Candida albicans. Only L. edodes had a fungistatic effect on this human pathogen. The inhibitory compound was produced intra and extracellularly in submersed L. edodes culture, and was also present in fresh and dehydrated mushroom basidiocarps. The fungistatic compound was heat sensitive and lost activity after 72 hours.

Antibiotic resistance and integrons in Shiga toxin-producing Escherichia coli (STEC) BJM
Colello,Rocío; Etcheverría,Analía I.; Conza,Jose A. Di; Gutkind,Gabriel O.; Padola,Nora L..
Shiga toxin-producing Escherichia coli (STEC) cause hemorrhagic colitis (HC) and hemolytic-uremic syndrome in humans (HUS). Cattle are the main reservoir of STEC and transmission to humans occurs through contaminated food and water. Antibiotics are used in pig production systems to combat disease and improve productivity and play a key role in the dissemination of antibiotic resistance genes to the bacteria. Integrons have been identified in resistant bacteria allowing for the acquisition and dissemination of antibiotic resistance genes. STEC strains isolated from humans and animals have developed antibiotic resistance. In our laboratory, 21 non-157 STEC strains isolated from pigs were analyzed to detect class 1 and 2 integrons by PCR. Eight carried...

Antibiotic susceptibility of Moraxella bovis recovered from outbreaks of Infectious Bovine Keratoconjunctivitis in Argentina, Brazil and Uruguay between 1974 and 2001 BJM
Conceição,Fabricio Rochedo; Bertoncelli,Diane Maria; Storch,Otávio Brod; Paolicchi,Fernando; Cobo,Ana Lia; Gil-Turnes,Carlos.
Antibiotic susceptibility of thirty Moraxella bovis strains recovered from outbreaks of Infectious Bovine Keratoconjunctivitis (IBK) in Argentina, Brazil and Uruguay between 1974 and 2001 was determined using the Kirby-Bauer and the Minimal Inhibitory Concentration (MIC) methods. Our results suggest that most strains were susceptible to the antibiotics used in the treatment of IBK, and that the antibiotic susceptibility of M. bovis varied with the geographical region and period of recovery.

Antibiotics for the empirical treatment of acute infectious diarrhea in children BJID
Diniz-Santos,Daniel R.; Silva,Luciana R.; Silva,Nanci.
While the routine use of antibiotics for infectious diarrhea in children must be avoided, because it brings little benefit in most cases and is associated with the risk of increasing antimicrobial resistance, selected cases may require antimicrobial therapy, and the choice of the antimicrobial agent often has to be made empirically. Physicians prescribing antimicrobials in such a setting have not only to be aware of the most likely pathogens, but also of their characteristic antimicrobial susceptibility pattern and the safety profile of the various drugs. We reviewed the literature on the use of ampicillin, beta-lactamase inhibitors, trimethoprim-sulfamethoxazole, chloramphenicol, tetracyclines, nalidixic acid, fluoroquinolones, third-generation...

Antibiotics produced by Streptomyces BJID
Procópio,Rudi Emerson de Lima; Silva,Ingrid Reis da; Martins,Mayra Kassawara; Azevedo,João Lúcio de; Araújo,Janete Magali de.
Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals, antivirals, antitumorals, anti-hypertensives, immunosuppressants, and especially antibiotics. The production of most antibiotics is species specific, and these secondary metabolites are important for Streptomyces species in order to compete with other microorganisms that come in contact, even within the same genre. Despite the success of the discovery of antibiotics,...

Antimicrobial susceptibility of Clostridium perfringens strains isolated from broiler chickens BJM
Silva,R. O. S.; Salvarani,F.M.; Assis,R.A.; Martins,N.R.S.; Pires,P.S.; Lobato,F.C.F..
Clostridium perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen that causes necrotic enteritis and colangio hepatitis. The minimum inhibitory concentration (MIC) of seven different compounds used for therapy, growth promotion or prevention of coccidiosis was determined by agar dilution method for 55 C. perfringens strains isolated from the intestines of broiler chickens. All strains showed high susceptibility to penicillin, avilamycin, monensin and narasin. Only 7.3% of the strains showed an intermediated sensitivity to lincomycin, and 49 (89.1%) were considered susceptible. For tetracycline and bacitracin, 41.8% and 47.3% of strains, respectively, were considered resistant.

Assessment of an intervention aimed at early discontinuation of intravenous antimicrobial therapy in a Brazilian University hospital BJID
Bonella,Gislaine Ferraresi; Fontes,Astrídia Marília de Souza; Jorge,Miguel Tanús; Silveira,Alexandre Barcelos Morais da.
Abstract Many interventions demonstrate success in adapting the duration of intravenous antibiotic therapy, but few studies have been conducted in developing countries. The aim of this study was to evaluate the effectiveness of an intervention in the induction of early discontinuation of intravenous antimicrobial therapy and/or its switch to oral therapy. The study employed a before–after intervention design that consisted of displaying a message in the computerized prescription on the third day and suspension of the prescription on the fifth day of intravenous antimicrobial therapy. A total of 465 patients were followed during the control period (CP) and 440 in the intervention period (IP). The intravenous therapy was switched to oral therapy for 11...

Biodiversity of Antimicrobial-Producing Actinomycetes Strains Isolated from Dry Dipterocarp Forest Soil in Northeast Thailand BABT
Chanthasena,Panjamaphon; Nantapong,Nawarat.
The increasing use of antibiotics has led to the development of drug-resistant microorganisms. The emergence of resistant strains has compromised the treatment and control of infectious diseases. As a result, the search and development of a novel class of antibiotic drugs are required. Actinomycetes have been recognized as a richest source of secondary metabolites including antibiotics. The aim of this study was to investigate the diversity of antibiotic-producing soil Actinomycetes from dry dipterocarp forest in Northeast of Thailand. The soil from this area has been known for its poor in nutrients and highly acidic with pH values around 4.5. In such a harsh condition, soil-inhabiting Actinomycetes elevate their protective mechanisms by inducing the...

Challenges in the development of drugs for the treatment of tuberculosis BJID
Shehzad,Adeeb; Rehman,Gauhar; Ul-Islam,Mazhar; Khattak,Waleed Ahmad; Lee,Young Sup.
Tuberculosis infection is a serious human health threat and the early 21st century has seen a remarkable increase in global tuberculosis activity. The pathogen responsible for tuberculosis is Mycobacterium tuberculosis, which adopts diverse strategies in order to survive in a variety of host lesions. These survival mechanisms make the pathogen resistant to currently available drugs, a major contributing factor in the failure to control the spread of tuberculosis. Multiple drugs are available for clinical use and several potential compounds are being screened, synthesized, or evaluated in preclinical or clinical studies. Lasting and effective achievements in the development of anti-tuberculosis drugs will depend largely on the proper understanding of the...
