2. Effects of Oral Oxytetracycline-Therapy on Wound Progression and Healing Following Aeromonas caviae Infection in Nile Tilapia (Oreochromis niloticus L.)
Abstract The effects of oral oxytetracycline (OTC)-therapy against Aeromonas caviae infection as well as the wound progression and healing in intramuscular (IM) and abrasion-immersion (AI) challenged Nile tilapia juveniles were evaluated. The IM challenge caused significantly (p < 0.05) high mortalities (90%) compared to AI challenge (40%). The mortalities r

4. Performance, blood parameters, and carcass yield of broiler chickens supplemented with Mexican oregano oil
ABSTRACT The objective of the current study was to evaluate performance, blood parameters, and carcass yield of broilers supplemented with Mexican oregano oil. A total of 162 one-day-old broilers were randomly distributed into three dietary treatments: control diet (without oregano oil or antibiotic); control diet + 0.25 g kg−1 of oxytetracycline; and cont

5. Influence of diabetes mellitus on the mineralization ability of two endodontic materials
Abstract The aim of this study was to evaluate the influence of diabetes mellituson tissue response and mineralization ability of Sealapex®and MTA Fillapex® sealers. Twenty-four Wistar rats were divided into two groups: diabetic and non-diabetic. The materials were placed in polyethylene tubes and implanted into dorsal connective tissue of rats for 7 and 3

6. Development of Fed-Batch Cultivation Strategy for Efficient Oxytetracycline Production by Streptomyces rimosus at Semi-Industrial Scale
ABSTRACTOxytetracycline (OTC) production byStreptomyces rimosus was studied in batch and fed-batch cultures in shake flask and bioreactor levels using semi-defined medium. First, the effect of glucose concentration on OTC production and growth kinetics was studied intensively. The optimal glucose concentration in the medium was 15 g/L. Higher glucose concent

7. Chemical products induce resistance to
Xanthomonas perforans in tomatoThe bacterial spot of tomato, caused by
Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolarBraz. J. Microbiol.. Publicado em: 21/07/2015

8. Differences in the antimicrobial susceptibility profiles of Moraxella bovis, M. bovoculi and M. ovis
The aim of this study was to determine the differences in the antimicrobial susceptibility profiles of Moraxella bovis, M. bovoculi and M. ovis. Thirty-two strains of Moraxella spp. isolated from cattle and sheep with infectious keratoconjunctivitis were tested via broth microdilution method to determine their susceptibility to ampicillin, cefoperazone, ceft

9. Role of wild birds as carriers of multi-drug resistant Escherichia coli and Escherichia vulneris
Emergence and distribution of multi-drug resistant (MDR) bacteria in environments pose a risk to human and animal health. A total of 82 isolates of Escherichia spp. were recovered from cloacal swabs of migrating and non-migrating wild birds. All bacterial isolates were identified and characterized morphologically and biochemically. 72% and 50% of isolates re

10. Effects of feeding metabolite combinations from lactobacillus plantarum on plasma and breast meat lipids in Broiler Chickens
The effects of feeding different doses of metabolite combination of L. plantarum RS5, RI11, RG14 and RG11 strains (Com3456) on cholesterol reduction in plasma and breast meat in broiler chickens and the possible mechanism was studied. A total of 504 male Ross broilers were grouped into 7 treatments and offered with different diets: (i) standard corn-soybean

11. Zoonotic potential of multidrug-resistant extraintestinal pathogenic Escherichia coli obtained from healthy poultry carcasses in Salvador, Brazil
The zoonotic potential to cause human and/or animal infections among multidrug-resistant extraintestinal pathogenic Escherichia coli from avian origin was investigated. Twenty-seven extraintestinal pathogenic E. coli isolates containing the increased survival gene (iss) were obtained from the livers of healthy and diseased poultry carcasses at two slaughterh

The frequent association of environmental aquatic contamination with vibriosis in humans suggests the need for systematic monitoring and study of environmental vibrio strains and their pathogenic potential and clinical significance. The objective of this study was to evaluate the diversity of vibrio species in four estuaries (Pacoti, ChorÃ, Pirangi and Jagu
