| Nosocomial infections caused by methicillin-resistant staphylococci (MRSA) pose a serious problem in many countries. This study aimed to determine the antibacterial susceptibility patterns of methicillin sensitive and resistant Staphylococcus aureus isolates from the hospitalized patients. Totally 356 isolates of Staphylococcus aureus (S. aureus) including 200, 137 and 19 corresponding to MSSA, MRSA, and intermediate MRSA strains, respectively were isolated. Antibacterial susceptibility patterns of the isolates to 14 antibiotics were examined using Kirby-Bauer method. MICs of 15 antibiotics to 156 MRSA isolates were determined by E test method. Cross-resistances of MRSA isolates (137+19) to the other tested antibiotics were also determined. S.aureus with... |

| In this study, we present antifungal susceptibility data of clinical and environmental isolates of Central Indian Cryptococcus neoformans (Serotype A, n = 8 and n = 50 respectively) and Cryptococcus gattii (Serotype B, n = 01 and n = 04 respectively). Susceptibilities to fluconazole, itraconazole and ketoconazole were determined by using NCCLS broth micro-dilution methodology. The total number of resistant strains for fluconazole in case of C. neoformans and C. gattii showed a significant difference by using chi-square test (p < 0.05*), while considering fisher's exact p value was nonsignificant (p > 0.05). However, the total number of resistant strains for itraconazole and ketoconazole was not found statistically significant. A comparison of... |

| The aim of present study was the assessment of antimicrobial activity of prepared time-dependent release bilayer tablets of amoxicillin trihydrate and in vitro evaluation of drug release by antimicrobial assay using agar plate diffusion method. The bilayer tablets comprised of a delayed and sustained release layer. Direct compression method was used for the preparation of bilayer tablets containing Eudragit-L100 D55 as delayed release polymer, and HPMCK4M and HPMCK15 as sustained release polymers. The prepared bilayer tablets containing amoxicillin trihydrate were evaluated for hardness, thickness, friability, weight variation and drug content. Further, in vitro drug release was assessed by antimicrobial assay using S. aureus and E. coli as test... |

| Abstract: Pasteurella (P.) multocida is the causative agent of pneumonic pasteurellosis in swine, which is commonly associated with the final stages of enzootic pneumonia or porcine respiratory disease complex. Although this syndrome is one of the most common and important diseases of pigs, data on antimicrobial susceptibility of P. multocida isolates are uncommon in Brazil. Therefore, the present study was carried out to determine and to compare antimicrobial susceptibility profile of Brazilian P. multocida isolated from pigs with lesions of pneumonia or pleuritis during two-time periods. Historical isolates (period of 1981 to 1997; n=44) and recent isolates (period of 2011 to 2012; n=50) were used to determine the MIC of amoxicillin, enrofloxacin,... |

| Resumo: O objetivo deste trabalho foi apresentar uma revisão sobre a atividade do óleo essencial de Cinnamomum. cassia contra Staphylococcus aureus por meio de pesquisas nas bases Web of Science, Science Direct, Scopus, Lilacs e Medline. Para tanto, foram utilizados artigos que abordam os componentes químicos do óleo essencial (OE) de Cinnamomum cassia e sua atividade contra Staphylococcus aureus por meio de dados de diâmetro de inibição, Concentração Inibitória Mínima (CIM) e Concentração Bactericida Mínima (CBM), publicados entre 2011 a 2021. De 98 estudos identificados, 26 preencheram os critérios de inclusão. Os componentes químicos mais comumente encontrados no óleo essencial de C. cassia foram nesta ordem; cinamaldeído, na forma Trans/E, acetato de... |

| The Achillea millefolium L. is a perennial herb with important antibacterial, antifungal, anti-inflammatory, antitumoral, and antioxidant properties. This research aimed to investigate the effect of shading (75%; black net) and nitrogen fertilization (0, 75 and 150 kg urea ha-1) on the nitrogen metabolism, essential oil yield and antimicrobial activity of A. millefolium at vegetative- and reproductive-stage. The evaluated parameters varied depending on the organ and the phenological stage of the plant considered. Overall, our findings indicated that shading decreased nitrogen assimilation. Decreased activities of nitrate reductase and glutamine synthetase were observed on shaded plants during reproductive and vegetative stages, respectively. Nitrate and... |

| We examined epidemiological aspects and bacterial resistance patterns of bacteria isolated from intensive care unit (ICU) patient samples. During a 10 month period (from June 2006 to March 2007), 812 samples of blood, urine and cerebral spinal fluid (CSF) from 553 hospitalized patients, in ICU wards, including pediatric surgical, neonatal, adult surgical I, adult surgical II, general pediatrics, neurosurgical I, neurosurgical II, and internal medical, were collected. Minimum inhibitory concentration (MIC) of antibiotics for bacteria isolates was determined by the E-test method. The internal medicine ICU with 28.7% admissions gave the largest contribution. Coagulase negative staphylococci at frequencies of 66.7 % and 36.5 % and E. coli at 20.9% were the... |

| Rhodococcus equi infection treatment is usually a macrolide (azithromycin - AZM, clarithromycin - CLR and erythromycin - ERY) and rifampicin combination. However, resistance cases have been reported, especially for ERY. In view of the need of a study about Brazilian isolates susceptibility profile, this study aimed to characterize the minimum inhibitory concentration (MIC) of the macrolides - AZM, CLR and ERY - against 44 R. equi isolates. It was found all isolates CLR and AZM sensitive; however, for ERY, 27% (12/44) were classified as intermediate sensitivity. R. equi Brazilian isolates used here showed a large susceptibility profile, except against ERY, for which it was observed some resistance evidence. In order to avoid failures in the equine... |
