Biofilm formation and antimicrobial resistance of Staphylococcus aureus are important virulence factors in cases of mastitis in dairy cows. However, few studies have investigated mastitis strains isolated from heifers. Within this context, the objective of the present study was to investigate biofilm formation on Congo red agar, the presence of the icaA and icaD genes by polymerase chain reaction (PCR), and the percentage of in vitro antimicrobial resistance of 110 S.

Results: Fifty samples (five collections of ten samples each) of sorghum were analysed. All samples were found to be contaminated with fungi, with higher frequencies of Cladosporium spp.
Background: Because of co-morbidity, older persons are often exposed to use of an excessive number of drugs, which per se implies also use of inappropriate drugs or of potentially interacting drugs ('suboptimal prescribing'). Time trends of suboptimal prescribing in older, community dwellers have been poorly investigated, particularly in Italy.
Objective: To evaluate the time-course modification of suboptimal prescribing in older, community dwellers.
Background: Subtle, but clinically detectable, neurological abnormalities (SNAs) are associated with impaired physical performance in elderly persons without overt neurological diseases. We investigated whether SNAs were prospectively associated with cognitive and functional status, death, and cerebrovascular events (CVEs) in older community-dwelling individuals.
Methods: In participants without history of stroke, parkinsonism and dementia, or cognitive impairment, a score (N(SNA)) was obtained by summing SNAs detected with a simple neurological examination.
Brain microangiopathy, whose neuroimaging expression is represented by age-related white matter changes (ARWMC), is largely due to hypertension and it is, in turn, responsible for geriatric syndromes, including decline in cognitive, functional and motor/gait abilities. This review analyzes the link between hypertension and ARWMC, as well as the complex relationships between ARWMC and cognitive impairment, executive dysfunction, and movement/gait abnormalities. The available evidence supports the hypothesis that these functional consequences of ARWMC are responsible for substantial disability in the elderly.

Design: An assessment of the data obtained from the Insufficienza Cardiaca negli Anziani Residenti a Dicomano (ICARe Dicomano) Study, a longitudinal epidemiological survey on heart failure in older people.
Setting: Dicomano, a small, rural town near Florence, Italy.
The present study aimed to analyze the mycoflora and the occurrence of alternariol (AOH) and alternariol monomethyl ether (AME) in grain samples of sunflower during different stages of plant development in Nova Odessa, State of São Paulo, Brazil. The data obtained were correlated with the presence of fungi in soil, wind-dispersed fungi, and the predominant climatic conditions of the region where the experiment was carried out. Analysis of the mycoflora revealed the presence of Fusarium verticillioides and Alternaria alternata in 70% and 46% of the samples, respectively.

Background: The prevalence estimates of HF vary broadly depending on the diagnostic criteria.
Methods: Data were collected in a survey of community dwellers who were > or =65 years of age living in Dicomano, Italy.
Objectives: To assess whether kyphosis is associated with ventilatory dysfunction in older community dwellers.
Design: Cross-sectional study.
Setting: The unselected population of Dicomano, Italy aged>or=65 years.
