Nosocomial infections in intensive care and medical rehabilitation units, and evaluation of antibiotics prescription

Although, nosocomial infections (NIs) are considered to be an important cause of mortality and prolonged stay in hospitals, there are only a few studies that are concerned with their prevention and reduction in rehabilitation units. This could be because most NI surveys have been carried out mainly in acute and long-stay in hospitals. As a result, limited information is available on prevention and reduction of NIs in...

Microbiological study of ventilator associated pneumonia with antimicrobial susceptibility pattern of the isolated strains and its relation to nasal colonization in neonatal intensive care unit

The aim of this study is to analyze the microbiological profile of ventilator associated pneumonia (VAP) in relation to nasal swabs and prevalence of multi-drug resistant bacteria so as to implement effective treatment and prevention strategies in NICU (Neonatal Intensive Care Unit). One hundred neonates were ventilated for more than 48 h and met the inclusion criteria which were enrolled in the study. All cases were...

Antimicrobial activity of selected plant species and antibiotic drugs against Escherichia coli O157:H7

Recent research has focused on natural plant products as alternative for disease control in both developed and developing countries. Medicinal plants can be a possible source for new potent antimicrobial agents to which pathogenic strains are not resistant. The present study was carried out to determine the in vitro antimicrobial activity of 14 plant species namely; Allium sativum, Aloe vera, Bryophyllum pinnatum,...

Comparative assessment of Ni and As(III) mediated alterations in diazotrophic cyanobacteria, Anabaena doliolum and Anabaena sp. PCC7120

The comparative effects of nickel (Ni2+) and arsenite (As(III)) on two diazotrophic cyanobacterial species were investigated in terms of photosynthetic attributes. Both metals demonstrated inhibitory effects on growth, pigments (chl a and phycocyanin) and photosystem II (PS II) photochemistry. However As(III) exerted severe effects as compared to Ni reflected by (1) reduced growth (2) significant inhibition of chl a and...

Efficient production of second generation ethanol and xylitol by yeasts from Amazonian beetles (Coleoptera) and their galleries

Beetles of the Passalidae family live and feed on decaying wood and their guts are richly colonized by yeasts. The goal of this research was to prospect xylolytic yeasts with potential for the production of second-generation bioethanol. Therefore, 83 specimens of beetles belonging to the Passalidae and the Scarabaeidae families were collected in the Amazonian rainforest in Itacoatiara - AM, Brazil. Morphological...
