Entomopathogenic nematodes (genera Steinernema and Heterorhabditis) can control a wide variety of economically important pests (Shapiro-Ilan et al., 2002), and are generally applied in aqueous suspension through a variety of agricultural spray equipment or irrigation systems (Grewal, 2002). These nematodes have also been shown to be effective when applied in their infected-host cadavers (Creigh...

one of the main problems in micro irrigation system is inappropriate combination and in some cases inappropriate performance of filters and sand tanks in central control systems which cause reduction in efficiency of system and increasing of operating costs. this study evaluates affect the amount of algae on the performance of disc filters sand tank in research farm deputy of soil and water and...

Abstract Beginning with the existing irrigation technique used in cotton farming, this paper aims to compare outcomes of using drip traditional irrigation. There are advantages for field aimed at saving water and other resources, which is demonstrated by example decreasing percent losses increasing outputs crop yields. Such conditions allowed collecting resources per hectare productivity, consu...

BACKGROUND Electrical Impedance measurements can be used to estimate the content of intra-thoracic air and thereby give information on pulmonary ventilation. Conventional Impedance measurements mainly indicate relative changes, but no information concerning air-volume is given. The study was performed to test whether a 3-point-calibration with known tidal volumes (VT) during conventional mechan...

In line with a rapid de-escalation of empirical antimicrobial therapy, this study assessed the validity of an E-test-based direct specimen testing method on bronchoalveolar lavage (BAL) samples from ventilator-associated pneumonia (VAP) patients. E-test strips were directly applied onto Mueller-Hinton agar plates seeded with BAL samples and read after 24 h of incubation. In parallel, the BAL sa...

The importance of predefined criteria for acceptable samples of respiratory therapists obtained lower respiratory samples were studied, using a nonbronchoscopic bronchoalveolar lavage (BAL) protocol for ventilated patients in the intensive care unit. Therapists were instructed and asked to follow guidelines for obtaining samples. Over one year, 219 samples were obtained by respiratory therapist...

We report a case of non-ventilator-associated nosocomial pneumonia and septicemia due to Dolosigranulum pigrum, a rare gram-positive opportunistic pathogen. The organism was isolated from bronchoalveolar lavage fluid and blood of a debilitated patient. D. pigrum was identified after 16S rRNA gene sequencing.

Intervention: Using a 2-by-2 factorial design, subjects were randomly assigned to a) undergo bronchoalveolar lavage with quantitative culture of the bronchoalveolar-lavage fluid or endotracheal aspiration with nonquantitative culture of the aspirate, and to b) receive empirical combination antibiotic therapy or monotherapy. Empirical antibiotic therapy was initiated in all patients until cultur...

Ventilator-associated pneumonia (VAP) is a serious complication related to mechanical ventilation in the neonatal period. However, lack of a specific definition and difficulties obtaining noncontaminated samples of the lower respiratory airway render microbiological diagnosis and etiological treatment extremely difficult. Thus far, only few studies have approached VAP using accepted Centers for...
