Molecular detection of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase-negative Staphylococcus (CoNS) in Iran

The incidence of methicillin resistance has risen among nosocomial isolates ofStaphylococcus aureus and coagulase negative staphylococci. The present study was carried out to investigate the prevalence of methicillin-resistant Staphylococcus aureus(MRSA) and methicillin-resistant coagulase negative staphylococci (MRCoNS) and to determine their antibiotic susceptibility pattern. A total of one hundred and...

Comparison of Agar screen and duplex-PCR methods in determination of methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from nasal carriage

Methicillin-resistant Staphylococcus aureus strains (MRSA) have become a serious health issue in engendering nosocomial infections. Due to the heterogeneity of this type of resistance, the conventional antibiotic susceptibility tests may fail to detect MRSA strains. The purpose of this research was to compare the phenotypic agar screen method with polymerase chain reaction (PCR) for detection of MRSA strains...

Pathogens in animal meal and the use of Salmex® in the elimination of Clostridium perfringens

The microbiological quality of the ingredients used in feed production is extremelyimportant for animal and public health because food can transmit pathogens. Chemical additives, such as Salmex®, may be used to control these pathogens, since manysporulated microorganisms are resistant to conventional heat treatment. For...

Identification of antifungal compound produced by Bacillus subtilis LB5 with ability to control anthracnose disease caused by Colletotrichum gloeosporioides

Bacillus subtilis strain LB5 showed inhibitory activity on conidial germination ofColletotrichum gloesporioides causal agent of mango and wax apple anthracnose disease. The antifungal metabolites produced by B. subtilis strain LB5 were highly stable to heat, pH ranging from 3 to 11, and ultraviolet (UV) light. Cell-free supernatant of LB5 culture broth was extracted by using n-butanol to give...

Evaluation of respiratory and echocardiography parameters in young female handball players

Long-term handball training has a significant impact in increasing cardiovascular resistance and the performance of ventilation on the respiratory system. In the present study, we investigated the effects of the long-term handball training of young female athletes on respiratory function and echocardiography (ECG) values. Thirty (30) girls (12.58±0.51 years) participated in the study. Some physical measurements,...

Evaluation of drought stress effects on germination and early growth of inbred lines of MO17 and B73

To study the effect of polyethylene glycol (PEG) stress on germination and early growth stages on two inbred lines of maize, experiment were laid out at seed laboratory, in Iran in 2012. This investigation was performed as factorial experiment under completely randomized design (CRD) with three replications. Inbred line factor consist of two inbred lines (MO17 and B73) and four levels of stress (0, -3, -6 and -9 bar)....

Genetic behavior of resistance to the beet cyst nematode (Heterodera schachtii Schm) in radish (Raphanus sativus L.)

The genetic nature of resistance to the beet cyst nematode (BCN) (Heterodera schachtiiSchm) in oil radish was investigated. A segregating population consisted of 245 F2individuals derived from self-pollinated single F1 plant of the radish cross ‘Pegletta X Siletta nova’ was used. Four oil radish populations and one Brassica napus cv. “Madora” as susceptible control were examined...

Oral immunization with silkworm pupae powder containing recombinant UreB of Helicobacter pylori affords prophylactic and therapeutic effects against Helicobacter pylori infection in mice

To study whether silkworm pupae powder (SPP) containing recombinant Helicobacter pylori urease B subunit (rUreB) could show immune prophylactic and therapeutic effect against H. pylori infection using a mouse model. The findings demonstrated that the mice were protected significantly from H. pylori infection based on the results of biopsy urease tests, biopsy bacterial...

Fermentative diversity of yeast selected for acidic musts

The objective of this paper was to assess the fermentation diversity of twoSaccharomyces cerevisiae strains and one Saccharomyces bayanus var. uvarumoriginated from fruit juice or pulp and previously classified as the ones with extended demalication ability. The fermentation profiles of yeast were assessed after 20 sequential subcultures (50 to 160 generations) under aerobic or semi-anaerobic...

Monitoring report on 341 cases of adverse reactions caused by antitumor drugs

This study aimed to summarize the main adverse reactions caused by antitumor drugs in China’s Henan Province and to provide reliable basis for strengthening drug administration in the future. This is a retrospective study conducted to analyze the monitoring of reports on 341 cases of adverse reactions caused by antitumor drugs collected from some AAA hospitals in Henan Province. Along with age increase and adverse...

Enrichment of anammox bacteria from mudflat sediments collected in Tokyo Bay

We established an enrichment culture of anammox bacteria by seeding a batch reactor with sediments from the Banzu mudflat in Tokyo Bay. The reactor was intermittently fed with an anammox substrate containing NH4Cl, NaNO2 and artificial seawater (3.03% salinity) for more than 800 days. An anammox enrichment culture capable of simultaneous reduction of approximately equivalent amounts of ammonium nitrogen and nitrite...

Biodegradation of some polycyclic aromatic hydrocarbons by Aspergillus terreus

In our search for new fungal isolates capable of degrading polycyclic aromatic hydrocarbons (PAHs) in soil, twenty one fungal isolates were recovered from Orman Garden, Wadi Degla Protectorate and benzene station soils. All tested fungi exhibited lignin peroxidase and manganese peroxidase activities in solid as well as in liquid cultures. However, laccase was detected in low amounts by some of the tested fungal...

Inhibitory effect of some spices powder and its oils on pathogenic microorganisms in liquid media

Addition of some spices to foods could not only impart flavor and pungent stimuli but also would provide antimicrobial property. In order to study the effect of spices (cinnamon, cloves and ginger), different concentrations (0, 0.4, 0.8, 1.2 and 1.6 g/L) in powder and in oil forms (individually and as a mixture) on some pathogenic microorganisms (Escherichia coli, Staphylococcus aureus, Bacillus cereus,...

Due to the rapid development observed in industries, environmental pollution became more and more critical. Lipase-producing strains played a key role in the enzymological remediation of polluted soils. Diversity of culturable lipase-producing bacteria in the southwest of China was studied with 198 samples collected from different points, along the transect from Tibetan Plateau-Ya An–Sichuan Basin. The...
