Forage yield and lodging traits in peas (Pisum sativum L.) with different leaf types

Two semi-leafless and four leafed pea (Pisum sativum L.) genotypes were evaluated for plant height, lodging scores, and forage yield in eight diverse locations with typical Mediterranean or Mediterranean-type climate in the 2001-2002 and 2002-2003 growing seasons. The genotypes used in this study were forage type with indeterminate growing habit. Significant differences among pea genotypes were found for all traits over years and locations. All interactions which related to G x E interaction showed significance (P>0.01) for all traits. The forage yield of the pea genotypes averaged 26605 kg ha(-1) and the highest yield was obtained from the leafed genotype Urunlu. Its forage yield reached to 35970 kg ha(-1) yield level at Samsun location

Genotype x nvironment interaction and stability analysis for dry matter and seed yield in field pea (Pisum sativum L.)

The objectives of this study were to evaluate dry matter (DM) yield and seed yield of six leafed and semi-leafless pea (Pisum sativum L.) genotypes, and to compare them for these traits. Evaluation of genotype x environment (G x E) interaction, stability and cluster analysis were also carried out at eight diverse locations with typical Mediterranean and Mediterranean-type climate during the 2001-2002 and 2002-2003 growing seasons. Significant differences were found among the pea genotypes for DM and seed yield on individual years and combined over years, and in all locations. All interactions which related to G x E interaction showed significance (P>0.001) for DM and seed yield. The highest yield (4789 kg ha(-1)) was obtained from the leafed genotype 'Urunlu'. However, stability analysis indicated that for DM yield, the leafed genotypes 'Golyazi' and 'Urunlu' should be grown in low yielding and high yielding environments, respectively. Cluster analysis, based on grouping locations, showed that P101 was the preferred variety in low yielding environments, and P98, in high yielding ones. It was suggested that the use of both stability and cluster analyses might give better results. Comparison of cluster and stability analyses showed that the stability analysis fails to recommend cultivars to different regions where yield potential showed significant differences. It seems, however, that cluster analysis could be a powerful tool to examine G x E interaction. If the number of environments was sufficient, a separate stability analysis could be run in each cluster

Antimicrobial Susceptibility of Enterococcus Species Collected from Clinical Specimens

Seventy isolates of enterococci with species identification were collected from clinical specimens between August 1996-June 1997 and antimicrobial susceptibility tests were performed. Using conventional tests, 67.2% of the isolates were identified as Enterococcus faecalis, 28.6% of the isolates as E. faecium and 2.8% of the isolates as E. gallinarum. Penicillin and ampicillin resistance were present in 21.4% of the isolates and there was no β-lactamase producer. High-level resistance to gentamicin and streptomycin were detected in 31.4% and 22.8% of the isolates, respectively. While there was no vancomycin and teicoplanin resistance in E. faecalis and E. faecium strains, E. gallinarum strains were moderately susceptible to vancomycin but susceptible to teicoplanin. Ciprofloxacin resistance was present in 20% of the isolates. Penicillin, ampicillin, ciprofloxacin and gentamicin resistance were significantly higher in E. faecium strains than that in E. faecalis strains (p 0.05)

In vitro Activity of Trovafloxacin Against Various Microorganisms

In vitro activity of a new fluoroquinolone, trovafloxacin, was tested against 512 aerobic microorganisms by agar dilution method. Methicillin-susceptible Staphylococcus aureus (MSSA), Escherichia coli, Proteus, Salmonella and Shigella species were isolated from patients hospitalized in various clinics. Klebsiella spp., Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) were mainly the isolates of intensive care units. Minimum inhibitory concentration 50 and 90 (MIC50/MIC90) values for methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA) were ≤ 0.03/0.06 µg/mL and 1/2 µg/mL, respectively. The same values for gram negative aerobic bacteria were as follows; Klebsiella spp. 0.12/4 µg/mL. P. aeruginosa 2/ ≥ 16 µg/mL, E. coli ≤ 0.03/0.25 µg/mL, Proteus spp. 0.12/0.25 µg/mL, Salmonella and Shigella spp. ≤ 0.03/ ≤ 0.03 µg/mL. Our results of the in vitro activity of trovafloxacin which will be used in our country in the near future are compared with those of other studies

Lyme Seropositivity in Healthy Persons and Some Disease Groups

In this study, we aimed to investigate the prevalence of antibodies specific to Lyme disease in healthy subjects and in defined patients in Ankara and suburban areas near Ankara in the years 1995 and 1996. One hundered and fifty four individuals comprised to the study: 54 patients with probable Lyme disease symptoms and/or signs, and admitted to the Ankara University Faculty of Medicine, ‹bn-i Sina Hospital, (patients group); 50 subjects (i.e. farmers) living at two different suburban areas near Ankara (group at risk); and 50 healthy subjects living at urban area (control group). To search the antibodies we used a commercial ELISA kit, (combined purified Borrelia burgdorferi-B31 strain cell lysate and the recombinant P39 protein, as antigen). The seropositivity was detected as 13% (7/54) at the patients group, 6% (3/50) at the risk group, and 4% (2/50) at the healthy control group. There was no statistically significant difference inbetween the groups for the seropositivity rates. Positive test results were detected in 40% of the patients with erythema migrans-like skin lesions, 20% of the patients with cardiac involvements, 14.3% of the patients with rheumatologic disorders, and 6.25% of the patients with neurologic disorders. As the result, this study yielded that probability of the exposure to the Lyme disease agent, B. burgdorferi, in our region was similar to the other investigations done previously in different regions of our country

The Antibiotic Usage Before and After a Nationwide Antibiotic Restriction Policy at a University Hospital

There is a growing concern on wisely use of antimicrobial agents. Some nationwide restrictions on antibiotic usage have been settled via a regulation released by Turkish government in February 2003. We conducted a study to assess the impact of this nationwide antibiotic restriction policy (NARP) at a university hospital. All hospitalized patients were visited on 18th February 2003 (before the regulation) and on 15th September 2003 (after the regulation). For each patient receiving antibiotic treatment, demographic data, diagnosis, results from microbiological specimens, details of antibiotic administration, indication for treatment or prophylaxis, dosage, dose frequency and administration route were recorded on individual forms. The appropriateness of antimicrobial treatments were assessed by two infectious disease specialists and infectious disease proffessors according to the local and international guidelines. On the first prevalence day and on the second prevalence day 20.8% of patients were receiving antimicrobial treatment. Before and after NARP, 36% and 29% of antimicrobial treatments were judged inappropriate, respectively (p= 0.131). There was not any difference between surgical and medical wards. The rate of antibiotic usage without any clinical indication was significantly decreased after NARP (p= 0.03). After NARP, 42% of the empirical treatments was begun after infectious disease consultation, while it was 14% (p< 0.001) before NARP. Fourty-four percent and 36% of antimicrobial regimens used for surgical prophylaxis was inappropriate before and after NARP, respectively (p= 0.39). The daily cost of inappropriate antibiotic usage was 2661 and 2187 dollars in February and September, respectively (p= 0.77). We conclude that, NARP has a good but unsatisfactory impact on antibiotic usage and cost. Other interventions should be implemented for an optimal outcome
