Bacterial Crown of Grapes with Particular Devote on the Seedling Material

The production of healthy bedding material of grapes are extremely complex and responsible work, which needs high qualifications and knowledge from different aspects. Bedding material can transmit many diseases and pests, and has a bad influence in susceptibility, developing and fruitfulness in grapes. The some problem makes bacterial crown gall indicated by Agrobacterium tumefaciens. The bacterium with its products, affect the meristem tissues and develop tumor tissues. So, the bacterium has an indirect influence perturbing leaf vein and root system. Diseased grafts have got a slow advancement and soon they decay

First Appearance of White Mould on Sunflower Caused by Sclerotinia Minor in the Republic of Macedonia

Sclerottnia spp. a very destructive fungus causing "white mould" became one of the biggest problems in sunflower breeding in the Republic of Macedo­nia in 2010. Field monitoring in the region of Bitola show very high infection of around 20-30%. Two types of symptoms where observed during the field mon­itoring. First symptoms were observed on the leaves of the Infected plants in the form of wilting, prior to flowering stage. The most characteristic symptoms were observed. at the lower part of the stem in the form of a stem cancer. Big variable sclerotia in size and shape were observed inside the stem. The appear­ence of white mycelium on the infected lower parts of the plant was often observed during the wet weather. Other infected plants showed different symp­toms. The stem was longer and thinner than in uninfected plants and the pit was very small around 9 cm. Sclerotia observed inside the stem were not big­ ger than 2.5 mm. In vitro investigations confirmed the presence of ascomycetes Sclerotinia sclerattorum (Lib.) de Bary and Sclerotinia minor Jagger, for the first time In the Republic of Macedonia. In vitra Investigation of antifungal abillty of Pseudomonas mediterranea Cattara et al., 2002 against S. sclerottorum and S.minor showed that it can be a possible antifungal agent against these ascomycetes

Molecular identification of a phytoplasma infecting grapevine in the Republic of Macedonia

Phytoplasmas from the ribosomal subgroup 16SrXII-A (stolbur) were identified by PCR and RFLP analyses of 16S rRNA gene and elongation factor-Tu phytoplasma gene (tuf) in symptomatic grapevines from the Veles and Skopje areas in Macedonia. Two methods were used for nucleic acid extraction. Amplification and RFLP results of 16S rDNA were not influenced by the method used, but RFLP patterns of tuf gene revealed additional bands if a less time consuming method was applied. The possible origin of these bands is discussed. This is the first report of the presence of the stolbur phytoplasma in cvs Chardonnay and Vranac in Macedonia.

Multilocus genotyping reveals new molecular markers for differentiating distinct genetic lineages among “candidatus phytoplasma solani” strains associated with grapevine bois noir

Grapevine Bois noir (BN) is associated with infection by “Candidatus Phytoplasma solani” (CaPsol). In this study, an array of CaPsol strains was identified from 142 symptomatic grapevines in vineyards of northern, central, and southern Italy and North Macedonia. Molecular typing of the CaPsol strains was carried out by analysis of genes encoding 16S rRNA and translation elongation factor EF-Tu, as well as eight other previously uncharacterized genomic fragments. Strains of tuf-type a and b were found to be differentially distributed in the examined geographic regions in correlation with the prevalence of nettle and bindweed. Two sequence variants were identified in each of the four genomic segments harboring hlyC, cbiQ-glyA, trxA-truB-rsuA, and rplS-tyrS-csdB, respectively. Fifteen CaPsol lineages were identified based on distinct combinations of sequence variations within these genetic loci. Each CaPsol lineage exhibited a unique collective restriction fragment length polymorphism (RFLP) pattern and differed from each other in geographic distribution, probably in relation to the diverse ecological complexity of vineyards and their surroundings. This RFLP-based typing method could be a useful tool for investigating the ecology of CaPsol and the epidemiology of its associated diseases. Phylogenetic analyses highlighted that the sequence variants of the gene hlyC, which encodes a hemolysin III-like protein, separated into two clusters consistent with the separation of two distinct lineages on the basis of tufB gene sequences. Alignments of deduced full protein sequences of elongation factor-Tu (tufB gene) and hemolysin III-like protein (hlyC gene) revealed the presence of critical amino acid substitutions distinguishing CaPsol strains of tuf-type a and b. Findings from the present study provide new insights into the genetic diversity and ecology of CaPsol populations in vineyards

International Nosocomial Infection Control Consortium (INICC) report, data summary for 2003-2008, issued June 2009

Q3Artículo original95-106We report the results of the International Infection Control Consortium (INICC) surveillance study from January 2003 throughDecember 2008 in 173 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study, using Centersfor Disease Control and Prevention (CDC) US National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infec-tion Surveillance system [NNIS]) definitions for device-associated health care-associated infection, we collected prospective datafrom 155,358 patients hospitalized in the consortium’s hospital ICUs for an aggregate of 923,624 days. Although device utilizationin the developing countries’ ICUs was remarkably similar to that reported from US ICUs in the CDC’s NHSN, rates of device-asso-ciated nosocomial infection were markedly higher in the ICUs of the INICC hospitals: the pooled rate of central venous catheter(CVC)-associated bloodstream infections (BSI) in the INICC ICUs, 7.6 per 1000 CVC-days, is nearly 3-fold higher than the 2.0 per1000 CVC-days reported from comparable US ICUs, and the overall rate of ventilator-associated pneumonia (VAP) was also farhigher, 13.6 versus 3.3 per 1000 ventilator-days, respectively, as was the rate of catheter-associated urinary tract infection (CAUTI),6.3 versus 3.3 per 1000 catheter-days, respectively. Most strikingly, the frequencies of resistance ofStaphylococcus aureusisolatesto methicillin (MRSA) (84.1% vs 56.8%, respectively),Klebsiella pneumoniaeto ceftazidime or ceftriaxone (76.1% vs 27.1%, respec-tively),Acinetobacter baumanniito imipenem (46.3% vs 29.2%, respectively), andPseudomonas aeruginosato piperacillin (78.0%vs 20.2%, respectively) were also far higher in the consortium’s ICUs, and the crude unadjusted excess mortalities of device-relatedinfections ranged from 23.6% (CVC-associated bloodstream infections) to 29.3% (VAP)
