bacteria biotyping ( 1 , 2 , 3 , 4 ). Bacterial typing by MS is based on the fingerprinting of bacteria ribosomal proteins profiles using Matrix-Assisted Laser Desorption Ionization (MALDI) Mass Spectrometry (MS) through interrogation of a database of reference profiles ( 5 , 6 ). The technology was shown to be highly efficient after several inter-laboratory cross-validation( 7 ) and MALDI MS biotyping has become a conventional method for hospital routine biotyping due to its speed, simple handling, cost-effectiveness and high-throughput capabilities( 8 ). The U

Abstract

The genetic structure of crucian carps colonies in Ukrainian water bodies was defined by gene marking. The sexual structure and ploidy were investigated, the duration of spawners maturation, life-span, rate of growth and the linear growth of independent species and biotypes were defined. The comparative biological analysis showed that virtually all the researched crucian carps had low linear growth index and early maturation terms. Th e hybrid individuals of C. auratus-C. carassius during the first years of life were characterized by the high rate of growth which was most likely determined by the “hybrid power” which is kept by this biotype only within the starting phase of existence, after which the active growth is significantly reduced. Th e individual biological peculiarities of peculiar species and biotypes of crucian carps do not depend on their genetic nature but in most cases are defined by the external living conditions.

Abstract

This study was carried out to determine Salmonella contamination of food contact surfaces and processing water in meat, fish and poultry processing units in Sokoto State, Nigeria. A total of 200 swab (100 from abattoir and 100 from poultry and fish markets) and 60 processing water samples (30 from abattoir and 30 from poultry and fish markets) were collected between May to August 2015. Cultural isolation, bio-typing and sero-grouping using Salmonella Sero-Quick Group Kit was conducted to analyse the samples. Seventy-five (75/260, 28.8 %) of the total samples were positive to Salmonella by cultural isolation and bio-typing. Thirty (30/130; 23.1 %) of samples collected in abattoir and 45 (45/130; 34.6 %) of those collected from poultry and fish markets were positive for Salmonella respectively. Sero-groups D+Vi (Salmonella Typhi), B (Salmonella Paratyphi B, Salmonella Typhimurium) and C (Salmonella Paratyphi C, Salmonella Cholerae suis) were identified as the prevailing sero-groups in this study. Sero-group D+Vi has the highest prevalence (73.3 %; 55/75) from the positive bio-typing isolates. This study revealed the presence of contaminating and pathogenic Salmonella on food contact surfaces and processing water in the meat retail markets, indicating there is an urgent need to improve on the hygienic status of retail meat, poultry and fish markets.

Abstract

The paper proposes the improvement of the current bitter cherry assortment with new creations made at Iaşi, adapted to the specific conditions from the NE area of Romania. For the improvement of the bitter cherry assortment with new, productive, disease resistant cultivars with fruits of good quality, resistant to cracking with different maturation stages, in 1981 at Fruit Growing Research Station (F.G.R.S.) Iaşi - Romania has begun an action of selection and promoting of some valuable genotypes of bitter cherry (existent in the spontaneous flora or in plantations from the Iaşi county), which were being planted with cultivars and other genotypes from all around the country. Following the positive and gradual selection there were selected three biotypes of bitter cherry from which two of them have been approved as new cultivars in 1994, with the names „Amar Maxut”, respectively, „Amar Galata” and the biotype „Amar R5.P10” has been registered in 2013 at the State Institute for Variety Testing and Registration Bucharest to be approved as a new cultivar. All three bitter cherry genotypes correspond to the objectives of the main assortment breeding. They have a high productivity because the natural fertility index registered values between 36.5-63.7%, the trees have a reduced vigour, they present a good resistance to frost (1-9% affected buds) and to diseases (values of I% anthracnose, 1.1-2.8%). The fruits are high quality and the maturation stages are at the extremities of the cherries maturation season.
