  • Abstract

    Simple sequence repeats (SSRs) may have propensity for mutations in coding DNA sequences (CDSs) that may help pathogens develop drug resistance, enhance virulence or pathogenicity. The present study investigates presence of SSRs in CDSs of 125 Mycoplasmas. Though few CDSs have repeats, tri- and hexa-nucleotide repeats are abundant but dinucleotides CG/GC are missing. CDSs of Mycoplasmas infecting respiratory system have repeat abundance. SSR sequence percentage in Felidae and Canidae blood pathogens differ significantly with others. Pathogens in humans have range of low to higher frequencies of SSRs. However, this disparity does not relate with tissue or organ infected. To study SSR distribution in CDSs associated with different functions, CDSs were grouped as: Lipoprotein, Metabolism, and Replication, Repair and Recombination”, “Restriction modification, Ribosome, Transcription, Translation, Transport and Virulence. Based on SSR sequence percentage in CDS classes; Mycoplasmas form two major clusters. Though these clusters are neither pathogen specific nor tissue/organs or host specific; most Mycoplasmas that infect Aves form the first cluster. Further, Virulence CDSs have abundance of repeats and form a distinct cluster from other CDS classes. Host or CDS class specific repeats found in this study may help investigators in developing markers for monitoring CDSs alterations in pathogens.

  • Abstract

    In Côte d’Ivoire, Macrobrachium vollenhovenii is a common shrimp species of lagoon area. Microscopical and Histological observations of this shrimp made with the naked eye, the photographic binocular magnifying glass and the light microscope highlighted some criteria for identifying the stages of the ovogenesis. The morphology of these shrimps corresponds to the general description of the Palaemonidae shrimp. The sexual maturity of females includes 5 stages, identifiable through internal criteria. During sexual maturity occurs the differentiation of the ovary during ovogenesis. The ovary presented as orange viscous mass appears in the females of the stage I as two adjoining lobes. At the stage III ovary increases and one notes at the stage IV hypertrophy of the ovary that spreads in the whole cephalothorax of the animal. The volum of the ovary decreases at the stage V. Investigations with light microscope after histological treatment allowed following the different stages of ovogenesis. The process of the ovogenesis comprises five stages in which ovogonia change successively in oocytes and in follicles and has a single layer of follicular cells, which disappears before the eggs laying. Follicles are transformed in a telolecithal egg. It then starts directly its embryonic development

  • Abstract

    En Côte d’Ivoire, Macrobrachium vollenhovenii est une espèce de crevette commune des secteurs lagunaires. Les observations macroscopiques et histologiques réalisées à l’oeil nu, à la loupe binoculaire photographique et au microscope optique ont permis de mettre en évidence quelques critères d’identification des étapes de l’ovogenèse. La morphologie de ces crevettes correspond à la description générale de la crevette Palaemonidae. L’analyse macroscopique interne a permis d’établir chez les femelles une échelle de maturité sexuelle qui comporte 5 stades. Au cours de cette maturité, s’effectue la différenciation de l’ovaire ou ovogenèse. L’ovaire qui se présente sous forme d’une masse visqueuse orange, apparaît chez les femelles du stade I sous forme de deux lobes contiguës. Au stade III, on note l'accroissement suivi de l’hypertrophie de l’ovaire au stade IV. L’ovaire se répand dans tout le céphalothorax chez les femelles gravides. On note une régression du volume au stade V. Suite au traitement histologique et l’observation au microscope optique, il ressort que le processus de l’ovogenèse comprend 5 étapes au cours desquelles les ovogonies se transforment successivement en ovocytes et en follicules entourés d’une seule couche de cellules folliculaires qui disparaît avant la ponte. Les follicules aboutissent à des oeufs télolécithes. Le développement embryonnaire se réalise à partir de cet oeuf

  • Abstract

    The white spot disease is highly contagious disease caused by white spot virus (WSSV). It is one of the most damaging viral diseases which causes high morbidity and mortality rates in commercially important edible crustaceans. This disease causes serious economic losses to the shrimp farming industry worldwide. This disease is not transmitted from infected shrimps or other crustaceans to human after their consumption as seafood products. However, little information is available in terms of the evaluation of the nutritive quality of edible muscles of infected organisms. So, the aim of the current study was, therefore, to estimate the concentrations of total protein percentage, level of essential amino acids, protein band electrophoresis and to detect DNA damage induced by WSSV in muscle cells of shrimps by using Comet Assay. In conclusion, regarding the results obtained in the present study in light of nutritional point of view of commercial shrimps, WSSV infection triggers alterations in biochemical components and strongly affects DNA of edible muscles of shrimps. In addition, WSSV is predicted to affect several basic cellular metabolic processes of shrimps. So, WSSV infected shrimps cannot be used as healthy food for human consumption.

  • Abstract

    Although by definition rare diseases are rare, taken all together they represent sufficient part of difficult to diagnose and treat cases. Diffuse alveolar hemorrhage is such rare yet serious medical emergency that often results in acute respiratory failure and death. The lung can be affected by systemic disease in different ways and every organ involvement or specific therapy could lead to life-threatening lung complications. We present two cases of patients with diffuse alveolar hemorrhage one in a pediatric department and the other one in ICU. Both cases despite respiratory symptoms had other organs involved. The specialists need to be aware that multisystem diseases may present initially with respiratory signs and symptoms. The correct diagnosis is crucial for prevention of life-threatening complications and for appropriate emergency treatment

  • Abstract

    Spices and herbs are widely consumed, due to their cooking benefits, unique flavors, colors, romas and medicinal importance. Unfortunately, they are liable to be heavily contaminated with toxigenic fungi with subsequent production of aflatoxins (AFs).Acute and chronic exposure to aflatoxin is onsidered a serious health risk problem. This study aimed to determine the level of AFs in some unpacked spices and herbs sold in local markets of Al Majmmah province. 45 unpacked spices and herbs samples including ginger,turmeric, cinnamon, cardamom, cumin, black pepper, chili pepper, cloves, laurel leaves and aniseed were collected randomly from local markets of Al Majmaah rovince, KSA from March to June 2017. The presence of AFs was determined by HPLC. AFs mainly, AFB1were detected in 13 samples. All results were below the limit of 10 ug/kg for total AFs. AFB1 levels were below 5ug/kg except for three turmeric samples.The levels of total AFs in all contaminated samples are in the permissible European limits. For AFB1, only three turmeric samples were beyond the European limits. Regular monitoring of unpacked spices is required.

  • Abstract

    There is no doubt that probiotics generate one of the most promising and dynamically developing segments of food industry. There are several factors supporting the inflow of functional products like the increasing consumer awareness in combination with new advances in various scientific domains. Functional foods have been developed virtually in all food categories, however their distribution over the segments of the market is not homogeneous and product preferences may vary between markets. The development and commerce of probiotic products is rather complex, expensive and risky, as special requirements should be answered. In the case of a successful product development attention should be paid both to consumer demands and technical conditions, furthermore, the legislation background should also not be neglected. Multi-national companies possess the adequate R&D activities, they know the economic potential due to their well-known products that give them the opportunity to introduce a brand new product to the market. Consumer acceptance, however, is determined by a number of factors such as primary health concerns, consumers’ familiarity with the ‘‘probiotics’’ concepts and with the functional ingredients, the nature of the carrier product, the manner of health effect communication, etc. The message of the health effect of a specific product should be transferred via credible media in a relatively simple way, so that it could be easily achieved by the consumers. As a rule, consumers seem to evaluate functional foods first and foremost as foods. Functional benefits may provide added value to consumers but cannot outweigh the sensory properties of foods. These products provide consumers a modern way to follow a healthy lifestyle, which differs from the conventionally healthy diet defined by nutrition experts. In general, the attitude both to functional foods and to their consumers is positive, so such a concept represents a sustainable trend in a multi-niche market.

  • Abstract

    The goal of the present research is to evaluate the ultrasonic efficiency in the extraction of Stevia glycosides, and compare its performance with the soxhlet traditional method. In this analysis, three extraction solvents were used: water, methanol and ethyl acetate. In addition, it was found that the developed extractions using water as a solvent presented the greatest performance for the soxhlet method, as well as for the ultrasonic method. In the case of soxhlet method using water as solvent, after seven hours extraction, a yield of 23.8% was obtained, with an extract weigh of 1.19 gr. On the other hand, the sample irradiated for 2 hours with ultrasound, showed a 24.6% yield, and 1.23 gr. of extract using water as solvent. Regarding the extracted glycosides, Rebaudioside A was the major compound, yielding 1.0 gr while Stevioside yield was 0.23 gr, both from 5 gr. of Stevia by ultrasonic extraction.

  • Abstract

    In this study, Random Amplified Polymorphic DNA (RAPD) markers were applied to analyse the genetic diversity of samples of the Misgurnus anguillicaudatus (Cantor, 1842), collected from six localities (A Luoi, Phong Dien, Phu Vang, Phu Loc, Quang Dien, and Huong Thuy) along Thua Thien Hue in Vietnam. The six primers used in RAPD analysis amplified 91 loci, 88 (96.70%) of which were polymorphic. The percentages of polymorphic loci observed in the six populations were: 61.54% (A Luoi), 58.24% (Phong Dien), 57.14% (Phu Vang), 39.56% (Phu Loc), 63.74% (Quang Dien), and 47.25% (Huong Thuy). Data for observed and effective number of alleles, Nei’s (1973) genetic diversity, and Shannon’s information index, for all the six populations were 1.55, 1.30, 0.18 and 0.27, respectively. The value for total genotype diversity among populations was 0.2239 while within populations diversity was found to be 0.1769. The mean coefficient of gene differentiation value and the estimate of gene flow across the populations were found as 0.2100 and 1.8812, respectively. The Nei (1978) measures of genetic distance and identity between pairs of loach populations indicate thatthe population originated from Phong Dien and Quang Dien has the highest genetic identity, while the fish originated from Phu Vang and A Luoi showed the greatest genetic distance.

  • Abstract

    Ivory Coast is part of the tropical zone with an interesting biodiversity. However, its essentially agriculture-based economy has led to the degradation and loss of forest favorable to several export crops. The pressure on these habitats, coupled with commercial hunting, affects both the functioning of ecosystems and the survival of living animals such as primates. These fragments of persistent forests in the Gbetitapea agroforestry system could be the refuge of the remaining fauna. It is therefore important to compile a biological inventory of forest fragments for the conservation of biodiversity and primates in particular. We aim to record the primate species and highlight their spatial distributions in these forest fragments. We conducted firstly, interviews of the populations bordering these forests to get a general idea of the species of monkeys in the space and the forests that shelter them. Then, field surveys were organized in the forests identified during the interview. From these investigation, 76 primates belonging to two species (Cercopithecus lowei and Cercopithecus petaurista). Three groups of Mona monkey and one group of white-nosed monkey were recorded in the sacred forest. In the forest fragment 1 only Cercopithecus petaurista was recorded. In forest fragment 2, one species (Cercopithecus lowei) has been also identified. With the exception of bordering areas, these species are encountered throughout the forests but are more concentrated in the center of forest fragments 1 and 2. To ensure sustainable management of these forests, all stakeholders, including scientists, foresters and local populations, should be involved.
