Mold Flora of Traditional Cheeses Produced in Turkey
2016
Musa Yalman | Seda Özdikmenli Tepeli | Nükhet Nilüfer Demirel Zorba
In our country, there are many cheese types that are produced traditionally. Cheeses which produced from cows, sheep and goat milk that matured with spontaneous growth of molds present in livestock skins, pots and similar environments are among them. They are produced traditionally in Mediterrian, Central and Eastern Anatolia regions. Molds that grow spontaneously in cheeses could create public health risk because of their secondary metabolites. Penicillium spp. are the most isolated mold from these cheeses and Penicillium roqueforti is determined as the dominant species. Furthermore, Aspergillus, Alternaria, Mucor, Geotrichum, Cladosporium species have been isolated. It is very important to control the ripening conditions and starter strain selection since some strains were reported as mycotoxin producers. In this review, it has been tried to give general information about traditional production of mold-ripened cheese in Turkey and the mold flora found in traditional cheeses. In addition, public health risk of these cheeses is reported.

2016
Sangeeta Yadav | Arun Kumar Barholia
Thirty five genotypes of coriander (Coriandrum sativum L.) were tested in four artificially created environments to judge their stability in performance of seed yield. The differences among genotypes and environments were significant for seed yield. Stability parameters varied considerably among the tested genotypes in all the methods used. The variation in result in different methods was due to non-fulfillment of assumption of different models. However, AMMI analysis provides the information on main effects as well as interaction effects and depiction of PCA score gives better understanding of the pattern of genotype – environment interaction. The sum of squares due to PCAs was also used for the computation of AMMI stability values for better understanding of the adaptability behavior of genotypes hence, additive main effects and multiplicative interaction (AMMI) model was most appropriate for the analysis of G x E interactions for seed yield in coriander. Genotypes RVC 15, RVC 19, RVC 22, RVC 25 and Panipat local showed wider adaptability while, Simpo S 33 exhibited specific adaptability to favourable conditions of high fertility. These genotypes could be utilized in breeding programmers to transfer the adaptability genes into high yielding genetic back ground of coriander.

Tülay Çimrin | Murat Demirel
This experiment was designed to investigate the effects of antibiotic, vitamin E and rosemary essential oils in various doses on some blood parameters, beneficial and harmful microorganisms in instentine jejunum microflora of lying hens. The experiment was conducted according to random parcel experiment design. A total of 240 Bovans genotype and 32 weeks aged were equally divided into 6 groups (8 hens in each group with 5 replicates). While the control group was fed with basal diet the treatment groups were supplemented with 500 mg/kg antibiotics; 200 mg/kg vitamin E; 100, 200, and 300 mg/kg REO to basal diet for 90 consecutive days. The result showed that there were no effects of all additions to basal diets on examined blood parameters. Antibiotic and all rosemary essential oils doses to basal diet affected the instentine jejunum bacteria content by decreasing probable coliforms, faecal coliforms, Escherichia coli (E. coli) and Clostridium perfringens (Cl. perfringens) bacteria level significantly. While a 100 mg/kg rosemary essential oils dose was of the same influence with antibiotic (500 mg/kg) on all bacteria species, 200 and 300 mg/kg doses applications were more effective on E. coli compare to antibiotics. 300 mg/kg doses applications dose was more effective on probable faecal coliforms than antibiotics. As conclusion, the results shows the rosemary essential oils has the high antimicrobial effect on some pathogenic bacterias and could be used in laying hen for feed addition.

Sancar Bulut
Insufficient capital an technical sources of agricultural enterprises, old-ages and low educational levels of population dealing with agricultural activities, lack of technical stuff and resultant insufficiencies of extension services and adverse climate conditions experienced time to time all negatively influence cereal farming and productivity levels in Sivas province. Large fallow lands over monoculture cereal lands, insufficient certified seed utilization, improper soil tillage and seedbed preparation practices, delay of winter sowings or high summer sowing rates (especially in barley), insufficient chemical fertilizer uses because of high fertilizer costs, lack of scientific research on cereals and untimely weed control practices also significantly limit cereal yields. All these aforementioned theoretical and economical deficiencies should be eliminated to have high yield levels in cereal farming of Sivas province.

Olusegun Ayodele Olaoye
Five strains of Lactococcus, including L. garviae K2, L. piscium SU4, L. lactis subsp. cremoris E22, L. plantarum L7 and L. lactis subsp. hordinae E91 were screened for production of antimicrobial agents. The strains were also analysed for antimicrobial activities against spoilage and pathogenic organisms, including Staphylococcus aureus, Salmonella Typhimurium, Escherichia coli, Yersinia enterocolitica, Pseudomonas aeruginosa, Klebsiella pneumoniae, Listeria monocytogenes, Bacillus cereus and Pseudomonas fluorescens. Result revealed that L. piscium SU4, L. plantarum L7 and L. lactis subsp. cremoris E22 had lactic acid production (g/107 colony forming units, CFU) of 7.23, 7.20 and 7.19. The value of 6.83 recorded as lactic acid produced by L. garviae K2 was significantly different from those obtained for others. The highest acetic acid production (3.55 g/107 CFU) was recorded for L. garviae K2 while L. piscium SU4 had the lowest (2.99 g/107 CFU). L. lactis subsp. hordinae E91 had diacetyl production of 71.99 (µg/107 CFU), which was higher than those recorded for other Lactococcus strains. Test for antimicrobial activities showed that Escherichia coli NCTC 86, Yersinia enterocolitica NCTC 10460, Pseudomonas aeruginosa NCIMB 10848, Bacillus cereus NCTC 21113 and Pseudomonas flourescens recorded higher susceptibilities to the antimicrobial action of the Lactococcus strains than others; zones of inhibition of 5 mm and above were recorded for the indicator organisms compared to lower values (

Zia ud Din | Parvez Iqbal Paracha | Zahoor ul Haq | Zahoor Ahmad | Zara Khan | Muhammad Asif
This follow-up study was carried out to investigate association of wheat productivity with the nutritional status of farmers in an agricultural area of North West Pakistan. A total of 1200 small scale farmers were randomly recruited and screened for nutrition status. Total of 226 farmers were found malnourished. An equal number of well-nourished farmers were randomly selected; detailed data on wheat yield and relevant confounding factors were collected interviewing groups. Multivariate linear regression analysis was performed to identify factors in relation to wheat yield. Comparing to well-nourished, malnourished farmers were more likely to report less wheat yield. Agricultural predictors that independently and significantly explained variation in wheat production included crop rotation, sowing time, and per acre agricultural inputs. Farmers' nutritional status; and dietary patterns further increased variance in wheat yield. The study findings reaffirmed the importance of farmers' nutritional status in predicting wheat yield.

2016
Sayed Mohammad Naim Khalid
Agricultural development is now expected to proceed in a way that maximizes opportunities to improve health and nutrition. Accordingly, the term “nutrition-education-agriculture linkages” describes the set of relationships that shows the mutual dependence of nutrition, education and agriculture. Changes in nutrition or education status are expected to affect agricultural production; conversely changes in the agricultural sector can have significant effects on individual health and nutritional status. Professionals in are trained in nutrition or agriculture, but very few will be trained in both. It is therefore difficult to begin discussions on nutrition-focused agricultural programs and policies. How do we begin to identify these linked outcomes? And how do we begin to think about ways to impact factors that are outside of our sector of expertise? This paper provides a simple framework for thinking critically about nutrition, education and agriculture linkages. The purpose is to help readers identify the linkages of greatest importance to their goals and to begin thinking about how to take steps toward integrating programs more effectively.

Salmonella is considered as a global problem ranking first among food borne diseases. All motile Salmonella of poultry origin are zoonotic and readily transmit to human via meat and eggs but reports on non - typhoidal Salmonella serovars circulating in layer chickens is very limited in South-East Asian countries including Bangladesh. Salmonella serovars isolated from apparently healthy chickens were characterized in the present study. Of 170 samples (cloacal swab 150 and feed 20) collected from commercial layer farms, motile Salmonella was isolated 4% (6/150) and 50% (10/20) respectively by cultural, biochemical, motility test and by detection of hisJ gene. About 5% (8/170) samples possessed serovar-specific gene fimA, suggesting that isolates were Salmonella enterica serovar Typhimurium. Antimicrobial susceptibility testing demonstrated that the isolated serovars were multidrug resistant. Therefore apparently healthy layer chickens harbour and transmit S. Typhimurium to the environment, although little is alarming since it has zoonotic significance and the isolates were resistant to commonly used first line of antibiotic in Salmonella infection.
