They occured at different frequency ratios for each of oil-contaminated soil samples, the produced water, and the crude oil of the Al-Rafidiyah oil field (Basrah south of Iraq). Bacterial isolates were characterized and identified based on phenotypic properties and molecular techniques. Fourteen strains, belonging to three genera of Bacillus sp., Lysinibacillus sp. and Enterobacter sp., were isolated from oil-contaminated soil and nine strains, belonging to Bacillus sp., Lysinibacillus sp., Enterobacter sp. and Brevibacillus sp., were isolated from produced water. Five strains, belonging to two genera, Bacillus sp. and Pseudomonas sp., were isolated from crude oil. New twelve strains were recorded as new strains and deposited in GenBank include Bacillus cereus strain ASWISA1, Bacillus thuringiensis strain ASWISA2, Bacillus sonorensis strain ASWISA3, Bacillus cereus strain ASWISA4, Bacillus subtilis strain ASWISA5, Pseudomonas stutzeri strain ASWISA6, Bacillus subtilis strain ASWISA7, Bacillus cereus strain ASWISA8, Bacillus paramycoides strain ASWISA9, Bacillus paramycoides strain ASWISA10, Brevibacillus brevis strain ASWISA11, and Enterobacter cloacae strain ASWISA12.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"8 1","pages":"15-22"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76982734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a survey on intestinal parasites of chickens was carried out in the Souk Ahras region over a period of 6 months. The faeces of a total of 90 chickens collected from different farm types were examined by flotation to detect gastrointestinal parasites. The results obtained from these chickens showed that all the examined faeces were 100 % infected. The qualitative analysis showed a flocculation of helminths and protozoa’s oocytes across the taken chicken samples at different farms with different infection percentage. Broiler chicken reported infected with Ascaridia (50%); Heterakis (35%) and Eimeria (15%). The laying hen infected with Ascaridia, Heterakis and coccidial oocysts which represented by 33.33%, 33.33% and 33.34%, respectively. However, for the local chiken, Ascaridia: (40%) Heterakis (35%), Eimeria (15%), Syngamus (5%) and Capillaria (5%) were recorded. The high infection rate recorded in the study area suggested that an intensive poultry management system and regular chicken control should be held.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"34 1","pages":"47-52"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86304842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 62 species belonging to five taxonomic groups (Polychaeta, Mollusca, Crustacea, Echinodermata and Urochordata) were collected from benthic fauna at thirteen stations extending from Summer (2019) to Winter (2020) along the intertidal zone of the Suez Bay. Polychaeta accounted for 38.71% and 47.3% of the total number of species and individuals, respectively. While, Urochordata represented by one species and 50 indivi./m². In the Suez Bay, bacterial populations are present in the water with an annual density of 21598 cfu / 100ml with an average of 1661.4. At the same time they are present in the sediments with a numerical density of 16331 cfu / g with an average of 1256.23. Dissolved oxygen (DO), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) of tested samples ranged between 3.2 - 6.45 mgO2/l ; 0.995 -2.298 mg/l ; 2.298- 4.69 mg/l , respectively. This investigations revealed that, with the exception of the alien ; dominant and adherent rocks species (Spirobranchus kraussii and Brachidontes pharaonis), microbial components tend to increase their dominance, while bottom organisms were reduced during the entire study period. In addition ,this study indicated that there is a direct relationship with both salinity, dissolved oxygen and macro-benthic invertebrates, and at the same time there is an inverse relationship between them and bacterial counts, indicating thus a predominant effect of anthropogenic activities in the coastal area of Suez Bay.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"25 1","pages":"61-73"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90718740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
