Both in-vitro and in-vivo studies were carried out to evaluate the antimicrobial activities and potency of this combination. A total of one hundred and eighty day-old chicks were randomly allotted to 6 groups i.e. G1 (negative control), G2 (positive control), G3 (standard antibiotic neomycin only), SN-1 (Serratiopeptidase @40g/L+Neomycin@10mg/L), SN-2 (Serratiopeptidase @50mg/L+ Neomycin @20mg/L), and SN-3 (Serratiopeptidase @ 60mg/L+ Neomycin @30mg/L). Each group consisted of thirty birds with 5 replicates (6 birds/ replicate). On day 21, fresh inocula of E. coli (1x10 9 cfu ) were orally administered to all the groups except negative control. The results revealed that birds in SN-3 group showed significantly larger zone of inhibition, increased feed intake, weight gain and improved feed conversion ratio compared to standard and control groups. Moreover, reduced (p<0.05) mortality and morbidity index was found in SN-3 group among all the treated groups. It was concluded, that use of serratiopeptidase combination with neomycin has better impact on broiler chickens to enhance the antimicrobial effect of Neomycin against E. coli infection and to enhance production parameters.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67570310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different physicochemical methods have been used to reduce these pollutants but all have their own limitations including production of secondary pollutants. The current study was designed to show the effect of cellulolytic and sulphate-reducing bacterial species in the form of a co-culture to treat an in-vitro prepared sulphate-rich wastewater while employing various agro-industrial organic waste as economical growth substrates. A combination of sulphate-reducing and cellulolytic bacteria in a ratio of 1:1 (v/v) was proved to be efficient for the reduction of sulphate in controlled as well as in the experimental conditions. The implicated microbial co-culture reduced 96 and 93 % of the added sulphate (5 gL −1 ) while using rice straw and animal manure, respectively in a 60-day trial of anaerobic incubation. Mixture of industrial and agricultural waste reduced about 90 % of the total added sulphate. A trend of decrease in pH with time was observed in all the incubated cultures. Our findings will be helpful for devising sustainable waste management strategies.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67571744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Down regulation or inactivation of HOXA5 expression occurs in a variety of malignant tumors such as oral cancer (OC) and breast cancer. The promoter region of HOXA5 gene is often methylated, and it is of great value to explore the relationship between its methylation status and gene expression level. The objective of this study was to explore the promoter methylation status of tumor suppressor gene HOXA5 in OC. HOXA5 mRNA expression was detected by RT-PCR. OC CAL-27, H357, and HSC-3 cells were treated with different concentrations of 5-aza-deoxyeytidine to analyze the inhibitory effect of 5-aza-deoxyeytidine on methylation. The methylation status of HOXA5 gene promoter was closely related to OC. 5Aza-CdR could induce the expression of HOXA5 mRNA in OC cells, promote cell apoptosis, and inhibit the growth and spread of tumor cells. The promoter region of HOXA5 gene is hypermethylated in OC. It was concluded that 5Aza-CdR can inhibit the activity of DNA methyltransferase, restore the expression of HOXA5 gene, and inhibit the proliferation and spread of cancer cells.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135262975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
