The goal of this study is to look into the molecular occurrence, haemato-biochemical changes, and risk factors associated with the occurrence of BCoV infection in cattle calves at different dairy farms and small households in the district of Jhelum, Pakistan. From July 2020 to June 2021, 200 faecal samples were collected from newborn cattle calves exhibiting symptoms of diarrhoea and dysentery. S&C Biotech Bovine Coronavirus Antigen Rapid Test Kits were used to screen samples, which were then subjected to RT-PCR for molecular characterization. For the haemato-biochemical analysis, blood was taken from calves infected with BCoV. A questionnaire was used to collect information about the risk factors associated with the occurrence of BCoV infection. BCoV infection was found in 3.5% (7/200) of calves using diagnostic screening kits and 3.0% (6/200) of calves using RT-PCR. Breed, age, sex, vomiting, previous history of diarrhoea, body conditions, food type, colostrum feeding, deworming history, living environment, seasonal variation, and cohabitation with other animals were all assumed risk factors for BCoV infection ( p< 0.05). There was a significant ( p< 0.001) decrease in MCV (fl) and a significant ( p< 0.006) increase in TLC (1x10 3 /cm 3 ) on haematological analysis in BCoV-infected calves. TEC (1x10 6 /cm 3 ), WBC (1x10 6 /cm 3 ), RBC (1x10 6 /cm 3 ), and Hct% were significantly ( p< 0.05) higher. Similarly, infected calves had a non-significant ( p< 0.090) increase in K (mEq/L) and a significant ( p< 0.000) decrease in Na (mEq/L), Ca (mmol/L), Cu (mol/L), and Fe (mol/L) on biochemical analysis. It was concluded that the occurrence of BCoV infection was predisposed by assumed risk factors, and haemato-biochemical alterations were observed in BCoV infected calves.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":"32 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67568168","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}

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}
