A total of 308 samples of 4 threatened species representing three order and four families were procured during April 2019 to March 2020 from 6 different sites (Ghazipur, Jaunpur, Sultanpur, Barabanki, Lucknow and Sitapur) of River Gomti. A minimum of 10 female individuals were selected to study the biometry, health and absolute fecundity. In the present study, the value of regression coefficient (b) obtained via length-weight relationship showed high heterogeneity where a fish showed isometric (b = 3), negative (b < 3) to positive (b > 3) allometric growth patterns. Fulton’s condition factor (K) was relatively found to be less than “1” which reflects the depletion in energy reserves except in B. lohachata collected from Jaunpur. The absolute fecundity varied from 1604 to 9049 and significantly different at the level of p < 0.001. In E. vacha, the “b” value ranges between 1.006–3.035, in O. pabda, the “b” value ranges between 2.628–3.469 and in C. chitala the “b” value was 2.426 and 3.255 and in B. lohachata the value of “b” was 3.180 which are considered to be the new record for fishdata base. The present study contributes the comparative description of growth pattern, well being and reproductive parameters of selected threatened fishes of River Gomti, India. The information gathered will be considered as baseline knowledge for future research to contemplate management strategies with reference to selected threatened fish species.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141195728","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}

In this study, we focused on the characterization of Gram-negative bacterial isolates obtained from Mauremys rivulata (Western Caspian turtle), Natrix natrix (Grass snake), Natrix tessellata (Dice snake) and Pelophylax bedriagae (Levantine frog) using cultural methods and determine some virulence factors (antibiotic resistance, VanA and TetM resistant genes, biofilm, siderophore and some enzymatic activities etc.). Multiple antibiotic resistance (MAR) and virulence index (VI) of each strain were also calculated. A total of 85 Gram-negative isolates exhibited varying levels of antibiotic resistance and the ability to produce one or more extracellular enzymes such as amylase, lecithinase, protease, lipase, hemolysis, siderophore, amino acid decarboxylase and DNase. Although the TetM has been identified in all 7 isolates, none of the isolates have shown the presence of the VanA gene. According to MAR and VI results, most of the isolates were found to be in the high threat group and these indexes were correlated with antibiotic resistance. The study data revealed that chemicals used in industry and agriculture both trigger environmental pollution and pose risk factors for wildlife.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141195808","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}
