Flies succession, bacterial diversity, decompositional stages, a pig carcass


Investigations were conducted on the succession of forensic flies related to the stages of pig carcass decomposition, bacterial variety, and bacterial count associated with forensic flies' exterior body surfaces. Understanding the function of micro-organisms in the breakdown of carrion and how it pertains to post-mortem interval measurement depends on understanding that bacteria are the main decomposers. In place of human remains, pig-carcasses were used to monitor changes in the microbial community. This is a result of clinical investigations on humans frequently using pig corpses as animal models. Fresh and bloated phases attracted the biggest numbers and maximum diversity of fly species, according to the discovered bacterium species, which were decompositional stages were tallied. The initial fly species drawn to new and bloated pig carcasses were Muscidae, Calliphoridae, and Sarcophagidea. Bacterial species from Chrysomya albiceps, Piophila casei, Musca domestia, Sarcophage carrinaria, and Walfartia magnifica were isolated from their exterior body surfaces. The distribution of the presumed bacterial species, which vary in surface flies, includes Escherichia coli, Bacillus subtilis, Staphylococcus epidermidis, Pseudomonas aeruginosa, Staphylococcus aureus, Proteus mirabilis, and Staphylococcus hominis. The microbial population showed notable variance with respect to the time it took for decomposition.
