“…Escherichia coli) bacteria. 22 It is possible that the presence of antibacterial peptides in M. domestica larvae could be influential in the lack of retention of C. difficile through metamorphosis and although yet to be discovered in M. domestica, some insects (the Korean dung beetle, Copris tripartitus) do possess antimicrobial peptides (coprisin) with activity against vegetative cells of C. difficile. 23 …”

“…Adult blow flies oviposit in natural body orifices. Staphylococci are abundant in the oral cavity, upper respiratory tract and genital regions of the human body [28], with Staphylococcus aureus being found in nasal passages of 30% of the human population [29] and Escherichia coli is commonly found in the rectum area [28]. Both bacterial species have also been isolated from corpses during the first 72 hours after death [30][31].…”

Colonisation times and development rates of specific blow fly species are used to estimate the minimum Post Mortem Interval (mPMI). The presence or absence of bacteria on a corpse can potentially affect the development and survival of blow fly larvae. Therefore an understanding of microbial-insect interactions is important for improving the interpretation of mPMI estimations. In this study, the effect of two bacteria (Escherichia coli and Staphylococcus aureus) on the growth rate and survival of three forensically important blow fly species (Lucilia sericata, Calliphora vicina and Calliphora vomitoria) was investigated.Sterile larvae were raised in a controlled environment (16:8h day: night light cycle, 23:21˚C day: night temperature cycle and a constant 35% relative humidity) on four artificial diets prepared with 100µl of 10 5 CFU bacterial solutions as follows: 1) E. coli 2) S. aureus 3) a 50:50 E. coli: S. aureus mix and 4) a sterile bacteria-free control diet. Daily measurements (length, width and weight) were taken from first instar larvae through to the emergence of adult flies. Survival rates were also determined at pupation and adult emergence. Results indicate that bacteria were not essential for the development of any of the blow fly species.However, larval growth rates were affected by bacterial diet, with effects differing between blow fly species. Peak larval weights also varied according to species-diet combination; C.vomitoria had the largest weight on E. coli and mixed diets, C. vicina had the largest weight on S. aureus diets, and treatment had no significant effect on the peak larval weight of L.sericata. These results indicate the potential for the bacteria that larvae are exposed to during development on a corpse to alter both developmental rates and larval weight in some blow fly species.

“…Groups around the world have invested in research on new antibiotics and on different modes of action to fight pathogenic bacteria in humans (Bexfield et al, 2008;Rasko et al, 2008;Nigam et al, 2006;Tang et al, 2009;Van Den Berg et al, 2008;Bexfield et al, 2004); however, the possibility of applying such solutions in animals is very remote, and therefore, livestock production relies on the improvement of health conditions to obtain better results (Tabes, 2008).…”

The use of probiotics in animal and human feeding has been a subject of increasing interest both for the academia and the industry, mostly due to their potential positive effects on health and profitability. However, the knowledge on the composition of bacterial gastrointestinal communities in humans and animals, as well as its respective nutritional requirements, is far from being elucidated. Due to the ban of the use of antibiotic growth promoters in animal feeds, there has been an increasing interest on the utilization of probiotics to improve animal intestinal health under commercial settings. However, the possibility of horizontal transference of antibiotic-resistant genes between probiotic bacteria and pathogenic species has become a concern of poultry farmers and consumers around the world. Innovative ideas have emerged, such as the addition of essential oils, spices, and other plant extracts to feeds of monogastric animals to promote intestinal health. These natural compounds are considered ecologically adequate and safe for feeding purposes. This new reality will probably change the direction of research and of the use of additives in poultry production.
