Staphylococcus aureus and Staphylococcus epidermidis biofilms cause chronic infections due to their ability to form biofilms. The excretions/secretions of Lucilia sericata larvae (maggots) have effective activity for debridement and disruption of bacterial biofilms. In this paper, we demonstrate how chymotrypsin derived from maggot excretions/secretions disrupts protein-dependent bacterial biof...

Myiasis is the term used to describe infestations, both obligatory and accidental, in vertebrate animals and humans by dipteral larvae. The oral cavity is rarely affected by this infestation and the circumstances which can lead to oral myiasis include persistent mouth opening together with poor hygiene, or facial traumatism. We present a case of oral myiasis by larvae of Lucilia sericata, a spe...

The orientation of freely walking flies (female Lucilia cuprina) to lines and stripes in a circular arena is described. The following observations were made. 1. The flies walked straight towards a dark line using the frontal eye region, but a pale line on a dark background was only weakly attractive. 2. In bright conditions flies walked in a curved line towards a black-white edge, the path bein...

Blowflies, especially species belonging to the subfamily Luciliinae, are the first insects to lay eggs on corpses in Korea. Fast and accurate species identification has been a key task for forensic entomologists. Because conventional morphologic identification methods have many limitations with respect to forensic practice, molecular methods have been proposed to identify fly species of forensi...

Lucilia spp. also known as green bottle fly is well distributed, and it has forensic, medical veterinary importance. In the present study, sericata (Wiedemann, 1830) been recorded from Trans-Himalayan region of cold arid desert Kargil Ladakh. Distribution over a period April 2018 to March 2021 revealed that fairly distributed with maximum abundance being in midsummer July August, no activities ...

Background: The larvae of Lucilia sericata are efficiently and widely used in maggot therapy. The aim of this study was to investigate some environmental factors that influence the mass rearing of Lucilia sericata as the most suitable candidates for maggot therapy in Iran. Methods: This cross-sectional study was conducted in fli...

Sir, Antibiotic resistance of bacteria is a growing problem. Methicillin-resistant Staphylococcus aureus (MRSA) is a frequent nosocomial pathogen in many countries, with a high incidence in southern Europe, but with a lower incidence in Scandinavia (1). MRSA is most commonly isolated from ulcers and the respiratory tract (1).We report here a case of a leg ulcer carryingMRSA, which was treated w...

We describe and test a method for fitting noisy differential equation models to a time series of population counts, motivated by stage-structured models of insect and zooplankton populations. We consider semimechanistic models, in which the model structure is derived from knowledge of the life cycle, but the rate equations are estimated nonparametrically from the time-series data. The method in...

The New World screwworm fly, Cochliomyia hominivorax, and the Australian sheep blow fly, Lucilia cuprina, are major pests of livestock. The sterile insect technique was used to eradicate C. hominivorax from North and Central America. This involved area-wide releases of male and female flies that had been sterilized by radiation. Genetic systems have been developed for making 'male-only' strains...
