N M Manjunath, Preema Melani Pinto
Mucormycosis is a rare but often fatal fungal infection caused by a group of fungus known as the Mucorales. This fungus can cause varieties of infections in human beings, especially in an immunocompromised condition. According to various studies, the mortality rate ranges from 10% to 100% depending on the location and site of infection accompanied by underlying diseases. Rhinomaxillary involvement is the most common form of mucormycosis predominantly occurring in patients with uncontrolled diabetes. Necrosis of the maxilla in patients with rhinomaxillary form is less evident as the maxilla is richly vascular, but in case of immunocompromised status, it becomes a common clinical finding...

Flies play an important role as vectors in the transmission of antimicrobial-resistant bacteria (ARB) and are hypothesized to transfer ARB between internal and external livestock housing areas. The aim of this study was to understand the role that flies may play in the maintenance of ARB in the farm environment. We first evaluated the fate of ingested antimicrobial-resistant Escherichia coli harboring a plasmid containing antimicrobial-resistance genes (ARGs) throughout the housefly (Musca domestica) life cycle, from adult to the subsequent F1 generation...

Purpose: The aim of this study is to improve the anti-biofilm activity of antibiotics. We hypothesized that the antimicrobial peptide (AMP) complex of the host's immune system can be used for this purpose and examined the assumption on model biofilms. Methods: FLIP7, the AMP complex of the blowfly Calliphora vicina containing a combination of defensins, cecropins, diptericins and proline-rich peptides was isolated from the hemolymph of bacteria-challenged maggots...

High temperatures were investigated to manage blueberry maggot (Rhagoletis mendax Curran; Diptera: Tephritidae) in field and postharvest situations. To estimate lethal combinations of high temperatures/duration of exposure, blueberry maggot pupae were immersed in water at various temperatures during either 1 or 30 s in the laboratory. Treatments such as 70°C (1 s) or 55°C (30 s) caused 100% mortality of blueberry maggot pupae. In a lowbush blueberry field, soil temperatures at 0, 1, 2, 3, 4, and 5 cm depth were measured with thermocouples following the passage of a flamethrower attached to a tractor in the fall...

Kondwani R Msangosoko, Mark A Boetel
The sugarbeet root maggot, Tetanops myopaeformis Röder (Diptera: Ulidiidae), is native to North America. However, its primary crop host, sugarbeet, Beta vulgaris L., was introduced to the continent from Europe in the late 19th century. This field and greenhouse research was conducted to compare the relative attractiveness of eight cultivated and wild plant species for oviposition by T. myopaeformis, and the suitability of these potential host plants for larval development to elucidate the potential native and current host range of this pest...

Nathan J Butterworth, Phillip G Byrne, Paul A Keller, James F Wallman
Cuticular hydrocarbons (CHCs) play an important role as contact pheromones in insects, particularly in flies. However, for many fly taxa our understanding of the importance of CHCs in sexual communication is limited. Within the family Calliphoridae (blowflies), sex-specific differences in CHCs have been reported for several species, but there is no evidence that CHCs facilitate sexual behavior. In order to elucidate the function of CHCs in Calliphoridae, studies combining behavioral and chemical analyses are required...

Myiasis is the infestation of humans with dipterous larvae. Traditionally, myiasis was thought to affect individuals living in tropical regions, however, several cases in temperate zones have been reported. We encountered two patients with histories of malignancies that presented with complaints of myiasis, in Chicago, in the spring and summer of 2016. The first patient, a 54-year-old female with a history of breast cancer, presented with complaints of maggots infesting her postsurgical chest wounds. She was diagnosed with sepsis, cellulitis, and wound myiasis...

Nivedita Page, Vivek Nirabhawane
Introduction: Cancer wounds need regular dressing; else they develop infection, foul odor, and in extreme cases, maggots. Patients resist dressing due to the severe incidental pain during dressing. Intranasal ketamine was tried as an analgesic to reduce this incidental pain. Materials and Methods: Twenty patients with wounds requiring regular dressing were selected; these patients had a basal pain score of 4/10 and incidental pain score of 7/10 during four consecutive dressings...

Necrophagous Calliphoridae breed in vertebrate carrion. Their larvae aggregate and form large masses of individuals. These aggregated larvae can reach adulthood faster than scattered larvae, increasing their chances of survival. Furthermore, the gathering of larvae of different species suggests possible interspecific aggregation vectors. In this context, the effect of larval ground-left cues on larvae of Calliphora vomitoria and Lucilia sericata was studied. We used video tracking to follow larvae placed in binary choice tests...

An outbreak of botulism occurred over a two-month period beginning July 20, 2016. In all, 697 wild birds were found paralyzed or dead at the Namdong reservoir and 11 Gong-gu. Using a mouse bioassay, type C botulinum toxin was identified in the bird serum, liquid cultures of soil samples, and maggot extracts. To minimize further infection of wild birds, we opened the floodgates of the Namdong reservoir adjacent to the Yellow Sea; this decreased the water temperature and the nutrient load such as nitrogen and phosphorus...

Cutaneous ulcers tend to become chronic and have a profound impact on quality of life. These wounds may become infected and lead to greater morbidity and even mortality. In the past, larvae (ie, maggots) of certain common flies (Lucilia sericata and Lucilia cuprina) were considered useful in ulcer management because they only remove necrotic tissue while promoting healthy tissue in the wound bed, thus helping wounds heal faster. Recently, maggots from several other fly species (Calliphora vicina, Calliphora vomitoria, Phormia regina, Chrysomya albiceps, Sarcophaga carnaria, and Hermetia illucens) have been shown in vitro to possess characteristics (ie, debridement efficacy and putative antimicrobial potentialities) that make them suitable candidates for possible use in clinical practice...

We report a case of severe upper extremity complex regional pain syndrome type 1 (CRPS-1) and neurogenic edema that ultimately led to a medically necessary below-elbow amputation. The patient presented with a history of remote bilateral carpal tunnel release complicated by debilitating and recalcitrant bilateral CRPS-1. Following years of severe neurogenic edema of the left upper extremity, the patient had full-thickness skin sloughing on the dorsum of her hand due to massive edema. This subsequently led to maggot infestation of the soft tissues of the left hand ultimately necessitating amputation...

Maggot extract (ME) accelerates rat skin wound healing, however its effect on cell maintenance in wound tissues remains unclear. B‑cell lymphoma (Bcl) 2‑associated athanogene (BAG)3 inhibits apoptosis and promotes autophagy by associating with Bcl‑2 or Beclin 1. Bcl‑2, the downstream effector of signal transducer and activator of transcription 3 signaling, is enhanced in ME‑treated wound tissues, which may reinforce the Bcl‑2 anti‑apoptotic activity and/or cooperate with Beclin 1 to regulate autophagy during wound healing...

OBJECTIVE: Maggot debridement therapy (MDT) has proved an efficient and reliable approach for wound healing. We explain the use of maggots with a stepwise procedure for conducting MDT in a patient with severe and large electrical wounds. METHOD: We captured the flies of Lucilia sericata from the natural environment, Alborz, Iran, and reared them in netted cages. The eggs obtained from the flies were disinfected with chloramine, and then were incubated on culture medium...

Ignatzschineria indica is a Gram-negative bacterium that is commonly associated with the larvae of flesh flies. I. indica is difficult to isolate in routine laboratory procedures but has been associated with neglected wounds infested with maggots, fever, elevated white blood count and C-reactive protein, and polymicrobial culture results. Other specific hematological/immunological changes are not known. We present a case of I. indica bacteremia and polymicrobial osteomyelitis resulting from infected decubitus ulcers...

Lucilia cuprina (Wiedemann; Diptera: Calliphoridae) is a facultative ecto-parasitic fly, distributed throughout the temperate and subtropical regions of the world. This blow fly species is of medical, veterinary, and forensic importance due to it being used in maggot debridement therapy (MDT), a causative agent of myiasis, and a decomposer of vertebrate carrion. The current study examined the combined effects of temperature and tissue type on the development of L. cuprina. Specimens were reared on three tissue types; swine muscle, swine liver, and bovine muscle at 20°C, 25°C, 27°C, and 38°C...

In this study, soft hydrogel crawlers with remote magnetic-responsive motility in confined spaces have been developed. Inspired by the motion of maggots, the hydrogel crawlers can reversibly contract and elongate their body controlled by repeatedly switching on/off an alternating magnetic field. Based on the cyclic deformation, the hydrogel crawlers can move peristaltically in a confined space that is coated with asymmetric micro-patterns. The dependence of the hydrogel motility on the pattern structures and lubrication is characterized using experimental measurements...

The onion maggot, Delia antiqua , is a worldwide subterranean pest and can enter diapause during the summer and winter seasons. The molecular regulation of the ontogenesis transition remains largely unknown. Here we used high-throughput RNA sequencing to identify candidate genes and processes linked to summer diapause (SD) induction by comparing the transcriptome differences between the most sensitive larval developmental stage of SD and nondiapause (ND). Nine pairwise comparisons were performed, and significantly differentially regulated transcripts were identified...
