Abstract
Ignatzschineria species have emerged only recently and few cases have been identified worldwide. It has been determined that maggots likely serve as the vector of transmission and the majority of cases described involved cutaneous myiasis. This article presents the first case of an Ignatzschineria species closely related to I. larvae/I. ureclastica causing bacteremia in North America. This isolated Ignatzschineria species is also unique in its broad antimicrobial resistance pattern to carbapenem antimicrobials, an uncommon finding among global Ignatzschineria isolates. Improving the ability to identify Ignatzschineria species is an important step to develop the necessary CLSI breakpoints and treatment guidelines. The paucity of information regarding Ignatzschineria species and the inability to accurately identify these organisms indicate the need for more research and improved identification techniques of this emerging pathogen.

Abstract
New World vultures, such as turkey vultures (Cathartes aura), are obligate scavengers with large geographic ranges. In a preliminary characterization of the turkey vulture (TV) gastrointestinal microbiome in Southern California, we identified 2 recently described emerging bacterial pathogens not previously known to be associated with this avian species. High-throughput sequencing of broad-range 16S rRNA gene amplicons revealed sequences from TV cloacal swabs that were related closest to Wohlfahrtiimonas chitiniclastica and Ignatzschineria species, both Gammaproteobacteria considered by the United States Centers for Disease Control and Prevention as emerging zoonotic pathogens. None of these bacterial sequence types have been previously identified from samples obtained from the turkey vulture gastrointestinal microbiome. With the use of bioinformatics workflows previously established by our research group, we designed specific and sensitive polymerase chain reaction primer sets that represent novel diagnostic assays for the genera Wohlfahrtiimonas and Ignatzschineria. These primer sets were validated by Sanger sequence confirmation from complex TV samples. Because the genera Wohlfahrtiimonas and Ignatzschineria are both known to have dipteran hosts, the molecular diagnostic tools we present here should be useful for better understanding the role of flies, vultures, and other scavengers in the ecology and epidemiology of the genera Wohlfahrtiimonas and Ignatzschineria from a One Health perspective.

Abstract
Bacteremia induced by wound myiasis is uncommon and therefore rarely suspected by clinicians when treating patients with neglected wounds. We present a case of Ignatzschineria larvae bacteremia as a complication of Lucilia sp. maggot wound myiasis in a young male migrant. This is the first reported human case of Ignatzschineria bacteremia in Slovenia and one of the 2 described in the literature where the fly larvae infesting the wounds of the patient with Ignatzschineria bacteremia were not only suspected to be Lucilia sp. but also entomologically identified.

Abstract
Ignatzschineria is a recently identified genus of bacteria that has been isolated from the digestive tract of multiple flies associated with decomposing tissue. Species within this genus are rarely implicated in human disease, and less than 10 cases worldwide have been documented in the literature. Although there have been several documented cases of Ignatzschineria indica bacteremia in the United States (with one previous case in Louisville, KY), this case represents the first documented case of Ignatzschineria ureiclastica/larvae bacteremia in the United States. The natural insect host of this bacteria, parasitic flies that are commonly found among sheep and other livestock, may pose a public health hazard in the city and implicate geographic spread of this bacteria species and its host.

Abstract
The aim of this study was to explore the relationships among gut microbiota disturbances and serum and spinal cord metabolic disorders in neuropathic pain. 16S rDNA amplicon sequencing and serum and spinal cord metabolomics were used to identify alterations in the microbiota and metabolite profiles in the sham rats and the chronic constriction injury (CCI) model rats. Correlations between the abundances of gut microbiota components at the genus level, the levels of serum metabolites, and pain-related behavioural parameters were analysed. Ingenuity pathway analysis (IPA) was applied to analyse the interaction networks of the differentially expressed serum metabolites. First, we found that the composition of the gut microbiota was different between rats with CCI-induced neuropathic pain and sham controls. At the genus level, the abundances of Helicobacter, Phascolarctobacterium, Christensenella, Blautia, Streptococcus, Rothia and Lactobacillus were significantly increased, whereas the abundances of Ignatzschineria, Butyricimonas, Escherichia, AF12, and Corynebacterium were significantly decreased. Additionally, 72 significantly differentially expressed serum metabolites and 17 significantly differentially expressed spinal cord metabolites were identified between the CCI rats and the sham rats. Finally, correlation analysis showed that changes in the gut microbiota was significantly correlated with changes in serum metabolite levels, suggesting that dysbiosis of the gut microbiota is an important factor in modulating metabolic disturbances in the context of neuropathic pain. In conclusion, our research provides a novel perspective on the potential roles of the gut microbiota and related metabolites in neuropathic pain.

Abstract
We describe a case of Ignatzschineria indica bacteremia in a patient with maggot infestation of a necrotic left leg wound. Ignatzschineria spp are an infrequent cause of infection in patients with wound myiasis. We review 16 cases described in published literature. Microbiologists and clinicians should be aware of uncommon bacteria, including Ignatzschineria spp, that may cause infection in patients with maggot-infested wounds such that these organisms are appropriately worked up and treated when found in clinical specimens.

Abstract
RATIONALE The presentation of sepsis and bacteremia in cutaneous and cavitary myiasis is uncommon. We present a patient, residing in a temperate region of the United States, with myiasis and sepsis from the emerging human pathogens Wohlfahrtiimonas chitiniclastica and Ignatzschineria indica. PATIENT CONCERNS A 37-year-old male patient with an 8-month history of chronic lymphedema and ulcers of the lower left extremity presented with myiasis of the left foot and leg. The patient was initially seen by his family practitioner many times and was prescribed antibiotics which he could not afford. Debridement of the myiasis was not conducted by the family practitioner due to the belief that the patient's current state of myiasis would effectively debride and eventually heal the chronic ulcers along with multiple antibiotic regimens. Over the 8-month period, the patient developed a progressive, painful, necrotizing infection of his lower left extremity. DIAGNOSES Physical examination clearly showed myiasis of the patient's lower left extremity, believed to be caused by Lucilia sericata (green bottle fly). Blood cultures revealed the presence of Providencia stuartii, W chitiniclastica, and I indica to be the underlying cause of sepsis and bacteremia. INTERVENTIONS All visible maggots were extracted, debridement of devitalized tissue was performed, and the leg ulcers were wrapped in pH neutral bleach. The patient was initially treated with a broad-spectrum antibiotic regimen of vancomycin, clindamycin, piperacillin, and tazobactam which, following clinical improvement, was de-escalated to cefepime. OUTCOMES The fly larvae and maggots were removed from the extremity by scrubbing, pulse lavage, and filing away the callused tissue. Additionally, the patient's sepsis and bacteremia, caused by W chitiniclastica and I indica, were successfully treated through antibiotic intervention. Amputation was avoided. LESSONS The use of pulse lavage and chlorhexidine-soaked brushes for the removal of cavitary myiasis is an effective and minimally invasive procedure which does not cause additional damage to surrounding tissue. W chitiniclastica and I indica are emerging bacteria that have known association to parasitic fly myiasis in humans and are capable of causing sepsis and/or bacteremia if not accurately identified and treated promptly.

Abstract
Five bacterial strains, UAE-HKU57T, UAE-HKU58, UAE-HKU59, UAE-HKU60 and UAE-HKU61, were isolated in Dubai, UAE, from necrotic foot tissue samples of four dromedaries (Camelus dromedarius) and associated maggots (Wohrlfartia species). They were non-sporulating, Gram-negative, non-motile bacilli. They grew well under aerobic conditions at 37 °C, but not anaerobically. The pH range for growth was pH 7.0-9.0 (optimum, pH 7.5-8.0) and the strains could tolerate NaCl concentrations (w/v) up to 2 % (optimum, 0.5 %). They were catalase- and cytochrome oxidase-positive, but caseinase-, gelatinase- and urease-negative. Their phenotypic characters were distinguishable from other closely related species. Phylogenetic analyses of the almost-complete 16S rRNA gene and partial 23S rRNA gene, gyrB, groEL and recA sequences revealed that the five isolates were most closely related to undescribed Ignatzschineria strain F8392 and Ignatzschineria indica, but in most phylogenies clustered separately from these close relatives. Average nucleotide identity analysis showed that genomes of the five isolates (2.47-2.52 Mb, G+C content 41.71-41.86 mol%) were 98.00-99.97% similar to each other, but ≤87.18 % similar to other Ignatzschineriaspecies/strains. Low DNA relatedness between the five isolates to other Ignatzschineriaspecies/strains was also supported by Genome-to-Genome Distance Calculator analysis. The chemotaxonomic traits of the five strains were highly similar. They were non-susceptible (intermediate or resistant) to tetracycline and resistant to trimethoprim/sulphamethoxazole. The name Ignatzschineria cameli sp. nov. is proposed to accommodate these five strains, with strain UAE-HKU57T (=CCOS1165T=NBRC 113042T) as the type strain.

Abstract
Introduction Ignatzschineria is a recently recognized genus associated with larvae infestation Members of this genus are pathogens infrequently implicated in human disease. During the last decade, fewer than 10 cases of infection with Ignatzchineria species have been reported around the world. Bacteria of the genera Ignatzchineria and Wohlfahrtiimonas have been isolated from larvae of the parasitic fly Wohlfahrtia magnifica, which is found in Europe, Asia and North Africa, and is associated with myiasis in several animal species, but rarely in humans. Case presentation We report the first case of sepsis associated with complicated skin and soft tissue infection caused by I. indica in Latin America. Conclusion The clinical and molecular findings in our report add information to the accumulating data on emerging pathogens of this type, their geographic distribution, the correlation between the emergence of infectious diseases and social and economic inequalities, as well as the effects of global climate changes on potentially unusual distribution of vectors. We consider that fly larvae should be regarded as a potential source of specific arthropod-borne bacterial systemic infections.

Abstract
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. The patient improved after treatment with cefepime followed by levofloxacin.
