Abstract
Morganella morganii is an opportunistic Gram-negative bacillus commonly found in the human gastrointestinal tract and the environment. In adults, it is often associated with nosocomial infections, primarily surgical wound infections, urinary tract infections, and hepatobiliary infections. It is a rare cause of early-onset neonatal sepsis, with fewer than 15 reported cases in the literature. The authors aim to present a case of a low birth weight preterm born at 28 weeks' gestation, who developed early-onset neonatal sepsis due to M. morganii. We successfully treated the infection using a combination of third-generation cephalosporin and aminoglycoside, and in this report, we explain the rationale behind employing this antibiotic therapy.

Abstract
BACKGROUND Morganella morganii is a Gram-negative, rod-shaped, facultative anaerobic bacillus divided into two subspecies, morganii and sibonii. Previously classified as Proteus morganii, it belongs to human gut commensal microbiota. Nevertheless, on rare occasions, especially in nosocomial and postoperative environment as well as in patients with the impaired immune system and young children, it may cause potentially fatal systemic infection. OBJECTIVES The aim of our systematic review was to determine whether and what invasive infections in humans were caused by Morganella morganii and to estimate outcomes of administered antibiotic management. DATA SOURCES This systematic review was registered at the PROSPERO database of systematic reviews and meta-analyses before initiation of the research (registration number CRD42020171919). Study eligibility criteria and participants. patients of any age and both sex harbouring Morganella morganii as the only microorganism in bodily fluids or tissues, from where it was isolated and identified by one or more of the following diagnostic methods: conventional techniques including colony morphology, Vitek 2, API or BD Phoenix biochemical systems, as well as more sophisticated methods, such as Matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) and species-specific PCR for M. morganii. METHODS AND INTERVENTIONS We have systematically searched MEDLINE, EBSCO, SCOPUS, SCINDEX and GOOGLE SCHOLAR for case reports and case series with M. morganii invasive infections. RESULTS M. morganii can cause serious infections of different tissue in patients of any age. The most isolates were susceptible to ceftazidime, imipenem and amikacin. Majority of the patients completely recovered after antibiotic treatment. About 15% of the patients died despite of the therapy. Gentamicin was the most frequently used antibiotic in the treatment of infection caused by M. morganii. CONCLUSION M. morganii invasive infections should be taken into consideration by the clinicians, especially in hospital conditions, due to its high degree of mortality and high potential of this bacterium to develop multidrug resistance. Treatment of M. morganii infections should include gentamycin in combination with third generation cephalosporin or another antibiotic to which M. morganii is susceptible (after testing isolates for third cephalosporin generation for the production of AmpC β -lactamases).

Antibiotic Resistance and Virulence Profiles of Gram-Negative Bacteria Isolated from Loggerhead Sea Turtles ( Caretta caretta) of the Island of Maio, Cape Verde. Antibiotics (Basel) 2021; 10:antibiotics10070771. [PMID: 34202799 PMCID: PMC8300689 DOI: 10.3390/antibiotics10070771] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/18/2021] [Accepted: 06/21/2021] [Indexed: 11/16/2022] Open
Abstract
Previous studies revealed high levels of antimicrobial resistance (AMR) in loggerhead sea turtles (Caretta caretta), describing this species as prime reservoir of antimicrobial-resistant bacteria. This study aimed to characterise, for the first time, the AMR and virulence profiles of Gram-negative bacteria isolated from 33 nesting loggerhead turtles of the island of Maio, Cape Verde. Cloacal, oral, and egg content swab samples (n = 99) were collected and analysed using conventional bacteriological techniques. Shewanella putrefaciens, Morganella morganii, and Vibrio alginolyticus were isolated from the samples under study. The isolates obtained from this loggerhead subpopulation (North-East Atlantic) revealed lower levels of AMR, compared with the results of studies performed in other subpopulations (e.g., Mediterranean). However, the detection of resistance to carbapenems and multiple antimicrobial resistance indices higher than 0.20, raises concern about the potential association of these animals to points of high antimicrobial exposure. Furthermore, virulence phenotypic characterisation revealed that the isolates presented complex virulence profiles, including the ability to produce biofilms. Finally, due to their pathogenic potential, and considering the evidence of illegal consumption of turtle-related products on the island of Maio, the identified bacteria may represent a significant threat to public health.

Abstract
We describe a case of late onset Morganella morganii sepsis in an extremely low birth weight male neonate born at 23 and 4/7 weeks gestational age to a 30-year-old primigravid mother due to preterm labor. The mother was otherwise healthy with an unremarkable prenatal course. She received steroids and ampicillin prior to delivery. While initial blood cultures were negative, at day of life 4, the neonate developed signs of sepsis with leukocytosis and bandemia, and subsequent blood culture demonstrated growth of M. morganii . The patient then had spontaneous intestinal perforation on day of life 8 with peritoneal cultures growing M. morganii . The infant responded to standard therapy and survived to discharge, with few mild developmental delays upon outpatient follow-up. While M. morganii has been demonstrated in the neonatal population, it generally causes early onset sepsis and is associated with high mortality in preterm neonates. Here, we present this case of late onset neonatal sepsis with M. morganii complicated by spontaneous intestinal perforation, with survival in a 23 weeks gestation infant.

Abstract
Morganella morganii is a rare opportunistic pathogen that is known to cause urinary tract and intra-abdominal infections. Per our literature review, there are few case reports of neonatal sepsis associated with this organism but to our knowledge, there are no case reports of Morganella morganii causing fetal demise in published literature in the Englishlanguage. In this case report, we present a case of a 34-year-old pregnant woman who had a hospital course complicated by Morganella morganii, which eventually led to stillbirth.

Abstract
Histamine (scombroid) poisoning is a foodborne illness caused by ingestion of histamine-contaminated seafood; therefore, inhibition of the growth of histamine-producing bacteria is key for it prevention. Infection of pathogenic bacteria by bacteriophages (phages) is being developed to prevent multiple foodborne illnesses. Here, we describe the inhibitory effect of a phage mixture on growth and histamine accumulation of Morganella morganii subsp. morganii, the primary causative agent of histamine poisoning in fish meat. We isolated novel two phages, ΦMV-1 and ΦMV-4, which infected M. morganii subsp. morganii strains tested in this study. ΦMV-1 and ΦMV-4 belong to family Myoviridae. Pulsed-field gel electrophoresis revealed that these phages are jumbo bacteriophages with large genomes. The latent period, rise period and burst size of ΦMV-1 were 30 min, 60 min, and 224 PFU per infected cell, respectively, and those of ΦMV-4 were 60 min, 50 min, and 62 PFU per infected cell, respectively. A mixture of ΦMV-1 and ΦMV-4 effectively prevented regrowth of M. morganii subsp. morganii after phage treatment, suggesting that the phage mixture treatment is more effective for inhibition of growth and histamine accumulation by M. morganii subsp. morganii than single phage treatment. Treatment with phage mixture inhibited growth and histamine accumulation by M. morganii subsp. morganii in canned and fresh tuna. The phage mixture might be an effective way to prevent growth of the histamine producer and accumulation of histamine in seafood.

Abstract
OBJECTIVES A multidrug-resistant Morganella morganii strain (CQ-M7), isolated from the kidney of a diseased Chinese giant salamander in China, was examined with whole genome sequencing to better understand drug tolerance and its pathogenicity. METHODS The draft genome of the investigated strain was assembled using HGA assembler and annotated using Rapid Annotations Subsystems Technology (RAST) server. The contigs were annotated by the appropriate bioinformatics tools available on the National Center for Biotechnology Information (NCBI) website. Antibiotic resistance genes were detected by PCR. Pathogenicity of the isolate was performed on 30 healthy Chinese giant salamanders with different infection dosages. RESULTS The CQ-M7 strain showed resistance to multiple antimicrobials, especially to aminoglycoside and β-lactam antibiotics. Seventeen drug-resistance genes were detected, which were related to β-lactams, aminoglycosides, fluoroquinolones, tetracyclines, peptide antibiotic, and fosfomycin resistance. Sequence analysis showed the assembled genome size to be 4 966 326bp with 51.16% of GC content, containing 4587 protein-coding genes, 71 pseudogenes, five rRNAs, 80 tRNAs, and five noncoding RNAs. The genome sequence was deposited in GenBank under accession number RQIJ00000000. Artificial infection results indicated that the CQ-M7 strain was a low-virulence strain for the Chinese giant salamander. CONCLUSION It is believed that this is the first draft genome of Chinese giant salamander original Morganella morganii strain harbouring multiple antibiotic resistance genes in China. The reported genome sequence could provide insights into antibiotic resistance mechanisms and control strategies of Morganella morganii.

Abstract
BACKGROUND Cephalohematomas are relatively common sub-periosteal collections of blood that tend to resolve spontaneously without treatment. Rarely, they become infected and can be associated with underlying osteomyelitis, meningitis, or sepsis. Common pathogens include Escherichia coli and Staphylococcus species. ILLUSTRATIVE CASE This report describes the first case of a neonate developing an infected right parietal cephalohematoma and underlying osteomyelitis caused by Morganella morganii, which was cultured in blood and cephalohematoma aspirate. This infant male, whose risk factors included vacuum extraction during delivery and suspected post-natal pneumonia, responded well to a 6-week course of intravenous meropenem with complete resolution of both lesions. CONCLUSION When an infected cephalohematoma is suspected, aspiration of hematoma fluid should be performed for both diagnostic and therapeutic purposes. Infectious symptoms should warrant prompt investigation and treatment, which may include drainage, debridement, and antibiotics. This report demonstrates that the combination of an infected cephalohematoma and underlying osteomyelitis might not be as uncommon as previously believed.

Abstract
Morganella morganii belongs to the tribe Proteeae of the Enterobacteriaceae family. This species is considered as an unusual opportunistic pathogen that mainly causes post-operative wound and urinary tract infections. However, certain clinical M. morganii isolates present resistance to multiple antibiotics by carrying various resistant genes (such as blaNDM-1, and qnrD1), thereby posing a serious challenge for clinical infection control. Moreover, virulence evolution makes M. morganii an important pathogen. Accumulated data have demonstrated that M. morganii can cause various infections, such as sepsis, abscess, purple urine bag syndrome, chorioamnionitis, and cellulitis. This bacterium often results in a high mortality rate in patients with some infections. M. morganii is considered as a non-negligent opportunistic pathogen because of the increased levels of resistance and virulence. In this review, we summarized the epidemiology of M. morganii, particularly on its resistance profile and resistant genes, as well as the disease spectrum and risk factors for its infection.

Abstract
BACKGROUND In captive breed turtles and tortoises conjunctival disease is common. Our aim was to investigate the bacterial and fungal flora present in the eyes of healthy and pathological chelonians and to compare findings in turtles with those in tortoises. RESULTS Samples were taken from the conjunctival sacs of 34, diseased and healthy, chelonians (18 tortoises and 16 turtles) and submitted to bacterial and fungal investigation. All samples showed bacterial growth. Thirteen animals (38%), harboured a single bacterial species as sole isolate and twenty-one animals (62%) harboured more than one species. Detection of multiple bacterial infection was clearly greater in tortoises compared to turtles. Most frequently isolated bacterial species were Bacillus spp. (13 isolates), Staphylococcus xylosus (10 isolates), Sphingomonas paucimobilis (6 isolates), Staphylococcus sciuri and Aeromonas hydrophila/caviae (each 5 isolates), Ochrobactrum anthropi (3 isolates), Citrobacter freundii, Enterobacter cloacae and Pseudomonas luteola (each 2 isolates). Only one isolate of Kocuria varians/rosea, Staphylococcus aureus, Staphylococcus auricularis, Staphylococcus haemolyticus, Staphylococcus lentus, Morganella morganii, Pasteurella multocida, Pasteurella pneumotropica/haemolytica, Proteus spp., Pseudomonas putida, Salmonella enterica ssp. arizonae, Stenotrophomonas maltophilia and Vibrio parahaemolyticus was evidenced. The presence in 8 animals of Mycoplasma spp. and in 1 animal with severe conjunctivitis of Chlamydia spp. was detected by PCR. Candida spp. was also isolated from two healthy animals. CONCLUSIONS A clear predominance of Gram positive isolates in tortoises and Gram negative isolates in turtles was found. However, we cannot ascribe the observed difference to the diversity of animal species, as other factors, including especially different characteristics of the living environments, may play a role. Almost all bacterial species isolated may have clinical significance, mostly as opportunistic pathogens, both for humans and animals. That chelonians are often carrier of bacteria with zoonotic potential is a well-known fact, in particular with regard to Salmonella spp. Therefore, it is not surprising the detection of a strain of Salmonella enterica ssp. arizonae in the eye of one of the animals tested. Worthy of note is the finding of Chlamydia spp. in a severe case of conjunctivitis, though we cannot epidemiologically assess a cause-effect relationship between presence of chlamydia and disease.

Abstract
Although Morganella morganii causes a variety of clinical infections, there are limited studies on M. morganii bacteremia after the year 2000. A total of 109 patients with M. morganii bacteremia at a medical center in Taiwan from 2003 to 2012 were studied. Among them, 30.3 % had polymicrobial bacteremia and 75.2 % had community-acquired infection. The most common underlying diseases were hypertension (62.4 %) and diabetes mellitus (38.5 %). The urinary tract (41.3 %) was the major portal of entry, followed by the hepatobiliary tract (27.5 %), skin and soft tissue (21.1 %), and primary bacteremia (10.1 %). Susceptibility testing of M. morganii isolates showed ubiquitous resistance to first-generation cephalosporins and ampicillin-clavulanate; resistance rates to gentamicin, piperacillin-tazobactam, and ciprofloxacin were 30.3 %, 1.8 %, and 10.1 %, respectively. Overall, the 14-day mortality was 14.7 %. Univariate analysis revealed that elevated blood urea nitrogen (BUN) values [p = 0.0137, odds ratio (OR) 5.26], intensive care unit (ICU) admission (p = 0.011, OR 4.4), and higher Acute Physiology and Chronic Health Evaluation II (APACHE II) scores (p < 0.001, OR 1.62) were significantly associated with mortality. The APACHE II score remained the only significant risk factor for mortality in multivariate analysis (p = 0.0012, OR 1.55). In conclusion, M. morganii bacteremia patients were mostly elderly, with one or more comorbidities. Most of the patients had community-acquired infection via the urinary and hepatobiliary tracts. Furthermore, prognosis can be predicted according to disease severity measured by the APACHE II score.

Abstract
BACKGROUND The opportunistic enterobacterium, Morganella morganii, which can cause bacteraemia, is the ninth most prevalent cause of clinical infections in patients at Changhua Christian Hospital, Taiwan. The KT strain of M. morganii was isolated during postoperative care of a cancer patient with a gallbladder stone who developed sepsis caused by bacteraemia. M. morganii is sometimes encountered in nosocomial settings and has been causally linked to catheter-associated bacteriuria, complex infections of the urinary and/or hepatobiliary tracts, wound infection, and septicaemia. M. morganii infection is associated with a high mortality rate, although most patients respond well to appropriate antibiotic therapy. To obtain insights into the genome biology of M. morganii and the mechanisms underlying its pathogenicity, we used Illumina technology to sequence the genome of the KT strain and compared its sequence with the genome sequences of related bacteria. RESULTS The 3,826,919-bp sequence contained in 58 contigs has a GC content of 51.15% and includes 3,565 protein-coding sequences, 72 tRNA genes, and 10 rRNA genes. The pathogenicity-related genes encode determinants of drug resistance, fimbrial adhesins, an IgA protease, haemolysins, ureases, and insecticidal and apoptotic toxins as well as proteins found in flagellae, the iron acquisition system, a type-3 secretion system (T3SS), and several two-component systems. Comparison with 14 genome sequences from other members of Enterobacteriaceae revealed different degrees of similarity to several systems found in M. morganii. The most striking similarities were found in the IS4 family of transposases, insecticidal toxins, T3SS components, and proteins required for ethanolamine use (eut operon) and cobalamin (vitamin B12) biosynthesis. The eut operon and the gene cluster for cobalamin biosynthesis are not present in the other Proteeae genomes analysed. Moreover, organisation of the 19 genes of the eut operon differs from that found in the other non-Proteeae enterobacterial genomes. CONCLUSIONS This is the first genome sequence of M. morganii, which is a clinically relevant pathogen. Comparative genome analysis revealed several pathogenicity-related genes and novel genes not found in the genomes of other members of Proteeae. Thus, the genome sequence of M. morganii provides important information concerning virulence and determinants of fitness in this pathogen.
