Lin WH, Tsai TS, Chuang PC. The Presence of Four Pathogenic Oral Bacterial Species in Six Wild Snake Species from Southern Taiwan: Associated Factors. Microorganisms 2024; 12:263. [PMID: 38399667 PMCID: PMC10891919 DOI: 10.3390/microorganisms12020263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 01/23/2024] [Accepted: 01/23/2024] [Indexed: 02/25/2024] Open
Abstract
The oral cavity of snakes serves as a habitat for various microorganisms, some of which may include potential zoonotic pathogens posing risks to hosts and causing wound infections in snakebite victims. Clinical studies on snakebite cases in Taiwan have identified specific pathogens, such as Enterococcus faecalis (Gram-positive), Morganella morganii, Aeromonas hydrophila, and Pseudomonas aeruginosa (Gram-negative). However, the prevalence of these bacteria in the oral cavity of wild snakes remains largely unknown. This study investigated the occurrence of these bacteria in six wild snake species (Naja atra, Bungarus multicinctus, Trimeresurus stejnegeri, Protobothrops mucrosquamatus, Boiga kraepelini, and Elaphe taeniura friesi) from southern Taiwan, along with factors influencing their presence. Oropharyngeal swab samples were collected from a substantial number of wild-caught snakes (n = 1104), followed by DNA extraction, polymerase chain reaction, and gel electrophoresis. The band positions of samples were compared with positive and negative controls to determine the presence of target bacteria in each sample. The overall occurrence rates were 67.4% for E. faecalis, 31.5% for M. morganii, 8.2% for A. hydrophila, and 7.7% for P. aeruginosa. Among snake species, B. kraepelini exhibited dominance in E. faecalis (93.4%), A. hydrophila (17.1%), and P. aeruginosa (14.5%), while male N. atra showed dominance in M. morganii (51.3%). The occurrence of E. faecalis was lowest in winter. The results of multiple logistic regression analyses suggest that factors such as species, sex, temperature, season, and coexisting pathogens may have a significant impact on the occurrence of target bacteria. These findings have implications for wildlife medicine and snakebite management.

Abstract
INTRODUCTION The members of the tribe Proteeae, Morganella and Providencia are being increasingly recognized as important pathogens. The spectrum of disease caused by them is wide and in reported cases, the mortality is high. Previously both of these pathogens were considered to be rare pathogens as the potential to cause nosocomial transmission and infection was not much studied. But their phenomenal evolution and increase in multidrug-resistance (MDR) strains of these pathogens are posing a major threat toward public health throughout the world. METHODS This present study was carried out from July 2018 to December 2018 on all the pus and body fluid samples that were received in the Department of Microbiology. Samples were processed as per the standard Microbiological guidelines and also were analyzed for their antimicrobial susceptibility profile as per Clinical Laboratory Standards Institute. RESULTS Out of 8425 samples received, 2140 were culture positive, amongst which 19 samples (0.89%) were positive for Providencia species (9) and Morganella morganii(10). The male : female ratio of these 19 patients was 2.8 : 1 and maximum patients (13) belonged to 20-60 years. As far as risk factors are concerned, maximum patients were diabetics (7) followed by abnormal liver function tests (6), concomitant UTI (6), history of invasive procedure (5), prior exposure to antibiotics (5) and urinary catheterization (4). About 6 were polymicrobial infections. Antibiotic susceptibility patterns revealed that Providencia strains were sensitive to ampicillin- sulbactum (77.7%) and amikacin (77.7%), while all Morganella strains were 100% sensitive to tobramycin and piperacillintazobactam. CONCLUSION This study heralds in need for more research in this area as infections caused by these two pathogens are on the rise. Moreover, resistance to antimicrobials is also an increasingly common problem thus delaying the treatment and prognosis of the disease.

Abstract
Background Morganella morganii is a species of Gram-negative enteric rod found in normal human gut flora. Pathologically, this most often presents as urinary tract infections, wound infections, and bacteremia. It is highly uncommon for M. morganii to be implicated in a central nervous system infection, with only 12 reported cases of parenchymal abscesses or meningitis. Case Description A previously healthy 13-month-old female presented with fever of unknown origin and had a witnessed seizure during evaluation. A large left subdural fluid collection was identified, and the patient underwent emergent burr hole drainage and subdural drain placement. Cultures demonstrated M. morganii empyema, and she subsequently completed a course of directed antibiotics. Six months following surgery, she has no further clinical or radiographic evidence of infection, seizures, or neurological sequelae. Conclusion We describe the first reported case of isolated subdural empyema caused by M. morganii. The child was successfully treated with the evacuation of the empyema and direct antibiotics with no lasting neurological injury.

Abstract
BACKGROUND There are few studies of Morganella bacteremia. We evaluated risk factors and outcome of patients with Morganella bacteremia. METHODS Medical records of patients with Morganella bacteremia were reviewed (1997-2014). Control group patients with Escherichiacoli sepsis were matched by year of diagnosis and infection acquisition site. RESULTS The study group included 136 adult patients. Mean age and gender of study and control groups were similar. Complicated soft tissue infection was more prevalent in the study group (30% versus 3.2%, p < 0.05). The Charlson Comorbidity Index (CCI) was higher in the study group (4.3 ± 2.5 versus 3.4 ± 2.8, p < 0.05). Only 78 (62%) of the study patients versus 101 (83%) of the control group (p < 0.05), received appropriate empirical antibiotic treatment. A significantly higher in-hospital mortality rate (42% versus 25%, p < 0.05) as well as longer length of stay (25 ± 22 versus 14 ± 16 days, p < 0.05) was observed in the study group. Multivariate analysis revealed that a debilitative state, a CCI > 4, septic shock and a clinical syndrome other than UTI were all significant risk factors for mortality (p < 0.05). CONCLUSIONS Patients with Morganellamorganii sepsis had more co-morbidities and a worse degree of sepsis. There is an increased risk of inappropriate empirical treatment, longer hospitalization and higher death rate.

Abstract
BACKGROUND While uncommon, iliopsoas abscesses can become the underlying cause of a fever of unknown origin. Even in such cases, it is considered rare for an iliopsoas abscess to extend into the subcutaneous space. CASE REPORT A 74-year-old woman with a history of schizophrenia was referred to our hospital with a high-grade fever. The patient was unaware of her febrile status prior to admission. There was no previous hospital admission. Examination revealed a non-tender mass in the lower right back that the patient had been aware of for approximately 1 month. Initially, we considered a subcutaneous abscess; however, computed tomography (CT) detected a large mass in the right retroperitoneum, which extended into the adjacent subcutaneous space. Surgical drainage was performed. M. morganii was detected in fluid evacuated from the abscess and in a urine culture. Blood cultures were negative. A repeat enhanced CT revealed a right renal abscess with staghorn calculus. This iliopsoas abscess was considered to be due to a renal abscess. The combination of a minimally aggressive bacterial species and the absence of disease awareness resulted in uncontrolled abscess growth in this case. Surgical drainage and salvage nephrectomy was subsequently performed, and she was discharged to a nursing home. CONCLUSIONS M. morganii can lead to massive abscess formation without an underlying immunocompromised status. Iliopsoas abscesses can surreptitiously extend into the subcutaneous space; therefore, not all abscesses observable from the surface are necessarily subcutaneous in origin.

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 Agricultural activities inevitably result in anthropogenic interference with natural habitats. The diet and the gut microbiota of farmland wildlife can be altered due to the changes in food webs within agricultural ecosystems. In this work, we compared the diet and intestinal microbiota of the frog Fejervarya limnocharis in natural and farmland habitats in order to understand how custom farming affects the health of in vivo microbial ecosystems. RESULTS The occurrence, abundance, and the numbers of prey categories of stomach content were significantly different between the frogs inhabiting natural and farmland habitats. In addition, differences in the abundance, species richness, and alpha-diversity of intestinal microbial communities were also statistically significant. The microbial composition, and particularly the composition of dominant microbes living in intestines, indicated that the land use practices might be one of factors affecting the gut microbial community composition. Although the first three dominant microbial phyla Bacteroidetes, Firmicutes, and Proteobacteria found in the intestines of frogs were classified as generalists among habitats, the most dominant gut bacterial phylum Bacteroidetes in natural environments was replaced by the microbial phylum Firmicutes in farmland frogs. Increased intestinal microbial richness of the farmland frogs, which is mostly contributed by numerous microbial species of Proteobacteria, Actinobacteria, Acidobacteria, and Planctomycetes, not only reflects the possible shifts in microbial community composition through the alteration of external ecosystem, but also indicates the higher risk of invasion by disease-related microbes. CONCLUSIONS This study indicates that anthropogenic activities, such as the custom farming, have not only affected the food resources of frogs, but also influenced the health and in vivo microbial ecosystem of wildlife.

Abstract
A 79-year-old man on continuous ambulatory peritoneal dialysis (CAPD) developed abdominal pain and cloudy peritoneal fluid two days after colonoscopy that revealed multiple diverticula. The white blood cell count was 9,000 cells/μL, C-reactive protein level was 6.86 mg/dL, and the white blood cell count of the peritoneal fluid was 7,800 cells/μL, suggesting acute peritonitis. Empiric therapy consisting of cefazolin and ceftazidime slowly improved the patient's symptoms. The initial microbiological examination of the peritoneal fluid demonstrated Morganella morganii. He was changed from CAPD to hemodialysis. It is important to consider M. morganii peritonitis in patients with colonic diverticula.

Abstract
Sulfhemoglobinemia is a rare disorder characterized by the presence of sulfhemoglobin in the blood. It is typically drug-induced and may cause hypoxia, end-organ damage, and death through oxygen deprivation. We present here a case of non-drug-induced sulfhemoglobinemia in a 7-day-old preterm infant complicated by hemolytic anemia. Microbiota compositional analysis of fecal samples to investigate the origin of hydrogen sulphide revealed the presence of Morganella morganii at a relative abundance of 38% of the total fecal microbiota at the time of diagnosis. M morganii was not detected in the fecal samples of 40 age-matched control preterm infants. M morganii is an opportunistic pathogen that can cause serious infection, particularly in immunocompromised hosts such as neonates. Strains of M morganii are capable of producing hydrogen sulphide, and virulence factors include the production of a diffusible α-hemolysin. The infant in this case survived intact through empirical oral and intravenous antibiotic therapy, probiotic administration, and red blood cell transfusions. This coincided with a reduction in the relative abundance of M morganii to 3%. Neonatologists should have a high index of suspicion for intestinal pathogens in cases of non-drug-induced sulfhemoglobinemia and consider empirical treatment of the intestinal microbiota in this potentially lethal condition.

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.

We report herein a case of Morganella morganii-associated acute purulent pericarditis that developed 3 years after allogenic bone marrow transplantation. The patient was successfully treated with surgical drainage and cefotaxime for 6 weeks. Splenectomy and immunosuppression for chronic GVH-D are likely to have favored the development of this rare infectious complication after BMT. M. morganii should be added to the list of bacteria causing purulent pericarditis, especially in immunocompromised hosts.

Abstract
Central nervous system (CNS) infection with Morganella morganii is very rare. We describe a 38-year-old female patient with frontal brain abscess caused by M morganii who was unsuccessfully treated. We also review all reported cases of Morganella CNS infections with an emphasis on treatment modalities and outcomes. Aggressive surgical management and appropriate antimicrobial therapy can lead to cure, but the mortality rate for these infections remains high.
