Abstract
Early and precise detection and identification of various pathogens are essential for epidemiological monitoring, disease management, and reducing the prevalence of clinical infectious diseases. Traditional pathogen detection techniques, which include mass spectrometry, biochemical tests, molecular testing, and culture-based methods, are limited in application and are time-consuming. Next generation sequencing (NGS) has emerged as an essential technology for identifying pathogens. NGS is a cutting-edge sequencing method with high throughput that can create massive volumes of sequences with a broad application prospects in the field of pathogen identification and diagnosis. In this review, we introduce NGS technology in detail, summarizes the application of NGS in that identification of different pathogens, including bacteria, fungi, and viruses, and analyze the challenges and outlook for using NGS to identify clinical pathogens. Thus, this work provides a theoretical basis for NGS studies and provides evidence to support the application of NGS in distinguishing various clinical pathogens.

Abstract
PURPOSE Diarrheal disorders particularly cholera cause a significant threat resulting in high morbidity and mortality in the coastal and tribal areas of Odisha. Two sequential diarrheal outbreaks reported in 2016 from Balasore and Rayagada districts of Odisha were investigated to find out the causative organisms, antibiogram profile and molecular analysis of the isolated pathogens. METHOD Bacteriological analysis and antibiogram profiles of the pathogens were carried out as per the standard procedure followed. The double mismatch amplification mutation (DMAMA) PCR for ctxB gene, sequencing and pulse-field gel electrophoresis (PFGE) were carried out on Vibrio cholerae O1 strains. RESULTS The rectal swabs and water samples from these districts were positive for V. cholerae O1 Ogawa biotype El Tor. The V. cholerae O1 strains isolated from Balasore district were multidrug resistant to many antibiotics which differed from the isolates of Rayagada district. The DMAMA PCR assay on all clinical and water isolates from these areas and some strains from other districts exhibited ctxB7 allele of V. cholerae O1 which correlates with the sequencing results having different pulsotypes. The Haitian variant of V. cholerae O1 strains which were compared with the V. cholerae O1 strains of 1999 and 2000 exhibited different pulsotypes. CONCLUSION The present study reports cholera outbreaks due to multidrug resistant ctxB7 allele of V. cholerae O1 from both coastal (Balasore) and tribal (Rayagada) areas of Odisha.

Abstract
Vibrio cholerae is the etiological agent of cholera, a severe diarrheal disease, which can occur as either an epidemic or sporadic disease. Cholera pandemic-causing V. cholerae O1 and O139 serogroups originated from the Indian subcontinent and spread globally and millions of lives are lost each year, mainly in developing and underdeveloped countries due to this disease. V. cholerae O1 is further classified as classical and El Tor biotype which can produce biotype specific cholera toxin (CT). Since 1961, the current seventh pandemic El Tor strains replaced the sixth pandemic strains resulting in the classical biotype strain that produces classical CT. The ongoing evolution of Atypical El Tor V. cholerae srains encoding classical CT is of global concern. The severity in the pathophysiology of these Atypical El Tor strains is significantly higher than El Tor or classical strains. Pathogenesis of V. cholerae is a complex process that involves coordinated expression of different sets of virulence-associated genes to cause disease. We are yet to understand the complete virulence profile of V. cholerae, including direct and indirect expression of genes involved in its survival and stress adaptation in the host. In recent years, whole genome sequencing has paved the way for better understanding of the evolution and strain distribution, outbreak identification and pathogen surveillance for the implementation of direct infection control measures in the clinic against many infectious pathogens including V. cholerae. This review provides a synopsis of recent studies that have contributed to the understanding of the evolution, distribution and genetics of the seventh pandemic Atypical El Tor V. cholerae strains.

Abstract
Cholera posed a significant threat causing outbreaks/epidemics with high morbidity and mortality in Odisha. This study envisages the characterisation of isolated pathogen from two cholera outbreaks reported in 2018 and 2019 from Bargarh and Rayagada districts of Odisha respectively. Vibrio cholerae O1 were isolated following standard techniques. The different virulent and drug resistant genes were detected by multiplex PCR assays; whereas the ctxB genotypes were characterised through double mismatch amplification mutation (DMAMA) PCR assay. The ctxB genes were further sequenced and pulse-field gel electrophoresis (PFGE) was done on some selected strains. The clinical and water isolates of Haitian variant (HCT) V. cholerae O1 Ogawa biotype El Tor with multi drug resistant strains were isolated from both the places. All the V. cholerae O1 strains were positive for virulence genes. The antibiotic resistant genes like dfrA1 (100%), strB (76.9%), intSXT (61.5%) were detected. The PFGE results on V. cholerae O1 strains exhibited two different pulsotypes. These cholera outbreaks were due to multidrug resistant HCT variant V. cholerae O1 strains which were circulating and caused the cholera outbreaks in Odisha. So continuous surveillance on diarrheal disorders is highly essential to prevent the future diarrheal outbreaks in this region.
