Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici, is one of the important diseases of wheat. We used NGS technologies to generate a draft genome sequence of two highly virulent (46S 119 and 31) and a least virulent (K) pathotypes of P. striiformis from the Indian subcontinent. We generated ~24,000-32,000 sequence contigs (N50;7.4-9.2 kb), which accounted for ~86X-105X sequenc...

Wastewater is an important reservoir for Escherichia coli and can present significant acute toxicity if released into receiving water sources without being adequately treated. To analyze whether pathogenic E. coli strains that cause infections are in treated effluent and to recognize antibiotic profile. 476 confirmed isolates from two treatment Plants were characterized for the presence of vari...

Puccinia triticina is a highly damaging wheat pathogen. The efficacy of leaf rust control by genetic resistance mitigated the adaptive capacity pathogen, expressed as changes in its virulence combinations (pathotypes). An extensive P. population survey has been carried out France over last 30 years, describing evolutionary dynamics this pathogen response to cultivar deployment. We analysed data...

Genotypically different host specific pathotypes of Bursaphelenchus xylophilus have been identified. These pathotypes elicit different responses in pines depending on susceptibility, tolerance, or resistance. Continued passage of some of these pathotypes on fungal cultures leads to conversion to nonparasitic populations. These populations metabolize carbon substrates to ethanol by an anaerobic ...

A variety of virulence genes are associated with Escherichia coli mediated urinary tract infections. Particular sets of virulence factors shared by bacterial strains directing them through a particular pathogenesis process are called a "pathotype." Comparison of co-occurrence of potential urinary tract infection (UTI) virulence genes among different E. coli isolates from fecal and UTI collectio...

INTRODUCTION Infectious diarrhoea particularly due to pathogenic bacteria is a major health problem in developing countries, including India. Despite significant reports of diarrhoeagenic Escherichia coli (DEC) pathotypes around the globe, studies which address genetic relatedness, antibiogram profile and their correlation with respect to their isolation from different sources are sparse. The p...

Autotransporter (AT) protein-encoding genes of diarrheagenic Escherichia coli (DEC) pathotypes (cah, eatA, ehaABCDJ, espC, espI, espP, pet, pic, sat, and tibA) were detected in typical and atypical enteropathogenic E. coli (EPEC) in frequencies between 0.8% and 39.3%. Although these ATs have been described in particular DEC pathotypes, their presence in EPEC indicates that they should not be co...

Although Escherichia coli can be an innocuous resident of the gastrointestinal tract, it also has the pathogenic capacity to cause significant diarrheal and extraintestinal diseases. Pathogenic variants of E. coli (pathovars or pathotypes) cause much morbidity and mortality worldwide. Consequently, pathogenic E. coli is widely studied in humans, animals, food, and the environment. While there a...

Escherichia coli isolates (n = 300) collected from six sites in subtropical Brisbane, Australia, prior to and after storm events were tested for the presence of 11 virulence genes (VGs) specific to diarrheagenic pathotypes. The presence of eaeA, stx(1), stx(2), and ehxA genes specific for the enterohemorrhagic E. coli (EHEC) pathotype was detected in 56%, 6%, 10%, and 13% of isolates, respectiv...
