A multiplex PCR was designed to detect Escherichia coli O104:H4, a hybrid pathotype of Shiga toxigenic and enteroaggregative E. coli, in cattle feces. A total of 248 fecal samples were tested, and 20.6% were positive for serogroup O104. The O104 isolates did not carry genes characteristic of the virulent hybrid strain.

We report the complete genome sequence of a Newcastle disease virus (NDV) isolate, NDV-D1/1998, from an apparently healthy village chicken in South India. This class II, genotype II virus is 15,186 nucleotides in length with unique amino acid variations and was found to be a velogenic pathotype by standard pathogenicity tests.

Shiga toxin-producing Escherichia coli (STEC) O80:H2 is an uncommon hybrid pathotype that has emerged in Switzerland and France. Here, we report the draft genome sequences of 19 stx -harboring strains isolated between 2003 2019 from patients Switzerland.

Globodera rostochiensis and G. pallida responded similarly to hatch stimulation by potato root leachate, but proportionally more second-stage juveniles (J2s) of G. rostochiensis hatched than of G. pallida in response to picrolonic acid, sodium thiocyanate, alpha-solanine, and alpha-chaconine. Fractionation of the potato root leachate identified hatching factors with species-selective (active to...

avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. the presence of avian influenza viruses (aiv) in chickens in iran has not been previously reported. an avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in july 1998. three aiv isolates designated as 101, 102 and 10...

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...

Avian pathogenic Escherichia coli (APEC) infections are responsible for significant losses in the poultry industry worldwide. The disease might present as different local infections or as septicemia. Here, we present the draft genome sequences of three Brazilian APEC strains isolated from different kinds of infections. The availability of these APEC genome sequences is important for gaining a t...
