Determination of Phylogroups, Pathotypes and Antibiotic Resistance Profiles of E. coli Isolates from Freshwater and Wastewater in the City of Panama

Pathogens
Untreated water bodies are critical ecological niches where environmental conditions can drive the adaptive evolution of bacterial populations, enabling them to acquire new traits such as antibiotic-resistance genes.

Quarantine nematode species and pathotypes potentially dangerous for domestic potato production: populations diversity and the genetics of potato resistance

Вавиловский журнал генетики и селекции, 2020
The review considers quarantine species and nematode pathotypes potentially dangerous for domestic potato production. Potatoes are affected by more than 30 types of parasitic nematodes, but the review focuses on the most harmful representatives of genera

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Diversity and distribution of pathotypes of the soybean rust fungus Phakopsora pachyrhizi in east africa.

, 2021
Phakopsora pachyrhizi is a biotrophic fungus that causes rust on soybean, leading to devastating yield losses. Development of resistant cultivars for deployment in different geographic regions requires a comprehensive understanding of the prevalent P ...

Characterisation of Haemolytic Uropathogenic Escherichia coli Isolated From Dogs and Cats

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
The present study characterises 51 canine and feline haemolytic E. coli isolates from urinary tract infections by a polyphasic approach, including susceptibility testing, CH‐clonotyping, and DNA microarrays. The majority of isolates belonged to phylogenetic group B2 and were classified as extraintestinal pathogenic E.

Development Of Pathotype-Specific Pcr Tests For The Identification Of Synchytrium Endobioticum Pathotype 1 (Sendo D1)

, 2014
Synchytrium endobioticum is a severe pathogen of potato causing wart disease. For this obligate fungus many pathotypes (races) exist, which are pathogenic or nonpathogenic to different cultivars of potato. To determine to which race an isolate belongs, two biological assays are used on a set of different potato cultivars: the Spieckermann and the ...

Pathotyping Escherichia coli by Using Miniaturized DNA Microarrays [PDF]

Applied and Environmental Microbiology, 2007
ABSTRACT The detection of virulence determinants harbored by pathogenic Escherichia coli is important for establishing the pathotype responsible for infection. A sensitive and specific miniaturized virulence microarray containing 60 oligonucleotide probes was developed. It detected six E. coli

Wheat germplasm screening for stem rust resistance using conventional and molecular techniques

Czech Journal of Genetics and Plant Breeding, 2011
In Central Asia, stem rust (Puccinia graminis f.sp. tritici) causes considerable damage, especially during growing seasons with high rainfall. Ug99 is a race of stem rust that is virulent to the majority of wheat varieties.

H5N1 Clade 2.3.4.4b Infections in Domestic Cats During an Avian Influenza Outbreak in Italy: Implications for One Health Surveillance

Influenza and Other Respiratory Viruses, Volume 20, Issue 9, September 2026.
ABSTRACT Background H5Nx goose/Guangdong (Gs/GD) lineage highly pathogenic avian influenza (HPAI) viruses pose a significant public health threat due to their global spread, mutation accumulation, and expanding host range. The descendant clade 2.3.4.4b has been causing widespread infections in birds and increasing spillover events in mammals.

POWDERY MILDEW ON ROSES: PATHOTYPE SCREENING [PDF]

Acta Horticulturae, 2002
Monospore cultures of rose powdery mildew (Sphaerotheca pannosa var. rosae) were established from isolates collected on outdoor grown roses at different locations in Belgium. These monospore cultures were tested on rose cultivars and species with different levels of natural resistance to examine the possible existence of different pathotypes. Therefore
