The urochloa foliar blight and collar rot pathogen rhizoctonia solani AG-1 IA emerged in South America via a host shift from rice
(The American Phytopathological Society, 2015-10-22)
The fungus Rhizoctonia solani anastomosis group (AG)-1 IA emerged in the early 1990s as an important pathogen causing foliar blight and collar rot on pastures of the genus Urochloa (signalgrass) in South America. We tested ...
Pathogenicity, colony morphology and diversity of isolates of Guignardia citricarpa and G-mangiferae isolated from Citrus spp.
(Springer, 2008-02-01)
In the present study, the pathogenicity of 36 isolates of Guignardia species isolated from asymptomatic 'Tahiti' acid lime fruit peels and leaves, 'Pera-Rio' sweet orange leaves and fruit peel lesions, and a banana leaf ...
EVALUATION OF DIFFERENT TECHNIQUES FOR THE DIFFERENTIATION OF PATHOGENIC AND NON PATHOGENIC STRAINS OF YERSINIA-ENTEROCOLITICA
(Soc Brasileira Microbiologia, 1995-04-01)
Different methods and tests have been used to evaluate the pathogenic potential of distinct Y. enterocolitica serotypes and biotypes. We tested a total of 60 Y. enterocolitica strains, being 25 of human origin (serotype ...
STUDIES ON THE RELATIONSHIP BETWEEN THE PATHOGENICITY OF PARACOCCIDIOIDES-BRASILIENSIS IN MICE AND ITS GROWTH-RATE UNDER DIFFERENT OXYGEN ATMOSPHERES
(Kluwer Academic Publ, 1991-05-01)
We performed comparative studies of the pathogenicity of six strains of Paracoccidioides brasiliensis (Bt-9, Bt-4, Pb-9, Pb-18, Bt-7 and B-1183) for young adult male ddY mice and growth rate of each strain under different ...
Convergent evolution and mimicry of protein linear motifs in host-pathogen interactions
(Elsevier Science London, 2015-06)
Pathogen linear motif mimics are highly evolvable elements that facilitate rewiring of host protein interaction networks. Host linear motifs and pathogen mimics differ in sequence, leading to thermodynamic and structural ...
Highly pathogenic and multidrug resistant avian pathogenic escherichia coli in free-range chickens from Brazil
(2019-01-01)
Avian pathogenic Escherichiacoli (APEC) virulence mechanism has been continuously studied and it is believed to be multifactorial and because of this, this work aimed to characterize potentially APEC strains isolated from ...

Influence of pathogens causing clinical mastitis on reproductive variables of dairy cows
(2020-04-01)
In dairy cattle, mastitis is a disease of the mammary gland caused by pathogens such as bacteria, viruses, fungi, and algae. Mastitis causes economic losses to dairy farms as well as public health concerns. The reproductive ...
