Breeding systems in Echinococcus granulosus (Cestoda; Taeniidae) : selfing or outcrossing?
Haag, Karen Luisa; Araujo, Aldo Mellender de; Gottstein, Bruno; Siles-Lucas, M.; Thompson, R. C. A.; Zaha, Arnaldo (1999) [Journal article]We used the PCR±SSCP method followed by sequencing in order to assess the genetic variability of coding and noncoding parts of the genome of Echinococcus granulosus (Cestoda; Taeniidae) and to test whether or not the ... -
Draft genome sequence of the Daphnia pathogen Octosporea bayeri : insights into the gene content of a large microsporidian genome and a model for host-parasite interactions
Corradi, Nicolas; Haag, Karen Luisa; Pombert, Jean-François; Ebert, Dieter; Keeling, Patrick J. (2009) [Journal article]Background: The highly compacted 2.9-Mb genome of Encephalitozoon cuniculi placed the microsporidia in the spotlight, encoding a mere 2,000 proteins and a highly reduced suite of biochemical pathways. This extreme level ... -
Echinococcus granulosus sensu lato and Taenia hydatigena in pig in southern Brazil
Monteiro, Danieli Urach; Botton, Sonia; Tonin, Alexandre Alberto; Haag, Karen Luisa; Musskopf, Germano; Azevedo, Maria Isabel de; Weiblen, Carla; Ribeiro, Tatiana Correa; La Rue, Mario Luiz de (2015) [Journal article]This study aimed to identify the parasitical etiologic agents of visceral cysts in pigs from the central/northern region of Rio Grande do Sul State, Brazil. Fifty-eight cysts were found in livers during veterinary inspection ... -
Holobionts and their hologenomes: evolution with mixed modes of inheritance
Haag, Karen Luisa (2018) [Journal article]Symbioses are ubiquitous and have played an influential role in the evolution of life on Earth. Genomic studies are now revealing a huge diversity of associations among hosts and their microbiotas, allowing us to characterize ... -
Isolation and characterization of microsatellites from the tapeworm Echinococcus granulosus
Bartholomei-Santos, Marlise Ladvocat; Heinzelmann, Larissa Schemes; Oliveira, R. P.; Chemale, Gustavo; Gutierrez, Ariana M.; Kamenetzky, Laura; Haag, Karen Luisa; Zaha, Arnaldo (2003) [Journal article]The Echinococcus granulosus genome was searched for microsatellites using 8 different repeated oligonucleotides as probes (GT15, CT15, AT15, CG15, CAT10, CAA10, CGG10 and CATA10). Southern blot experiments revealed that ... -
Reduced genetic variability within coding and non-coding regions of the echinococcus multilocularis genome
Haag, Karen Luisa; Zaha, Arnaldo; Araujo, Aldo Mellender de; Gottstein, Bruno (1997) [Journal article]Echinococcus multilocularis, a vulpine intestinal tapeworm, is the causative agent of alveolar echinococosis in humans, one of the most severe and lethal parasitic infections in man. To date, there is very little knowledge ... -
Redundancy and recombination in the Echinococcus AgB multigene family : is there any similarity with protozoan contigency genes?
Haag, Karen Luisa; Gottstein, Bruno; Muller, Norbert; Schnorr, André; Ayala, Francisco J. (2006) [Journal article]Numerous genetic variants of the Echinococcus antigen B (AgB) are encountered within a single metacestode. This could be a reflection of gene redundancy or the result of a somatic hypermutation process. We evaluate the ... -
Selection, recombination and history in a parasitic flatworm (Echinococcus) inferred from nucleotide sequences
Haag, Karen Luisa; Araujo, Aldo Mellender de; Gottstein, Bruno; Zaha, Arnaldo (1998) [Journal article] -
The EG95 antigen of Echinococcus spp. contains positively selected amino acids, which may influence host specificity and vaccine efficacy
Haag, Karen Luisa; Gottstein, Bruno; Ayala, Francisco J. (2009) [Journal article]Echinococcosis is a worldwide zoonotic parasitic disease of humans and various herbivorous domestic animals (intermediate hosts) transmitted by the contact with wild and domestic carnivores (definitive hosts), mainly foxes ...
