Babesia bovis biological clones and the inter-strain allelic diversity of the Bv80 gene support subpopulation selection as a mechanism involved in the attenuation of two virulent isolates
Baravalle, María Eugenia; Thompson, Carolina Soledad; Valentini, Beatriz Susana; Ferreira, Mariano B.; Torioni, Susana Marta; Florin-Christensen, Mónica; Echaide, Ignacio Eduardo (Elsevier, 2012-12-21)The virulence phenotype of Babesia bovis subpopulations was evaluated using biological clones derived from the high-virulence BboS2P and the low-virulence BboR1A strain and two original virulent isolates, BboL15 and BboL17, ... -

Carletti, Tamara; Mesplet, Maria; Mira, Anabela; Weir, William; Shiels, Brian; Gonzalez Oliva, Abel; Schnittger, Leonhard; Florin-Christensen, Mónica; Barreto, Carmo (2016)Babesia ovis, a tick-transmitted intraerythrocytic protozoan parasite, causes severe infections in small ruminants from Southern Europe, Middle East, and Northern Africa. With the aim of finding potential targets for the ... -
Cysteine proteinase C1A paralog profiles correspond with phylogenetic lineages of pathogenic piroplasmids
Ascencio, Mariano E.; Florin-Christensen, Mónica; Mamoun, Choukri B.; Weir, William; Shiels, Brian; Schnittger, Leonhard (MDPI, 2018-04)Piroplasmid parasites comprising of Babesia, Theileria, and Cytauxzoon are transmitted by ticks to farm and pet animals and have a significant impact on livestock industries and animal health in tropical and subtropical ... -
Evidence for extensive genetic diversity and substructuring of the Babesia bovis metapopulation
Flores, Daniela; Minichiello, Y.; Araujo, Flabio Ribeiro de; Shkap, V.; Benitez, Daniel Francisco; Echaide, Ignacio Eduardo; Rolls, P.; Mosqueda, J.; Pacheco, Maria Gabriela; Petterson, Maria Elizabeth; Florin-Christensen, Mónica; Schnittger, Leonhard (2013-11)Babesia bovis is a tick-transmitted haemoprotozoan and a causative agent of bovine babesiosis, a cattle disease that causes significant economic loss in tropical and subtropical regions. A panel of nineteen micro- and ... -
Mitigated clinical disease in water buffaloes experimentally infected with Babesia bovis
Benitez, Daniel Francisco; Mesplet, Maria; Echaide, Ignacio Eduardo; Torioni, Susana Marta; Schnittger, Leonhard; Florin-Christensen, Mónica (2018-07)Water buffaloes (Bubalus bubalis) are raised in tropical and subtropical regions of the world, and act as hosts of Babesia bovis parasites and the tick vector Rhipicephalus microplus. As no clinical cases of B. bovis-infection ... -
Molecular and serological detection of Babesia bovis- and Babesia bigemina-infection in bovines and water buffaloes raised jointly in an endemic field
Romero-Salas, Dora; Mira, Anabela; Mosqueda, Juan; García-Vázquez, Zeferino; Hidalgo-Ruiz, Mario; Ortiz Vela, Noot Aditya; Perez de Leóne, Adalberto Angel; Florin-Christensen, Monica; Schnittger, Leonhard (2016-01)Babesia bovis and Babesia bigemina are causative agents of bovine babesiosis, a tick-borne disease of cattle in tropical and subtropical regions. Babesia spp. infection adversely affects cattle health and can be fatal ... -
Molecular characterization of Cryptosporidium isolates from calves in Argentina
Tomazic, Mariela Luján; Maidana, Jimena; Dominguez, Mariana Gabriela; Louge Uriarte, Enrique Leopoldo; Galarza, Roxana Ivon; Garro, Carlos Javier; Florin-Christensen, Monica; Schnittger, Leonhard (2013-12)Cryptosporidiosis is responsible for significant fatalities of neonatal calves, resulting in substantial economic loss in dairy farming in several countries. Additionally, the high shedding of environmentally resistant ... -
Molecular detection of Sarcocystis aucheniae in the blood of llamas from Argentina
Decker Franco, Cecilia; Romero, Sandra Raquel; Carletti, Tamara; Schnittger, Leonhard; Florin-Christensen, Monica; Martin, Mara Edith (2016-09)Sarcocystis aucheniae are apicomplexan protozoa that infect South American camelids (SACs), giving rise to macroscopic cysts similar to rice grains in skeletal muscles. Visual detection of macrocysts in slaughtered animals ... -
Molecular identification of Sarcocystis aucheniae as the macrocyst-forming parasite of llamas
Carletti, Tamara; Martin, Mara; Romero, Sandra Raquel; Morrison, David A.; Marcoppido, Gisela Ariana; Florin-Christensen, Monica; Schnittger, Leonhard (2013-12)The domestic South American camelids (SACs), llama (Lama glama) and alpaca (Lama paco), are frequently found to be infected with Sarcocystis parasites. Infections give rise in skeletal muscle to macroscopic cysts (1–5 mm ... -
Reclassification of Theileria annae as Babesia vulpes sp. nov.
Baneth, Gad; Florin-Christensen, Mónica; Cardoso, Luís; Schnittger, Leonhard (2015-04)Background: Theileria annae is a tick-transmitted small piroplasmid that infects dogs and foxes in North America and Europe. Due to disagreement on its placement in the Theileria or Babesia genera, several synonyms have ... -
