Development, validation and field evaluation of an indirect ELISA for the detection of antibodies against Brucella abortus in bulk and individual milk samples in dairy cattle
(Elsevier, 2022-11)Brucellosis is an abortigenic and zoonotic disease. In cattle, it is mainly caused by Brucella abortus. The disease is endemic in low- and middle-income countries, being considered a neglected zoonotic disease. In these ... -
Different lines of evidence used to delimit species in ticks : a study of the South American populations of Amblyomma parvum (Acari: Ixodidae)

Discovering ancestors and connecting relatives in large genomic databases
(Elsevier; American Dairy Science Association, 2020-02)Genomic evaluation has improved both plant and animal breeding by allowing more accurate estimation of an individual's genetic potential. Because often only a small proportion of the population to be evaluated has been ... -
Disposal of veterinary supplies used in rural areas from Santa Fe province, Argentina
(Facultad de Agronomía, Universidad de Buenos Aires, 2023-12)The disposal of waste from clinical work may impacts on the environment, animal and public health. Nevertheless, few studies have acknowledged the extent of unproper management of used syringes, needles, medicine containers ... -

Distribution and genetic variation of Amblyomma triste (Acari: Ixodidae) in Argentina
(2013-09)A study was conducted to investigate the distribution of Amblyomma triste in Argentina under the hypothesis that this tick prevails in riparian localities along the Paraná River and adjacent humid environments from 34°30′ ... -
Distribution and prevalence of Nosema apis and N. ceranae in temperate and subtropical eco-regions of Argentina
(2016-11)A total of 361 colonies from 59 apiaries located in two temperate and three subtropical eco-regions were examined during the post-harvest period to determine distribution and prevalence of Nosema spp. Apiaries from subtropical ... -
Divergent environmental preferences and areas of sympatry of tick species in the Amblyomma cajennense complex (Ixodidae)
(2014-12)Four species of Neotropical ticks, Amblyomma mixtum, Amblyomma cajennense, Amblyomma tonelliae and Amblyomma sculptum (formerly included in the catch-all name A. cajennense), have an allopatric distribution in much of their ... -

Diversity and biological traits of bees visiting flowers of Cucurbita maxima var. zapallito differ between biodiversity-based and conventional management practices
(Springer Nature, 2024-01)Low diversity of pollinators and the modified composition of functional groups of bees have been proposed as the causes of pollination deficiency in cultivated Cucurbitaceae species. Functional groups of bees are determined ... -
Do parapatric populations of the ticks Amblyomma tonelliae Nava, Beati & Labruna, 2014 and Amblyomma sculptum Berlese, 1888 (Acari: Ixodidae) hybridize?
(Royal Entomological Society, 2023-02-02)This work aimed to determine if the tick species, Amblyomma sculptum and Amblyomma tonelliae, hybridize along their contact zones in Argentina. Free-living adults and nymphs of A. sculptum and A. tonelliae were collected ... -
Does parity order or cow antibody level influence the humoral immunity of calves for cattle anaplasmosis?
(Springer, 2024-02)Anaplasmosis is a widely distributed vector-borne disease of cattle caused by the bacteria Anaplasma marginale, which may lead to severe losses in beef and dairy cattle production. Anecdotal information among farmers ... -
