Characterization of Escherichia coli carrying mcr-1-plasmids recovered from food animals from Argentina
(Frontiers Media, 2019-03)In this study, we found mcr-1.1 and mcr-1.5 genes carried by IncI2 plasmids in a subset of Escherichia coli isolates recovered from commercial broiler farms in Argentina. The comparative analysis of the sequences of these ... -
Co-composting of poultry manure with other agricultural wastes: process performance and compost horticultural use
(2015-01)The aim of this work was to evaluate the composting process of poultry manure mixed with other complementary organic wastes. Two mixtures (treatment 1 and 2) were prepared with corn bare cobs, sawdust, shavings and manure. ... -
Development of phytotoxicity indexes and their correlation with ecotoxicological, stability and physicochemical parameters during passive composting of poultry manure
(2016-08)Both raw and composted poultry manure is applied as soil amendment. The aims of this study were: (1) to develop phytotoxicity indexes for organic wastes and composts, and (2) to assess the correlation among phytotoxicity ... -
Development of RT-qPCR assays for the specific identification of two major genotypes of avian infectious bronchitis virus
(2016)Infectious bronchitis virus (Gammacoronavirus, Coronaviridae) is a genetically variable RNA virus (27.6kb) that causes one of the most persistent respiratory disease in poultry. The virus is classified in genotypes with ... -
Efficacy of chestnut and quebracho wood extracts to control Salmonella in poultry
(Wiley, 2021-07)Aims: The study was aimed to evaluate the antibacterial activity and efficacy of chestnut and quebracho wood extracts against Salmonella by in vitro assays and in vivo trials. Methods and results: The extracts showed ... -
Estudio de la patogenia del Virus de Influenza Aviar de Baja Patogenicidad en aves de corral inmunosuprimidas por la infección con el Virus de la Anemia Infecciosa Aviar
(Universidad de Buenos Aires, 2014-12)La Influenza Aviar es considerada una zoonosis con potencial pandémico. El agente etiológico responsable de esta enfermedad es el Virus de Influenza A, cuyo reservorio natural son las aves silvestres acuáticas. En ellas, ... -
Evasion of maternal antibody protection by an IBDV Argentine variant
(Elsevier, 2024-03)Infectious bursal disease (IBD) is a viral disease that affects the ability of chickens to produce humoral immune responses. One way to prevent the disease is the passage of maternally derived antibodies (MDA) from dams ... -
How did antibiotic growth promoters increase growth and feed efficiency in poultry?
(Elsevier, 2024-02)It has been hypothesized that reducing the bioenergetic costs of gut inflammation as an explanation for the effect of antibiotic growth promoters (AGPs) on animal efficiency, framing some observations but not explaining ... -
Molecular characterization and antimicrobial resistance profiles of Salmonella Heidelberg isolates from poultry
(Wiley, 2021-02)In the last 10 years, Salmonella Heidelberg has been extensively isolated from poultry in several countries. In this context, molecular characterization is essential to understand whether the strains have entered the farms ... -
Optimización de la digestión anaeróbica del guano de aves ponedoras
(Instituto de Investigación e Ingeniería Ambiental, Universidad Nacional de San Martín, 2019)La producción avícola de ponedoras en sistemas intensificados se ha incrementado exponencialmente en los últimos años, conduciendo a la generación de grandes volúmenes de residuos que si no son gestionados adecuadamente ... -
Performance of semi-continuous anaerobic co-digestion of poultry manure with fruit and vegetable waste and analysis of digestate quality: A bench scale study
(2018)Poultry manure (PM) can contain ammonium and ammonia nitrogen, which may inhibit the anaerobic process. The aim of this work was to evaluate the performance of anaerobic digestion of PM co-digested with fruit and vegetable ... -
Phytochemicals as antibiotic alternatives to promote growth and enhance host health
(BioMed Central, 2018-07)There are heightened concerns globally on emerging drug-resistant superbugs and the lack of new antibiotics for treating human and animal diseases. For the agricultural industry, there is an urgent need to develop strategies ... -
Simultaneous carriage of mcr-1 and other antimicrobial resistance determinants in Escherichia coli from poultry
(Frontiers Media, 2018-07)The use of antimicrobial growth promoters (AGPs) in sub-therapeutic doses for long periods promotes the selection of resistant microorganisms and the subsequent risk of spreading this resistance to the human population and ... -
South American H4N2 influenza A virus improved replication in chicken trachea after low number of passages
(Frontiers Media, 2023-05)Introduction of influenza A viruses (FLUAV) into poultry from waterfowl is frequent, producing economic burden and increasing the probability of human infections. We have previously described the presence of FLUAV in wild ... -
Temporal variation of physico-chemical, microbiological, and parasitological properties of poultry manure from two egg production systems
(Springer, 2020-03)Egg production has increased worldwide and, consequently, there is a large volume of poultry manure generated. The principal egg production systems are the caged ones, namely the conventional and the automated. The aim of ... -
The role of farm environment and management in shaping the gut microbiota of poultry
(Springer Nature, 2022-01)Gut microbiota of poultry assembles from environmental sources mainly determined by farm management decisions such as feed composition, litter handling and sanitation practices, or the use of different feed additives. In ... -
