Leishmaniasis in the Argentine Republic: Temporal and geographical distribution from 2013 to 2017
(Oficina Editorial de la Universidad Médica de Hainan, 2019)To assess the temporal and geographical distribution of confirmed cases of cutaneous, mucocutaneous and visceral leishmaniasis in the Argentine Republic from 2013 to 2017. Methods: A retrospective study was carried out using data collected from the Integrated Surveillance Bulletin database of the National System of Health Surveillance. Confirmed cases of cutaneous, mucocutaneous and visceral leishmaniasis up to the 52nd epidemiological week of each year was included. In the 5 years period, 1 295 confirmed leishmaniasis cases were reported in the Argentine Republic. One thousand twenty-eight (1 ... -

Pseudobutyrivibrio xylanivorans adhesion to epithelial cells
(Comité editorial Anaerobe Journal, 2019-01-05)The ruminal bacteria Pseudobutyrivibrio xylanivorans strain 2 (P. xylanivorans 2), that mediates the digestion of plant fiber, is considered an attractive candidate for probiotics. Adherence to the epithelium of the digestive tract of the host is one of the major requirements for probiotics. In this study, we assessed the adhesion of P. xylanivorans 2 to SW480 cells and characterized this process utilizing multiple microscopy approaches. Our results indicate that a multiplicity of infection of 200 CFU/cell allows the highest bacteria to cell binding ratio, with a lower percentage of ... -
Plasma Cholinesterase Activity in Wild Birds from Undisturbed Woodlands in the Central Monte Desert
(2019-04-30)Plasma cholinesterase activity is a biomarker sensitive to the effect of organophosphate and carbamate pesticides, and its enzymatic levels have been previously unknown for most of the wild birds analyzed in the present study. Our objectives were to establish plasma acetylcholinesterase levels in songbirds of 2 undisturbed sites in the central Monte Desert (Argentina). We also examined the influence on cholinesterase activity of age, sex, body condition, feeding and migratory habits, and species. One hundred and sixty‐five wild birds belonging to 26 species were studied. The values obtained for ... -

Enfermedades que pueden transmitirnos nuestras mascotas
(2019-08-13)Reportaje de Canal 9 Televida, Mendoza al Dr. Roberto Mera y Sierra. En estos momentos hay una emergencia mundial por la mordedura de garrapatas en humanos. En Mendoza y en las ciudades también se ha visto un crecimiento de la hidatidosis, una enfermedad provocada por la materia fecal del animal, entre otras. -
Sustituto cárnico a base de cereales y legumbres de alto valor biológico.
(Comité editor libro de resúmenes CYTAL 2019, 2019-10-20)Las legumbres poseen un buen perfil nutricional, aportan hidratos de carbono complejos, fibra sobre todo insoluble y tienen un buen contenido de proteínas y grasas poliinsaturadas, pero su consumo en Argentina es muy bajo. Son el pilar de las dietas vegetarianas/veganas, ya que en este tipo de alimentación no se incluyen proteínas de alto valor biológico y a través de éstos, es posible incorporar ese nutriente carente de forma completa. El objetivo principal de este trabajo fue elaborar un sustituto cárnico a base de cereales- legumbres que sea completo a nivel proteico, dar una alternativa ... -
Evaluation of the genotoxic potential of cypermethrin, chlorpyrifos and their subsequent mixture, on cultured bovine lymphocytes
(Comité editorial Chemosphere Journal, 2019-11-09)Cypermethrin (CYP) and chlorpyrifos (CPF) are insecticides/parasiticides used in the production of fruits, vegetables and beef cattle. These substances or their metabolites are frequently reported as residues in food, whose consumption in a diet implies a genotoxic risk. The potential for chronic toxicity of CYP and CPF is unclear, and only a few genotoxicological evaluations based on their mixture have been performed. The aim of this study was to evaluate the genotoxic potential of CYP, CPF and CYP þ CPF in five concentrations, from 5.9 to 175 mg/mL, on bovine lymphocytes. By means of the ... -
Effect of progesterone and first evidence about allopregnanolone action on the progression of epithelial human ovarian cancer cell lines
(Comité editorial Journal of Steroid Biochemistry and Molecular Biology, 2020-02)Ovarian carcinoma is one of the most common cause of death by gynecologic cancer. Several epidemiological and in vitro studies have shown controversial data about progesterone effects in ovarian cancer. Progesterone can be converted in its active metabolite, allopregnanolone, its effects in ovarian cancer are still unknown. Previously, we demonstrated that allopregnanolone modifies ovarian morphophysiology, being able to alter critical process of tumor development such as proliferation, apoptosis and angiogenesis. Taking into account these antecedents, we investigated the effect of progesterone ... -
Biomonitoring of the hematological, biochemical and genotoxic effects of the mixture cypermethrin plus chlorpyrifos applications in bovines
(Science of the Total Environment Editorial, 2020-03-19)External antiparasitic agents applied in bovine production represent a risk to consumers of meat products, espe- cially if the conditions of their use are not strictly respected. The post-mortem control of residues in meat is an activity that must be updated and reinforced by the biomonitoring of live animals and the use of analytical tools to help identifying signs of early warning risks. The objective of the present study was to carry out a pre- slaughter biomonitoring approach in Aberdeen Angus cattle and crosses (n = 12) with the application of a com- mercial formulation of cypermethrin ... -

Epidemiological link between canine monocytic ehrlichiosis caused by Ehrlichia canis and the presence of Rhipicephalus sanguineus sensu stricto in Argentina
(Parasitology Research Editorial, 2021-01-08)In this work, we analyze data that support an epidemiological link between cases of canine monocytic ehrlichiosis (CME) by Ehrlichia canis and the presence of Rhipicephalus sanguineus sensu stricto as vector in an endemic area for this tick in Argentina. In a blood sample of a 1-year-old toy poodle with CME compatible clinical signs, which showed CME typical morulae in monocytes in Giemsa-stained blood smear, DNA of E. canis was detected by PCR. Further, DNA of E. canis was also detected in a female of R. sanguineus s.s. collected on the infected dog. Rhipicephalus sanguineus s.s. is the only ...
