Microbiological quality of fresh ground beef and detection of pathogens in environmental samples taken from butcher shops in the city of Tandil, Buenos Aires Province, Argentina
Rev Argent Microbiol. 2021 Sep 20:S0325-7541(21)00075-4. doi: 10.1016/j.ram.2021.04.003. Online ahead of print.ABSTRACTThe aim of this work was to evaluate the hygienic-sanitary conditions of butcher shops in Tandil, Buenos Aires Province, by estimating the risk based on good manufacturing and hygiene practices, through surveys of the establishments. The analysis was performed using a scale of 1-100, and classifying them as high risk (0-40), moderate risk (41-70) or low risk (71-100). The presence of Salmonella spp., Staphylococcus aureus and Shiga toxin-producing Escherichia coli (STEC) from both, ground beef and environm...

Evaluation of interventions during the COVID-19 pandemic: development of a model based on subpopulations with different contact rates
Rev Argent Microbiol. 2021 Jul 24:S0325-7541(21)00078-X. doi: 10.1016/j.ram.2021.04.004. Online ahead of print.ABSTRACTAlthough multiple attempts have been made to mathematically model the current epidemic of SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), few models have been conceived as accessible interactive tools for users from various backgrounds. The goal of this study was to develop a model that took into account the heterogeneity in contact rates within the population and to implement it in an accessible application allowing to estimate the impact of possible interventions based on availabl...

Tegumentary leishmaniasis and sandflies in Colonia Santa Rosa locality in northern Argentina
Rev Argent Microbiol. 2021 Sep 6:S0325-7541(21)00077-8. doi: 10.1016/j.ram.2021.06.002. Online ahead of print.ABSTRACTTegumentary leishmaniasis (TL) is caused by parasites of the genus Leishmania and transmitted by the sandfly species, insects belonging to the order Diptera, family Psychodidae. Historically, the most endemic area of TL in Argentina has been the northern region. The aim of this work was to analyze the presence and temporal variation of TL cases reported between 1985 and 2019 in Colonia Santa Rosa locality, northern Argentina. Furthermore, its clinical forms were characterized and sandflies were captured. Pa...

Detection by multiplex PCR of Mycoplasma species associated with dairy cattle in Argentina
The objectives of this study were to develop a multiplex PCR for identifying M.bovis and M.canadense and to describe the frequency of Mycoplasma spp. isolated from clinical samples submitted to a diagnostic laboratory. Of a total of 1548 samples from intramammary infections, bulk tank milk and biological fluids, 38 Mycoplasma isolates were obtained. M. bovis, M. canadense, M.californicum and M.leachii were detected by using two multiplex PCRs, confirming their presence in clinical conditions in dairy cattle. The techniques used in the present study can be useful to broaden the knowledge about Mycoplasma infections in cattl...

Campylobacter fetus releases S-layered and immunoreactive outer membrane vesicles
Rev Argent Microbiol. 2021 Aug 16:S0325-7541(21)00076-6. doi: 10.1016/j.ram.2021.06.001. Online ahead of print.ABSTRACTThe study of outer membrane vesicles (OMVs) became relevant because of their probable important role in the transfer of virulence factors to host cells. Campylobacter fetus is mainly a mammal pathogen whose virulence characterization is still limited. The aim of this study was to evaluate and to characterize the secretion of OMVs in this bacterium. By transmission electron microscopy, we confirmed the production of OMVs in all the strains assayed. Purified OMVs showed a spherical shape and variable size, a...

The drop plate method as an alternative for Azospirillum spp viable cell enumeration within the consensus protocol of the REDCAI network
Rev Argent Microbiol. 2021 Jul 7:S0325-7541(21)00056-0. doi: 10.1016/j.ram.2021.05.002. Online ahead of print.ABSTRACTQuality evaluation of commercial inoculants is essential to warrant an adequate crop response to inoculation within a biosecurity framework. In this sense, this work is aimed at standardizing and validating the drop plate method for the enumeration of Azospirillum viable cells as an alternative to the spread plate technique, which is currently proposed in the consensus protocol of the REDCAI network. Between 14 and 25 private and public laboratories participated in three independent trials. We obtained cons...
