Understanding the ecological processes that are involved in transmission of zoonotic pathogens by small mammals may aid adequate and effective management measures. Few attempts have been made to analyze aspects influence pathogen infection livestock production systems. We describe with Leptospira spp., Brucella Trichinella spp. Cysticercus fasciolaris assess related intrinsic extrinsic factors systems central Argentina at mammal community, population individual levels.
Abstract Many ectoparasite species serve as vectors for bacteria that are significant to both public and animal health, with wild, domestic synanthropic mammals acting reservoirs. However, limited information exists on the circulation incidence of these in Argentina. We examined diversity, prevalence abundance ectoparasites, along presence Rickettsia spp., Didelphis albiventris Lund (Didelphimorphia, Didelphidae) within a rural landscape Pampas region, also analysed variations populations...
Antimicrobial resistance has become a significant global issue impacting humans, animals, and the environment. Currently, focus of concern shifted to environment, which can act as reservoir significantly contribute spread genes. This study aimed elucidate potential transmission mcr-1, confers colistin resistance, among Escherichia coli isolates from pigs, dairy cattle, co-habiting rodents. In March 2018, 30 fecal samples were collected three pig farms one mixed cattle farm, 31 cecal contents...
Summary Objective To determine the prevalence of infection with hantaviruses in wild Rattus norvegicus and R. rattus populations areas Buenos Aires city. Methods Norway rats black were trapped from 2003 to 2005 at 10 sites throughout Blood samples for serological analysis collected by cardiac puncture all individuals captured tested enzyme‐linked immunosorbent assay Seoul hantavirus‐ Andes virus‐specific IgG antibodies. Results Hantavirus seroprevalence was 11.9% ( n = 151), varying between...
Context Life-history theory attempts to explain the way in which an organism is adapted its environment as well explaining differences life-history strategies among and within species. Aims The aim of this paper was compare traits Norway rat house mouse living different habitats geographic regions so find patterns related environmental characteristics on basis published ecological studies conducted before 2011. Methods environments where rodent populations lived were characterised according...
Abstract Small rodent communities and their distribution among habitats (sheds, perimeters interphases) were seasonally sampled over 2 years on 30 poultry farms. Interphases present when sheds close to (in 16 of farms). The exotic Mus musculus four sylvan species: Calomys laucha, Akodon azarae, Oligoryzomys flavescens musculinus captured. was more abundant in A. azarae interphases perimeters. other species did not differ habitats. abundance vary through the year, whereas greater autumn –...
The aim of this research was to compare the abundance, growth, age structure and reproductive patterns Rattus norvegicus Mus musculus populations a shanty town parkland in city Buenos Aires, Argentina. Live trapping rodents conducted each area every 2 months, from September 2006 August 2007. Abundance R. M. significantly higher than parkland. both species showed significant differences between sessions study sites. Both peak abundance summer also autumn town. Age differed summer–autumn...
Abstract Life history characteristics are influenced by both biotic and abiotic factors of the environment. The aim this study was to compare life strategies
This study aimed to analyse changes in the spatial distribution of Lutzomyia longipalpis Posadas, an urban area located northeastern Argentina. Data were obtained during summer 2007 and 2009 through two entomological surveys peridomiciles distributed around city. The abundance pattern for was computed compared with previous 2007, when first human visceral leishmaniasis cases reported Vector also examined relation micro macrohabitat characteristics. In 2009, Lu. among 41.5% 31% households...
Abstract Background In South America, cutaneous leishmaniasis (CL) and visceral (VL) are emerging diseases, expanding in the border area of Argentina, Brazil Paraguay. Outbreaks CL were reported since 1990s, with Nyssomyia whitmani as main vector this region. Regarding VL, urban reports started 2010 Lutzomyia longipalpis vector. The aim study was to evaluate environmental determinants related vectors leishmaniasis, contribute prevention control response emergence VL Argentina-Brazil-Paraguay...
Abstract 1. Seasonal variations in rodent infestations were studied at poultry farms central Argentina as well the environmental factors associated with farms. 2. During summer and winter of 1998 infestation was monitored 10 by means tracking stations, 21 variables selected that a priori could be related extent infestation. 3. There higher than summer. 4. Species detected sightings included Akodon azarae, Calomys spp. (C. laucha possibly C. musculinus) Mus musculus. 5. In summer, positively...
We studied hantavirus seroprevalence and virus variability in rodent populations Diego Gaynor, northwest of Buenos Aires province, Argentina. Rodent samplings were conducted railroads cropfield borders March July 1999, September December 2000, 2001. Antibody detection was performed by an enzyme link immunosorbent assay (ELISA), using the recombinant nucleoprotein Andes (AND) as antigen. Tissue samples taken from positive antibody individuals order to confirm presence genomic material...
Abstract The aim of this work was to study the distribution Phlebotominae (Diptera: Psycodidade) abundance in time and space an area northeastern Argentina with vector transmission visceral tegumentary leishmaniasis. For this, 51 households were selected using a ‘worst scenario’ criterion where one light trap set during two consecutive nights peridomiciles transitions between four seasons, environment surveyed simultaneously. relationships phlebotomine assemblage structure most abundant...
Abstract BACKGROUND Rodent species are common in livestock production systems, and some of them considered serious pests because the sanitary problems economic losses they cause. Information about microhabitat selection by rodent systems is necessary for understanding requirements to contribute effective prevention development control measures pest species. In this work we study that inhabit pig dairy farms central Argentina. trapping was conducted over three years (2008–2011) on 18 farms,...
Abstract Rattus norvegicus and rattus are commensal pest rodents, considered reservoirs vectors of zoonotic pathogens. In livestock farms, the wide use antimicrobials their release into environment lead to high long‐term residual concentrations, which may in turn occurrence antimicrobial resistance (AMR). Farm environments serve as AMR sources, resulting transmission antimicrobial‐resistant bacteria genes origin wildlife. This study aimed analyse profile enterobacteria carrying determinants...
