Anaplasma marginale is an obligate intraerythrocytic bacterium of bovines, responsible for large economic losses worldwide. It mainly transmitted by Rhipicephalus (Boophilus) microplus ticks and, despite mounting evidence suggesting transovarial transmission, the occurrence this phenomenon remains controversial. We evaluated vector competence R. larvae vertically infected with A. to transmit a naïve bovine. A subgroup engorged female collected from marginale-positive animal was dissected and...
Bovine anaplasmosis is a disease caused by Anaplasma marginale, tick-borne bacterial pathogen with global distribution, primarily determined the range of its vector. In Argentina, Rhipicephalus microplus main species associated A. marginale transmission, even though this bacterium can also be mechanically transmitted. We studied complex infections (more than one variant) in naturally infected bovines from two different epidemiological contexts: region tick vector and tick-free region. area,...
Abstract Mortality events of marsh deer ( Blastocerus dichotomus ) have been historically described in the southern margins its geographical range. Few documented cases show how environmental changes and pathogens interact to trigger mortality scenarios reveal their causes. Here, using a participatory surveillance framework, we document most extensive event observed last three decades occurring Ibera ecoregion, Corrientes, Argentina. Local stakeholders monitored disease or mortality, upon...
Abstract Objective To evaluate the use of caudal vena cava collapsibility index (CVCCI) as a predictor fluid responsiveness in hospitalized, critically ill dogs with hemodynamic or tissue perfusion abnormalities. Design Retrospective observational study. Setting Private referral center. Animals Twenty‐seven ill, spontaneously breathing compromised hemodynamics hypoperfusion. Interventions None. Measurements and Main Results The electronic medical records were searched for admitted any cause,...
Abstract Background In an era of unprecedented socio-ecological changes, managing wildlife health demands high-quality data collection and the engagement local communities. Blastocerus dichotomus , largest South American deer, is Vulnerable to extinction mainly due habitat loss. Diseases have been recognised as a potential threat, winter mortality has historically described in marsh deer populations from Argentina. Field difficulties have, however, prevented in-depth studies their status....
Vector-borne pathogens are responsible for serious emerging diseases and have been widely described in wildlife. Ehrlichia chaffeensis causes the zoonotic "monocytic ehrlichiosis" humans, is transmitted by tick Amblyomma americanum its reservoir host white-tailed deer (Odocoileus virginianus) North America. Little known about native vectors involved transmission cycle South We report here detection of E. a study on marsh (Blastocerus dichotomus) mortality Argentina, different time periods...
Anaplasma marginale is a well-known cattle pathogen of tropical and subtropical world regions. Even though, this obligate intracellular bacterium has been reported in other host species different than bovine, it never documented Myrmecophaga tridactyla (giant anteater) or Hippocamelus antisense (taruca), which are two native endangered species. Samples from sick wild animals: (blood) (blood serum) were studied for the presence A. DNA through msp5 gene fragment amplification. Further...
Monitoring wildlife health is essential for understanding global disease patterns, particularly as vector-borne infections extend the geographic ranges and thereby hosts due to environmental shifts. Anaplasma marginale, primarily impacting cattle, has economic implications been found in diverse hosts, yet its presence capybaras (Hydrochoerus hydrochaeris), influential tick-borne pathogen spread, lacks comprehensive understanding. From 2015 2022, 14 were surveyed across two different areas of...
To evaluate the prognostic utility of quick Sepsis-related Organ Failure Assessment (qSOFA) for prediction in-hospital mortality and length hospitalization in dogs with pyometra.Retrospective cohort study from February 2013 to April 2019 SETTING: Tertiary referral hospital ANIMALS: Fifty-two referred confirmed diagnosis pyometra INTERVENTIONS: None MEASUREMENTS AND PRINCIPAL OUTCOMES: Sixty-five percent survived discharge. A cut-off score ≥2 qSOFA was associated (odds ratio 6.51 [95% CI:...
To evaluate a novel physiological approach for setting the tidal volume in mechanical ventilation according to inspiratory capacity, and determine if it results an appropriate gas exchange measurements healthy critically ill dogs.Twenty animals were included study assess expressed as percentage of capacity. For capacity measurement, ventilator was set follows: pressure control mode with 35cmH2O inspired zero end-expiratory 5 seconds. Subsequently, randomized into four groups ventilated...
Las rickettsiosis son enfermedades zoonóticas transmitidas por artrópodos vectores, que en Argentina presentan 2 escenarios epidemiológicos diferenciados. Uno, las yungas de Salta y Jujuy, involucra vectores pertenecientes al «complejo Amblyomma cajennense» (A. sculptum A. toneliae) a Rickettsia rickettsii como agente etiológico. En este escenario la forma clínica enfermedad se conoce fiebre manchada (FM) presenta con manifestaciones cutáneas sistémicas graves. El otro incluye zonas: una del...
Anaplasma marginale, a well-known cattle pathogen of tropical and subtropical world regions, has been previously molecularly characterized in giant anteater (Myrmecophaga tridactyla) from Corrientes, Argentina. Ticks or other hematophagous arthropod involved the wild transmission cycle remained unknown. The aim present study was to analyze simultaneous occurrence A. marginale blood samples ticks anteaters Corrientes order investigate if could be relevant among these mammals. Blood 50...
Streptococcus equi subsp. zooepidemicus (S. zooepidemicus) is part of the microbiota lower genital tract in horses and most isolated bacterium causing endometritis mares. The aim this study was to determine molecular diversity S. obtained from mares Buenos Aires province, Argentina. Thirty isolates uterus 2005 2017 were studied. MLST scheme applied order identify Argentinian genotypes clonal relationships patterns evolutionary descent identified using eBURST algorithm – goeBURST. Twenty six...
Abstract Bovine babesiosis is caused by the intraerythrocytic protozoans Babesia bovis and bigemina in tropical subtropical regions worldwide. The diagnosis of these tick-borne pathogens may represent a challenge due to low parasitaemias usually found persistent infections also acute cases. Additionally, correct determination epidemiological status herd key point for further diagnostic interpretations. In this regard, work, we review available tools suggest algorithms facing different...
