Porcine haemoplasmosis caused by Mycoplasma suis affects the global pig industry with significant economic losses. The main transmission route of M. suis is through the blood and some haematophagous arthropods, like flies and mosquitoes, could be the vectors to this pathogen. However, the presence of M. suis in pig haematophagous ectoparasites in n...

In Argentina, domestic pigs (Sus scrofa Linnaeus 1758) were introduced during the first Buenos Aires foundation, in the year 1536. Their provenance was mainly from the Iberian Peninsula, the Canary Islands and Cape Verde. In 1541 those pigs were released and, consequently, the first feral populations were originated. Thereafter, the species propaga...

Porcine Stress Syndrome (PSS) is a disorder codified by the ryanodine receptor 1 gene (RYR1) and affects both animal welfare and the quality of the meat product. As a consequence, individuals with this syndrome generate great worldwide economic losses in the porcine industry. In Argentina, the Buenos Aires Province is the most involved on this acti...

Domestic dog (Canis lupus familiaris) plays a vital role in transmitting zoonotic ectoparasites and vector-borne pathogens, often being an important source of pathogens in spill over and spillback processes between domestic and wild animals. The aim of this study was analyzing the diversity and prevalence of ectoparasites and their associated bacte...

Hybridization between individuals of different subspecies play an important role in evolutionary processes. These crosses in exotic species have been reported to generate effects such as alterations in the local gene pool, enhance genetic variability, morphological and coat colour changes, which gives it a greater adaptive potential and, thus an in...

Vector-borne diseases account for nearly 20% of all globally recognised infectious diseases. Within the spectrum of flea-borne pathogens, Bartonella and Rickettsia bacteria are prominent, contributing to the emergence and resurgence of diseases on a global scale. This study investigates the presence of species of Bartonella and Rickettsia harboured...

The Coastal Creole pigs in Argentina are predominantly found in the wild and can trace their lineage directly back to the Iberian breeds introduced by Spanish colonizers. They currently stand as the sole Creole breed in the country recognized by the FAO. However, there exists a dearth of studies assessing their genetic potential within the swine in...

The wild boar (Sus scrofa) was introduced to Patagonia in the early 20th century through multiple independent events in Junín de los Andes, the Huemul Peninsula, and Victoria Island (Neuquén Province). Despite uncertainties surrounding their origin, questions persist regarding the extent of hybridization between these populations and domestic or fe...

The puma (Puma concolor Linnaeus, 1771) is the top predator with the widest distribution in America. Since the establishment of European settlers on the American continent, puma populations have experienced significant contractions and reductions in their original distribution. In Argentina, the management of the conflict between humans and pumas (...

Argentina is a small player in the global pork market, contributing only 0.7% of the total production. With increasing global demand for meat, there is an opportunity for countries with an agricultural profile to grow their pork production. However, there is a need to understand the current state of the pork production sector in all aspects to info...

El leucismo se define como la falta total o parcial de pigmentación en el cuerpo, exceptuando las partes blandas. Este desorden podría afectar la supervivencia y el éxito reproductivo del animal. En este trabajo se reporta el primer caso de leucismo en Eptesicus furinalis y Tadarida brasiliensis en la provincia de San Luis, Argentina. Para cada esp...

In Argentina, wild pigs (Sus scrofa) are represented by wild boars and feral pigs. These populations inhabit a wide territory due to natural dispersion and human translocation. Previous studies in other countries have detected crossbreeding between the different morphotypes, even with domestic pigs. This crossing can lead to introgression of improv...

Rickettsioses are distributed among a variety of hematophagous arthropods, and represent an emergent threat. The presence of rickettsial bacteria in ectoparasites collected from pigs from Argentina is still unknown. This study investigated the presence and identity of Rickettsia spp. in fleas, Pulex irritans, and sucking lice, Haematopinus suis, of...

Las bacterias del género Rickettsia, transmitidas por ectoparásitos, son agentes causales de diversas enfermedades infecciosas zoonóticas emergentes. En Argentina, el ectoparásito más frecuente y abundante en cerdos domésticos (Sus scrofa) es el piojo Haematopinus suis, registrándose también otros ectoparásitos hematófagos como pulgas y garrapatas....

En los cerdos (Sus scrofa), el ectoparásito más frecuente y abundante es el piojo Haematopinus suis. Este parásito es uno de los principales problemas sanitarios en la producción porcina y constituye una importante vía de transmisión de organismos patógenos, como virus y bacterias. En Argentina no existen estudios sobre la presencia de bacterias pa...

The Eurasian wild boar (Sus scrofa Linnaeus, 1758) was introduced into Argentina at the beginning of the twentieth century when individuals from Europe were taken to La Pampa province for hunting purposes. Starting from there, a dispersal process began due to the invasive characteristics of the species and to human-mediated translocations. The main...

Haematopinus suis, es el piojo de Sus scrofa domestica, y es el ectoparásito más frecuente del ganado porcino, causando importantes pérdidas económicas que derivan de la deficiencia en el rendimiento del ganado. En nuestro país, son escasos los estudios sistemáticos y genéticos en este piojo, de esto modo se desconoce la variabilidad morfológica y...

La pediculosis provocada por Haematopinus suis es uno de los problemas sanitarios más frecuentes en la producción porcina. El objetivo del presente trabajo fue realizar un estudio preliminar de las características morfológicas y moleculares de H. suis en la provincia de Buenos Aires, y detectar la presencia de los patógenos Mycoplasma suis y Ricket...

Gene therapy is a treatment that offers an alternative to pharmacological, surgical and conventional approaches that is being developed at an experimental and clinical level. In this review, apart from mentioning advances and presenting an overview of the subject in the biomedical field, our intention is to extend the concept of DNA. DNA is the sto...
