“…However, high humidity, close to saturation, is connected with infection periods due to an increase in the percentage of inoculum; and under these conditions auto multiplication of inoculum produces very high insect contamination, which strongly facilitates epizootic development of mycosis (Guglielmone et al 1997). On the other hand when the humidity is very low, the effectiveness of entomopathogenic fungi can be very limited (Lo & Chapman 1998).…”

“…Therefore, the 2 most plausible methods for R. (Boophilus) microplus to transmit A. marginale is by acquiring and transferring the organism to the developing ova and subsequent generation of larvae (Shimada et al 2004), or by transferring A. marginale between cattle hosts by male ticks (Kocan et al 1992). These methods of transmission appear to have a small contribution to the transmission capability of A. marginale by R. (Boophilus) microplus and transmission by means other than R. (Boophilus) microplus should be emphasized in cattle operations (Guglielmone et al 1997). …”

“…A su vez, el predominio de A. marginale y B. bovis aquí mencionado coincide también con lo descripto por Sarmiento y Zimmer (2010) para brotes ocurridos en la provincia de Corrientes durante un breve lapso (2009)(2010). Por otra parte, en la provincia de Santa Fe se informó una estacionalidad similar para brotes de anaplasmosis en rodeos de cría, pero no así en rodeos lecheros, donde ellos ocurrieron sin estacionalidad definida (Guglielmone et al, 1997). En nuestro estudio el número de casos en rodeos lecheros fue insuficiente para establecer patrones de estacionalidad.…”

“…Por su parte, A. marginale puede ser transmitido biológicamente por esta u otras garrapatas (Aguirre et al, 1994;Gaido et al, 1995) pero también en forma mecánica por dípteros hematófagos (géneros Tabanus, Stomoxys y varias especies de mosquitos) y de manera iatrogénica por fómites (Kocan et al, 2010). La distribución estacional de brotes de TPB en Argentina presenta similitudes entre diferentes regiones geográficas y con países vecinos (Guglielmone et al, 1997;Sarmiento y Zimmer, 2010;Begeres de Almeida et al, 2006;Solari et al, 2013). Aunque todos suelen mostrar una marcada variabilidad interanual, principalmente como resultado de factores medioambientales y de manejo que modulan la interacción entre vectores y bovinos (Nava et al, 2013).…”
