Comparative review of brucellosis in small domestic ruminants por Rossetti, Carlos Alberto, Maurizio, Estefanía, Rossi, Ursula Amaranta

“…Despite being species of the same bacterial genus, B. melitensis and B. ovis have extensive differences in their cultural and biochemical characteristics (smooth vs. rough colonial phases, serum and CO2 dependence for in vitro growth, carbohydrate metabolism), host preference (female goat and sheep vs. rams), the outcome of infection (abortion vs. epididymitis), and their zoonotic potential. …”

Epidemiology and effect of gastrointestinal nematodes on beef cattle from tropical Argentina por Suarez, Victor Humberto, Martinez, Gabriela Marcela, Micheloud, Juan Francisco, Viñabal, Alberto

“…The aim of this work was to study the epidemiology and the harmful effect of gastrointestinal nematodes (GINs) on beef cattle in the piedmont forest and grassland region of northwestern Argentina, between March 2015 and March 2016. Sixty weaned female calves were divided into three groups: STG—calves treated systematically with 200 mcg/kg moxidectin every 40–50 days; LTG—calves treated as usually locally implemented, with 200 mcg/kg ivermectin on May 4 and August 5; and UTG—calves not receiving treatment. …”

Toxicity on Orius insidiosus (Hemiptera: Anthocoridae) and Tupiocoris cucurbitaceus (Hemiptera: Miridae) of homemade botanical and mineral pesticides used in agroecological systems por Andorno, Andrea Veronica, Lopez, Silvia Noemi, Viscarret, Mariana Mabel, Carrizo, Paola Irene, Cagnotti, Cynthia Lorena

“…Chili fruit extract affected the survival of adults of O. insidiosus and onion infusion produced a decrease in T. cucurbitaceus fecundity when females were treated as nymphs. This parameter was also affected by Bordelaise broth regardless of whether it was applied to nymphs and adults of the mirid. …”

Exploring the molecular differentiation of sex chromosomes in Anastrepha fraterculus sp. 1 using comparative genomic hybridization (CGH) por Giardini, Maria Cecilia, Milla, Fabian Horacio, Conte, Claudia Alejandra, Lanzavecchia, Silvia Beatriz, Nieves, Mariela

“…Our results showed that the X1 and X2 share complete homology in euchromatic regions, also sharing similar sequences with the Y5 chromosome in the centromeric region. Females X1X1 and X1X2 exhibited repetitive DNA in telomeric regions which contributed to their morphological differentiation, while the Y chromosome evidenced the accumulation of specific and differential repetitive sequences. …”

Morphological descriptions of the nymph and adults of Ornithodoros clarki, the larva and nymph of Ornithodoros rondoniensis, with notes on their phylogenetic relationships por Labruna, Marcelo B., Nava, Santiago, Rebollo Hernández, Andrea, Guzman Cornejo, Carmen M., Hernández, Ligia V., Domínguez, Lillian, Muñoz-Leal, Sebastian, Venzal, José Manuel

“…However, these two species are morphologically distinct based on specific patterns of coxal folds, idiosomal mammillae and pilosity, and female genital flap. In contrast, the larvae of O. clarki and O. rondoniensis are morphologically identical, except for a general larger size of the former species; this slight difference is corroborated by Principal Component Analysis (PCA) by using 40 morphometric variables. …”
