INTRODUCTION AND OBJECTIVES
The Merina Branca (MB) and Merina Preta (MP) breeds are autochthonous breeds from Alentejo, characterized by their high rusticity, adaptation to soil and climate conditions and natural resistance to diseases. Bronchopulmonary parasites (BP) are caused by several species of nematodes, in particular Dictyocaulus filaria, which can compromise immunity, predispose to secondary infections, negatively affect meat and milk production, and in the case of massive infections, lead to the death of the animal. animal. This study aimed to determine the prevalence of BP parasites, quantify the production of larvae, and analyze the differences in susceptibility to these parasites between the two races.

INTRODUCTION AND OBJECTIVES
Tick-borne diseases cause significant economic losses in ruminants worldwide. Anaplasma phagocytophilum is a rickettsia associated with tick fever in sheep, manifesting as high fever and neutropenia. Although rarely fatal, it can be a predisposing factor for other diseases. Infection with this agent is associated with abortions and decreased spermatogenesis in sheep and adult cattle, as well as production losses in lambs. A. phagocytophilum can infect several species, including humans, causing human granulocytic anaplasmosis. The objective of this work was to determine the prevalence of A. phagocytophilum in sheep from the Alentejo region.
