[Risk factors associated with the presence of brucellosis in mixed establishments (caprine and bovine) in the province of Formosa, Argentina].

Brucellosis is a zoonotic disease with a worldwide distribution that causes significant productive losses and negative impacts on public health. The aim of this work was to identify the risk factors associated with the presence of brucellosis in mixed farms (cattle/goats) in the central-western region of the province of Formosa. Sixty seven mixed farms with 7,855 animals (2,943 cattle and 4,912 goats) were randomly sampled during 2022/2023.

[Prevalence and geographical distribution of bovine sexually transmitted diseases in the province of Formosa, Argentina].

Bovine genital campylobacteriosis (BGC) and bovine trichomonosis (BT) are sexually transmitted diseases (STDs) that affect bovine breeding herds, decreasing their reproductive efficiency. The objective of this work was to estimate the prevalence of these diseases and their temporal-spatial distribution in the province of Formosa, Argentina. The cross-sectional study conducted between 2018 and 2021 included a total of 15,571 bulls, inter-herd prevalence being 29.

Mouse retinal cell behaviour in space and time using light sheet fluorescence microscopy.

As the general population ages, more people are affected by eye diseases, such as retinopathies. It is therefore critical to improve imaging of eye disease mouse models. Here, we demonstrate that 1) rapid, quantitative 3D and 4D (time lapse) imaging of cellular and subcellular processes in the mouse eye is feasible, with and without tissue clearing, using light-sheet fluorescent microscopy (LSFM); 2) flat-mounting retinas for confocal microscopy significantly distorts tissue morphology, confirmed by quantitative correlative LSFM-Confocal imaging of vessels; 3) LSFM readily reveals new features of even well-studied eye disease mouse models, such as the oxygen-induced retinopathy (OIR) model, including a previously unappreciated 'knotted' morphology to pathological vascular tufts, abnormal cell motility and altered filopodia dynamics when live-imaged.

[Epidemiology of caprine and ovine brucellosis in Formosa province, Argentina].

An epidemiological study of brucellosis was carried out in 516 goats and mixed flocks (goat/sheep) from the three agro-ecological regions of Formosa province, Argentina. Serum samples from a total of 25401 goats and 2453 sheeps were analyzed using buffered plate agglutination test (BPAT) and complement fixation test (CFT). Bacteriological and PCR analyses on milk samples from goats in three flocks with a history of brucellosis and recent abortions were also performed.
