Synergic Effect of and Coinfection: Anatomopathological and Microbiome Evaluation.

and coinfection has been observed in the diagnostic routine; however, no studies have evaluated their interaction. This study aimed to characterize lesions and possible synergisms in experimentally infected pigs. Four groups of piglets, coinfection (CO), (BRA), (LAW), and negative control (NEG), were used.

Experimental Infection of Pigs with a ST 245 Isolated from an Asymptomatic Pig in a Herd with No History of Swine Dysentery.

Swine dysentery (SD) is characterized by a severe mucohemorrhagic colitis caused by infection with species. In infected herds the disease causes considerable financial loss due to mortality, slow growth rates, poor feed conversion, and costs of treatment. is the most common etiological agent of SD and infection is usually associated with disease.

Effect of porcine reproductive and respiratory syndrome virus 2 on angiogenesis and cell proliferation at the maternal-fetal interface.

Angiogenesis and cell proliferation in reproductive tissues are essential events for the maintenance of pregnancy, and alterations can lead to compromised fetal development and survival. Porcine reproductive and respiratory syndrome virus 2 (PRRSV-2) induces reproductive disease with negative financial and production impact on the swine industry. PRRSV-2 infection alters placental physiology through inflammatory and apoptotic pathways, yet fetal susceptibility varies.

Oral fluid for detection of exposure to Lawsonia intracellularis in naturally infected pigs.

To demonstrate the utility of oral fluid (OF) for indirect diagnostic detection of Lawsonia intracellularis (Li), 15 pig farms were studied. Serum and fecal samples were collected from 20 animals from five different age groups on each farm. OF samples were collected from animals in two pens of the same age groups.
