Abstract
This report describes clinical, macro and microscopic changes observed in an outbreak of septicemic salmonellosis in pre-weaned calves caused by Salmonella. The necropsy of calves was performed and gross lesions were identified and characterized. The differential diagnosis included hemoparasites (Anaplasma, Babesia bigemina, Babesia bovis and Ehrlichia spp.), Leptospira and Escherichia coli. The course of infection was three days from the moment calves got sick until death. Some of the clinical signs included apathy, reduced solid food ingestion, hyperthermia and mucosal congestion. Postmortem findings were mostly congestion of oral, ocular and rectal mucosa; petechiae were observed in the vaginal, bladder and sublingual mucosa, serosa of the rumen, reticulum, omasum and small intestine; the lungs were congested. Microscopic examination of the lung was characterized by inflammatory infiltration mostly of neutrophils, fibrin and moderate multifocal haemorrhagic alveolar and bronchial lumen. Vasculitis, necrosis and thrombosis in the liver, gallbladder, spleen, and hypophysis were also observed. Salmonellosis is an important disease of dairy cattle resulting in increased morbidity and mortality of affected animals. This report offers a better understanding of the clinical and pathological characteristics of the disease and demonstrates the importance of diagnostic approaches in cases of Salmonella dublin infections.
