Pasteurella multocida is usually transmitted by animal contact; however, in a significant proportion of cases, no animal exposure can be identified. Although vertical transmission has been identified in neonates, horizontal human-to-human spread has not been documented. A case of neonatal sepsis and meningitis resulting from horizontal transmission of P. multocida is described.

Hyaluronan (HA; [-3-GlcNAc-1-beta-4-GlcA-1-beta] ), an essential matrix polysaccharide of vertebrates and the molecular camouflage coating in certain pathogens, is polymerized by "HA synthase" (HAS) enzymes. Three HAS classes have been identified with biotechnological utility, but only the Class II PmHAS from Type A has been useful for preparation of very defined HA polymers in vitro. Two general chemoenzymatic strategies with different size products are possible: (1) repetitive step-wise extension reactions by sequential addition of a single monosaccharide from a donor UDP-sugar onto an acceptor (or "primer") comprised of a short glycosaminoglycan chain (e.

Respiratory diseases, such as pleurisy and pneumonia, cause significant health and economic losses in pig production. This study evaluated 867 finishing pigs from a farm with a history of respiratory issues, using macroscopic lesion scoring (SPES and CVPC), histopathological analysis, qPCR diagnostics, and economic modeling. Severe pleurisy (scores 3 and 4) was observed in 42.

The bovine respiratory disease complex (BRD) is a multifactorial disease caused by various bacterial and viral pathogens. Using rapid pathogen detection techniques is helpful for tailoring therapeutic and preventive strategies in affected animals and herds. The objective of this study was to report the frequency of 10 pathogens by multiplex RT-qPCR on samples submitted for BRD diagnosis to a diagnostic laboratory (Biovet Inc.

Clinical signs of respiratory disease are common in Lao goats. To identify the causative agents involved in this clinical syndrome, a matched case-control study was conducted across 70 smallholder goat holdings in Savannakhet province. Fifty paired nasal swab samples were collected from goats with respiratory signs (cases) and unaffected (control) goats from 27 goat holdings.

Ethiopia, with an estimated chicken population of 17 million, serves as a source of high-quality animal protein, helping to reduce malnutrition, improve nutritional status, and provide food and food products. However, Ethiopia has not fully leveraged the value of chicken production due to various bacterial diseases, with fowl cholera (FC) being the most common. Therefore, the objective of this review is to highlight the current trends in the diagnosis of FC in chickens and asses its phenotypic drug resistance patterns in Gondar City.
