Summary
Acute septicaemia caused increased mortality in young goslings. Streptococcus gallolyticus subsp. pasteurianus, a Gram-positive bacterium, was identified as the causative agent in affected birds.
Area of Science:
- Veterinary Pathology
- Microbiology
- Avian Health
Background:
- Goslings are susceptible to bacterial infections.
- Septicaemia can cause significant mortality in young poultry.
- Identifying causative agents is crucial for disease management.
Purpose of the Study:
- To investigate the cause of increased mortality in 2-3-week old goslings.
- To identify the specific bacterial pathogen responsible for the observed septicaemia.
Main Methods:
- Post mortem examination of deceased goslings.
- Gross and histopathological examination of visceral organs.
- Bacteriological isolation and identification, including Gram staining and pure culture.
Main Results:
- Gross lesions included visceral congestion and haemorrhages.
- Histopathology revealed generalised congestion, bacterial colonies, septic splenitis, and hepatitis.
- Gram-positive bacteria were identified, with Streptococcus gallolyticus subsp. pasteurianus isolated from multiple cases.
Conclusions:
- The findings are consistent with acute septicaemia in goslings.
- Streptococcus gallolyticus subsp. pasteurianus is identified as a likely cause of mortality.
- This highlights the importance of bacterial disease surveillance in young poultry.

01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
