Rhodococcus equi pneumonia in foals
Modern Veterinary Practice
|October 1, 1984
Summary
Rhodococcus equi pneumonia in foals can be challenging to treat due to abscess formation. This case study shows successful recovery using specific antibiotics and supportive care in a Quarter Horse colt.
Area of Science:
- Veterinary Medicine
- Equine Health
- Microbiology
Background:
- Rhodococcus (Corynebacterium) equi pneumonia is a significant respiratory disease in foals.
- Treatment failure can occur due to the bacterium's propensity to form pulmonary abscesses.
- Diagnosis typically involves auscultation, radiography, hematology, and transtracheal aspiration.
Observation:
- A 2-month-old Quarter Horse colt presented with depression, anorexia, fever, and abnormal lung sounds.
- The colt was unresponsive to initial penicillin therapy.
- Radiographic findings confirmed pneumonia.
Findings:
- Transtracheal washes identified the causative organism.
- Culture and sensitivity testing guided antibiotic selection.
- Treatment involved chloramphenicol, erythromycin, and trimethoprim-sulfadiazine, along with supportive care.
Implications:
- Successful treatment of Rhodococcus equi pneumonia is achievable with appropriate antibiotic selection and supportive measures.
- This case highlights an effective therapeutic strategy for refractory cases.
- Early diagnosis and targeted treatment are crucial for favorable outcomes in foal pneumonia.

01:28Pneumonia IV: Management
The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
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...
01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
