Contagious Caprine Pleuropneumonia in Goats: Causes, Symptoms, Treatment and Prevention

Introduction

Contagious Caprine Pleuropneumonia (often shortened to CCPP) is one of the most serious lung diseases of goats worldwide. It spreads quickly through a herd, causes severe pneumonia, and can kill many animals in a short time. CCPP is especially important in Africa, Asia, and the Middle East, where goats are a major source of meat, milk, fiber, and income for small farmers.

Because this disease is so contagious and deadly, it is listed by the World Organisation for Animal Health (WOAH/OIE) as a notifiable disease. That means suspected cases should be reported to veterinary authorities.

What is Contagious Caprine Pleuropneumonia in Goats?

Contagious Caprine Pleuropneumonia in goats is a highly contagious respiratory disease that mainly affects the lungs and the lining of the chest cavity (the pleura).

Key points:

Species affected: Primarily goats; it can also infect some wild ruminants. It rarely affects sheep and does not affect cattle.
Causative agent: The disease is caused by a special type of bacteria called Mycoplasma capricolum subspecies capripneumoniae (Mccp).
Type of disease: Acute (comes on quickly), highly contagious, and often fatal pneumonia with inflammation of the pleura (pleuropneumonia).
Economic impact: CCPP can cause very high illness and death rates (morbidity up to 100%, mortality up to 60–100% in outbreaks), leading to major economic losses in goat-producing regions.

In affected goats, the lungs become inflamed and covered with fibrin (a yellowish coating), and fluid collects in the chest cavity. Damaged lung tissue may harden and stick to the chest wall, making it difficult or impossible for the goat to breathe properly.

Causes of Contagious Caprine Pleuropneumonia in Goats

The main bacteria

The primary cause of contagious caprine pleuropneumonia in goats is the bacterium:

Mycoplasma capricolum subsp. capripneumoniae (Mccp)

Mycoplasmas are very small bacteria that do not have a cell wall. They are fragile outside the animal but can cause severe disease once they invade the lungs. Mccp is considered the sole agent specifically responsible for CCPP.

Older literature sometimes mentions other mycoplasmas (for example Mycoplasma mycoides subspecies) in relation to CCPP or similar syndromes, but current scientific evidence clearly points to Mccp as the specific causative agent of contagious caprine pleuropneumonia.

How the disease spreads

Contagious Caprine Pleuropneumonia in goats spreads mainly:

By close contact between goats through droplets when sick animals cough, sneeze, or breathe heavily
Through nasal secretions and respiratory droplets containing Mccp
During transport, at markets, or when new goats are introduced into a herd without quarantine

Because the organism is fragile in the environment and does not survive long outside the host, direct or very close contact between goats is usually needed for infection.

Risk factors on farms

Factors that increase the risk of contagious caprine pleuropneumonia in goats include:

High stocking density or crowding in pens and shelters
Poor ventilation and dusty or smoky environments
Stress from transport, sudden weather changes, or poor nutrition
Mixing animals from different sources without quarantine
Keeping goats in regions where CCPP is already present (endemic areas)

Clinical Signs and Symptoms of Contagious Caprine Pleuropneumonia in Goats

CCPP usually appears suddenly in a herd. In susceptible goats, the disease often progresses rapidly, sometimes causing death within a few days.

Common clinical signs of contagious caprine pleuropneumonia in goats include:

High fever: Elevated body temperature, often above 40°C (104°F)
Anorexia: Loss of appetite; goats stop eating or eat very little
Lethargy and weakness: Goats appear dull, depressed, reluctant to move
Severe respiratory signs:
- Difficult breathing (dyspnea) – goats breathe with effort, often with open mouth
- Fast breathing (polypnea) – very rapid respiratory rate
- Coughing – often painful, frequent cough
- Abdominal breathing – you may see the belly moving strongly with each breath
- Nasal discharge – may start clear and become mucopurulent (thick and yellow/green)
Pain in the chest: Goats may show pain when the chest is touched; they may grunt when breathing or moving
Reluctance to move: Goats often prefer to stand quietly with neck outstretched, elbows turned out, and forelegs spread to ease breathing
Rapid deterioration and death: In acute cases, goats can die within 3–7 days after the onset of signs, sometimes sooner.

In chronic or less severe cases, goats may show:

Long-lasting cough
Reduced weight gain or weight loss
Lower milk production
Recurrent mild fever and respiratory distress

However, the classic picture of contagious caprine pleuropneumonia in goats is sudden onset, severe pneumonia, and high death rates in a group of goats.

How to Diagnose Contagious Caprine Pleuropneumonia in Goats

On the farm (clinical suspicion)

A veterinarian will suspect contagious caprine pleuropneumonia in goats when they see:

Sudden outbreak of severe respiratory disease in a group of goats
High fever, coughing, nasal discharge, and marked breathing difficulty
High morbidity (many goats sick) and high mortality (many goats dying)
History of recent animal movement, purchase, or contact with outside goats

Listening with a stethoscope may reveal:

Harsh lung sounds
Areas of the lung with reduced or absent sounds (due to consolidation or fluid)

However, clinical signs alone are not enough to confirm contagious caprine pleuropneumonia in goats because other diseases can cause similar signs (for example, pasteurellosis, PPR with pneumonia, other mycoplasma pneumonias). Laboratory testing is needed for a definite diagnosis.

Laboratory diagnosis

Confirmed diagnosis of CCPP involves one or more of the following tests:

PCR (Polymerase Chain Reaction)
- Detects Mccp DNA in lung tissue, pleural fluid, or nasal/tracheal swabs
- Very useful for confirming contagious caprine pleuropneumonia in goats
- Faster and more sensitive than culture
Bacterial culture
- Isolation of Mccp from clinical samples (lung tissue, pleural fluid, nasal swabs)
- Definitive but technically difficult and slow; Mccp requires special media and conditions and can be hard to grow
Serology (antibody tests)
- Looks for antibodies against Mccp in goat blood
- Useful for herd-level diagnosis, surveillance, and mapping disease spread
- Does not always distinguish between current and past infection
Post-mortem examination (necropsy)
In dead goats, typical lesions of contagious caprine pleuropneumonia include:
- Unilateral (one-sided) or bilateral fibrinous pleuropneumonia
- Large amounts of yellowish fluid in the chest cavity (pleural effusion)
- Lung tissue that is firm, dark, and consolidated
- Fibrin layers on the lung surface and pleura
- Chronic cases may show adhesions where the lung sticks to the chest wall

These lesions, combined with PCR or culture confirmation of Mccp, provide a definite diagnosis.

Treatment of Contagious Caprine Pleuropneumonia in Goats

Because contagious caprine pleuropneumonia in goats is caused by a mycoplasma (which lacks a cell wall), many common antibiotics (such as penicillins and cephalosporins) are not effective. Mycoplasmas require drugs that target other bacterial processes.

Antibiotic options

Classes of antibiotics that can be effective against Mccp include:

Macrolides (for example, tylosin, tilmicosin, tulathromycin)
Tetracyclines (for example, oxytetracycline)
Fluoroquinolones (for example, enrofloxacin)

Studies and field experience show that appropriate anti-mycoplasma treatment can lead to recovery in many sick goats if started early.

Important points:

Treatment should be prescribed and supervised by a veterinarian; drug choice, dose, and withdrawal times (for milk and meat) must follow national rules.
In severe outbreaks, mass treatment of exposed goats may be considered, along with strict biosecurity.
Even with treatment, some goats may die due to the severity of lung damage.

Supportive care

In addition to antibiotics, supportive therapy can improve survival:

Provide easy access to clean water and good-quality feed
Minimize stress (handle animals quietly, avoid long moves)
Keep sick goats in a dry, well-ventilated, dust-free area, protected from extremes of cold and heat
Use anti-inflammatory drugs (NSAIDs) under veterinary direction to reduce fever and pain

Despite available treatments, CCPP often causes severe losses, especially where access to veterinary drugs and early diagnosis is limited. Therefore, prevention and control are more effective than relying on treatment alone.

Prevention and Control of Contagious Caprine Pleuropneumonia in Goats

Prevention of Contagious Caprine Pleuropneumonia in Goats

Because contagious caprine pleuropneumonia in goats is highly contagious and can spread quickly through regions, control requires a combination of farm-level biosecurity, vaccination (where available), and official movement control.

1. Biosecurity and good husbandry

Basic steps to reduce the risk of CCPP in your herd:

Quarantine new goats
- Keep newly purchased or returning goats separate for at least 2–4 weeks
- Observe them for any signs of respiratory disease before mixing with the main herd
Avoid mixing with unknown or high-risk animals
- Be cautious when sending goats to markets, shows, or communal grazing areas
- Limit contact with herds from areas where CCPP is known to occur
Improve housing and ventilation
- Provide well-ventilated shelters to reduce buildup of moisture and ammonia
- Avoid overcrowding; reduce stocking density in pens
- Keep bedding dry and clean
Reduce stress and support immunity
- Provide balanced nutrition, including adequate energy, protein, and minerals
- Provide shade and shelter from extreme weather
- Manage parasitism and other diseases to keep goats generally healthy

Good hygiene and husbandry practices help reduce disease incidence and severity.

2. Vaccination

In many endemic regions, vaccination is a key part of controlling contagious caprine pleuropneumonia in goats. Inactivated or attenuated vaccines based on local Mccp strains are used in some countries to protect goats and reduce outbreaks.

Key points:

Vaccination can significantly reduce clinical disease and deaths, but may not prevent infection in all animals.
Vaccination programs are often organized by government or regional veterinary services in high-risk areas.
Choice of vaccine, dose, and schedule should follow national guidelines and veterinary advice.

3. Movement control and reporting

Because CCPP is WOAH-notifiable, control at regional and national level may include:

Immediate reporting of suspected or confirmed cases to veterinary authorities
Movement restrictions on affected farms or regions to prevent spread
Testing and culling of infected animals in some control programs, especially in newly infected countries
Zoning and surveillance to track the presence and spread of CCPP

These measures are particularly important where the disease is new or where eradication is the goal.

Frequently Asked Questions About Contagious Caprine Pleuropneumonia in Goats

1. Is Contagious Caprine Pleuropneumonia in goats dangerous for humans?

No. There is no evidence that Mccp, the cause of contagious caprine pleuropneumonia in goats, infects humans. It is a serious disease for goats, but it is not considered a zoonosis. Current concerns focus on animal health and economic loss, not human infection.

2. How fast can CCPP spread in a goat herd?

CCPP can spread very quickly in a susceptible herd because it is highly contagious and transmitted by close contact and respiratory droplets. In naive (never-exposed) herds, almost all goats may become sick (near 100% morbidity), and many can die in a short period if not treated.

3. Can goats recover from contagious caprine pleuropneumonia?

Yes, some goats can recover, especially if:

The disease is recognized early
Effective anti-mycoplasma antibiotics (such as certain macrolides, tetracyclines, or quinolones) are used promptly
Supportive care (good housing, nutrition, reduced stress) is provided

However, even with treatment, death rates can remain high in severe outbreaks, and recovered goats may have reduced productivity.

4. Is there a vaccine for Contagious Caprine Pleuropneumonia?

Yes, vaccines for CCPP exist and are used in some countries with endemic disease. These are usually based on inactivated or attenuated Mccp strains. Vaccination can reduce clinical disease, deaths, and overall impact, especially when combined with good biosecurity and movement control. Availability and exact vaccine type depend on the country and region.

5. What is the difference between CCPP and ordinary pneumonia in goats?

While many bacteria and viruses can cause pneumonia in goats, contagious caprine pleuropneumonia has some special features:

Caused by Mycoplasma capricolum subsp. capripneumoniae (Mccp)
Often shows very high morbidity and mortality in a herd
Characterized by severe fibrinous pleuropneumonia, with large amounts of fluid and fibrin in the chest cavity and sometimes lung adhesions to the chest wall
Requires specific diagnostic tests (PCR, culture, serology) to confirm
Listed as a WOAH-notifiable disease, which is not the case for ordinary pneumonia

6. Should CCPP be reported to authorities?

Yes. Contagious caprine pleuropneumonia in goats is a notifiable disease under WOAH standards. Many countries require farmers and veterinarians to report suspected or confirmed cases to state or national veterinary authorities. Reporting helps control outbreaks and protect other farmers.

When to Call a Veterinarian

You should contact a veterinarian immediately if you notice in your goats:

Sudden onset of high fever, severe coughing, and respiratory distress in one or more animals
Many goats in the herd becoming sick with similar respiratory signs within a short time
Goats breathing with open mouths, extended necks, or obvious pain when breathing
Rapid deaths following respiratory signs
Unusual nasal discharge, especially thick, yellowish, or blood-tinged discharge, combined with fever

Also call a veterinarian if:

You have recently introduced new goats or returned goats from markets, shows, or other regions and they develop pneumonia
You live in or near an area where CCPP has been reported or is suspected

A vet can:

Examine the animals and assess whether contagious caprine pleuropneumonia in goats is likely
Collect samples for laboratory tests (PCR, culture, serology)
Start appropriate antibiotic and supportive treatment
Advise you on isolation, quarantine, vaccination, and biosecurity measures
Help with reporting to authorities, where required

Fast veterinary attention can save lives and limit spread within your herd and to neighboring farms.

Conclusion

Contagious Caprine Pleuropneumonia in goats is one of the most severe respiratory diseases affecting goats worldwide. It is caused by Mycoplasma capricolum subsp. capripneumoniae and spreads quickly between goats by close contact and respiratory droplets. Outbreaks often show very high illness and death rates and cause major economic losses, especially in Africa, Asia, and the Middle East.

Typical signs include high fever, loss of appetite, severe coughing, nasal discharge, and marked difficulty breathing. Many goats may die within a few days if the disease is not recognized and treated promptly. Diagnosis relies on clinical suspicion, post-mortem findings, and laboratory tests such as PCR and culture to confirm Mccp.

Treatment with appropriate anti-mycoplasma antibiotics and good supportive care can save some goats, but once contagious caprine pleuropneumonia in goats is established in a herd or region, it is difficult and costly to manage. Therefore, prevention and control are critical:

Strong farm biosecurity (quarantine, avoiding risky contacts, good housing and ventilation)
Vaccination in endemic areas, following veterinary and national guidelines
Rapid reporting of suspected cases and cooperation with veterinary authorities
Movement restrictions and surveillance when required

For farmers and students, the key message is simple: watch closely for sudden, severe pneumonia in goats, especially after introducing new animals or moving goats. If you suspect contagious caprine pleuropneumonia in goats, call a veterinarian without delay. Early action can protect your herd, your livelihood, and neighboring farms.
