Clinical Manifestations, Diagnosis, and Control Strategies of Campylobacteriosis in Veterinary Medicine

Many animals harbor Campylobacter spp. asymptomatically. However, under certain conditions, clinical disease can occur. Experimental infections in poultry may result in diarrhea, weight loss, and mortality1,2

In companion animals, infection typically presents as acute enterocolitis characterized by diarrhea, vomiting, anorexia, lethargy, dehydration, and abdominal pain. 

In livestock, young animals often exhibit more severe disease than adults. C. jejuni may cause bovine mastitis and calf enteritis, while C. fetus is strongly associated with abortion and infertility in cattle. 

Pathological Lesions 

Enterocolitis is the hallmark lesion in mammalian infections. Gross lesions range from catarrhal to hemorrhagic enteritis, with intestinal distension and fluid accumulation in severe cases1

Microscopic examination reveals villous atrophy, inflammatory infiltration, and mucosal edema. In sheep, abortions are associated with hepatic necrosis, peritonitis, and fetal organ damage. In cattle, lesions include placentitis, hepatitis, pneumonia, and fetal serositis1,3

Diagnostic Approach in Veterinary Settings1 

Diagnosis relies on bacterial culture, biochemical characterization, and molecular methods. Samples vary by species and include feces, cloacal swabs, and intestinal contents. 

Campylobacter requires microaerophilic conditions and grows optimally at 42°C. Due to its fastidious nature, ELISA and PCR are widely used for rapid detection. 

Treatment Considerations1 

Most infections are self-limiting and require supportive therapy such as fluid replacement. Antibiotics are reserved for severe or systemic infections. 

In dogs and cats, erythromycin and azithromycin are commonly used. In systemic cases, cefoxitin or enrofloxacin may be effective. 

Prevention and Control in Veterinary Practice1 

Prevention is primarily dependent on strict biosecurity measures. These include sanitation of animal housing, equipment disinfection, and prevention of cross-contamination between production cycles. 

Vector control targeting flies and rodents reduces transmission risk. Water treatment through chlorination is also essential in preventing infection spread. 

Additional strategies under investigation include bacteriophages, bacteriocins, vaccination, and competitive exclusion approaches. 

Final Clinical Perspective 

Campylobacteriosis remains a persistent challenge in veterinary medicine due to its asymptomatic carriage, environmental resilience, and strong zoonotic potential. Effective control depends on integrated management strategies rather than therapeutic intervention alone.
