True or false: Serology is the most effective method to detect pathogens in immunodeficient animals.

Serology is a method that detects antibodies or antigens in the serum, which can provide insights into an animal's immune response to infections. However, in immunodeficient animals, the immune system may not mount a typical antibody response. As a result, serological tests can yield false negatives because there might not be sufficient antibodies present for detection even if a pathogen is present.

In such cases, other methods, such as polymerase chain reaction (PCR) or culture-based techniques, may be more effective as they can directly detect the pathogen's genetic material or isolate the organism itself, regardless of the host's immune status. Thus, the effectiveness of serology for detecting pathogens in immunodeficient animals is limited, making the statement false.
