Although rats are the recognized carrier of the fleas that transmits marine typhus, cats that encounter infected fleas can bring this disease home to you.
A parasitic bacterial disease that is transmitted to cats and that can also affect humans. M. haemofelis attaches to the infected cat’s red blood cells, which makes the cats immune system treat the red blood cells as a foreign substance, marking them for destruction. An infected flea can transmit the parasite to both your pet and you.
These parasites make their homes in the intestines of dogs, cats, and humans. While unusual in adults, children may get infected by accidentally swallowing an infected flea. Children and pets pass segments of tapeworms (proglottids), during bowel movements.
