Q fever is serologically cross-reactive with other intracellular microorganisms. However, studies of the serological status of Mycoplasma pneumoniae and Chlamydophila pneumoniae during Q fever are rare. We conducted a retrospective serological study of M. pneumoniae and C. pneumoniae by enzyme-linked immunosorbent assay (ELISA), a method widely used in clinical practice, in 102 cases of acute Q fever, 39 cases of scrub typhus, and 14 cases of murine typhus. The seropositive (57.8%, 7.7%, and 0%, p<0.001) and seroconversion rates (50.6%, 8.8%, and 0%, p<0.001) of M. pneumoniae IgM, but not M. pneumoniae IgG and C. pneumoniae IgG/IgM, in acute Q fever were significantly higher than in scrub typhus and murine typhus. Another ELISA kit also revealed a high seropositivity (49.5%) and seroconversion rate (33.3%) of M. pneumoniae IgM in acute Q fever. The temporal and age distributions of patients with positive M. pneumoniae IgM were not typical of M. pneumoniae pneumonia. Comparing acute Q fever patients who were positive for M. pneumoniae IgM (59 cases) with those who were negative (43 cases), the demographic characteristics and underlying diseases were not different. In addition, the clinical manifestations associated with atypical pneumonia, including headache (71.2% vs. 81.4%, p=0.255), sore throat (8.5% vs. 16.3%, p=0.351), cough (35.6% vs. 23.3%, p=0.199), and chest x-ray suggesting pneumonia (19.3% vs. 9.5%, p=0.258), were unchanged between the two groups. Clinicians should be aware of the high seroprevalence of M. pneumoniae IgM in acute Q fever, particularly with ELISA kits, which can lead to misdiagnosis, overestimations of the prevalence of M. pneumoniae pneumonia, and underestimations of the true prevalence of Q fever pneumonia.

Secular trends in milk-borne diseases in the U.S.A. show numerous outbreaks associated with ingestion of raw milk in the early 1900s until the end of World War II. Diseases common in this period, but no longer milk-borne, were typhoid fever, scarlet fever, septic sore throat, diphtheria, tuberculosis, shigellosis, and milk sickness. Milk-borne and milk-product-borne diseases rarely reported somewhere in the world were botulism, Escherichia coli enteritis, Pseudomonas aeruginosa enteritis, listeriosis, Clostridium perfringens enteritis, Bacillus cereus gastroenteritis, Haverhill fever, Q fever, hepatitis A, poliomyelitis, toxoplasmosis, histamine intoxication and hypertension. After most milk was pasteurized, outbreaks decreased dramatically. Milk-borne diseases of contemporary importance in the U.S.A. are salmonellosis, campylobacteriosis, staphylococcal intoxication, brucellosis, and yersiniosis. These have usually been associated with ingestion of raw milk, certified raw milk, home-made ice cream containing fresh eggs, dried milk, pasteurized milk which was contaminated after heat processing, or either cheese made from raw milk or cheese in which starter activity was inhibited during its manufacture.
