RESULTS: There were 65 serologically confirmed cases during the study period. The …

Two cases with acute abdominal aneurysm and evidence of acute Q fever infection.

We report 2 patients with symptomatic aortic aneurysm and serologic evidence of acute Q fever with positive Coxiella burnetii PCR in blood/tissue. This suggests a role for acute Q fever in aneurysm progression. Diagnostic testing for Q fever infection in patients with symptomatic aneurysms in Q fever areas is recommended.

Self-reported sick leave and long-term health symptoms of Q-fever patients.

BACKGROUND: In The Netherlands, 1168 Q-fever patients were notified in 2007 and 2008. Patients and general practitioners (GPs) regularly reported persisting symptoms after acute Q-fever, especially fatigue and long periods of sick leave, to the public health authorities. International studies on smaller Q-fever outbreaks demonstrate that symptoms may persist years after acute illness. Data for the Dutch outbreaks were unavailable. The aim of this study is to quantify sick leave after acute Q-fever and long-term symptoms. METHODS: Our study targeted 898 acute Q-fever patients, notified in 2007

Заболеваемость лихорадкой Q (коксиэллозом) у овец из южного района Мармара, Турция.

В Турции имеется мало информации о лихорадке Q, вызванной зоонозом Coxiella signetii и передаваемой из домашних червей. Это исследование было направлено на изучение распространенности серопов в стадах овец из трех провинций (Бурсы, Баликешир и Канаккале). Серообследование проводилось на 42 стадах, которые были классифицированы по размерам. Сера была произвольно собрана у конкретных возрастных групп молодежи. Для выявления инфекции в овцах использовался комплект "CHEKIT Q-Fever ELISA". Результаты показали, что 20% (n=151) овец были серопозитивными. В общей сложности 34 стада (81 процент) обнару

Acute Q fever in Israel: clinical and laboratory study of 100 hospitalized patients.

BACKGROUND: Q fever is endemic in Israel, yet a large series describing the clinical spectrum of inpatients with acute Q fever in Israel is lacking. OBJECTIVES: To report on the clinical characteristics and outcome of hospitalized patients with acute Q fever in Israel. METHODS: We conducted a retrospective study of 100 patients hospitalized in six medical centers, in whom acute Q fever was diagnosed by the presence of immunoglobulin G and M antibodies to phase II Coxiella burnetti antigens. RESULTS: The mean age of the patients was 42.7 +/- 17.3 years with a male to female ratio of 1.6:1. A…

Chronic Q fever. Ninety-two cases from France, including 27 cases without endocarditis.

OBJECTIVE: Chronic Q fever is seldom recognized; before 1989, only 234 cases had been reported in the literature. The 92 cases of chronic Q fever collected at the French National Reference Center for Rickettsioses from 1982 through 1990 represent the largest series ever reported. PATIENTS: The patients included in the study were diagnosed between July 31, 1982, and August 1, 1990, at the French National Reference Center for Rickettsioses as having chronic Q fever by the following criteria: presence of antibody against Coxiella burnetii phase I antigen at a titer greater than or equal to 800 f…

[Acute cerebellar syndrome in preventive lithium treatment and atypical pneumonia in Q fever].

CNS-involvement in Coxiella burnetii infection is rare. Severe cerebellar symptoms with incomplete restitution were observed in 3 patients who developed Q-fever pneumonia associated with a long-term prophylaxis with lithium for manic-depressive disorder. Several pathophysiological mechanisms for these complications are discussed and a specific toxic-infectious interaction is suggested.

Seroepidemiology of Q fever among cats in New Brunswick and Prince Edward Island.

The indirect microimmunofluorescence test was used to determine the presence of antibodies to phase I and phase II Coxiella burnetii antigens in New Brunswick and Prince Edward Island cats. Twenty of 104 (19.2%) New Brunswick cats tested had antibodies to phase II antigen; five of these (4.8%) also had antibodies to phase I antigen. Six of 97 (6.2%) Prince Edward Island cats tested had antibodies to phase I and phase II antigens. Our data suggest that cats may be important in the epidemiology of Q fever in these provinces.

Vaccination of dairy cattle against Q fever (Coxiella burneti): results of field trials.

A phase I formalin-inactivated Q fever vaccine, using the Nine Mile strain of the organism, was tested for its ability to prevent dairy cows from shedding Coxiella burnetti in their milk. More than 1,400 Holstein-Friesian dairy calves and heifers from 5 dairies were used in field trials lasting over a 3-year period. Vaccination of 476 calves resulted in a geometric mean antibody titer of 1:123.3 compared with 1:2.4 for 486 nonvaccinated calves. The milk samples from 163 vaccinated calves were tested by mouse inoculation after the cows commenced lactation and were placed in their respective mil…

Q fever in Los Angeles County. Serological survey of human and bovine populations.

Q fever is endemic and enzootic in Los Angeles County. A serological survey conducted in 1949 is compared with a current survey. Infection in dairy herds is now almost universal, while the prevalence of positive complement fixation titers in man only increased from 1.2 percent to 2.3 percent (p <0.10). The relative stability in man is accounted for by the increase in temperature requirements for milk pasteurization, the decrease in consumption of raw milk and the decrease in the number of dairy farm foci.
