Opis:
Introduction. Coxiella burnetii is an obligatory intracellular bacterial pathogen causing the zoonotic disease Q fever. The most common reservoirs of C. burnetii are wild mammals, birds and ticks. Pregnant domestic ruminants infected with this bacterium are also a major source of human infection. Materials and method. The serological prevalence of C. burnetii in goats and sheep diagnosed with adverse pregnancy outcomes was assessed by undertaking a survey on 800 dairy goats and 800 dairy ewes reared in four different regions of Greece (Macedonia, Thrace, Thessaly, and Peloponnese). A stratified sampling was carried out, taking also as a criterion the age of the animals. Serum antibodies were analyzed by a commercial ELISA according to the manufacturer’s recommendations. Results. Generally, there was a statistically significantly higher serological prevalence of C. burnetii (14.4%) in goats compared to sheep (8%). Serological prevalence was higher in adults (15.5% in goats and 8.5% in sheep) compared to yearlings (7.4% in goats and 4.6% in sheep). The prevalence increased significantly with age only in goats. Finally, all animals reared in Peloponnese had a prevalence significantly higher (21% in goats and 18% in sheep) than animals reared in the other three regions. Conclusion. To the best of the authors’ knowledge, this is the first report that associates C. burnetii with reproductive disturbances of domestic ruminants in Greece. However, considering the importance of coxiellosis for public health, further investigations are required on its epidemiology regarding abortion, premature delivery, stillbirth and weak offspring in small ruminants, as well as in other domestic and wild animal species.

Opis:
Gorączka Q (febris Q, coxiellosis) jest występującą globalnie chorobą ludzi i wielu gatunków zwierząt. Wywołuje ją, namnażająca się wewnątrzkomórkowo, bakteria Coxiella burnetii (rząd Legionellales), wytwarzająca spory – wyjątkowo wytrzymałe na działanie czynników fi zyko-chemicznych. W Polsce, jako choroba ludzi, znana jest od 1956 roku, zaś najczęstszym źródłem zakażenia dla ludzi są: zakażone bydło i owce oraz skażone środowisko bytowania tych zwierząt. Wycinkowo jedynie rozpoznana epidemiologicznie i sporadycznie diagnozowana u ludzi, występuje niewątpliwie na terenie całego kraju. Ofi cjalnie zgłaszane przypadki u ludzi, odzwierciedlają (według szacunku jednego z nas, jedynie około 1% przypadków klinicznych u ludzi w Polsce). Motywem przedstawionych poniżej badań, były 3 ogniska epizootyczno-epidemiczne, które pojawiły się latem i wczesną jesienią 2008 roku, na pograniczu województw lubelskiego i podkarpackiego, zrazu u krów mlecznych i wtórnie, u ludzi z grup narażenia zawodowego. W pracy przedstawiono wstępne wyniki badań w kierunku gorączki Q u osób zawodowo narażonych. Przebadano serologicznie grupę 135 osób. W celu wykazania obecności przeciwciał IgG zastosowano metodę immunofl uorescencji pośredniej (IFA) w fazie I i II oraz metodę odczynu wiązania dopełniacza (OWD) w fazie II. Przedstawione wyniki traktujemy jako wstępne, zaś badania kontynuujemy wespół z Laboratorium Diagnostyki Serologicznej Państwowego Instytutu Weterynaryjnego – Państwowego Instytutu Badawczego w Puławach, której kierownikiem jest dr wet. Krzysztof Niemczuk, uczestnik wspólnego Grantu, oraz z oddziałami obserwacyjno-zakaźnymi w Biłgoraju i Dębicy i Narodowym Instytutem Zdrowia Publicznego-Państwowym Zakładem Higieny

Objectives The aim of this survey was to assess the seroprevalence of antibodies against Coxiella burnetii (C. burnetii) in subjects at risk of exposure in Sicily, Southern Italy. Material and Methods Prevalence of IgG antibodies to C. burnetii phase II antigens was evaluated by ELISA in a group of 140 workers at risk of exposure (38 veterinarians, 38 slaughterhouse workers, 44 livestock handlers, 20 laboratory and technical personnel) included in a medical surveillance program and in 42 control subjects. Positive samples were classified as suggestive of prior exposure to C. burnetii. Results Antibodies against C. burnetii were detected in 88 out of 140 (62.9%) exposed workers and in 6 out of 42 (14.3%) subjects of the control group. The variables evaluated did not seem to have a significant effect on seropositivity to Coxiella with the exception of symptoms in the last 6 months preceding the survey. Conclusions Our study demonstrated a high seroprevalence of C. burnetii in the group of exposed workers in comparison to non-exposed subjects of the control group. Clinical illness appears to be rare; nevertheless, physicians should consider Q fever in patients with compatible symptoms and occupational exposure to animals and their products. As aerosols represent the main route of infection in animals and humans, these workers are strongly advised to wear respiratory masks. In addition, occupational physicians should consider routine serologic evaluation and vaccination of occupationally exposed workers.

Introduction and Objective. The problem of occupational biohazards is very important, especially in the field of agriculture and in human and veterinary medicine. The aim of the study was to determine the potential sources of infection in veterinary professionals with selected zoonotic agents, including: Toxoplasma gondii, Giardia duodenalis, Leptospira spp., Cryptosporidium spp. and Coxiella burnetii. Materials and Method. A total of 50 air samples from barns, piggeries and veterinary surgeries were examined for the presence of Leptospira spp. and C. burnetii DNA. Serum samples of 86 pigs and 80 cows were tested for the presence of antibodies to Leptospira spp. and to phase I and II C. burnetii antigens. Serum of 70 cats were tested for the presence of antibodies to T. gondii and 65 samples of cat faeces for the presence of T. gondii oocysts. The presence of G. duodenalis and Cryptosporidium spp. were examined in 50 of dog faeces and 50 of bovine faeces samples. Results. DNA of Leptospira spp. was detected in 2 air samples from the piggeries (4%). C. burnetii DNA was not found in any sample. Anti-Leptospira spp. antibodies were detected in 51 (59.3%) of examined pigs. Neither anti-Leptospira spp. nor anti-C. burnetii antibodies were found among samples of bovine serum. Anti-T. gondii antibodies was found in 52 cat serum samples (74.3%). Among samples of cat faeces, no T. gondii oocysts were detected. In one sample of cattle stool (2%), G. duodenalis was detected and in another (2%) – Cryptosporidium spp. G. duodenalis was detected in 7 samples (14%) and Cryptosporidium spp. in 2 samples (2%) of dog faeces. Conclusions. The results of this study demonstrate the potential risk of infection with Leptospira spp. in veterinarians working with pigs. Veterinarians could be also be at risk of infection with T. gondii and G. duodenalis.

Opis:
Introduction and objective. Previous studies on tick-borne pathogens in the avian population have focused mainly on the detection of the agents in ticks collected from birds, but data about the presence of tick-borne bacteria in these animals are scant. The aim of the presented study was to verify the exposure to some zoonotic tick-borne bacteria, in particular, Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, Coxiella burnetii, and the Rickettsia species of the Spotted Fever Group (SFG), in pheasants (Phasianus colchicus) living in a central Italy area, characterized by conditions favourable for the diffusion of the ticks. Materials and method. Blood serum samples from 276 farm-reared pheasants were examined by indirect immunofluorescence antibody test to detect antibodies against the 4 reported pathogens. Results. A total of 124 (44.92%) birds resulted as seropositive: in particular 3 (1.08%) to C. burnetii, 31 (11.23%) to A. phagocytophilum, 46 (16.67%) to B. burgdorferi s.l., 49 (17.75%) to SFG Rickettsia spp. antigens. Three pheasants resulted positive both to A. phagocytophilum and B. burgdorferi s.l. antigens, whereas 2 – both to B. burgdorferi s.l. and SFG Rickettsia spp. antigens. The antibody titers varied from 1:40–1:320. Conclusions. The obtained results show that the pheasants had developed antibodies to the investigated tick-borne agents. For this reason, they seem to be involved in the epidemiology of the studied tick-borne bacteria.

Opis:
An epidemiological study was carried out to determine the herd prevalence of Chlamydophila abortus and Coxiella burnetii antibodies in goats covered by a milk recording program in Poland. The survey took place in 2007 and 48 herds located in different parts of the country were involved. A representative sample from each herd was taken by a simple random sampling allowing to detect seropositivity of a herd on a 95% level of confidence. In total 918 goats were tested for specific antibodies against both germs with the use of enzyme-linked immunosorbent assays. In addition, history of reproductive failures was recorded in these herds. The survey revealed that the herd prevalence of C. abortus was 4.2% (2 herds) while no C. burnetii antibodies were found. Abortions were reported to be a problem in 80% of herds while repeating estrus was encountered in 46% of herds. Reproductive failure concerned two seropositive herds as well. Since the germ is present in the population, it has to be taken into consideration in diagnostic process. Nevertheless, the results of the present study indicate that C. abortus infection occurs infrequently in Polish goats. As no antibodies against C. burnetii were detected in the screened sample the risk of goat-to-human transmission of both bacteria in Poland seems to be very low.

Opis:
An early, rapid and definite detection for the presence of biowarfare agents, pathogens, viruses and toxins is required due to their harmful effect to human population. Those potentially encountering the aforementioned include people involved in civil rescue and security, homeland security, military operations, as well as public transportation securities such as airports, metro and railway stations. This work informs the reader of an electrochemical genosensor with an integrated microsystem array combined with microtube fluidics that allows simultaneous detection of different biowarfare agents such as Bacillus anthracis, Brucella melitensis, Bacteriophage lambda, Francisella tularensis, Burkholderia mallei, Coxiella burnetii, Yersinia pestis, and Bacillus thuringiensis var. kurstaki. The chip electrode arrays were modified via coimmobilisation of a 1:100 (mol/mol) mixture of a thiolated probe and a polyethyleneglycol terminated bipodal thiol. Herein, PCR products from relevant biowarfare agents were detected reproducibly through a sandwich assay format with the target hybridised between a surface immobilised probe into the electrode and a horseradish peroxidase-labelled secondary reporter probe, which provided an enzyme based electrochemical signal. Cross-reactivity studies over potential interfering DNA sequences have demonstrated high selectivity using the developed platform producing high-throughput.

Opis:
Q fever is an infectious disease of humans and animals caused by Gram-negative coccobacillus Coxiella burnetii, belonging to the Legionellales order, Coxiellaceae family. The presented study compares selected features of the bacteria genome, including chromosome and plasmids QpH1, QpRS, QpDG and QpDV. The pathomechanism of infection – starting from internalization of the bacteria to its release from infected cell are thoroughly described. The drugs of choice for the treatment of acute Q fever are tetracyclines, macrolides and quinolones. Some other antimicrobials are also active against C. burnetii, namely, telitromycines and tigecyclines (glicylcycline). Q-VAX vaccine induces strong and long-term immunity in humans. Coxevac vaccine for goat and sheep can reduce the number of infections and abortions, as well as decrease the environmental transmission of the pathogen. Using the microarrays technique, about 50 proteins has been identified which could be used in the future for the production of vaccine against Q fever. The routine method of C. burnetii culture is proliferation within cell lines; however, an artificial culture medium has recently been developed. The growth of bacteria in a reduced oxygen (2.5%) atmosphere was obtained after just 6 days. In serology, using the IF method as positive titers, the IgM antibody level >1:64 and IgG antibody level >1:256 (against II phase antigens) has been considered. In molecular diagnostics of C. burnetii infection, the most frequently used method is PCR and its modifications; namely, nested PCR and real time PCR which detect target sequences, such as htpAB and IS1111, chromosome genes (com1), genes specific for different types of plasmids and transposase genes. Although Q fever was diagnosed in Poland in 1956, the data about the occurrence of the disease are incomplete. Comprehensive studies on the current status of Q fever in Poland, with special focus on pathogen reservoirs and vectors, the sources of infection and molecular characteristics of bacteria should be conducted.
