Food systems and the changing patterns of foodborne zoonoses.

This paper discusses food-borne zoonotic diseases by considering contemporary influences on food safety and examining pathogens at the human/animal interface. The authors also discuss the epidemiological surveillance of food-borne illnesses and the differences in disease statistics from one country to another. Before concluding with a number of recommendations, the paper highlights the importance of a collaborative approach to the prevention and control of food-borne diseases and discusses the need to co-ordinate the efforts of international agencies working in human health, animal health and food production. A regional case study is also included, in which the authors describe the food-borne disease situation in Latin America, as reported by surveillance systems in this region.

[Presence of Bartonella henselae in cats: natural reservoir quantification and human exposition risk of this zoonoses in Chile].

BACKGROUND: The availability of a serologic test for cat scratch disease in humans has allowed the diagnosis of an increasing number of cases of this disease in Chile. AIM: To perform a serological survey for Bartonella henselae among cats in Chile. MATERIAL AND METHODS: Blood samples from 187 cats living in three Chilean cities were obtained. IgG antibodies against Bartonella henselae were measured using indirect immunofluorescence. Blood cultures were done in 60 samples. The presence of Bartonella henselae in positive cultures was confirmed by restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR). RESULTS: The general prevalence of IgG antibodies against Bartonella henselae was 85.6%. No differences in this prevalence were found among cats younger or older than 1 year, or those infested or not infested with fleas. However domestic cats had a lower prevalence when compared with stray cats (73 and 90% respectively, p <0.01). Bartonella henselae was isolated in 41% of blood cultures. All the isolated were confirmed as Bartonella henselae by RFLP-PCR. CONCLUSIONS: This study found an important reservoir of Bartonella henselae in Chilean cats and therefore a high risk of exposure in humans who have contact with them.

Topically acquired bacterial zoonoses from fish: a review.

The main pathogens acquired topically from fish (through spine puncture or open wounds) are Aeromonas hydrophila, Edwardsiella tarda, Erysipelothrix rhusiopathiae, Mycobacterium marinum, Streptococcus iniae, Vibrio vulnificus and Vibrio damsela. S. iniae has recently emerged as a public health hazard associated with aquaculture, and M. marinum often infects home aquarium hobbyists. With the expansion of aquaculture and popularity of recreational fishing in Australia, medical practitioners can expect to see more infections of this nature. Diagnosis and treatment may be difficult, especially in view of emerging antibiotic resistance in fish pathogens.

[Emerging viral zoonoses: hantavirus infections].

Hantaviruses are rodent-borne agents belonging to the Bunyaviridae family. These viruses, which are found throughout Europe, Asia and the Americas, are maintained by different species of rodents, in which they produce chronic, inapparent infections. Humans become infected through contact with urine, saliva or faeces from infected rodents, mainly via the aerosol route. In humans, clinical disease occurs in the form of two major syndromes: haemorrhagic fever with renal syndrome (HFRS) or hantavirus pulmonary syndrome (HPS). Haemorrhagic fever with renal syndrome mainly occurs in Europe and Asia and HPS has only ever been reported in the Americas. Person-to-person transmission of hantaviruses, although uncommon, was described during an outbreak of HPS in southern Argentina. Most epidemics of HFRS and HPS occur in areas with large populations of rodents that have a relatively high prevalence of infection.

Virus zoonoses and their potential for contamination of cell cultures.

Silent virus infections of laboratory animals present a human health hazard, from direct exposure and from contamination of biological products for human use. Here we report two recent examples. In 1989, an outbreak of lymphocytic choriomeningitis virus (LCMV) infections was recognized among workers at a cancer research center after an animal caretaker developed viral meningitis. Investigation revealed that multiple tumor cell lines at the facility were infected with LCMV, as were research animals injected with these cell lines. Of 82 workers tested, eight (10%) were found to have been infected. The infected workers were more likely than other animal handlers to report handling athymic (nude) mice (p less than .0.007). The number of nude mice used in this facilty had increased five-fold in the previous year, possibly explaining the timing of the outbreak. This is the first reported LCMV outbreak since 1975, and the first to implicate nude mice as a source of human LCMV infections. In November 1989 and January 1990, infections caused by two distinct Ebola-like filoviruses were discovered in non-human primates at quarantine facilities in Virginia and Pennsylvania. Although 22 persons were considered to have high- or medium-risk exposures for Ebola infection, no Ebola-compatible illnesses occurred. One of the medium-risk persons had Ebola IgG antibodies confirmed by IFA and Western blot. Rigorous use of barrier precautions may have limited exposure and infection with these filoviruses. In February 1990, new groups of filovirus-infected monkeys were identified in Virginia and in Texas. Seroconversion occurred in four animal handlers, including one to very high titer, but again no illness was observed.(ABSTRACT TRUNCATED AT 250 WORDS)

[Occurrence of zoonoses in a natural reservoir in the West Bohemian Region. I. Tick-borne encephalitis--basic epidemiologic characteristics].

In 1960-1987 in the population of the West Bohemian region by means of various serological methods 621 cases of tick-borne encephalitis were diagnose. The disease was not present in the northern districts (Cheb, Sokolov, Karlovy Vary) and in the mountainous zone along the western frontier of the country. In other areas it is ubiquitary with the highest mean morbidity for the entire period - 5.1 cases per 100,000/year in the district Plzen-South. The morbidity of the population of the regional town was only slightly lower. The patients were most frequently from the age group of 20-29 years. In younger age groups there were twice as many men than women, in children and older age groups the differences were not significant. The incidence was highest in July and August. Only 5.5% cases had the character of an occupational infection. Tick-borne encephalitis is a leisure time disease in the West Bohemian region.
