[Clinicobacteriological study of Pasteurella multocida infection as a zoonosis. (2)--Comparisons of P. multocida separated from patients and their pet dogs and cats].

A total of 17 strains of Pasteurella multocida, of which 13 were isolated from patients treated at Nihon University Itabashi Hospital or Nihon University Surugadai Hospital between April, 1984 and March, 1991 and 4 from 1 dog and 3 cats kept by the patients, were evaluated with respect to their biochemical properties, sensitivity to drugs, and serotype. The isolated strains were all considered to be Pasteurella multocida subsp. multocida because of the agreement of their responses to indole, sorbitol and dulcitol with those of this subspecies, except for 1 sorbitol-negative strain of Pasteurella multocida subsp. septica isolated from 1 patient who had been bitten by a cat. All the isolated strains showed high sensitivities to various drugs. The serotype was capsular type A, which is often observed in cats and dogs, in 7 strains, which consisted of 6 of the 7 strains derived from the airway of the patients and 1 of the 6 strains derived from bit or scratch wound. The remaining strains could not be classified. Five morphological types, namely 1, 3, 3.8, 6, and 8 were observed. In 2 patients, Pasteurella multocida subsp. multocida of the same serotype was also isolated from their cats. One of these patients had intimate contact with the cat including kissing. Our findings suggest that: 1) Pasteurella multocida subsp. multocida has been responsible for most conventional cases of Pasteurella multocida infection. 2) Strains isolated from patients differ in the capsular type according to the disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Human Monieziasis expansa: the first Egyptian parastic zoonosis.

This paper reports the first Egyptian zoonotic infection with the common tapeworm of sheep, Moniezia expansa. Perhaps this is the first human monieziasis expansa in the sheep raising countries worldwide. Diagnosis was based on recovery of the characteristic eggs from the stool of a fifteen-years-old shepherd. A single dose of Niclosamide one gram proved effective.

[Tick borne zoonosis: selected clinical and diagnostic aspects].

Tick-borne zoonotic infections are among the most diffuse vector borne diseases: these large group of infections is caused by different microorganisms: Babesia spp., Borrelia spp., Rickettsia spp., Ehrlichia spp., Francisella tularensis, Coxiella burnetii) and tick-borne encephalitis virus. Babesiosis is caused by the protozoa (sporozoa) Babesia microti and it is quite rare in humans in Europe. The ixodids ticks are the competent vectors. A few symptomatic cases have been reported, mainly in splenectomized patients. The laboratory diagnosis is made by the microscopic identification of the parasites within the red blood cells in blood smears. The serologic diagnosis, based mainly upon IFA and WB techniques has only an epidemiological interest. Lyme borreliosis (Lyme disease) has been recognized as the most frequent vector borne disease in mild climate areas. The etiologic agent is a spirochete, belonging to the Borrelia burgdorferi sensu lato complex: B. burgdorferi sensu stricto, B. garinii and B. afzelii. Several additional species of this geno-complex have been identified but their pathogenic capability for humans still needs to be elucidated. Lyme borreliosis is clinically divided into three different clinical stages: the early disease, the disseminated infection and the persistent infection. Individual stages are caused by the diffusion of the spirochetes to different anatomic districts of the body. The main clinical symptoms are, for each stage: the erythema chronicum migrans in the early infection, the peripheral nerves and joint involvement in disseminated diseases and the acrodermatitis chronica atrophica (ACA) with central nervous system involvement in the late disseminated infection. The microbiological diagnosis is achieved by serologic techniques (IFA, EIA, WB) and by isolation of the spirochetes (in vitro culture and DNA amplification methods). Tick-borne relapsing fever (TBRF) is occasionally transmitted to humans by the soft ticks Ornithodorus and is caused by Borrelia spp. Different borreliae are responsible for TBRF in various geographic areas. The laboratory diagnosis is based upon the identification of spirochetes in peripheral blood by microscopic observation of Giemsa stained smears. Rickettsiosis diseases are caused worldwide by the obligate intracellular bacteria belonging to the genus Rickettsia. In the Mediterranean area the most frequently identified rickettsia is R. conorii, that causes the so called Mediterranean spotted fever. The serologic detection of a specific antibody response by IFA techniques is the most prominent tool for the diagnosis. In addition, the PCR method can be applied. Bacteria of the genus Ehrlichia are well known pathogens in veterinary medicine. Since the last decade their zoonotic capability has emerged and E. chafeensis, E. canis and the so called human granulocytic agent (HGE) have been identified in human diseases following a tick bite. The ehrlichiosis is characterized, in human, by a mild fever associated with lymphoadenopathy. The diagnosis is made on the identification of morulae (the intracytoplasmatic inclusion of the growing rickettsiae) in the white cells of peripheral blood. In addition the molecular diagnosis is also possible by PCR. Tick-borne encephalitis (TBE) is the only viral arthropod-borne encephalitis in Europe: it is caused by a flavivirus and it can also be transmitted by the ingestion of goat raw milk. The more relevant epidemiological figure is limited to the Alps, in particular to the Northern side (Austria). Isolated cases have been reported also in Italy. TBE is a benign self-limiting illness that usually recovers without any reliquate. The laboratory diagnosis is obtained by isolating the virus in cell cultures from the CSF or blood of acute phase patients. Serology is anyway the main laboratory tool to perform this diagnosis. Complement fixation and EIA IgM are the most used methods: the latter technique is particularly sensitive in early infection.

[Human alveolar echinococcosis: an emerging zoonosis in Hungary and Europe].

Human alveolar echinococcosis, caused by the metacestode stage of Echinococcus multilocularis, is one of the most dangerous zoonoses in the temperate and arctic areas of northern hemisphere. The mortality of the disease exceeds 95% in untreated or inadequately treated patients. In the past three decades, the spread of this parasite was observed in Europe as a consequence of human interventions resulting in the population size increase of foxes. The authors demonstrated the presence of E. multilocularis in foxes in all northern counties of Hungary and the existence of hyperendemic regions in the Counties Nógrád and Gyor-Moson-Sopron. The aim of the present paper is to summarize the current knowledge on the life cycle and distribution of E. multilocularis, and the epidemiology, clinical features, diagnosis, treatment and control of human alveolar echinococcosis.

[Tuberculosis: a re-emerging zoonosis?].

Tuberculosis is an infectious disease that is found throughout the world and which can have a dramatic impact on the economy and on human and animal health. In humans, the principal cause of infection is Mycobacterium tuberculosis, but the animal-specific pathogen, M. bovis, is arguablythe most important zoonotic agent in human history. Despite the fact that several countries have implemented control programmes for M. bovis infection in animals, which has resulted in a reduction in the number of human cases as well, recent years have witnessed a re-emergence of tuberculosis. This is due to the appearance of strains that are resistant to the main antibiotics used to treat the infection in humans, the spread of the human immunodeficiency virus, the maintenance of wild reservoirs and the persistence of the infection in livestock, particularly in developing regions. Coordinated efforts by human and animal health services, the improvement of diagnostic techniques and the development of more effective vaccines to prevent the infection are the main strategies for controlling this disease.

[Ascariasis is a zoonosis in Denmark--secondary publication].

It has been claimed that Danish cases of human ascariasis have been acquired either during travel to other countries or through consumption of untreated food imported from areas where human ascariasis is endemic. An epidemiological survey in Viborg County indicated, however, that pigs are the primary source of the infection. Our population-genetic investigations have now confirmed this hypothesis. The main transmission route for human ascariasis in developed countries therefore seems to be from pigs to people; thus, it is essential that contact with pig manure be avoided, especially by young children.

Giardia, Cryptosporidium and the spectre of zoonosis: the Italian experience from land to sea.

In the last decade, a major concern for the scientific community has been whether infected animals can serve as reservoirs of Giardia and Cryptosporidium infection for humans. Worldwide, prevalence studies and molecular tools have provided insights into the taxonomy and epidemiology of these protozoa in order to better understand such a relation. This paper presents data on the prevalence and molecular genotyping studies from several sample types from land to sea (humans, companion animals, sheep, cattle, goats, wastewaters, surface water, and shellfish) available in Italy. The contribution of Italian researchers to the international debate on the veterinary significance of these infections and their impact on public health is highlighted and the main objectives to be pursued in the future depicted.

[West Nile virus--causative agent of a zoonosis with increasing significance?].

The epidemic West Nile Virus (WNV) infections observed in the last years, particularly those in the USA in 1999 and the following years, have led to an increasing interest in this zoonotic infection. Here, the most prominent aspects of WNV biology and epidemiology are presented. Clinical signs observed in men and horses are described, as well as the current state of diagnostics and immunoprophylaxis. Preliminary results of investigations on the prevalence of WNV in Germany show that migrating birds have been in contact with WNV; there is however no indication for the presence of this virus. While WNV is endemic in many parts of the "Old World", thus inducing "natural immunity" in (migrating) birds and vertebrates, a susceptible bird population with no existing immunity against this virus was exposed in the "New World".

[Chlamydia infections in sheep and goats. With a reference to its significance as a zoonosis].

Infections by Chlamydia psittaci are found worldwide in many species of mammal, including man, and birds. Small ruminants are affected mainly with abortion in the later phase of gestation. Additionally pneumonia and lesions in other organs can be observed. Pathological and clinico-epidemiological aspects of the infection with C. psittaci in small ruminants are described and discussed. The description of a case of conjunctivitis acquired by one of the authors through contact with infectious material alerts to the significance of C. psittaci as an agent able to cause zoonotic infections.

[Materno-fetal infection by Chlamydia psittaci transmitted by the goat: a new zoonosis?].

A case report is given of spontaneous abortion at 32 weeks brought about by Chlamydia psittaci following contact with a herd of goats. Severe symptoms were observed post-natally in this woman. Nine cases of materno-foetal infection with this pathogen are known, however, the source of infection is usually ewes suffering abortive chlamydiosis. Goats may also be infected, but caprine origin for the disease in pregnant women has not been reported previously.
