Sporotrichosis: an emergent zoonosis in Rio de Janeiro

During the period from 1987 to 1998, 13 cases of human sporotrichosis were recorded at the Research Center Evandro Chagas Hospital (CPqHEC) in Rio de Janeiro. Two of these patients related scratch by a sick cat. During the subsequent period from July 1998 to July 2000, 66 human, 117 cats and 7 dogs with sporotrichosis were diagnosed at the CPqHEC. Fifty-two humans (78.8%) reported contact with cats with sporotrichosis, and 31 (47%) of them reporting a history of a scratch or bite. This epidemic, unprecedented in the literature, involving cats, dogs and human beings may have started insidiously before 1998.

Implantación del distintivo de garantía de calidad ambiental en hoteles de 3*, 4* y 5* de Sitges

Este proyecto tiene como objetivo estudiar la viabilidad de la implantación del Distintivo de Garantía de Calidad Ambiental (DGQA) en los hoteles de 3*, 4* y 5* del municipio de Sitges, perteneciente a la comarca del Garraf. El criterio de selección se ha basado en el estado del hotel (abierto o cerrado) en que se encontraba en el momento del estudio. Para conocer la gestión ambiental de los establecimientos hoteleros se llevó a cabo la realización de unas encuestas elaboradas a partir de los criterios requeridos por el DGQA, tanto obligatorios como opcionales. Los resultados obtenidos muestran un elevado cumplimiento de la puntuación obligatoria, así como la totalidad de los criterios opcionales requeridos. No se han detectado diferencias significativas entre las tres categorías hoteleras. Sin embargo, sí que aparecen diferencias entre los ámbitos propuestos por el DGQA, destacando el elevado cumplimiento en integración paisajística, ruidos y vibraciones, y diseño de espacios exteriores. Por el contrario se observa una carencia relevante en los ámbitos de compras y residuos. Finalmente se han propuesto las acciones de mejora necesarias para dicha obtención, obteniendo así un presupuesto aproximado para la consecución del distintivo por cada uno de los hoteles.

Triatomines Involved in Domestic and Wild Trypanosoma cruzi Transmission in Concepción, Corrientes, Argentina

An entomological and serological survey was performed in three localities of the Department of Concepción, Province of Corrientes, Argentina in 1998 and 1999, to identify triatomines species involved in domestic and wild transmission of Chagas disease. Triatomines were collected by man/hour capture in 32 houses randomly selected and 44 nearby outdoor ecotopes. Trypanosoma cruzi infection in triatomines was assessed by direct microscopic observation (400x) of feces and polymerase chain reaction. Serological techniques used for people were Indirect Hemagglutination Test and Indirect Fluorescent Test. Triatomines were collected in 28.1% of the houses and 31.8% of the wild biotopes. Triatoma infestans (Klug 1834) was exclusively found indoors and T. cruzi infected 60% of them. Triatoma sordida (Stål 1859) was mainly found in extradomestic ecotopes where trypanosome infection rate reached 12.7%. Serological study of 98 local people showed that 29.6% were seroreactive; most of their houses were closed to wild biotopes colonized by T. sordida. Results indicate that there is an active T. infestans mediated transmission of Chagas disease in this zone that yields important human prevalence and that the populations of T. sordida in wild biotopes not only sustain the wild T. cruzi cycle but also represent an actual risk for people living in the area.

An Autochthonous Case of Echinococcus vogeli Rausch & Bernstein, 1972 Polycystic Echinococcosis in the State of Rondônia, Brazil

The present case report refers to a patient from the State of Rondônia, North region of Brazil, attended with clinical suspicion of hepatic echinococcosis. Examination by imaging (ultrasonography and computerized tomography) revealed a conglomerate of cystic lesions, with mobile contents within the cyst. The serology (immunoblot) for Echinococcus sp. was positive (21 and 31 kDa bands). This case is the first reported in Rondônia, suggesting the need to investigate the polycystic echinococcosis in individuals with hepatic cysts from areas of tropical forest and hunting habits where wild life was present as wild dogs, cats and rodents, particularly Agouti paca (paca) and Dasyprocta aguti (agouti).

Rabies - it can be a fatal bite

Rabies is a preventable disease, but it kills up to 55,000 people each year. Therefore on World Rabies Day, 28 September 2011, the Public Health Agency wants to raise awareness and understanding about the importance of seeking medical advice on whether the country or countries people are visiting require vaccination against this serious disease.Rabies is transmitted to humans mainly by the bite of an infected animal (commonly a dog, but can be spread by other mammals including cats and monkeys). It can also be spread through a scratch, or by the animal licking a cut or a wound and saliva from the infected animal getting into the eyes, mouth or nose. It is impossible to tell just by looking at an animal if they are infected, therefore while visiting other countries it is best to avoid touching animals, especially strays.Dr Michael Devine, Consultant in Health Protection, PHA, said: "Rabies is an acute viral infection which is almost certainly fatal. The infection causes inflammation of the brain and symptoms usually start 2-8 weeks after exposure. Early symptoms include headache, fever and anxiety; progressing to acute pain, violent uncontrolled movements, spasms of the swallowing muscles making it impossible to drink and respiratory failure."People may be used to thinking about rabies when they go to more exotic locations like Asia and Africa, but it can also be present closer to home, such as in some eastern European countries. So it is always best to play it safe and avoid animals, especially strays."Dr Devine continued: "If you are bitten by an animal while abroad it is important to clean the wound thoroughly with soap and water and seek medical attention immediately, even if you have been previously immunised, as treatment must be given to attempt to reduce the risk of developing the disease - treatment works best if initiated as soon as possible. Rabies vaccination is very effective - almost 100%. Booster doses may be required after one year and then every 2-5 years for those at continued risk."

The frequency of Toxocara infection in mental retarded children

Human toxocariasis is commonly seen in places where stray and Toxocara canis-infected dog population is high. There is a strong correlation between frequency of Toxocara infection, life style, and infection risk. Institutionalization of mental retarded patients increases to risk of toxocariasis. In this study, we aimed at investigating the frequency of Toxocara infection among children with mental retardation not requiring institutionalization. The study included 96 cases, who had educatable mental retardation and 85 healthy subjects who comprised the control group. Anti-Toxocara IgG or IgM antibodies were investigated in all serum samples, using ELISA method. The frequency of Toxocara infection was found significantly higher in mental retarded cases than in those in the control group (18.8% and 7.1% respectively) (p < 0.05). There was no significant difference between mental retarded children and the control group in terms of mean age, age groups, gender, owning dogs and cats and duration of their ownership, socio-economic level and behavioural factors, and personal hygiene (p > 0.05). We did not find any significant difference between Toxocara seropositive and seronegative mental retarded children in terms of demographic factors and epidemiological factors that could increase the risk of Toxocara infection (p > 0.05). The present study is the first seroprevalence study carried out with a mental retarded group not requiring institutionalization. Determination of high frequency of Toxocara infection suggests that these subjects constitute a risk factor for Toxocara infection, which may be attributed to their behavioural patterns.

Human toxocariasis: a seroepidemiological survey in schoolchildren of Sorocaba, Brazil

A seroepidemiological survey for toxocariasis, among 180 schoolchildren of the public schools of Sorocaba City, state of São Paulo, Brazil, was carried out from August 2000 to July 2001. ELISA test was performed using excretory and secretory antigens for the detection of IgG anti-Toxocara antibodies. Information regarding the children was obtained from the parents or legal guardians. The results showed that the mean age was 5.4 ± 1.4 years, the infection coefficient (IC) was 38.3 and the infection risk was higher among the children living in the city outskirts (IC = 47.4) where the socioeconomic conditions were worse than in the central region of the city (IC = 11.1). There was an association between higher frequency of seroreactivity in the ELISA test and the condition of living in a house with a yard and/or unpaved street. The same was observed in relation to a history of enteroparasitism. There was also an association between a seronegative ELISA test and previous treatment of pet dogs and/or cats with vermifuge. Based on these results, the authors propose that public health programs should include anthelmintic for dogs and cats during the antirabies vaccination campaigns, in order to diminish environmental contamination with Toxocara spp. eggs and consequently human infection.

Enforced covalent trimerisation of soluble feline CD134 (OX40)-ligand generates a functional antagonist of feline immunodeficiency virus.

The feline immunodeficiency virus (FIV) targets activated CD4-positive helper T cells preferentially, inducing an AIDS-like immunodeficiency in its natural host species, the domestic cat. The primary receptor for FIV is CD134, a member of the tumour necrosis factor receptor superfamily (TNFRSF) and all primary viral strains tested to date use CD134 for infection. To investigate the effect of the natural ligand for CD134 on FIV infection, feline CD134L was cloned and expressed in soluble forms. However, in contrast to murine or human CD134L, soluble feline CD134L (sCD134L) did not bind to CD134. Receptor-binding activity was restored by enforced covalent trimerisation following the introduction of a synthetic trimerisation domain from tenascin (TNC). Feline and human TNC-CD134Ls retained the species-specificity of the membrane-bound forms of the ligand while murine TNC-CD134L displayed promiscuous binding to feline, human or murine CD134. Feline and murine TNC-CD134Ls were antagonists of FIV infection; however, potency was both strain-specific and substrate-dependent, indicating that the modulatory effects of endogenous sCD134L, or exogenous CD134Lbased therapeutics, may vary depending on the viral strain.

Identification of the best ovitrap installation sites for gravid Aedes (Stegomyia) aegypti in residences in Mirassol, state of São Paulo, Brazil

This study aimed at identifying the best ovitrap installation sites for gravid Aedes aegypti in Mirassol, state of São Paulo, Brazil. Ovitraps were installed in ten houses per block over ten blocks. Four ovitraps were placed per residence, one in the bedroom, one in the living room, and two outdoors with one in a sheltered area and one in an outside site. Each week for eleven weeks, visits were made to examine the ovitraps and to change the paddles used for egg-laying. Eggs were analyzed according to the trap location. The results showed that the outdoor sites received significantly more oviposition than indoor sites. Additionally, in respect to the outdoor sites, the outside site received significantly more oviposition than the sheltered site. A b correlation was observed between positive traps and egg numbers. The results are discussed with respect to the best installation site of the traps and their implications in surveillance and control of dengue vectors.

A survey on Triatoma dimidiata in an urban area of the province of Heredia, Costa Rica

Triatoma dimidiata has been found in several cities and towns of those countries where the insect is a domestic or peridomestic pest. In Central America, urban infestations occur in the capitals of at least five countries. During 2001 and 2002 a survey was carried out in the county of San Rafael, Heredia province, located 15 km northwest of San José, capital of Costa Rica, in order to determine the degree of infestation by T. dimidiata in an entire city block. Six peridomestic colonies of the insect were detected in the backyards of eight households. The ecotopes occupied by the insects consisted of store rooms with old objects, wood piles or firewood, and chicken coops. A total of 1917 insects were found in the six foci, during two sampling periods, and a mean infection rate by Trypanosoma cruzi of 28.4% was found in 1718 insects examined. The largest colony found in one of the households yielded 872 insects that were thriving mainly at the expenses of two dogs. Opossums and adult insects were common visitors of the houses and it became evident that this marsupial is closely related to the peridomestic cycle of the Chagas disease agent. Lack of colonization of the insect inside the human dwellings is explained by the type of construction and good sanitary conditions of the houses, in contrast to the situation in most peridomiciliary areas. Stomach blood samples from the insects showed that the main hosts were, in order of decreasing frequency: rodents, dogs, fowl, humans, opossums, and cats. The fact that no indication of infection with Chagas disease could be detected in the human occupants of the infested houses, vis a vis the high infection rate in dogs, is discussed.

Assessment of free-living physical activity in humans: an overview of currently available and proposed new measures.

The number of physical activity measures and indexes used in the human literature is large and may result in some difficulty for the average investigator to choose the most appropriate measure. Accordingly, this review is intended to provide information on the utility and limitations of the various measures. Its primary focus is the objective assessment of free-living physical activity in humans based on physiological and biomechanical methods. The physical activity measures have been classified into three categories: Measures based on energy expenditure or oxygen uptake, such as activity energy expenditure, activity-related time equivalent, physical activity level, physical activity ratio, metabolic equivalent, and a new index of potential interest, daytime physical activity level. Measures based on heart rate monitoring, such as net heart rate, physical activity ratio heart rate, physical activity level heart rate, activity-related time equivalent, and daytime physical activity level heart rate. Measures based on whole-body accelerometry (counts/U time). Quantification of the velocity and duration of displacement in outdoor conditions by satellites using the Differential Global Positioning System may constitute a surrogate for physical activity, because walking is the primary activity of man in free-living conditions. A general outline of the measures and indexes described above is presented in tabular form, along with their respective definition, usual applications, advantages, and shortcomings. A practical example is given with typical values in obese and non-obese subjects. The various factors to be considered in the selection of physical activity methods include experimental goals, sample size, budget, cultural and social/environmental factors, physical burden for the subject, and statistical factors, such as accuracy and precision. It is concluded that no single current technique is able to quantify all aspects of physical activity under free-living conditions, requiring the use of complementary methods. In the future, physical activity sensors, which are of low-cost, small-sized, and convenient for subjects, investigators, and clinicians, are needed to reliably monitor, during extended periods in free-living situations, small changes in movements and grade as well as duration and intensity of typical physical activities.
