OBJECTIVES: to determine the entomological contribution of these water tanks -widely distributed containers at community setting- to infestation by Aedes aegypti in an urban health area of Camagüey province. METHODS: Out of the total number of containers positive to Aedes aegypty, the amount of water tanks involved was estimated, in order to determine the specific container rate (sCR) together with the average of pupas per positive water tank on the ground. These tanks were characterized during the study of the house using an application form prepared to this end. Similarly, the average total number of hours that the tanks remained uncovered was estimated. RESULTS: It was found that 36.03 % of all positive containers were water tanks on the ground, which were mostly filled with water from the aqueduct outdoors; being the sCR = 2,69. Over 97% of them had faulty covers whereas 92.5% remained uncovered for 6 or 7 hours a day. Seventeen positive tanks sheltered 41 pupas for an average of 2.41 pupas per tank. CONCLUSIONS: The contribution of water tanks on the ground to the presence of Aedes aegypti pupas in the area makes it necessary to give priority to the inspection and surveillance of such containers on the part of the population and the expert staff The supply of new covers will not represent the final solution to this problem if the behaviour of the dwellers in a house does not change. It is required to improve the information to be provided to the population so that the risk perception is changed and the level of knowledge on this topic is raised. In this way, it will be possible to involve the community more actively in this process as a key element to make it really sustainable.

It also elucidated their complex structure and function that have served at a given time as methodological basis for creating unimaginable paradigms such as fine recognition specificity, and also for destroying other apparently immutable ones as invariability and universality of the cellular genome. A review was made of the evolution of antigen-antibody reaction-based analytical systems up to the present, the situation of infectious diseases and the determining role that detection and monitoring of infectious agents play in their control. The extraordinary capability of antibodies to discriminate antigenically similar structures allows them to be fundamental tools in immunoassays and also in a well-established discipline at present, that is, immunotechnology.

METHODS: review of the case of a young man suffering moderate allergic reaction to ant stings and comments on the biomedical importance of this event. This is the second accident described in literature and associated with Odontomachus bauri ant, which stresses its epidemiological weight in the future. The clinical signs and symptoms of an allergic reaction together with some biological aspects of the ant were described. The patient was treated with hydrocortisone sodium succynate (100 mg/stat) and systemic antihistaminic drug Loratadina. CONCLUSIONS: allergic reactions as a result of hymenoptera stings is becoming a growing problem in many countries; therefore it is essential that the medical authorities be aware of the dermatological and systemic manifestations affecting some patients stung by ants.

OBJECTIVES: to evaluate the feasibility in the administration of rapid epidemiological surveys for some aspects of sputum smears collection and quality in respiratory symptomatic TB suspects. METHODS: a previously expert-validated questionnaire was administered to people with respiratory symptoms from January to February 2006 in ten municipalities of Ciudad de la Habana province. For the selection of the respiratory symptomatic suspects, a three-phase cluster sampling was performed. RESULTS: the survey was well accepted by the study population which provided the requested data. Cough persisted for 15,3 days; 87,1% of sputum smears were taken early in the morning and 80% of the studied people considered it as good. CONCLUSIONS: these findings are acceptable and important for TB surveillance and control in this province and show the usefulness of these surveys.

Most of the o...INTRODUCTION: histoplasmosis, an infection caused by Histoplasma capsulatum fungus, is considered as one of the main endemic infections in the American continent where there are frequent epidemic outbreaks. Most of the outbreaks have been associated to risky activities in bat-inhabited places. This paper presented two outbreaks of occupational acquired histoplasmosis occurred in La Habana province. METHODS: one hundred and sixteen workers, who performed aerosol-generating tasks in caves, were studied. Samples from the cave soils were taken to assess the existence of the causal agent. Clinical and epidemiological data were gathered for the outbreak characterization. RESULTS: the rates of infection for both outbreaks were 60 % and 78 % respectively. The patients aged 16 to 64 years; additionally, the onset of main clinical manifestations (fever, general malaise, cough, headache, loss of weight, and chest pain) ranged from 10 to 20 days. Histoplasmosis was microbiologically and serologically diagnosed whereas its source of infection was confirmed through H. capsulatum isolation in those places where extensive excavation work had been carried out, resulting in abundant aerosols for up to 21d periods. The similarity between the two outbreaks was the performance of aerosol-generating tasks in risky places without using appropriate safety devices. CONCLUSIONS: It is necessary to disseminate the existing preventive measures among the health care staff and the risky groups as well as the general population in order to prevent and take control of possible histoplasmosis outbreaks in the future.

OBJECTIVE:...INTRODUCTION: malaria was eradicated in Cuba in 1967; however, the intensification of this disease worldwide and the huge flow of people from endemic areas make the re-introduction of malaria in Cuba possible. OBJECTIVE: to detect the presence of Anopheles albimanus (main malaria vector) in permanent and temporary breeding sites in a municipality of the City of Havana, Cuba. METHODS: the research study was undertaken in Boyeros municipality in 2008. The sampling frequency was weekly. The permanent breeding sites under study were dams, natural lagoons, oxidation lagoons, ditches, absorbing wells, activation ditches, Inhoff tanks, streams and rivers whereas ponds were considered as temporary reservoirs. RESULTS: a total number of 466 sites were positive to An. albimanus. The highest number of breeding sites was located in Mulgoba with 114 and the lowest figures went to Capdevilla with 30; November was the months exhibiting the highest number of positive breeding sites with 72 whereas April was the month having the lowest quantity (16). Similar values were found in the number of breeding sites in the two seasons of the year (dry and rainy) with 234 and 232 respectively. CONCLUSIONS: Anopheles albimanus were found in permanent breeding sites located in Boyeros municipality in all areas and throughout the whole year; therefore, being on the alert must be a priority action in the surveillance system of malaria in this municipality.

OBJECTIVES: to determine the protective efficacy of Heberbiovac HB vaccine at different dosage in physically and mentally-handicapped children after 14 years of the primary vaccination schedule. METHODS: in 1991, an effectiveness study of vaccine Heberbiovac HB was conducted in 2 groups of physically and mentally-handicapped (A = 10 microg y B = 5 microg). The study was approved by the Committees of Medical Ethics and Revision of "Pedro Kouri" Tropical Medicine Institute and of the Center of Genetic Engineering and Biotechnology of the City of Havana; good clinical practice were followed and the ethical principles of Helsinki Declaration were respected for. The vaccination schedule at 0, 1 and 6 months was used in which children negative to hepatitis B virus surface antigen and to hepatitis B virus surface antigen antibody were included. The subjects were studied from the clinical and serological viewpoints up to 14 years after the implementation of the aforementioned vaccine schedule. RESULTS: one year after the beginning of the vaccination, there was full seroprotection in both groups. After 14 years of follow-up, none of the subjects was positive to hepatitis B virus surface antigen, neither were they affected by acute hepatitis B, which meant 100 % individual protection. CONCLUSIONS: the immunogenic power of Heberbiovac HB vaccine was high and its protective efficacy was 100% in physically and mentally-handicapped children according to the results of the clinical and serological follow-up extending up to 14 years after the implementation of the primary vaccination schedule. These results are achieved for the first time for this kind of vaccine.

Rapid and accurate identification of yeast has become relevant not only for the effective management of infections, but also for the prevention of drug resistance. Up to now, yeast identification procedures are based on a variety of tests, including their ability to use sugars. OBJECTIVE: the purpose of the study was to evaluate a modified auxonographic procedure with the use of carbonated compounds for the rapid identification of Candida species within 24 to 48 h. METHODS: the new procedure is based on the carbohydrates assimilation (auxonograph) and was developed and evaluated for the identification of the most clinically relevant Candida species. A total number of 164 Candida species strains were included in the study, 156 of them were isolated from clinical specimens and other 8 reference strains from the central culture collection of BioCen (C. albicans, C. tropicalis. C. parapsilosis, C. glabrata, C. guilliermondii, C. krusei y C. kefyr). The new methodology was based on the use of standardized yeast suspension of carbon-free culture medium sterilized by autoclaving. After gelling the mixture (60 mL of cultural medium and 3 mL of microbial suspension), 10 microL of different carbohydrate filtering-sterilized solutions were dispensed at different points of the culture medium surface. The carbohydrate uptake was seen as a growth zone around the carbohydrate point of distribution after 24-48 h of incubation. RESULTS: all Candida species were correctly identified by the modified auxonographic method and 100 % agreement with the Wickerham technique was achieved. CONCLUSIONS: the alternative method for the auxonographic carbon test is simple, reliable, faster and easier to interpret than the Wickerham method.

OBJECTIVE: to detect the presence of pathogenic types of DEC in children attending the Health Centers in poor neighborhoods in the city of Corrientes, Argentina. METHODS: Feces from one hundred and twenty patients were cultured; E. coli isolates were selected in those cases negative for Salmonella or Shigella, and they were studied by multiplex PCR in order to characterize the pathogenic types of DEC. RESULTS: one hundred and twelve patients were included. All of them had urban housing with drinking water supply and toilet. In 41 samples (37%) some DEC type was detected but none of them (STEC 7, EPEC 7, EIEC 7, EAEC 10, and ETEC 10) was predominant. There were not significant differences between the DEC pathogenic types and the sex or the age group of patients. CONCLUSIONS: DEC is frequent etiologic agent in children and the recognition of each pathogenic type will allow implementing prophylactic measures according with its epidemiology.

METHODS: with prior informed consent given by the dermatologists from the City of Havana, 50 dermatologists- a number very close to the universe of these experts in the province- were administered a survey of their knowledge, perceptions and practice about this parasitosis. The survey was prepared in 4 phases; that is, interviews to physicians on diagnosis, treatment and control of giardiasis; drafting of a preliminary questionnaire based on the interview results; submission of this instruments to the experts, and finally its validation through its application to a small group of physicians. RESULTS: it was evinced that the dermatologists in the City of Havana had poor knowledge about giardiasis, particularly its cutaneous manifestations (out of 19 questions on cognitive aspects, the correct answer mean was 10,18), inadequate perceptions on this disease and practice was not good. CONCLUSIONS: with the aim of mitigating these difficulties, some academic intervention is needed to make emphasis on the formative aspects related to parasitic diseases in general and giardiasis in particular

Jaundice and dark urine are frequent signs that can alert to the occurrence of severe malaria. OBJECTIVE: to study the relationship between jaundice and dark urine with impaired liver and/or kidney function and anemia in malarial patients, and explore their role as warning signs. METHOD: clinical and laboratory data from 199 patients with Plasmodium falciparum malaria, belonging to a case control study conducted in Colombia, were analyzed, the association between dark urine and jaundice with impairment in the urine analysis, the hepatic and renal function test, and hemoglobin were studied. RESULTS: there was association between dark urine and hemoglobinuria (OR = 236, 63-867), hematuria (OR = 3.2, 1.6-6.6), proteinuria (OR = 2.3, 1-5.3) and bilirubinuria (OR = 2.1, 1-4.4). Jaundice was present in 31 % of patients who had renal dysfunction (OR = 2.7, 1.1-6.4) and in 22 % of those with liver dysfunction (OR = 2.1, 0.9-4.5). Jaundice was more likely in patients with total bilirubin > 25.6 micromol/L (OR = 6.1, 2.7-13.4) and blood ureic nitrogen > 7.14 mmol/L (OR = 3.5, 1.4-8.5). CONCLUSIONS: jaundice in patients with malaria may be considered as a warning sign associated with liver and kidney dysfunction. Dark urine was not associated with kidney or liver dysfunction, but was related to bilirubinuria, hematuria and proteinuria, which can be early indicators of failure; dark urine must be studied to clarify its relationship with liver and kidney failure in malaria.

The different methods of processing and diagnosis make it difficult to determine the most effective and sensitive technique. OBJECTIVE: a comparative analysis of parasitological technique sensitivity in vegetable samples. METHODS: a total of 30 samples were harvested -lettuce (Lactuca sativa), rocket (Eruca sativa) and watercress (Nasturtium officinale)--and later analyzed using Hoffman, Pons, and Janer (HPJ) and Faust (f) techniques. Data were analyzed, using the Bland-Altman test to evaluate the correlation and the Mann-Whitney test to compare the medians. RESULTS: of the analyzed samples, 46.6% were positive for intestinal parasites; Balantidium coli, accounting for 20% of contamination, Entamoeba coli (21.6) and Entamoeba histolityca (5%), Trichuris trichiura (3.3%) and Strongyloides stercoralis (2.5%) The Bland-Altman test showed significant correlation between the analyzed methods. When evaluating the averages separately, there was significant difference (p = 0.05) among the results. CONCLUSIONS: this study proved that the HPJ technique was more effective for the detection of eggs, helminth larvae and protozoan cysts in the plants under study.

OBJECTIVES: to determine the relative abundance of populations and the possible use of some species as biological control agents against F. hepatica intermediary hosts. METHODS: a total of 13 freshwater bodies were sampled during March and November, 2008 using Capture by effort unit method to capture the mollusks RESULTS: thirteen mollusk species (12 gastropods and 1 bivalve) were found after sampling. The relative abundance of species varied in different types of habitat. The intermediary host species of fascioliasis were dominant in two sites. Fossaria cubensis was dominant in Canal de la Entrada despite the presence of Melanoides tuberculata. The specie Pseudosuccinea columella was more abundant in Los Mangos. In La Presa del Matadero y Las Palmas despite the presence of these species, the prevailing ones were Physa acuta and some planorbids. CONCLUSIONS: the sites where intermediary hosts of Fasciola hepatica predominated were identified through data on the distribution and relative abundance. In some sites Melanoides tuberculata was present and acted as a biological control agent but it did not in others. Therefore, an evaluation on using a different thiarid would be useful to control these species.

METHODS: two years--2005 and 2006--were analyzed through 2 samplings per years covering the rainy and the dry season; 20 reservoirs were sampled to determine the present freshwater mollusks. Data were processed by Excelxp and the statistical analysis used SPSS version 8 processor and 4 x 4 contingency tables. RESULTS: ten species were detected in 2005, being Tarebia granifera the most distributed and abundant followed by Marisa cornuarietis. It was observed that the highest amount of mosquitoes was collected in the rainy season during the two years under study in addition to proving that there was significant correlation between the occurrence of mollusk species and fish in the 20 researched reservoirs. CONCLUSIONS: Yaguajay municipality exhibits wide freshwater mollusk fauna if one takes into account the 14 identified species of which 4 turned out to be intermediate hosts for fascioliasis, schistosomiasis and angiostrongyliasis. There is close relation between freshwater malacofauna and vegetation.

OBJECTIVES: to determine the behavior of Aedes aegypti mosquitoes depending on season and weather conditions and how it relates with climatic factors such as temperature and rain. METHODS: a descriptive seasonal and weather study was made on the basis of data given by the provincial weather center and the surveillance anti-vector fight unit located in Sancti Spiritus province, which covered the 1999-2007 period. RESULTS: of the total number of samples, 86.7% comprised immature phases of the mosquito whereas 13.2% corresponded to mosquitoes at the adult phase; 19.2% of foci were found inside houses and premises but 80.7% outdoors. The highest focal incidence occurred in 2001 (278 foci) and in 2005 (219 foci) whereas the lowest incidence was found in 1999 (14 foci) and in 2003 (32 foci). The municipalities with the highest numbers of foci were Trinidad (302), Sancti Spiritus (242), Cabaiguán (241) and Jatibonico (154) and the lowest figures went to Yaguajay (13) and La Sierpe (6). The number of foci in the rainy season was significant with respect to the dry season (t = 4.09; p = 0.04). There was not high correlation between the number of foci and the recorded temperatures in the course of the study. CONCLUSION: it was shown that keeping permanent surveillance on Aedes aegypti is extremely important to prevent introduction and spread of this species into the province, mainly in the rainy periods.

On the microscopic study, the samples taken from the patient during her admission corresponded to epithelium and hair. The skin biopsy was interpreted as exulceration secondary to scratching, and no evidence of parasites was found. Psychological and psychiatric evaluation of the patient confirmed her hallucinatory state. She was finally diagnosed a Delusional Parasitosis (II grade Primary Dermatozoal Parasitic Delirium, ectoparasitosis). This is a very infrequent diagnosis and no documented case was found of this dermatological pathology in Cuba.

Within this group of infections, the meningitis caused by Pseudomonas sp is rare. The case of a 54-year-old patient with a clinical picture of meningitis is reported. Pseudomonas aeruginosa was isolated from the cerebrospinal fluid. The meningitis caused by Pseudomonas aeruginosa should be taken into consideration because of the severity of the clinical picture and the high mortality and increasing strain resistance.

The viral gastrointestinal diseases are common but they rarely produce a severe disease. Recent investigations show that Norwall-like virus (Noro-Virus) is the most frequent gastrointestinal pathogen in Central Europe. The etiological diagnosis of the gastrointestinal disease, starting from autopsy material, was only possible by polymerase chain reaction. The introduction of this technique allowed to reduce the number of cases of gastrointestinal diseases without etiological diagnosis and, at the same time, to increase the demonstration of the occurrence of infection caused by Norwalk-like virus.

For each experimental unit, one hundred second instar larvae of this mosquitoe were infested with preparasites of the three nematode species in the following proportions: 3:1, 5:1, 10:1, 15:1 and 20:1. Both infestation mean and parasitism rate increased as the doses augmented. Romanomermis culicivorax proved to be more effective at low doses when compared to other species; however, with the 10:1 proportion, all the nematodes caused 100% of mortality. S. spiculatus showed the highest infestation rate. For this reason, a proportion of 10:1 could be recommended to evaluate these nematodes under natural conditions in useless artificial containers as a biological alternative for Aedes aegypti control.
