Última Human coronavirus ocurrence in different populations of Sao Paulo: a comprehensive nine-year study using a pancoronavirus RT-PCR assay BJM Cabeça,Tatiane K.; Passos,Ana Maria; Granato,Celso; Bellei,Nancy. Human coronaviruses (HCoVs) are considered one of the most common respiratory viruses associated with respiratory tract illnesses. An emergent human coronavirus was identified as the causal agent of an epidemic of severe acute respiratory syndrome (SARS) during 2002-2003. The severity of the disease combined with its rapid spread requires the continuous surveillance of coronaviruses in worldwide populations. Epidemiological and clinical data of HCoVs infectious in the Brazilian population are scarce and restricted to one or two groups of patients. Our study aimed to investigate retrospectively the presence of HCoVs in different populations of São Paulo presenting acute respiratory tract infections (ARIs) during the years of 2001-2010.

Abstract Background: Leptospirosis is an infectious and acute disease caused by Leptospira spp. that have high epidemic potential. This study verified the main Leptospira spp. serovars detected by MAT from serum of patients with suspicion of leptospirosis from 2008 to 2012 in Minas Gerais State. Methods: The laboratory received sera from 4654 patients. All serum were screened by IgM-ELISA according to the manufacturer's instructions. Each sample reactive or indeterminate were tested against twenty-four serovars of Leptospira by MAT. Results: In this study, 597 patients were classified as reactive on MAT. Only 301 patients were confirmed by laboratory test. It was not possible confirmation by laboratory diagnosis of 296 patients. Among the samples...

We analyzed cervical specimens of 202 women, aged 15 to 64 years, attended at Luis Antonio Hospital, Natal, Brazil, to determine the prevalence of HPV and identify the more frequent genotypes and risk factors for HPV infection in women attended at a cervical cancer screening service. Two specimens were collected from each patient: one for cytological examination and the other to detect HPV DNA by PCR, and typing by dot blot hybridization. A total of 54.5% of the sample had normal cytology and 45.5% had cytological alterations. HPV was detected in 24.5% of the cytologically normal women and in 59.8% of those with altered cytology. Both single and double HPV infection increased the likelihood of cytological alterations. Thirteen types of HPV were identified,...

Cervical cancer is an important health problem in women living in developing countries. Infection with some genotypes of human papillomavirus (HPV) is the most important risk factor associated with cervical cancer. Little information exists about HPV genotype distribution in rural and suburban regions of Mexico. Thus, we determined the prevalence of HPV genotypes in women from Tlaxcala, one of the poorest states in central Mexico, and we evaluated age infection prevalence and risk factors associated with cervical neoplasm. A cross-sectional study was conducted in 236 women seeking gynecological care at the Mexican Institute for Social Security in Tlaxcala, Mexico. Cervical scrapings were diagnosed as normal, low-grade, and high-grade squamous...

Bras. Ciênc. Avic. Meireles,MV; Roberto,LO; Riera,RF. There are few reports concerning the epidemiology of Eimeria praecox and Eimeria mitis in Brazil. In the present experiment, the polymerase chain reaction (PCR) was used to identify these species in 156 samples of broiler chicken feces from several Brazilian states and the Federal District. Oocysts present in feces samples were purified by sodium chloride flotation followed by addition of DNAzol reagent (Invitrogen®) for extraction of genomic DNA. DNA was precipitated and stored following DNAzol reagent manufacture's instructions. The primers and PCR conditions were as described by Schnitzler et al. (1999). In the 156 field samples analyzed by PCR, 70 and 45 were positive for E. praecox and E. mitis, respectively. In this study we have shown that DNA...

Pseudomonas aeruginosa is an important and frightening microorganism for patients suffering from cancer. Multiresistant P. aeruginosa (MRPA) may appear as a consequence of exposure to multiple antibiotics or from a breakdown in infection control practices. This article reports an MRPA outbreak in a cancer treatment centre and the consequent case control study. Mechanical ventilation was identified as being the main risk factor for developing MRPA colonisation or infection; molecular analysis confirmed the outbreak. A multifaceted strategy was adopted, involving reinforcing hand-washing practices, contact isolation, antibiotic restriction and suction devices for mechanically-ventilated patients. MRPA was controlled and the outbreak ended. Such strategy may...

Acute leukemia is the most frequent cancer in children. Recently, a new hypothesis was proposed for the pathogenesis of childhood acute lymphoblastic leukemia (ALL). The so-called "adrenal hypothesis" emphasized the role of endogenous cortisol in the etiology of B-cell precursor ALL. The incidence peak of ALL in children between 3 to 5 years of age has been well documented and is consistent with this view. The adrenal hypothesis proposes that the risk of childhood B-cell precursor ALL is reduced when early childhood infections induce qualitative and quantitative changes in the hypothalamus-pituitary-adrenal axis. It suggests that the increased plasma cortisol levels would be sufficient to eliminate all clonal leukemic cells originating during fetal life....

The USDA's National Animal Health Monitoring System (NAHMS) collected data on management practices and cow-calf herds as a source of family income from a representative sample of cow-calf producers from 23 of the leading cow-calf states. Overall, 2,713 producers with one or more beef cows participated in the NAHMS Beef '97 Study, representing 85.7 percent of the beef cows and 77.6 percent of the beef cow operations in the United States as of January 1997. Producers whose cow-calf herds were the primary source of family income were more productive than those whose herds were a supplemental source of income. Cow-calf herds were the primary source of income for 14 percent of the producers and provided supplemental income for 69 percent of the producers....

Laïd,Y; Boutekdjiret,L; Oudjehane,R; Laraba-Djebari,F; Hellal,H; Guerinik,M; Griene,L; Alamir,B; Merad,R; Chippaux,JP. Scorpion stings are a public health problem in the Maghreb region. In Algeria, epidemiological data were collected over the past twenty years by the Algerian health authorities. This study is an analysis of morbidity and mortality data collected from 2001 to 2010. Annual incidence and mortality due to scorpion envenoming were 152 ± 3.6 stings and 0.236 ± 0.041 deaths per 100,000 people (95% CI), respectively. The risk of being stung by a scorpion was dramatically higher in southern areas and central highlands due to environmental conditions. Incidence of envenoming was especially higher in the adult population, and among young males. In contrast, mortality was significantly higher among children under 15 years, particularly ages 1-4.

Plant Pathol. Oliveira,Andréia M. R.; Duarte,Valmir; Silveira,José R. P.; Moraes,Marcelo G.. Erwinia carotovora subsp. atroseptica (Eca), E. carotovora subsp. carotovora (Ecc) and E. chrysanthemi (Ech) may cause potato (Solanum tuberosum) blackleg. To determine the occurrence of these pathogens in the conditions found in the State of Rio Grande do Sul (RS), potato plants showing blackleg symptoms were harvested from 22 fields in nine counties in Serra do Nordeste, Planalto, Depressão Central, and Grandes Lagoas, from September to December of 1999 (Spring-Summer season). Green pepper (Capsicum annuum) fruits were used as a host to enrich for pectolytic erwinia from potato stems with blackleg symptoms. Bacteria were subsequently isolated on non-selective medium. Isolates that were Gram-negative, facultatively anaerobic, and pitted...

Epidemiological studies show that human papillomaviruses (HPV) are strongly related to cervical cancer and cervical intraepithelial neoplasias (CIN). Unlike the case for women, there are no consistent data on the natural history of HPV in the male population even though these viruses are prevalent in males. We carried out a prospective study to assess the prevalence of HPV in males as well as the factors that determine such infections in 99 male sexual partners of women with CIN. The genitalia of the males were physically examined and subjected to peniscopy for the collection of scrapings which were subjected to the polymerase chain reaction and restriction fragment length polymorphism to detect HPV. Of the 99 males sampled, 54 (54.5%) were positive for...

Emerging diseases pose a recurrent threat to bivalve aquaculture. Recently, massive mortality events in the Pacific oyster Crassostrea gigas associated with the detection of a microvariant of the ostreid herpesvirus 1 (OsHV-1 µVar) have been reported in Europe, Australia and New Zealand. Although the spread of disease is often viewed as a governance failure, we suggest that the development of protective measures for bivalve farming is presently held back by the lack of key scientific knowledge. In this paper, we explore the case for an integrated approach to study the management of bivalve disease, using OsHV-1 as a case study. Reconsidering the key issues by incorporating multidisciplinary science could provide a holistic under-standing of OsHV-1 and...

Development of aquaculture has been linked to zootechnical mastering of larval production in hatcheries. Regular and excessive use of antibiotics (antifungal or antibacterial) may thus also be reduced, permitting to limit release of these products in sea-water and, consequently, avoiding progressive selection of resistant-strains.

ABSTRACT Background: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is spreading worldwide, but little is known about the epidemiology of this pathogen in Brazil. Objective: To evaluate clinical and microbiological features of children with S. aureus infections admitted to a university hospital. Methods: This was a cross-sectional study evaluating the potential risk factors for CA-MRSA, and a retrospective cohort evaluating in-hospital clinical outcomes. To include patients with both community and hospital-associated infections, we screened the results of the microbiological laboratory tests from January 1, 2012, to December 31, 2016. According to the phenotype, we classified the isolates in Methicillin-Susceptible S. aureus...

Feline calicivirus (FCV) and feline herpesvirus type 1 (FHV-1) are the two primary causes of upper respiratory tract disease in cats. The aim of this study was to demonstrate the distribution of FCV and FHV-1 among the feline population of several counties in Rio Grande do Sul State, Brazil. To this end, conjunctival and nasal swabs were collected from 302 cats from different locations, including households, breeding catteries, veterinary clinics, animal hospitals and experimental research facilities. The samples were collected between July 2006 to June 2009. The virus isolation was performed in CRFK cells and, subsequently, the identification was confirmed by PCR.

Japanese encephalitis virus (JEV) causes Japanese encephalitis, which is a leading form of viral encephalitis in Asia, with around 50,000 cases and 10,000 deaths per year in children below 15 years of age. The JEV has shown a tendency to extend to other geographic regions. Case fatality averages 30% and a high percentage of the survivors are left with permanent neuropsychiatric sequelae. Currently, there is no cure for JEV, and treatment is mainly supportive. Patients are not infectious, but should avoid further mosquito bites. A number of antiviral agents have been investigated; however, none of these have convincingly been shown to improve the outcome of JEV.

We develop a dynamic model of livestock disease and decentralized economic behavior as a jointly-determined system. By accounting for feedbacks between behavioral choices and disease outcomes we capture the endogenous nature of infection risks. We consider government mandated testing of livestock herds and how private biosecurity incentives are affected by the structure of disease eradication polices. How well disease control policies are targeted affects their effectiveness and may result in farmers substituting government testing and disease surveillance for private biosecurity. Numerical simulation results demonstrate that failing to account for feedbacks between disease and economic dynamics may underestimate the level of infection. Not accounting for...

Bonamiosis, favoured by change of temperature and stress, causes mortalities in the adult flat oyster Ostrea edulis in the majority of European oyster farmers. The life cycle of this Haplosporidia protozoan Bonamia ostreae is unknown, it is not dttectable during the five mon th latent period. Because of the Jack of sensibility of reference techniques, histology and tissue smear, further use of PCR assays or HCM-CC, in particular, is recommended. Analysis of data collected in France from 1989 to 2004 shows the absence of simple prediction methods and an apparent cyclicity of the disease. Transfer restriction and control of boat hulls can protect uninfected areas. Reducing stress and density, commercialising earlier can limit losses in infected areas. The...

In 1985, red drum (Sciaenops ocellatus) was introduced in Martinique in arder to replace sea bass fish farming. Nodavirus antibodies were detected in the broodstock at the IFREMER station in Robert. Nodavirus is responsible for viral nervous necrosis, a disease that is spreading quickly in worlwide marine aquaculture. A biosecurity process was initiated at the Robert hatchery to select seronegative breeders and produce nodavirus free larvae. This process, based on a serological follow-up of fish antibodies by ELISA, allowed a reduction of the number of seropositive fish. A complementary serological study revealed a low incidence of nodavirus contamination in nodavirus free larvae placed in sea cages on different production sites Tipo: Text Palavras-chave: Nodavirus; Encéphalite virale; Sérologie; Ombrine subtropicale; Epidemiologie; Aquaculture; Nodavirus; Viral nervous necrosis; Serology; Red drum; Epidemiology; Aquaculture.
