A study of the lesions beaked whales (BWs) in a recent mass stranding Canary Islands following naval exercises provides possible explanation relationship between anthropogenic, acoustic (sonar) activities and death marine mammals. Fourteen BWs were stranded close to site an international exercise (Neo-Tapon 2002) held on 24 September 2002. Strandings began about 4 hours after onset midfrequency sonar activity. Eight Cuvier's (Ziphius cavirostris), one Blainville's BW (Mesoplodon...
The interactions among hepatitis B virus (HBV), C (HCV), and delta (HDV) were studied by measuring HBV–DNA HCV–RNA levels determining the influence of viral genotypes mutations in HBV basal core promoter (BCP) precore regions. We included 65 consecutive patients, 25 HBV/HCV, 18 HBV/HDV, 22 HBV/HCV/HDV. Controls consisted 55 patients with chronic HCV infection. lower coinfections than single infections ( P < .05). HBV/HCV coinfection was associated viremia (8.2 × 10 4 copies/mL) (7 5...

Porcine enzootic pneumonia (PEN), caused by Mycoplasma hyopneumoniae (Mh), has been described in pigs all geographic areas. The disease is characterized high morbidity and low mortality rates intensive swine production systems. A morphologic immunohistochemical study was done to determine the cellular populations present lung parenchyma of infected pigs, with special attention bronchus-associated lymphoid tissue (BALT). Polyclonal monoclonal antibodies were used for detection antigens Mh, T...
Abstract It has been proposed that olfactory tests and metaiodobenzylguanidine cardiac scintigraphy may help diagnose idiopathic Parkinson's disease in the premotor phase. However, it is not clear what value these have all patients with and, particularly, those who carry mutations LRRK2 . The objective was to analyze dysfunction changes I‐metaiodobenzylguanidine uptake carrying R1441G G2019S , no known mutations. Patients were screened for gene classified as mutation carriers or noncarriers....
Human rhinoviruses (HRVs) belong to the Picornaviridae family with high similarity human enteroviruses (HEVs). Limited data is available from Latin America regarding clinical presentation and strains of these viruses in respiratory disease. We collected nasopharyngeal swabs at clinics located eight American countries 3,375 subjects aged 25 years or younger who presented influenza-like illness. Our had a median age 3 1.2:1.0 male:female ratio. HRV was identified 16% HEV 3%. HRVs accounted for...
Eimeria christenseni is considered among the most pathogenic species in goats. The aim of this study was to isolate an E. strain and assess its infectivity, pathogenicity, ability develop a protective immune response. After previous collection christenseni-positive faeces, purification oocysts, amplification donor animals, experimental infection carried out. A total 19 kids were divided into three groups: primary-infected challenged, challenge control, uninfected control. Infections...
Forty-seven feline and 60 canine epithelial tumors were studied to test the coordinate expression of cytokeratin 7 (CK 7) 20 20) using commercially available monoclonal antibodies an avidin-biotin immunoperoxidase staining technique. Previously, distribution both cytokeratins was examined in normal tissues from 4 cats dogs. The pattern CK similar, with minor differences, that described humans, whereas reactivity dogs wider than humans. subset strongly expressing included pancreatic...
A sensitive and accurate HBV DNA quantification assay is essential for monitoring hepatitis B virus (HBV) replication. This study evaluated a real‐time PCR method performed in the LightCycler TM analyser quantitative assay. results with this were compared those obtained using branched‐chain (bDNA) solution hybridization Real‐time was two adjacent fluorescently labelled probes primers corresponding to core gene. The same standard employed bDNA used calibration. Serum samples came from 193...
We describe two reliable methods for high-throughput screening of proteinase inhibitor (PI) S and PI Z α1-antitrypsin (α1-AT) deficiency alleles from dried blood spot (DBS) specimens using the LightCycler fluorimetric analyzer. The method was used to study 72 patients with chronic obstructive pulmonary disease. Results were confirmed DNA sequencing. α1-AT concentration in DBS determined immune nephelometry. Sixteen (22%) showed no or mutations. Five (7%) had a heterozygous genotype...
Despite the disease burden imposed by respiratory diseases on children in Central America, there is a paucity of data describing etiologic agents disease.To analyze viral associated with influenza-like illness (ILI) participants reporting to one outpatient health center, pediatric hospital, and three general hospitals El Salvador, Honduras, Nicaragua Material &Between August 2006 April 2009, pharyngeal swabs were collected from outpatients inpatients. Patient specimens inoculated onto...
To determine which clinical or laboratory criteria best reflected the prognosis for 83 children with acute hematogenous osteomyelitis (AHO), they were compared outcomes after a follow-up of at least 2 months (for 78%, ≥6 months). Twenty-eight (34%) developed sequelae. They had higher serum C-reactive protein (CRP) concentrations (days 1–6 treatment; P = .0004 to .0001) and scores (P than did patients who an uneventful recovery. The frequency sequelae increased from 3% 73% when CRP exceeded...
Ten spontaneous mammary gland tumors affecting guinea pigs (GP) were analyzed histologically and immunohistochemically. Histologically, 3 benign (2 simple adenomas 1 mixed tumor) 7 malignant (1 solid carcinoma 6 tubulopapillary carcinomas). Immunohistochemical data revealed the glandular immunoprofile of all suggested their ductal origin on basis cytokeratin 20 expression. Interestingly, was detected in basal/myoepithelial cells. Further, positive for type alpha estrogen progesterone...
Mycoplasma hyopneumoniae (Mhy) is the causative agent of enzootic pneumonia, characterized by high morbidity and low mortality rates in intensive swine production systems. To better understand mechanisms underlying protection an inactivated whole cell vaccine, we investigated immunohistochemical differences cytokine expression vaccinated non-vaccinated pigs experimentally infected with Mhy. Four-week-old Mhy-negative (n = 24) were allocated to negative control 8), or one two Mhy-infected...
