Título: Screening thoroughbreds for antibodies to the Equine infectious anemia virus.
Fonte: West Indian veterinary journal;5(1):6-9, November 2005. tab, ilus.
Idioma: en.
Resumo: One hundred and seventy two Thoroughbreds were screened for the presence of anitbodies to the capsid protein, p26 of the equine infectious anemia (EIA)virus using agarose gel immunodiffusion (AGOD) Coggins test. Horses ranged in age from 1 month to 21 years old and were either imported or locally bred. The majority were involved in racing and breeding and were housed either at the Santa Rosa Racing Complex at Arima or at privately owned farms. Complete blood counts (CBCs) were performed on all horses. Low haemoglobin concentrations were found in 18(10.5%), high white blood cell counts in 17 (9.9%) with neutrophilia in 13 (7.6%). Low red blood cell counts were seen in 11 of 154 horses (7.1%). At least 12 horses had evidence of clinical babesiosis, but only 7 were confirmed infected by examination of Giemsa stained blood smears. Racehorses from trinidad and Tobago occasionally move inter-island for racing and increasingly come in contact with foreign horses with the increasing importation of horses from countries known to harbour the virus. All 172 horses tested negative for antibodies to EIA virus. This implies that the strict adherence to import and quarantine regulations may have contributed to keeping the country free from EIA virus. This ongoing study is the first to provide sero-prevalence data and document the prevalence of EIA in the equine population in Trinidad and Tobago.

Título: Trends in the patterns of IgM and IgG antibodies in febrile persons with suspected dengue in Barbados 2006-2013
Fonte: In: Caribbean Public Health Agency. Caribbean Public Health Agency: 60th Annual Scientific Meeting. Kingston, The University of the West Indies. Faculty of Medical Sciences, 2015. p.[1-75]. (West Indian Medical Journal Supplement).
Idioma: en.
Resumo: OBJECTIVES: To describe the seroprevalence of dengue antibodies in febrile suspected persons and investigated for dengue in this country. DESIGN AND METHODS: This was a retrospective population based study of all febrile children and adults with probable dengue from 2006 to 2013. Persons with probable dengue were investigated for dengue IgM and IgG antibodies in the blood sample drawn between days 3 to 5 of their illness. RESULTS: Among the 8296 cases that were tested for IgM antibodies, 2605 (36.6%) cases tested positive. Of the 7227 suspected cases who were tested for IgG, 5473 (75.7%) were positive. During the study years, between 80% and 90% of persons older than 20 years had a positive IgG antibody. Among the persons younger than five years (excluding the first year), between 10% and 20% had a positive IgM titre and a negative IgG titre, between 5 and10% had a positive IgM and IgG titre, 5% had a positive IgG titre and a negative IgM titre and between 45% and 65% had a negative IgM and a negative IgG titre. Between 37% and 59% had a serological evidence of past dengue in absence of any current dengue. CONCLUSIONS: The pattern of IgG antibodies seen in this study was comparable to those seen in the countries known to be hyperendemic for dengue. Based on the pattern of antibodies, the age of infection was likely to shift down to younger age groups with the likelihood of more severe forms of dengue in the future.

Título: Serological epidemiology of poliomyelitis on St. Vincent Island, Federation of West Indies
Fonte: Am J Trop Med Hyg;10(4):579-82, July 1961.
Idioma: En.
Resumo: Sera collected from 152 healthy young inhabitants of the island of St. Vincent (Population, about 80,000) were assayed for antibody against all three types of poliovirus. Results showed that, in spite of the fact that the island has never had an outbreak of poliomyelitis, a significant part of the population develops antibodies to each of the three types of poliovirus by the age of 5 years, and this increases to involve 86 to 95 percent of the young adult population. Evidence indicates that at present St. Vincent is part of a Caribbean zone of poliomyelitis endemicity. But as clinical poliomyelitis is appearing with increasing frequency in other parts of this zone, vaccination of susceptible young children on St. Vincent should be considered in order to anticipate, and prevent, a shift to the epidemic situation.(AU)

Título: Age-dependency of infection status and serum antibody levels in human whipworm (Trichuris trichiura) infection
Fonte: Parasite Immunol;13(6):629-38, Nov. 1991.
Idioma: En.
Resumo: This study examines the age-dependency of the relationships between human infection with whipworm (Trichuris trichiura) and parasite-specific antibody level measured by ELISA against an extract of adult worms after preincubation of the sera with Ascaris lumbricoides adult worm extract. The convex age-profile of parasite infection intensity is shown to be mirrored by age-dependent change in age-class mean levels of IgG (all subclasses except IgG3), IgA, IgM and IgE. Mean antibody levels rise with increasing acquisition of infection in childhood. Immunoblot analysis of selected sera from different age-classes indicates that antigen recognition is similarly dependent on infection intensity. In individual children, antibody levels correlate positively with acquisition of infection, consistent with a simple model of antigen dosage specifying the magnitude of the humoral immune response. In adults, IgG4 correlates positively and IgA negatively with intensity of infection, suggesting involvement of these isotypes in functional roles of immune blockade or effector mechanisms, respectively.(AU)

Título: Relationship of acute rheumatic fever to acute glomerulonephritis in Trinidad
Fonte: J Infect Dis;125(6):619-25, June 1972.
Idioma: En.
Resumo: The incidence of acute rheumatic fever decreased during a major epidemic of acute glomerulonephritis in Trinidad in 1965. Subsequently, several minor increases in the incidence of acute rheumatic fever have been coincident with more marked increases in the incidence of acute glomerulonephritis. The relation of streptococcal infections to acute glomerulonephritis has been studied in Trinidad for the past six years. Their relation to acute rheumatic fever also has been examined during the last year of these studies. The streptococcal strains isolated from patients with acute rheumatic fever generally have differed from those found in patients with acute glomerulonephritis. Moreover, while streptococcal skin infections have been associated with acute glomerulonephritis, no such association has been apparent with rheumatic fever. However, titers of antistreptolysin O were relatively low, while titers of antihyaluronidase were makedly increased in the patients with acute rheumatic fever, much as they have been in most patients with acute glomerulonephritis in Trinidad (AU)

Título: Neutralizing antibodies against certain viruses in the sera of residents of Trinidad, B. W. I
Fonte: Am J Trop Med Hyg;5(4):626-41, July 1956.
Idioma: En.
Resumo: Blood samples taken from 1,055 indigenous residents of Trinidad B. W. I., were tested for neutralizing antibody against 17 different viral agents known or believed to be arthropod-borne, in 4,555 protection tests. Yellow fever, Ilheus and dengue are, or have been, on the basis of protection tests, presumably present, widespread, and common in Trinidad. A yellow fever outbreak occurred during the course of investigation in 1954. There is no evidence that Venezuelan equine encephalitis has been present on the island since the last reported outbreak in 1943. A small number of sera were found which neutralized St Louis encephalitis virus. No interpretation of this result is attempted. Although no human sera neutralized Eastern equine encephalitis virus, two different specimens of serum from one donkey neutralized the virus in two different tests. Interpretation of tests against Uganda S, West Nile, Semliki, Ntaya, and Japanese B is complicated by the possibility of interfering cross-immune reactions. All tests with Bwamba, Zika, Anopheles A, Western equine encephalites, and Bunyamwere viruses were negative. A provisional ecological zoning of the island is presented, based upon distribution of immunity against several viral agents (Summary)

Título: Leptospirosis in patients from Grenada, West Indies
Fonte: Trans R Soc Trop Med Hyg;73(3):303-5, 1979.
Idioma: En.
Resumo: Evidence of leptospirosis in humans from Grenada, W.I., is reported here for the first time. Of 139 hospital patients with pyrexia of undetermined origin, 94 were jaundiced, and 16 (17 percent) of these were positive for hepatitis B antigen (HBsAg) and not examined further. 20 of the remaining 123 (16 percent) febrile patients were positive for leptospiral antibodies; 11 of them were current or recent cases. 25 of 182 (14 percent) afebrile out-patients showed evidence of previous exposure to leptospiral organisms. The most frequently encountered serogroups in the 45 seropositive in- and out- patients were Icterohaemorrhagiae (38 percent) Panama (24 percent) and Canicola (11 percent) (Summary)

Título: Application of the enzyme linked immunosorbent assay (ELISA) for the serodiagnosis of Schistosoma mansoni infections in St. Lucia
Fonte: Trans R Soc Trop Med Hyg;73(6):636-9, 1979.
Idioma: En.
Resumo: As part of our search for a serodiagnostic assay to replace the expensive and tedious stool examination in the diagnosis of Schistosoma mansoni infection, we have studied the sensitivity, specificity and quantative features of an enzyme linked immunoassay (ELISA) using crude S. mansoni egg antigen preparation. Results of studies carried out in both London and St. Lucia indicate that the assay can give useful serodiagnostic information ranging from 82 to 99.5 percent sensitivity, depending on the level of infection intensity and method of blood collection and 100 percent specificity in St. Lucian/St. Vincent populations. The St. Lucia study also showed that the assay could be operated in a qualitative form in an endemic area (AU)
