Título: Serological studies on leptospirosis in livestock and chickens from Grenada
Fonte: Trans R Soc Trop Med Hyg;79(6):859-64, 1985.
Idioma: En.
Resumo: Sera from 1206 livestock animals and chickens in Grenada and Trinidad were tested for leptospiral antibodies by the microscopic agglutination test. 376 of the sera were positive (44 percent of those tested in Trinidad and 25 percent of those tested in Grenada). The positive sera were obtained from 25 percent of 324 cattle 35 percent of 130 pigs, 35 percent of 126 sheep, 25 percent of 44 goats, and 11 percent of 175 chickens in Grenada; and 92 percent of 26 cattle, 53 percent of 122 pigs, 76 percent of 86 horses, and 11 percent of 144 chickens in Trinidad. 8 sera from ducks and geese in Trinidad were tested and found to be negative. The serogroups most commonly found to react with sera of the Grenadian animals were Autumnalis, Icterohaemorrhagiae, Hebdomadis and the related serogroups Sejroe and Mini, and Pyrogenes; in the Trinidadian animals they were Icterohaemorrhagiae, Autumnalis, Hebdomadis and its related serogroups and Panama. Strains of serogroup Pomona do not appear to have become established as livestock pathogens on the islands (AU)

Título: Leptospires in the whistling frog (Eleutherodactylus johnstonei) on Barbados
Fonte: J Trop Med Hyg;93(2):140-5, Apr. 1990.
Idioma: En.
Resumo: Two groups of whistling frogs (Eleutherodactylus johnstonei) comprising 99 and 117 animals were examined for leptospiral infection. Group I animals were caught in 14 areas of Barbados, and group II animals in seven areas of suburban Bridgetown. Leptospires were isolated from the kidneys or body fluid of six frogs in Group I and the kidneys of 3 frogs in Group II. Two of the group I isolates died; the others were identified as bajan (a new serovar in the Australis serogroup) (6) and bim (Autumnalis) (1). The macerated body tissues and fluid of Group I frogs were put into phosphate buffered saline and examined by the microscopic agglutination test using 22 antigens. The results were all negative. For the Group II frogs the methodology was altered; blood was collected unto filter paper discs and allowed to dry out before being agitated in PBS and examined by the MAT. 15/117 (12.8 percent) animals were positive at o 1:50. The geometric mean titre was 179. Seventeen of the sera reacted predominantly to antigens in the Australis serogroup, and two to Pyrogens on its own. The serological results reflected the identity of the isolates. Serovars of Australis are not known to cause illness on Barbados, but bim is the commonest cause of severe leptospirosis on the island.

Título: Leptospiral infection in school-children from Trinidad and Barbados
Fonte: Epidemiol Infect;103(1):143-56, Aug. 1989.
Idioma: En.
Resumo: A serological survey for leptospiral agglutinins was undertaken between 1980 and 1983 in over 500 Barbadian and 500 Trinidadian school-children aged 7-14 years. The children were selected randomly from urban and rural schools, and examined three times at approximately annual intervals. A total of 12.5 percent of the Barbadian children and 9.5 percent of the Trinidadian children were seropositive at a titre of 50 using the microscopic agglutination test. On both islands, seroprevalence was higher in males than females, the difference being significant in rural schools. There was no evidence of a difference in prevalence between urban and rural schools, or between junior and secondary age-rangers. Analysis of the association of serology with socio-economic and behavioral factors showed a significant association in Trinidad with father's occuption, but most other variables on both islands showed only weak non-significant associations. Fourteen children in Trinidad and three in Barbados seroconverted. Seroconversion in Trinidad occurred at a rate of 1.6 percent per annum and was significantly associated with livestock contact and with absence of tapped water supply. In Trinidad, Autumnalis was the most commonly recorded serogroup, but this accounted for less than a quarter of seropositives. In Barbados, Panama accounted for over half the seropositives and was about four times more common than the next most common serogroup, Autmnalis. In Barbados, 39 persons aged 19 or less were hospitalized with leptospirosis between November 1979 and December 1986. Average annual incidence rates were 2.2, 4.9 and 13.3 per 100000 in the 5-9, 10-14 and 15-19 age-groups, respectivley. (AU)

Título: Leptospires in Rattus spp. on Barbados
Fonte: J Trop Med Hyg;94(2):102-3, Apr. 1991.
Idioma: En.
Resumo: Among 138 Rattus norvegicus and 98 R.rattus trapped on Barbados in 1964-65 and examined for evidence of leptosporal infection, sero-positivity prevalence rates were similar (34 and 39 percent, respectively), but isolation/dark field microscopy rates were higher in R. norvegicus (27 percent) than R. rattus (15 percent). R. norvegicus carried mainly serogroup Autumnalis. These two serogroups cause 90 percent of severe human leptospirosis on the island. (AU)

Título: Tropical acute rheumatic fever and associated streptococcal infections compared with concurrent acute glomerulonephritis
Fonte: J Pediatr;92(2):325-33, Feb. 1978.
Idioma: En.
Resumo: Ninety-three patients with acute rheumatic fever and 195 patients with acute glomerulonephritis were observed in Trinidad during an outbreak of scabies with a high incidence of secondary streptococcal infections. Clinical and laboratory manifestations of ARF were the same as those seen in temperate zones, except that antistreptolysin O titers were less markedly increased. The patients with ARF were similar to those with AGN in respect to sex, race, location of residence, and living conditions, but were older and had markedly fewer skin infections. Currently prevalent nephritogenic streptococcal strains never were isolated from patients with ARF even when M55 streptococci appeared and led to an epidemic of AGN.(AU)

Título: Leptospires in wildlife from Trinidad and Grenada
Fonte: J Wildl Dis;19(3):192-9, July 1983.
Idioma: En.
Resumo: Serum samples from 894 wild animals (representing 31 species) from Trinidad and Grenada were examined by the microscopic agglutination test for leptospiral antibodies; 198 were positive. These included 39 bats, 88 mongooses, six opossums, 10 peridomestic rodents, 15 forest rodents, 10 lizards and 30 toads. Thirteen pathogenic serogroups were involved. Thirty-nine Leptospira isolates were reported from mongooses, opssums, rodents and toads. (AU)
