| pig production in the solomon islands. i. village pig production. | in 181 villages in the solomon islands the pig: human ratio was 1:5-8 and the annual per capita pork consumption was 4-2 kg. some communities did not keep pigs or eat pig meat. sows weaned an average of 5-5 piglets per year and mean liveweight at 12 months of age was 28-4 kg. most pigs were kept on the ground but some were housed in pens over the sea and very few lived in their owner's houses. pigs were important in the social life of the people but proportionally fewer pigs were raised than in ... | 1977 | 906090 |
| pig production in the solomon islands. ii. diseases and parasites. | a study of diseases and parasites of pigs in the solomon islands during 1967 to 1969 indicated that infectious diseases were of little consequence. four arthropod parrasite species were found: one tick, one louse and two tabanids. the tick (amblyomma cyprium cyprium) was extremely rare. fifteen species of helminth parasites were recorded and of these stephanurus dentatus was the most prevalent. all species were identified except a filariid, of which only the microfilariae were seen. | 1977 | 910298 |
| pig production in the solomon islands. iii. the influence of breed, diet and housing on reproduction and growth. | in the solomon islands pigs grow slowly and sows have small litters. an experiment using 124 pigs in 16 litters from eight sows compared the effect of village breed, village diet and village husbandry which encouraged infection of pigs with stephanurus dentatus, with the effect of european breed, commercial rations and a system of management which ensured freedom from s. dentatus infection on the productivity of pigs. it was shown that the village diet was markedly inferior to the commercial rat ... | 1977 | 595139 |
| changes in vector species composition and current vector biology and behaviour will favour malaria elimination in santa isabel province, solomon islands. | in 2009, santa isabel province in the solomon islands embarked on a malaria elimination programme. however, very little is known in the province about the anopheline fauna, which species are vectors, their bionomics and how they may respond to intensified intervention measures. the purpose of this study was to provide baseline data on the malaria vectors and to ascertain the possibility of successfully eliminating malaria using the existing conventional vector control measures, such as indoor re ... | 2011 | 21961990 |
| cross-neutralizing antibodies to pandemic 2009 h1n1 and recent seasonal h1n1 influenza a strains influenced by a mutation in hemagglutinin subunit 2. | pandemic 2009 h1n1 influenza a virus (2009 h1n1) differs from h1n1 strains that circulated in the past 50 years, but resembles the a/new jersey/1976 h1n1 strain used in the 1976 swine influenza vaccine. we investigated whether sera from persons immunized with the 1976 swine influenza or recent seasonal influenza vaccines, or both, neutralize 2009 h1n1. using retroviral pseudovirions bearing hemagglutinins on their surface (ha-pseudotypes), we found that 77% of the sera collected in 1976 after im ... | 2011 | 21695241 |
| identification of residues outside of the receptor binding domain that influence the infectivity and tropism of porcine endogenous retrovirus. | identification of determinants of human tropism of porcine endogenous retrovirus (perv) is critical to understanding the risk of transmission of perv to recipients of porcine xenotransplantation products. previously, we showed that a chimeric envelope cdna encoding the 360 n-terminal residues of the human-tropic perv envelope class a (perv-a) su and the 130 c-terminal residues of the pig-tropic perv-c su and all of tm (perv-a/c) showed a 100-fold decrease in infectivity titer on human cells (m. ... | 2008 | 18508891 |
| functional hierarchy of two l domains in porcine endogenous retrovirus (perv) that influence release and infectivity. | the porcine endogenous retrovirus (perv) gag protein contains two late (l) domain motifs, pppy and p(f/s)ap. using viral release assays we demonstrate that pppy is the dominant l domain involved in perv release. pfap represents a novel retroviral l domain variant and is defined by abnormal viral assembly phenotypes visualized by electron microscopy and attenuation of early perv release as measured by viral genomes. psap is functionally dominant over pfap in early perv release. psap virions are 3 ... | 2008 | 18355887 |
| mice transgenic for a human porcine endogenous retrovirus receptor are susceptible to productive viral infection. | porcine endogenous retrovirus (perv) is considered one of the major risks in xenotransplantation. no valid animal model has been established to evaluate the risks associated with perv transmission to human patients by pig tissue xenotransplantation or to study the potential pathogenesis associated with perv infection. in previous work we isolated two genes encoding functional human perv receptors and proved that introduction of these into mouse fibroblasts allowed the normally nonpermissive mous ... | 2006 | 16537582 |
| influence of development factors on nutritional patterns in the solomon islands. | looks at the general changes brought about by development, and how the nutritional habits of the solomon island communities have been affected by development. the development aspirations of third world countries include the introduction of cash crops for foreign exchange; moving away from subsistence-type economy and self-reliance in feeding one's family to dependence on outside sources; employment of more people at salaried jobs, small industries and factories; and modernization. many governm ... | 1981 | 12265890 |
| comparative effects of permethrin-impregnated bednets and ddt house spraying on survival rates and oviposition interval of anopheles farauti no. 1 (diptera:culicidae) in solomon islands. | human-biting, cdc light trap and pig-baited collections were used to monitor changes in the abundance and parity rate of anopheles farauti no. 1 mosquitoes in three solomon islands villages for 30 consecutive nights. houses in one of the villages were sprayed with ddt, another village was unsprayed but its inhabitants used permethrin-treated bednets and the third village was left completely untreated. mosquitoes collected each day were dissected to determine follicular maturation and parity. in ... | 1995 | 7495366 |
| epidemic polyarthritis (ross river) virus infection in the cook islands. | an epidemic of ross river virus infection occurred in the cook islands early in 1980 and affected the majority of the inhabitants of rarotonga, the most populated island in the group. this represents the easternmost extension of the virus which, until 1979, was believed limited to australia, new guinea, and the solomon islands. the clinical manifestations of ross river disease, predominantly polyarthritis, did not differ significantly from those observed previously in australia. however, unlike ... | 1981 | 7325286 |
| additional description of a new species of tunga (siphonaptera) from ecuador. | a new species of chigoe flea belonging to the genus tunga jarocki, 1838 (siphonaptera, pulicidae, tunginae), tunga trimamillata, was recently described by pampiglione et al. (2002). a better description and more details of the epidemiology of the flea are now presented. it is a species found in goats, pigs and cattle in santa isabel in andean ecuador. this new species differs from its most similar congener, tunga penetrans (l., 1758), by several features, the most important of which are a) the p ... | 2003 | 12669344 |
