| food antibodies in milk from guatemalan women. | this study investigates the presence of antibodies against food products in milk samples from 30 guatemalan women of 3 different socioeconomic status: 10 rural poor, 10 urban poor, and 10 urban privileged. the 3 groups had varied dietary habits. both the rural and urban poor mothers do not consume cow's milk. black beans are consumed more often by the urban groups while soy bean products are consumed by both rural and urban poor regularly. milk samples were collected from the mothers. the ... | 1981 | 7196944 |
| entomological studies at an enzootic venezuelan equine encephalitis virus focus in guatemala, 1977-1980. | the ecology of several potential mosquito vectors of venezuelan equine encephalitis (vee) alphavirus was studied in an enzootic focus of that virus on the pacific coast of guatemala over a four-year period. four species-culex taeniopus, mansonia titillans, culex nigripalpus and aedes taeniorhynchus-were most prevalent during the wet season when transmission normally occurs. however, only cx. taeniopus yielded vee virus. the bloodfeeding patterns of these species revealed that ae. taeniorhynchus ... | 1986 | 2873752 |

| [modified-habitat use by tropical forest-dependent birds in the caribbean region of guatemala]. | modified-habitat use by tropical forest-dependent birds in the caribbean region of guatemala. as natural areas are reduced into isolated remnants, the importance of secondary habitats for species conservation will increase. consequently, the conservation value of human-modified or created secondary habitats must be determined. in this study, we evaluated the conservation potential of three habitats associated to cattle ranching (riparian forest, live fence, and pasture) for tropical forest birds ... | 2009 | 19637718 |

| ticks and tick-borne disease in guatemalan cattle and horses. | blood samples and ticks were collected from 48 cattle and 74 horses from seven sites in the peten region of guatemala. data on body condition, mucous membrane capillary refill time and tick infestation levels were recorded for each animal in the study. horses had significantly higher levels of tick infestation than cattle, as well as poorer body condition scores. seroprevalence of babesia spp. was 95.8% for b. bovis in cattle, 89.6% for b. bigemina in cattle, and 92.7% for b. equi in horses. ser ... | 2005 | 15936147 |

| a neglected mayan galactagogue - ixbut (euphorbia lancifolia). | a herbal tea, made of leaves of ixbut (euphorbia lancifolia schlecht.), has been used for several centuries by postpartum mayan women in guatemala to stimulate and increase the flow of mother's milk. ixbut, when mixed with cattle fodder, is reputed to have increased milk yields in cows. to date, the active principle of ixbut has never been isolated. however, this medicinal herb, a natural galactagogue of central american origin, would appear to be worthy of further chemical and pharmacological s ... | 1982 | 7033669 |
| the immune response of the mammary gland and its significance for the neonate. | the immune response of the mammary gland is dominated by local production of secretory iga antibodies (siga). these milk antibodies, amounting to about 0.5-1 g/day throughout lactation, are directed against food proteins and microorganisms often present in the intestine. this is presumably explained by the enteromammaric link: after antigenic exposure in the peyer's patches of lymphoid cells they home to various exocrine glands, including the mammary gland. similarly, lymphoid cells from the bro ... | 1984 | 6391286 |

| epidemiology of babesiosis and anaplasmosis in south and central america. | babesiosis (babesia bovis and babesia bigemina) and anaplasmosis (anaplasma marginale) affect native cattle from uruguay and northern argentina to guatemala. the distribution of babesia follows the dissemination of the tick vector. seroepidemiological studies showed that enzootic instability exist in herds in several areas of the region. however, clinical cases occurred less frequently than expected. the babesial tick infection rate is related to the vector abundance which in turn is regulated b ... | 1995 | 7597777 |
