Food preparation in colonial America. A Bicentennial study.

Both regional and national influences have pervaded America's culinary arts from colonial times until the present. In the South, for instance, indigenous foods, such as sweet potatoes--as well as an abundance of fruits and fowl--were commonly served. In the North, maple sirup was a New England product, as was codfish. Throughout the colonies, corn was easily grown and became a staple. Immigrants from the Old World brought their recipes to meld or adapt to conditions they met here. Recounted also is the unfolding of an American cuisine, especially in the southern colonies as it evolved from European food preparation practices. Cooking was done in great fireplaces, with equipment designed to fit. Meat was generally boiled or stewed in pots hung in the fireplace, although it might be slow-roasted on a hand-turned spit. Hot breads, the hallmark of southern cooking, date from colonial days. In the Noth, the Dutch farmer's wife developed real skill in using flour from home-grown wheat and rye, creating pancakes, waffles, doughnuts, crullers, and so on. After the first hard winter, food in New England became more plentiful. Boston brown bread was made from corn, wheat, or rye and probably sweetened with maple sirup. Imports of coffee, tea, and spices from the Orient and fruit from the tropics were later added to the cuisine. Colonial Americans understood well the art of food preparation and appreciated the taste of well prepared, well seasoned dishes.

The Aymara of Western Bolivia. II. Maxillofacial and dental arch variation.

Maxillofacial and dental arch dimensions of the Bolivian Aymara population are age and sex dependent. Interpopulational comparisons reveal these dimensions to differ from those seen in Aleuts, Australian aborigines, and Swedes, but to be similar to those of the indigenous Taiwanese. Finally, these dimensions are not the same in Aymara of unmixed ancestry, and Mestizos residing in the same villages.

Mitochondrial DNA diversity in Ecuadorian populations: Recurrence of variant 16136 within haplogroup B2.

The identification of lineage-defining variants, frequently found in the coding region of mitochondrial DNA (mtDNA), is essential for refining haplogroup classification. Most mtDNA studies in South American populations have focused on the control region (CR), which has provided important insights into population structure and maternal lineage origins, although information needed for more robust phylogenetic resolution has been neglected. This study investigates the maternal genetic structure of Ecuadorian populations by combining CR and whole mitogenome analyses. Sequences from the mtDNA CR were obtained from 461 individuals (253 Mestizos and 208 Native Americans), while complete mitogenomes were sequenced for 127 individuals to improve phylogenetic resolution by identifying lineage-defining variants present in coding region. Most mtDNA haplogroups in the two population groups analyzed were of Native American origin (A2, B2, B4, C1, D1, D4), with significant differences in the distribution of specific lineages between them. Among Mestizos, African haplogroups (all within the L branches) and Eurasian haplogroups (H, K, R, U) were detected at low frequencies, whereas no African lineages were observed among Native Americans. The results obtained highlighted a heterogeneity within Ecuadorian populations that must be considered when developing mtDNA haplotype databases for forensic purposes. Whole mitogenome sequences enabled the identification of variants that refined haplogroup classifications, provided a more accurate reconstruction of the maternal genetic diversity, and improve the discrimination between Native American and Asian maternal lineages within haplogroup B4b.

Non-specific ileojejunitis in Arequipa, Peru.

Non-specific ileojejunitis, characterised by mild to moderate structural changes in the intestinal mucosa and often associated with asymptomatic malabsorption, is known to occur in the tropics and in countries with hot climates. This acquired condition is probably related to environmental factors, and some consider it to be a subclinical form of tropical sprue. Changes in the intestinal mucosa typical of non-specific ileojejunitis were found in 10 indigenous Indians as well as 5 people of Latin stock living in the Southern Peruvian sierra, where tropical sprue has not as yet been demonstrated and which has a temperate climate.

Primary hyperparathyroidism in Black South Africans.

Despite the presence of stimuli to parathyroid activity, such as low dietary intake of calcium and low serum calcium levels, primary hyperparathyroidism is extremely uncommon in the indigenous population of Africa south of the Sahara. We report the occurrence of primary hyperparathyroidism in 3 black patients, all of whom presented with gross bone disease, high serum calcium levels, short histories of hyperparathyroidism and large parathyroid tumours. The clinical manifestations of hyperparathyroidism in these patients are probably due to the rapid rate of tumour growth and high level of hormone production.

Hallucinogenic plant use and related indigenous belief systems in the Ecuadorian Amazon.

This review article focuses on the on-going use of plant hallucinogens, especially various Banisteriopsis species, among contemporary aboriginal populations of Ecuador. It surveys the evidence of prehistoric ayahuasca use by interpretations of Ecuadorian archaeological remains, and surveys in detail the use and belief systems connected to major plant hallucinogenic use among the Jibaro Indians and other tribal groups. A secondary theme includes coastal and Inter-Adnean aboriginal drug use. The article stresses the interrelatedness of aboriginal belief systems, folk medicine and world view linked to plant hallucinogenic ingestion.

Concurrent replication of a papovavirus and a C-type virus in the CCL 33 porcine cell line.

A papovavirus, CCL 33 PV, isolated from a porcine cell line, CCL 33 (GT), was characterized. Based on a comparison of four isoenzyme systems, CCL 33 (GT) and CCL 33 (ATCC), obtained directly from the American Type Culture Collection, appeared to be the same. In addition to the previously characterized C-type virus of CCL 33 cultures, CCL 33 (GT) produced CCL 33 PV in high quantity, but CCL 33 (ATCC) produces a papovalike virus, presumably the same as CCL 33 PV, in barely detectable amounts. Serological results showed that CCL 33 PV is apparently identical to a papovavirus (SPV) isolated by Newman and Smith after inoculation of CCL 33 with concentrated porcine trypsin. These studies extend the characterization of this papovavirus, demonstrating that CCL 33 PV is weakly hemagglutinating after neuraminidase treatment, has a high affinity for a component of fetal bovine serum and is highly infectious in appropriate porcine cell systems rather than very defective as reported previously. Moreover, it was concluded from the data that CCL 33 PV is probably indigenous to the CCL 33 porcine cell line.

[Seroepidemiologic study of human cysticerosis in the predominantly indigenous rural Indian population of the State of Chiapas].

The overall proportion of sera with antibodies against cyticercus antigens in 3226 serum samples collected among the Indian rural population in the proximity of San Cristóbal de Las Casas, Chiapas, México is 0.49. The proportion of positive sera varied from 0.4 to 7.6% inversely with the number of inhabitants in the community. The global proportion of positive sera in Chiapas being considerably lower than that expected from the autopsy frequency of brain cysticercosis in México City (1.4-3.6%), it is perhaps indicative of different epidemiologic dynamics in rural and urban areas.

[Pre-Columbian indigenous psychopharmacology].

A careful review has been carried out on texts concerning Mexican medicine plants, especially on texts obtained directly from the XVI century Indian reports. The plants utilized for psychiatric purposes have been separated from the huge group of 1 500 medicine plants used by the prehispanic Indians, and have been found about 150 plants which have been classified in the modern way of antipsychotic, antidepressant, minor tranquilizer, hallucinogens, sedatives, hypnotics, brain tonics, stimulants and anticonvulsants. The intention in making this research is to awake the interest of the people in the experimenting field; as experiments have been effected only on hallucinogen up to now, and if these have proved to possess the effects caused to the Indians, supposedly large part of the other plants have the effects according to the indications they have mentioned.

Rodent control programmes in areas affected by Bolivian haemorrhagic fever.

Bolivian haemorrhagic fever (BHF) caused by Machupo virus is acquired by contact with the excretions and secretions of Calomys callosus, an indigenous cricetine rodent which is preadapted to peridomestic habitats. It competes successfully with Mus musculus, but not with Rattus rattus. A successful disease control programme has functioned in Beni Department since 1964. It is based on trapping surveys and the detection of splenomegaly in Calomys rodents as an index of chronic virus infection. Mass trapping and poisoning are used initially, and regular trapping is employed to control Calomys populations in towns where disease has occurred. More than 1000 cases of BHF were recorded from 1960-1964, but less than 200 in the past 10 years. The cost of this programme is approximately $30 000 annually.

El hospital invisible. A study of Curanderismo.

This report presents the results of interviews with 16 Mexican-American folk healers (curanderos and curanderas) in San Antonio, Tex. Curanderismo was found to be alive and well in San Antonio, though its practitioners tend to be older and its future unclear. Several salient characteristics of the practitioners were clarified such as the process of becoming a healer, referral practices, types of disorders treated, and treatment of the traditional folk illnesses. We take a basically conservative position on whether curanderos can ever be incorporated into the health care delivery system. However, this study confirms that the practitioners and their clients simultaneously utilize the folk medical system and the scientific medical system.

Caffeine intake and potential effect on health of a segment of northern Canadian indigenous people.

There are strong indications that the caffeine intake of Canadian Northern Indigenous People is very substantial. Tea is the main contributor. Preliminary calculations show that daily ingestion of caffeine among these groups is much higher than ingestion levels known to have adverse medical and behavioral effects. Of particular concern is the interaction of caffeine and carbohydrate metabolism, already known to be under stress due to increases in sugar and carbohydrate intake. Symptoms characteristic of unduly high intake of caffeine are also found to a large extent in hypoglycemia, mercury intoxication, and various nutritional deficiencies. There is a need for a substantial research effort to further delineate the caffeine problem and to develop alternate beverages containing reduced amounts of caffeine.

Espanto: a dialogue with the gods.

Espanto or susto has been analysed from various points of view in the last fifteen years. From a survey covering 109 case analyses collected in Nicolas Ruiz (Chiapas, Mexico), we reached the conclusion that this folk illness cannot be conceived of as a syndrome in the medical sense. A semiological analysis showed that espanto can be better described as an indigenous theory whose function is to relate illness events to other levels of reality. According to indigenous belief, the Holy Earth and the chtonian spirits of the underworld play an important role in the origin of the illness. This origin is associated with an opening of the earth as is illustrated in the earthquakes or the volcanic eruptions forming the prototype of a fright experience leading to espanto; or, it is attributed to agents who inhabit locations where the earth presents a fissure (river, ravine, cave). It is through these holes that the Holy Earth exerts her power. Concomitantly, the body of the victim is believed to open itself to the influences of the bad winds of espanto. Trembling is another aspect of the phenomenon which is observed at numerous levels: first, during the fright experience; second, when the victim falls ill (chills jumping in bed); and third, when the curandera takes the pulse of the patient to see if the blood is afraid. These multiple analogies lead to the assumption that there is a meaning shared by these separate manifestations.

The Kren-Akorore: a recently contacted indigenous tribe.

Primitive groups of people, living in complete isolation, are rarely encountered these days. In fact, the process of 'approximation', or contact, depends upon decisions made on both sides--that representing the civilized world and that representing the group called by us 'primitive'. The isolated group, however, can never perceive the tremendous risks its members will inevitably encounter one the barrier of isolation, by which they are protected, has been broken. Civilized man has the means of persuasion and attraction at his disposal and also knows the risks involved. It must therefore be his responsibility to protect and preserve the group right from the initial contact. In spite of the medical resources available, primitive man has paid heavily in human lives through contact with the civilized world. This raises two equally important question: (a) have medical resources been thoroughly applied to protect these groups? And (b) are the existing medical resources sufficient to ensure the survival of primitive man once his state of isolation has been broken? Without any definite answers to these questions, we are limited to describing our experiences with the Kren-Akorore Indians, recently contacted in Central Brazil. We also present data on the biological characteristics of these Indians, collected two years after the first contact.

Incidence of invasive group A streptococcal infections and comparison of emm types from invasive infections, pharyngitis, and throat carriage in American Indian communities in the Southwest United States.

BACKGROUND: American Indian/Alaska Native (AI/AN) communities in the US have high rates of group A streptococcal (GAS) infections. We determined the incidence of invasive infections in AI communities in the Southwest and compared emm types from invasive infections, pharyngitis, and throat carriage. METHODS: Activities conducted in the White Mountain Apache Tribal lands (WMA) and Navajo Nation (NN) included active, laboratory-based surveillance for invasive GAS infections (WMA: 2019─2024; NN: 2023─2024; all ages); surveillance for GAS pharyngitis (2023-2024; children 0─17 years); and culture for GAS from oropharyngeal carriage samples (2019 and 2022─2023; children 0─14 years). Emm types were determined by whole-genome sequencing. Annual incidence rates were calculated using Poisson regression. RESULTS: In WMA, age-standardized rates of invasive infections ranged from 80-270/100,000 persons between 2019-2024. Predominant emm types varied (n=74 isolates): 91 (59%) and 49 (32%) in 2019-2020, and 43 (40%) and 53 (30%) in 2023. In NN, rates were 40-60/100,000 persons in 2023-2024; common emm types (n=51) were 53 (28%), 101 (18%), and 12 (16%). In WMA and NN, emm types 1, 12, and 53 predominated in pharyngitis (n=190), and 1, 12, and 91 in throat carriage (n=119). CONCLUSIONS: Rates of invasive GAS infections in these communities were 3-35 times higher than the national US average (12.2/100,000 in 2024). Emm types varied over time with limited overlap in strains from throat carriage or pharyngitis isolates and those from invasive infections. Findings support continuing GAS surveillance and engaging AI/AN communities throughout vaccine development and evaluation.
