Entamoeba: Species, Classification and Biology outlines the current knowledge about the global epidemiology, clinical manifestations, pathogenesis, available diagnostic tools and management of pathogenic Entamoeba species in humans. The authors provide an overview of the various species belonging to the genus Entamoeba, including Entamoeba histolytica, Entamoeba dispar, Entamoeba gingivalis, Entamoeba coli, Entamoeba moshkovskii, Entamoeba invadens, Entamoeba polecki, Entamoeba hartmanni, Entamoeba suis, Entamoeba nuttalli, Entamoeba bangladeshi, Entamoeba struthionis and Entamoeba muris. The general pathogenic factors of Entamoeba histolytica are described, particularly focusing on how these factors participate in establishing infection. Additionally, an review of studies centered on the morphological, biochemical and genetic changes during programmed cell death of Entamoeba histolytica is provided. Current knowledge on the identification, characterisation, structure, and function of the enzymes of serine biosynthesis is also summarized.

The story of men who become rich is not uncommon. But it is rare to find the story of a man who rose from the very lowest rank in society, a member of a despised caste known as the chattel slave, to a position among the greatest, as a renowned missionary and lecturer. BORN THREE TIMES is a truly inspiring narrative of human potential and capacity. Thomas Johnson depicts his life under slavery and his life as a free man. The great change in condition, from prisoner to world traveller, from an insignificant "nobody" to celebrated evangelist and speaker - all this seems to be fiction, but it is absolutely true. He describes his slow steps in education. Tasks which other people conquer in childhood, such as learning the alphabet, he must deal with as an adult. Scenes of life which are taken for granted by the free-born, are challenging and unnerving to those who had lived in bondage. Further, Johnson reveals the many complex feelings he had about people and places. In something that is rare in books of this kind, he even discloses the secret opinions he and other slaves held of different cultures. England was considered by them to be the greatest nation in the world, because Queen Victoria had done so much to liberate the oppressed. Although he acknowledged that as a black man his racial homeland was in Africa, he appears to have felt surprisingly limited resonance with the culture he encountered during his missionary work there. Johnson made what was at the time a very audacious decision, to move his family overseas to Europe. He felt his real place was in England, a land with which he had absolutely no racial, ethnic or cultural affiliations. He makes clear his reason: the widespreadprejudice in America, North and South, that existed against former slaves made his life intolerable. However, he noted that this prejudice was not as evident against those blacks visiting from other nations-an interesting comment on the peculiar nature of racism. Johnson believed that there would be less racism amongst people who had never tolerated slavery in their own country. One indeed detects in his writing a genuine warmth towards the people of his new home, an intangible feeling he cannot explain.

A poignant collection of 150 photographs, "Camera Man's Journey" takes us to a place at once familiar and foreign. Set in the South early in the twentieth century, these photographs bridge a distance not only of time but also of contrasting attitudes and customs.

The images show African Americans in or around Columbia, Beaufort, and Hilton Head, South Carolina. Some photographs were taken in surroundings where blacks might associate with whites--out of necessity and according to strict custom. Most of the images, however, are set in "colored sections" or other remote areas of town and country where blacks were obliged to fashion lives apart. Under segregation and disenfranchisement, men, women, and children are portrayed in ordinary occupations and pursuits: a peddler selling his wares, a woman tying a toddler's shoes, a barber and his young apprentice taking a break outside their shop.

Julian Dimock, whose works appeared often in major travel and nature magazines, took the photographs in 1904-5. So many photographers of the era tended to romanticize or politicize their African American subjects; Dimock was different. Signs of want and inequity are plain to see in these images, but Dimock portrays his subjects as they really were in all of their dignity, strength, and beauty.
