    Eimeria Meleagrimitis Tyzzer In Turkeys: the Life Cycle and Effects of Inoculum Size and Time On Severity of Infection and Intestinal Distribution (1980)

    Notes: Developmental stages of Eimeria meleagrimitis Tyzzer were found throughout the intestine and ceca of turkeys given inocula ranging from 104 to 7.5 × 105 sporulated oocysts/bird. Infection initially occurred in the duodenum and upper jejunum but later moved down the intestine and into the ceca. the speed with which the infection moved into these areas was roughly proportional to the inoculum size. Heaviest infections were in the ileum, neck of the cecum, and large intestine. the life cycle consisted of 5 asexual generations before gametogony, a 6th asexual generation developing simultaneously with gametogony. First- and 2nd-generations were located along the sides of villi in the upper intestine rather than in the crypts of Lieberkühn, as previously described in England for this species. Transitory first-generation stages that were abnormally large and usually degenerate were found in the neck of the cecum.

    Eimeria tenella: Vitamin Requirements for Development in Primary Cultures of Chicken Kidney Cells (1978)

    Notes: SYNOPSIS. Development of Eimeria tenella was studied in primary cultures of chicken kidney cells maintained in Medium 199 lacking each of the following: vitamin A. biotin, p-aminobenzoic acid, folic acid, nicotinamide, Ca pantothenate, pyridoxine, pyridoxal, riboflavin, thiamin, ascorbic acid, calciferol, α-tocopherol, and menadione. Data obtained concerning numbers of mature schizonts or total numbers of parasites or both indicated that all of the vitamins are needed for 1st- and 2nd-generation schizogony, and all except calciferol and folic acid are needed for gametogony.

    Development of Eimeria meleagrimitis Tyzzer from Sporozoites and Merozoites in Turkey Kidney Cell Cultures (1978)

    Notes: SYNOPSIS. Sporozoites and 1st-, 2nd-, and 3rd-generation merozoites of Eimeria meleagrimitis were inoculated into primary cultures of turkey kidney cells. In vitro-excysted sporozoites developed into mature macrogamonts in 8 days; in vivo-excysted sporozoites developed into 2nd- or 3rd-generation schizonts within 5 to 7 days. First-generation merozoites obtained from infected turkeys produced mature 2nd-generation schizonts within 24 h. Second-generation merozoites from turkeys produced mature macrogamonts and oocysts within 72 h, whereas 3rd-generation merozoites produced these stages within 48 h. The oocysts that developed from 3rd-generation merozoites sporulated at 25 C and were infective for turkeys.The timing of the early stages and the intervals between schizogonic generations in cultures were comparable with those in turkeys. Morphologic parameters, however, indicated that some differences existed between in vitro and in vivo development. Second- and 3rd-generation schizonts and gamonts that developed after inoculation of cultures with merozoites were similar to stages in turkeys. Oocysts, however, were significantly smaller (P 〈 0.05) in cultures. All stages that developed after inoculation of cultures with sporozoites were smaller (P 〈 0.05) than their in vivo counter parts.

    Notes: [Auszug] After being stored for 1 month, sporozoites of each species were quickly thawed in water at 43 C and inoculated into cell cultures (bovine embryonic kidney; cell line, twentieth passage) and into the caeca or duodenum of chicks and turkey poults, respectively. Control cultures and birds were ...
