Cytoplasmic Inclusion Body

A cytoplasmic inclusion body has been found in the epithelial cells of monkey kidney grown in tissue culture and infected with poliomyelitis virus. This inclusion is at first closely applied to the nucleus, and later develops into a clearly demarcated structure. The nucleus is pushed to the periphery of the cell and becomes pyknotic. Finally, the cytoplasm around the inclusion becomes vacuolated, and the cell breaks up at about the time virus first appears in the fluid part of the infected tissue cultures. Multiple small intranuclear eosinophilic inclusion bodies have also been found in some cells that contain cytoplasmic inclusions.

Low Concentrations

CMP-KDO synthetase (CKS) is an enzyme which plays a key role in the synthesis of LPS, an outer membrane component unique to gram negative bacteria. CKS activates KDO to CMP-KDO for incorporation into LPS. The enzyme is normally present in low concentrations (0.02% of total cell protein) which makes it difficult to perform large scale isolation and purification. Recently, the gene for CKS from E. coli was cloned and various recombinant DNA constructs overproducing CKS several thousandfold (unpublished data) were derived. Interestingly, no cytoplasmic inclusions of overproduced CKS were observed by EM (Fig. 1) which is in contrast to other reports of large proteinaceous inclusion bodies in various overproducing recombinant strains. The present immunocytochemical study was undertaken to localize CKS in these cells.Immune labeling conditions were first optimized using a previously described cell-free test system. Briefly, this involves soaking small blocks of polymerized bovine serum albumin in purified CKS antigen and subjecting them to various fixation, embedding and immunochemical conditions.

Scanning Electron

The surface architecture of the epidermis on the outer surface of the operculum (OE) and the epithelium on the inner surface of the operculum (EISO) of Garra lamta was examined by scanning electron microscopy. The surface appeared smooth on the OE and wavy on the EISO. A wavy epithelium is considered to facilitate an increase in its stretchability, during the expansion of the branchial chamber. The OE and the EISO were covered by a mosaic pavement of epithelial cells with characteristic patterns of microridges and microbridges. Interspersed between the epithelial cells were mucous goblet cell pores, which were not significantly different in number in the OE and the EISO. Nevertheless, their surface area in the EISO was significantly higher than in the OE. This could be an adaptation to secrete higher amounts of mucus on the EISO for keeping the branchial chamber lining clean, avoiding clogging, the increased slipperiness reducing friction from water flow and increased efficiency in protecting against microbial attachments. Rounded bulges on the OE and the EISO were associated with mucous goblet cells. The absence of the taste buds in the EISO, in contrast to the OE, suggests that their function in the branchial chamber may not be of much significance in this fish. Breeding tubercles on the OE are believed to facilitate better contact between the male and female during breeding.

Duodenal Epithelium

The fine structure of trophozoites, schizonts, merozoites and macrogamonts of Eimeria acervulina found in goblet cells of the duodenal epithelium of chicks is described and compared with the corresponding stages formed in other epithelial cells. Complete schizogony, with the formation of mature merozoites, occurred freely in goblet cells. Developing macrogamonts (but no microgamonts) were rarely found in goblet cells. The stages observed were confined to the cytoplasm of the host cell above the Golgi apparatus and were usually seen between the mucous granules. The stages seen appeared normal, and contained similar structures to corresponding stages developing in other cells. The finding of developing stages of E. acervulina in goblet cells provides further evidence that site specificity of Eimeria at the cellular level is not as strict as previously thought.

Thin sections of malva (Malva sp.) leaves collected in the field and showing mottle and vein-clearing symptoms were examined by electron microscopy. Cytoplasmic inclusions typical of potyvirus and consisting of pinwheels, laminated aggregates, and scrolls were readily observed. In addition, rhabdoviruslike particles were also seen in the perinuclear space of phloem parenchyma cells and within membranous sacs scattered throughout the cytoplasm of other vascular bundle cells. Occasionally rhabdoparticles could be found embedded in an amorphous electron-dense body located within the cell vacuole. The rhabdovirus particles, approximately 75 × 300 nm, were bound by a membrane with outer projections and had an inner core displaying cross striations. The cytoplasm of infected mesophyll cells had chloroplasts containing large amorphous inclusion bodies and had extensive membranous tubules that were frequently associated with the potyvirus inclusions. These ultrastructural aspects, the size of the particles, and the data on host range indicate that malva plants under study were doubly infected by viruses which were tentatively identified as malva vein-clearing virus and a previously undescribed rhabdovirus.

The small intestines of calves inoculated orally with the enteropathogenic strain of Escherichia coli 0101:K'B41′, K99 were examined by electron microscopy at 3, 6, 12, 16, 21, 36, 69, 70 and 72 hours after inoculation. The challenge organism adhered to the mucosa of the distal small intestine from six hours post-inoculation. Bacteria were separated from the microvillous brush border by a gap of 200 to 300 nm in which bacterial fimbriae and the microvillous glycocalyx were seen. Bacteria never were found in epithelial cells but were present in macrophages in the lamina propria from 12 hours. At three and six hours, cytopathic changes were not seen in the small intestine, but from 12 hours epithelial cells on affected villi had blunt and thick microvilli and contained cytoplasmic inclusions. Epithelial cells were seen frequently in the process of extrusion from the villi, either singly, in small groups, or as ribbons of cells. Intervillous bridges, characteristic of villous fusion, were seen frequently from 69 hours.

1. Cytoplasmic inclusions were found in the epithelial cells of the small intestine in a major proportion of suckling mice suffering from the spontaneous or experimentally produced diarrheal disease now prevalent in this laboratory. 2. They were not found in healthy stock mice of corresponding age. 3. Feeding of intestinal extract from healthy mice did not produce diarrhea or inclusions. 4. Feeding of boiled extract from diarrheal mice did not lead to the formation of cytoplasmic inclusions, when precautions were taken to prevent accidental infection. 5. The inclusions were regularly present only in the first few days of the disease. The inclusion-bearing cells desquamated. There was no inflammatory reaction. 6. Attention is called to the frequent presence of large numbers of Gram-positive coccoid bodies in the intestinal contents of suckling mice with diarrhea.

Rhesus monkeys (Macaca mulatta), given 3 × 108 to 5 × 1010Shigella flexneri 2a orally, developed signs of acute shigellosis within 24 hours. A diffuse acute colitis was well established at 48 hours. The inflammatory reaction was confined to the mucosa. The submucosa showed only edema. The shigellae were found predominantly in the columnar cells of the surface epithelium, less frequently in those of the crypt, and least frequently in the lamina propria. Shigella bacilli invaded the columnar cells from the intestinal lumen. The bacilli multiplied within epithelial cells and spread laterally to adjacent epithelial cells and penetrated the lamina propria. The bacterial invasion affected epithelial cells unevenly and resulted in the disappearance of goblet cells and pyknotic shrinkage of the surface epithelial cells. Epithelial cells had abnormal and accelerated exfoliation which resulted in multifocal epithelial defects. There was a distinct correlation between the quantity of bacilli present in tissues and the intensity of the inflammatory response. The small intestines were spared.

Pathologic and immunohistochemical changes caused by group I of the fowl adenovirus (FAV) serotype-1 99ZH strain, isolated from broiler chickens exhibiting gizzard erosion, were investigated in commercial broiler chickens. One hundred twenty-two chickens were inoculated with the strain by both oral and ocular routes at 1, 3, or 5 weeks of age and euthanatized for necropsy within 4–18 days of inoculation. Focal gizzard erosions were observed in the inoculated chickens of each age group. A histologically degenerative koilin layer, necrotic mucosa, intranuclear inclusion bodies in the glandular epithelial cells, inflammatory cell infiltrations in the lamina propria, submucosa, and a muscle layer were seen in the gizzards. Immunohistochemical staining showed evidence of FAV antigens in the intranuclear inclusion bodies. These findings were recognized regardless of their maternal antibody levels for FAV serotype-1. Gizzard lesions appeared later in the lower-dose-inoculated chickens than in the higher-dose–inoculated chickens. Numerous CD3-positive cells and IgY-positive plasma cells were seen in the gizzard lesions. In 5-week-old chickens the heterophil infiltrations in the lesions were milder than in younger chickens. Intranuclear inclusion bodies also were observed in the epithelial cells of the ileum or cecal tonsils of some chickens. Thus, this study shows that FAV-99ZH causes adenoviral gizzard erosion in broiler chickens without hepatic or pancreatic lesions and that cell infiltration is more severe than in dietary gizzard erosions.

Objectives The objective of this study was to examine the density and distribution of goblet cells (GCs) in the feline conjunctiva and to investigate a potential effect of age and sex on GC density (GCD). Methods Thirty-nine eyes of 21 cats euthanased for reasons unrelated to this study were used. Fixed upper and lower eyelid and bulbar conjunctiva were divided into nasal and temporal regions. The third eyelid was excised and investigated separately. Samples were embedded in paraffin wax; sections were stained with periodic acid–Schiff reaction and analysed with light microscopy. To determine the topographic distribution of GCs, each region was subdivided into the marginal, palpebral and bulbar zone. In each zone 200 epithelial cells, including GCs, were counted. Goblet cell index was defined as a percentage of the epithelial cells. Results The palpebral zone of both eyelids contained significantly ( P <0.001) more GCs (27.5–32.0%) than the marginal or bulbar areas. The highest GCD was found in the nasal palpebral zone of the upper eyelid (32.0%). Marginal and bulbar sites contained fewer numbers of GCs (2.6–10.0%). The lowest GCD was detected in the nasal bulbar zone of the lower eyelid (2.6%). Overall the nasal region contained significantly ( P = 0.036) more GCs than the temporal region, but there was no significant difference in GCD between the upper and lower eyelids. Correlation analysis did not show any effect of age or sex on GC counts. Conclusions and relevance GCD in the palpebral zones and on the anterior surface of the third eyelid was highest; the lowest density was found in the bulbar zones of the lower eyelid and in the marginal zones of both eyelids. Overall, higher GCD was found in the cat than in other species. Age and sex have no effect on GCD.
