S. E. El-Sadek | A. A. M. El-Gendy | M.A. Tohamy | M. A. Abd El-Aa
The Anti-inflammatory, antipyretic and analgesic effect of Achillea millefolium and Salix were investigated in rats and mice. The extracts of Achillea millefolium exerted significant antiinflammatory, antipyretic and analgesic effects. Also potentiated the sleeping time of thiopental sodium in mice. The doses used were 10.375 and 20.75 (watery extract) and 9.5 and 19 mg/100 gm b.wt. (ethanolic extract). Salix produced the same effects at doses of 0.0825 and 0.165 (watery extract) and 0.0850 and 0.170 mg/100 gm b.wt. (ethanolic extract). The extracts of both plants have an anti-inflammatory, antipyretic and analgesic effect

2007
Hanan, A. Fahmy | Omayma, M. El Desawy
A total number of 80 nasal swabs collected from apparently normal cattle slaughtered in Basateen abattoir were screened for the presence of infectious bovine rhinotracheitis virus. Among 80 examined samples, 4 samples found positive after the 3rd passage on MDBK cell line with appearance of the specific cytopathic effect (grape like clusters). The isolated virus titers were 103.9, 104.2, 105, 105.6 TCID50 / 0.1 ml. The four positive isolates were identified by agar gel precipitation test (AGPT), virus neutralization test (VNT) and gave the intracytoplasmic granules by indirect fluorescent antibody technique (IFAT). Electrophoretic profile of IBR in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was described and visualized by Coomassie blue stain. The mobilities of electrophoretic bands were determined with molecular weight marker at approximate range from 206.39 to 22.14 kDa.

2007
M. M. Amer | Wafaa A. Abd El-Ghany
This study was carried out to investigate the possible bacterial causes affecting theproductivity of the breeder hens. The hens under test were positive for Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) and negative for Salmonella gallinarum-pullorum (S. g-p) as tested by serum agglutination test. Ovaries with lesions were bacteriologically and serologically proven to have 12 bacterial isolates including three un-typed E. coli, one O11, and one O78; three Staphylococcus aureus; one S.g-p; two Proteus and one Pseudomonas aeruginosa (P. aeruginosa)isolates. The antibiogram of the two identified E. coli strains, S. g-p as well as P. aeruginosa showed variable sensitivity. The tested organisms were very sensitive to colistin and enrofloxacin. The selected E. coli, S.g-p and P. aeruginosa strains proved to be pathogenic to 3-day-old chicks, with induction of clinical signs, mortalities, post mortem lesions and adverse effect on the body weight gain. On the other hand, E. coli O78 was more pathogenic than O 11. The use of the abovementioned drugs for controlling of those infections in chicks was effective as indicated by the results of the in vitro test. It is important to carry out bacteriological examination to the breeder flocks in order to investigate the bacterial affections with estimation of changes in their sensitivity to the used antibiotics.

2007
V. Mbao | D. Berkvens | P. Dorny | P. Van Den Bossche | T. Marcotty
Stabilates of Theileria parva sporozoites are mostly delivered in liquid nitrogen tanks to the East Coast fever immunization points. Using an in vitro titration model, we assessed the loss of infectivity of several stabilates when they are stored in ice baths for up to 24 h. Comparisons, with respect to rates of loss of infectivity, were made between T. parva stocks (Chitongo and Katete), cryoprotectants (sucrose and glycerol) and method of assessment (in vivo and in vitro techniques). Chitongo and Katete stabilates showed similar loss dynamics. The losses were 1-4 % (depending on parasite stock) and 3 % per hour of storage for glycerol and sucrose stabilates respectively, and the loss rates were not significantly different. The results suggest that Chitongo stabilates and sucrose cryoprotected suspensions can be delivered on ice as is done for Katete. A graphical relationship of in vitro effective dose at 50 % infectivity (ED50) and in vivo protection rate was made. The relationship showed a 35 % loss of protection for a relatively low corresponding increase of ED50 from 0.006 to 0.007 tick equivalent.

2007
K. Junker | J. Boomker
Published and personal records have been compiled into a reference list of the helminth parasites of guineafowls. Where data on other avian hosts was available these have been included for completeness' sake and to give an indication of host range. The parasite list for the Helmeted guineafowls, Numida meleagris, includes five species of acanthocephalans, all belonging to a single genus, three trematodes belonging to three different genera, 34 cestodes representing 15 genera, and 35 nematodes belonging to 17 genera. The list for the Crested guineafowls, Guttera edouardi, contains a single acanthocephalan together with 10 cestode species belonging to seven genera, and three nematode species belonging to three different genera. Records for two cestode species from genera and two nematode species belonging to a single genus have been found for the guineafowl genus Acryllium. Of the 70 helminths listed for N. meleagris, 29 have been recorded from domestic chickens.

The sensitivity of LAMP, PCR and microscopy to detect Theileria spp. and Trypanosoma congolense in field-derived bovine blood samples from Tanzania was evaluated and compared. No parasites were detected by microscopy. Furthermore, no bovine Theileria spp. were detected by LAMP and PCR from all the 24 samples collected from Arusha. Four and one out of 24 samples were positive for Theileria congolense infection by LAMP and PCR respectively while, 18 and nine out of 40 samples from Dar es Salaam were positive by LAMP and PCR for Theileria spp. Infection, respectively. Although all samples from Dar es Salaam were negative for Trypanosoma congolense infections by PCR, 12 out of 40 samples were LAMP positive. Whilst PCR is an established gene amplification method for the detection of Theileria and trypanosome parasites, this study introduces LAMP as an alternative molecular diagnostic tool that could be used in large-scale epidemiological surveys.

The importance of milk for the growth and health of a newborn offspring is well known. Milk contains immunoglobulin G (Ig G), Ig A, lactoperoxidase, lactoferin, cytokines, and growth factors. Osteopontin, one of the multifunctional proteins, is secreted by macrophages, T cell, and epithelial cells. Although osteopontin production in bovine milk have been documented, the precise expression levels in bovine milk have not been clarified. The aim of this study was to observe the expression of osteopontin, in bovine milk during the lactation period or bovine mammary glands.

Ahn, D.C. (Kangwon National University, Chuncheon, Republic of Korea) | Kim, I.S. (Chonbuk National University, Jeonju, Republic of Korea), E-mail: iskim@chonbuk.ac.kr
The left main descending artery (LMDA) of left coronary artery (LCA) in rats runs around the left side of conus arteriosus after arising from the aortic sinus and descends to the apex of heart with branching several branches into the wall of left ventricle (LV). The ligation site of LMDA for myocardial infarction (MI) is the 2~4 mm from LCA origin, between the pulmonary trunk and left auricle. The characteristics that rat heart has no interventricular groove on the surface and its coronary arteries run intramyocardially with branching several branches give the difficulty in surgery for MI which resulted in expected size.

Lee, J.U. (Seoul National University, Seoul, Republic of Korea) | Kim, S.H. (Seoul National University, Seoul, Republic of Korea) | Park, T.W. (Wonkwang University, Iksan, Republic of Korea) | Kim, O.J. (Wonkwang University, Iksan, Republic of Korea), E-mail: kimoj@wonkwang.ac.kr
Helicobacter pylori (H. pylori) is an important bacterial pathogen that causes chronic gastritis and is associated with gastroduodenal ulcer disease, adenocarcinoma of the distal stomach, and gastric lymphoma in humans. The differences of host susceptibility of H. pylori infection associated with host age have not been well-defined in human. To evaluate the difference in host susceptibility to infection in relation to age of acquisition of H. pylori infection, we designed an experiment involving inoculation of H. pylori ATCC 43504 at different ages of Mongolian gerbils.
