OBJECTIVE To evaluate the diagnostic yield of dental radiography (Rad method) and cone-beam CT (CBCT) methods for the identification of 31 predefined dental disorders in brachycephalic dogs. ANIMALS 19 client-owned brachycephalic dogs admitted for evaluation and treatment of dental disease. PROCEDURES 31 predefined dental disorders were evaluated separately and scored by use of dental radiography and 3 CBCT software modules (serial CBCT slices and custom cross sections, tridimensional rendering, and reconstructed panoramic views). A qualitative scoring system was used. Dental disorders were grouped into 10 categories for statistical analysis. Point of reference for presence or absence of a dental disorder was determined as the method that could be used to clearly identify the disorder as being present. Accuracy, sensitivity, specificity, and positive and negative predictive values were calculated with the McNemar χ2 test of marginal homogeneity of paired data. RESULTS When all 3 CBCT methods were used in combination, the diagnostic yield of CBCT was significantly higher than that of dental radiography for 4 of 10 categories (abnormal eruption, abnormally shaped roots, periodontitis, and tooth resorption) and higher, although not significantly so, for all categories, except for 1 (loss of tooth integrity). CONCLUSIONS AND CLINICAL RELEVANCE CBCT provided more detailed information than did dental radiography. Therefore, CBCT would be better suited for use in diagnosing dental disorders in brachycephalic dogs.

Foot-and-mouth disease (FMD) is one of the major trans-boundary animal diseases in East Africa causing economic loss to farmers and other stakeholders in the livestock industry. Foot-and-mouth disease occurs widely in both Uganda and Tanzania with annual outbreaks recorded. With the recent introduction of the Progressive Control Pathway for FMD control (PCP-FMD) in eastern Africa, knowledge of the spatial and temporal distribution of FMD at the border area between Uganda and Tanzania is helpful in framing engagement with the initial stages of the PCP. Retrospective data collected between 2011 and 2016 from four districts located along the border areas of Uganda and Tanzania, recorded 23 and 59 FMD outbreaks, respectively, for the entire study period. Analysis showed that 46% of the 82 recorded outbreaks occurred in 20% of sub-counties and wards immediately neighbouring the Uganda–Tanzania border and 69.5% of the outbreaks occurred during the dry months. While the serotypes of the FMD virus responsible for most outbreaks reported in this region were not known, previous research reported South African Territory (SAT) 1, SAT 2 and O to be the serotypes in circulation. The results from this study provide evidence of the endemic status of FMD on the Uganda–Tanzania border and emphasise that the border area should be given due consideration during FMD control drives and that cross-border coordination should be prioritised. With the limited data on circulating serotypes in this area, there is a need for more vigilance on FMD case detection, laboratory diagnostic confirmation and provision of more complete documentation of outbreaks. This work further recommends more studies on cross-border livestock movement coupled with phylogenetics in order to understand the spread of the FMD in the border area.

This study was carried out on twelve Holstein dairy cows. Five cows were clinically healthy and considered as control; three cows with left displacement of abomasum (LDA) and four cows with right displacement of abomasum (LDA). Diagnosis of DA based on clinical examinations and confirmed by ultrasonography. The Hb, PCV%, total leucocytic count, neutrophils and abomasal fluid pH were significantly increased (P<0.05) in RDA compared to control. Serum biochemical analysis showed significant reductions of sodium, potassium, chloride and calcium in LDA and RDA and significant increases (P < 0.05) in glucose and total proteins in RDA compared to the control. Moreover, there were significant increases (P<0.001) in ALT, AST, LDH, CPK, urea and creatinine in LDA and RDA compared to control. In conclusion, abomasal displacement produces alterations in the clinical, hematological and biochemical picture compared to control healthy cow and these alterations may vary according to the type of displacement

The present study was conducted to study the immunomodulatory effect of combined of extract of propionobacterium and E.coli lipopolysaccharide (inmunair 17.5) to enhance the immune response of rabbits to rabbit haemorrhagic disease virus (RHDV) vaccine. Forty New Zealand rabbits aged 2 months with average weight 1.5-2 kgs were divided into 4 equal groups. Group (1) was vaccinated with RHDV vaccine and the immunomodulator, group (2) was only vaccinated with RHDV vaccine, group (3) was received the immunomodulator only and the last group was kept as non-vaccinated, no-treated control. The results revealed that three days oral administration of the immunomodulator under test at time of RHDV vaccination had an improving effect on both humoral and cell mediated immune response of rabbits to RHDV vaccine. Results obtained by challenge test come in harmony with serological test

Bovine tuberculosis; caused by Mycobacterium bovis,is a zoonotic diseasecausing approximately 6% of total human deaths. Its economic losses are not only a reduction of 10-20% in milk production and weight, but also infertility and condemnation of meat.Many serological tests are applied for detection of tuberculosis. ELISA test has the highest sensitivity and specificity than the other serological tests for the diagnosis of tuberculosis. Several forms of new technology were brought into the diagnostic approach to mycobacterial infection. The aim of this work was to detect bovine tuberculosis by application of different serological tests. Tuberculin skin test was applied on 2650 cattle, only 63(2.4%) were positive. Forty eight (76.2%) of the slaughtered positive animals showed visible lesions (VL) while the other 15 (23.8%) had non-visible lesions (NVL). The bacteriological examination of the 63 samples revealed isolation ofM. bovis from 47 processed samples (74.6%). The results of the immunoassay test have detected 27 out of the tuberculin positive cattle, while the ELISA has detected 34 out of the positive reactor cattle. It was concluded that immunoassay and ELISA tests act as complementary tests for tuberculin skin test especially in anergic cattle.

A total of (120) sample of ready to eat (RTE) meat;(20) each of cooked luncheon, frankfurter, hot dog, pasterma, shawrma and smoked luncheon were collected from different shops and grocery stores in Beni-Suef City. To be examined for their microbial load for aerobic plate count (APC), most probable number (MPN) of coliforms, fecal coliforms and E.coli as well as Staphylococcus aureus and enterococci were enumerated. Additionally E.coli, salmonella and Listeria were isolated and identified biochemically. Aerobic plate count (APC) had the highest mean value in shawerma (1×107 ± 5×106CFU/g), shawerma also showed the highest most probable number (MPN) of coliforms and fecal coliforms (11 and 6 CFU/g) mean while pasterma was the highest contaminated with Staphylococcus aureus (3×104 CFU/g) and the highest count of enterococci was detected in hot dog (3×105 CFU/g). On the other hand each of E.coli, Salmonella and Listeria species were failed to be detected in any of the examined samples. The public health significance as well as the recommendations to produce safe and high quality ready to eat (RTE) meat products were mentioned.

A total of 1317 samples were collected; 1164 serum samples, 122 milk samples, 24 lymph nodes and 7 aborted foeti from buffaloes in 10 Governorates from farms and villages in Upper Egypt. The serological tests used for the diagnosis of brucellosis on blood sera were the Rose Bengal plate (RBT) , Buffered acidified plate antigentest (BABAT), EDTA modifiedstandard tube agglutination test (MSAT), Revanol test (RT). On the other hand, the milk ring test (MRT) was performed on buffalo-cow's milk. Suspected colonies were stained with Gram, s stain and Modified ZeilNeelson stain. The isolated Brucella organisms on antibiotic free Brucella agar medium were subjected to the following tests for biochemical identification tests as CO2requirement, H2S production, Urease activity, growth in the presence of dyes,The indirect solid phase ELISA technique was carried out according to serum and milk samples.Agar gel immune diffusion test (AGID) and PCR applied on isolated Brucella strains. The results of the serological tests wereRose Bengal test 34.7%, BAPA (37%), Revanol test (28.2%),modified SAT (23.7%), indirect ELISAwere (32.3%) and AGPT (33.8%)in this study.Brucellaorganisms from lymph nodes of slaughtered buffaloes by culturing method showed that 3 (13.64%) isolates(2) of B. melitensisbiovar 3 and (1)B. abortusbiovar1. The isolated strain from aborted foeti was one isolate (14.29%) typed as B.melitensisbiovar 3. isolated only from Beni-Suef.By milk ring test (MRT) milk samples were 10 (8.20%) of B. melitensis biotype 3. A multiplex was format that will allow the rapid identification of Brucella spp., B. abortus, and B.melitensis in a single test within 2 to 3 h. B. melitensis was identified at 731bp and B. abortus identified at 498bp. Finally, we made measures of the control program for eradication of brucellosis in buffaloes by a reasonable system of compensation, Veterinarians for field work and state laboratories capable of serological techniques.Also, information technology solutions and further logistic means as animal identification techniques are in any governorates in Egypt.

The present study aimed to ellucidate the prenatal developmental stages of the submandibular salivary gland of the New-Zealand rabbits. To conduct that, twenty New-Zealand rabbit fetuses ranged from 11 to 30 days-old were used. The head region of fetuses and gland specimens were fixed, processed and stained with histological stains to be examined by light microscope. The submandibular primordia was firstly seen at the 12th day of the prenatal life as bilateral invaginated epithelial buds from the linguo-gingival groove. At 15 days-old , such buds continued deep down growth forming cord-like structure ended by compact bulges that forming the future primitive acini. At 17 days, such cords were branched off forming the future primary ducts. Canalization of the ducts appeared at 18 days. At 22 days, the primitive capsule initiated around the gland and the lobulation was recognized. At 25 days, the capsule became well developed, the duct system was completed and the parenchyma occupied by serous adenomeres surrounded by myoepithelial cells. At the full term, the submandibular gland became fully developed and became typically compound tubulo-acinar nature, the parenchyma showed seromucoidadenomeres. Strong positive PAS reaction was noticed in the striated ducts, while the cytoplasm of the acinar cells reacted weakly

Presently neither the specification of rumen cannula for small ruminants is reported nor is it commercially available in Egyptian market. Therefore, fabrication of ruminal cannula for sheep and surgical procedure for its implantation are described in this paper. The device was adapted to allow sampling of entire ruminal contents via cannulas with different diameters, which tightly sealed within ruminal fistula to ensure cleaner, achieve easier nursing of operated animals, and maintain more normal ruminal environment. The ruminal cannula was applied into the sheep by one-stage operation. It has been successfully used in 11 ram (3-5 year-old) for 16 months without problems and caused no complications.

The aims of this study were twofold: to assess the welfare of two hybrids of laying hens in conventional cages and to investigate the effects of tier’s level on the integument condition and fearfulness. Two commercial hybrids, white Lohmann Selected Leghorn (LSL) and brown Lohmann Traditional (LT) at about 18 weeks of age were used in the current study and were housed at three hens / cage. No birds were beak-trimmed. External appearance of the body (scoring of plumage condition and skin injuries at body parts and comb), heterophil-lymphocyte (H-L) ratios and duration of tonic immobility (TI) were used as indicators of well-being. LSL birds showed better plumage condition and low H-L ratios than LT birds while no significant difference was recorded in TI test between the two hybrids. Hens housed in the top tier showed worse feather condition and more wounds than birds in middle and bottom tiers whereas for fear levels, no significant difference was revealed for hens from different tiers of cages. These results suggest that the welfare of LSL birds was relatively good compared to LT. Therefore, conventional cages can be used by the hens to a large extent if birds are properly selected to be specifically adapted to cages.
