Ahmed Ali Hussein | Jihad A. Ahmed
This study was conducted in the veterinary medical college, university of Basra.The objective of this study was to know the histopathological effect of propofol asanesthetic agent on dogs organs (central nervous system, heart, liver) and effect ofpropofol on liver enzymes, Propofol administration for 90 days by intravenous (intocephalic vein) into 8 adult dogs which divided into two equal groups. The controlgroup was injected with 0.9% normal saline (1ml/kg), while the propofol group wasinjected with (10mg /kg) body weight of dog per day. The measured parameters AST,ALT showed a significant difference in groups between zero time and after 90 days.Also the histopathological result of brain, heart and liver showed significant changesas atrophic neurons, nerve fibers vacuolation and gliosis and histopathological resultof heart section showed white areas of degenerate myocardial muscle cells withpresence of adipose tissue and congested blood vessels, white areas of degeneratemyocyte as infiltration of adipose tissue at pericardial region (periphery) and areas ofdestruction of myocardial muscle cells while the histopathological changes ofhepatocyte showed septal fibrosis, bile duct proliferation, fine defuse vacuolation ofhepatocyte and hypertrophic of bile duct. The uses of propofol for the long term maycause serious Histopathological injuries in many organs particularly the brain andliver that may due to its direct interaction in these structural units.

Bluetongue (BT) is a vector-borne disease of ruminants caused by Bluetongue virus (BTV). Twenty-nine different serotypes of BTV are currently reported throughout the world. The main objective of this study is the development of a subunit vaccine model that could potentially be adapted to provide broad spectrum protection against multiple BTV serotypes, which the conventional vaccines fail to address. To this end, three different BTV proteins (conserved region of viral protein [VP]2, VP5 and NS1) were expressed and purified in an Escherichia coli expression system. The immunogenicity of these proteins was tested in murine models using the MontanideTM ISA 201 VG adjuvant. BALB/c mice were immunised thrice (with individual proteins and a mixture of three proteins) at two-week intervals and were monitored until Day 40 post-infection/vaccination. Protein-specific antibodies directed against the recombinant proteins were detected by indirect enzyme-linked immunosorbent assay. Neutralising antibody (Nab) titres and cross-neutralisation against a range of BTV serotypes (BTV-1, -2, -4, -5, -9, -10, -12, -16, -21, -23 and -24) were determined by serum neutralisation test. The recombinant proteins elicited higher Nab titres compared with the inactivated vaccine group, except for BTV-1, where the inactivated vaccine group elicited higher Nab titres. Additive effect of the three proteins was not observed as the Nab titres generated with a combination of conserved VP2, VP5 and NS1 was similar to those of the individual protein groups. Whilst BTV-12 could only be neutralised by serum raised against the inactivated vaccine group, BTV-5 and -24 could not be neutralised by any of the groups tested. Our cumulative data suggest that the conserved regions of VP2 (cVP2), VP5 and NS1 could play an important part in the novel vaccine design against multiple BTV serotypes. Importantly, given that VP2 was already known to elicit a serotype-specific immune response against BT, we report, for the first time, that the conserved region of VP2 has the ability to induce cross-protective immune response.

In this study, positive blood and organ samples were obtained from different mixed herds of sheep and cattle against ovine herpesvirus 2 (OvHV-2) infection. Target-positive DNA was sequenced and compared with worldwide distributed OvHV-2 sequences. Tegument gene (422 base pairs) and glycoprotein B (gB) gene (2800 base pairs) amplicons of OvHV-2 genome were used for understanding of epidemiology of malignant catarrhal fever (MCF) infection in Turkey. The results of nucleotide sequencing of polymerase chain reaction (PCR) products indicated presence of sheep-associated form for MCF infection in Turkey. Although the obtained sequences were genetically different from each other, it was found that genetic variations were limited.

Trichinella zimbabwensis naturally infects a variety of reptilian and wild mammalian hosts in South Africa. Attempts have been made to experimentally infect piranha fish with T. zimbabwensis and T. papuae without success. Tigerfish (Hydrocynus vittatus) and African sharp tooth catfish (Clarias gariepinus) are accomplished predators cohabiting with Nile crocodiles (Crocodylus niloticus) and Nile monitor lizards (Varanus niloticus) in southern Africa and are natural hosts of T. zimbabwensis. To assess the infectivity of T. zimbabwensis to these two hosts, 24 African sharp tooth catfish (mean live weight 581.75 ± 249.71 g) randomly divided into 5 groups were experimentally infected with 1.0 ± 0.34 T. zimbabwensis larvae per gram (lpg) of fish. Forty-one tigerfish (mean live weight 298.6 ± 99.3 g) were randomly divided for three separate trials. An additional 7 tigerfish were assessed for the presence of natural infection as controls. Results showed no adult worms or larvae of T. zimbabwensis in the gastrointestinal tract and body cavities of catfish sacrificed at day 1, 2 and 7 post-infection (p.i.). Two tigerfish from one experimental group yielded 0.1 lpg and 0.02 lpg of muscle tissue at day 26 p.i. and 28 p.i., respectively. No adult worms or larvae were detected in the fish from the remaining groups sacrificed at day 7, 21, 28, 33 and 35 p.i. and from the control group. Results from this study suggest that tigerfish could sustain T. zimbabwensis under specific yet unknown circumstances.

Examination of 528 (450 males and 78 females) dromedary camels slaughtered at Cairo abattoir revealed that a total of (93) 17.6 % were infected with hydatidosis. Post mortem examination revealed that infection was restricted only in the lungs and the liver of infected camels. Among the 93 hydatidosis infected camels, lungs were the most frequently infected 88 (94.623%) compared with liver 5 (5.376%). ELISA test using partially crude antigen and purified antigen is important for the early diagnosis of cystic echinococcosis as most cases in the early stages of infection are asymptomatic. Sensitivity of ELISA using the crude antigen was 82.758% while sensitivity of the partially purified antigen was 79.310 %. On the other hand specificity of the crude antigen was estimated as 62.5 % and specificity of partially purified antigen as 75.0 %.

M. Nayel | A. El-Sify | S. Akram | M. Allaam | E. Abdeen | H. Hassan
In this study multiplex PCR was used for typing of Clostridium perfringens isolates from soil, clinically healthy and diseased sheep. Clostridium perfringens was isolated from 41 out of 100 soil samples, 12 out of 100 clinically healthy sheep and 118 out of 200 sheep with enterotoxaemia signs. Genotyping of 41 isolates from soil indicated that 29 (70.73%) were type A, 3 (7.31%) were type B and 9 (21.95%) were type D. Of 12 isolates from clinically healthy sheep 6 (50%) were type A and 6 (50%) were type D. Of 118 isolates from diseased sheep 42 (35.59%) were type A, 22 (18.64%) were type B and 54 (45.76%) were type D. This result indicates that Clostridium perfringens type A, B and D are the main types causing enterotoxaemia in sheep in Egypt and Clostridium perfringens type A must be included in any vaccine programme to ensure optimum protection.

The study aimed to investigate the presence of peste des petits ruminants (PPR) in pneumonic lung tissues from clinically apparently healthy sheep and goats and further demonstrating its prevalence in Gezira state, central Sudan. During March 2019, 99 pneumonic lung samples were collected from apparently healthy sheep (80) and goats (19) from Al-Hasaheisa slaughterhouse located in Al-Hasaheisa locality, Gezira state. Using the haemagglutination (HA) test for the detection of peste des petits ruminants virus (PPRV) antigen, an overall antigenic prevalence of 86.9% was demonstrated in sheep and goats lung tissue homogenate. Of note, the prevalence of PPRV is higher in goats (100%) compared to sheep (83.7%). In this study, the reported increasing prevalence of PPR in central Sudan might be because of insufficient vaccination of animals. The findings of the present study indicated the widespread of PPR amongst sheep and goats in Al-Hasaheisa, Gezira state. Detection of PPRV antigen in the pneumonic lung samples is an indication of exposure of these animals to PPRV or presence of PPR viral infection and demonstrates the role of PPR as the cause of pneumonia in small ruminants. In fact, the circulation of the virus in clinically apparently healthy animals poses a threat for other in-contact susceptible animals and could play a significant role in the spread of the disease.
