Canine distemper is a highly contagious disease with high incidence and lethality in the canine population. The objective of this study was to evaluate the efficacy of antiviral action with ribavirin (RBV), interferon-alpha (IFNa), and combinations of RBV and IFN a against canine distemper virus (CDV). Vero cells inoculated with CDV were treated with RBV, IFNa, and combinations of these drugs. The efficacy to inhibit viral replication was evaluated by adding the compounds at different times to determine which step of the viral replicative process was affected. Both drugs were effective against CDV in vitro. The IFNa was the most active compound, with an average IC50 (50% inhibitory concentration) value lower than the IC50 of the RBV. Ribavirin (RBV) was more selective than IFN a, however, and neither drug showed extracellular antiviral activity. The combination of RBV and IFN a exhibited antiviral activity for the intra- and extracellular stages of the replicative cycle of CDV, although the intracellular viral inhibition was higher. Both RBV and IFN a showed high antiviral efficacy against CDV, and furthermore, RBV 1 IFNa combinations have shown greater interference range in viral infectivity. These compounds could potentially be used to treat clinical disease associated with CDV infection.

Objective—To evaluate the effect of ambient temperature on viral replication and serum antibody titers following administration of an intranasal modified-live infectious bovine rhinotracheitis (IBR)-parainfluenza-3 (PI3) virus vaccine to beef calves housed in high– (> 32°C) and moderate– (21°C) ambient temperature environments. Animals—28 calves (mean weight, 206.8 kg). Procedures—Calves were randomly allocated to 4 treatment groups (housed outdoors during high ambient temperature with [HAT; n = 10] or without [HAC; 4] vaccination or housed indoors in a moderate ambient temperature with [MAT; 10] or without [MAC; 4] vaccination). Rectal and nasal mucosal temperatures were recorded every 2 hours from 8 AM to 8 PM on days 0 (vaccination) and 1. Nasal swab specimens were obtained on days 0 through 7 for virus isolation. Serum samples were collected on days 0, 7, 14, and 28 for determination of antibody titers. Results—Mean rectal temperature did not differ among the treatment groups. Mean nasal temperature for the HAT group was significantly higher than that for the MAT group at 6, 24, 30, 32, and 38 hours after vaccination. Viable IBR virus was isolated from all vaccinated calves on days 1 through 6. Two weeks after vaccination, vaccinated calves had anti-IBR antibody titers that were significantly greater than those for unvaccinated calves. Mean anti-IBR antibody titers did not differ significantly between the HAT and MAT groups. Conclusions and Clinical Relevance—Results indicated that, following vaccination with an intranasal modified-live IBR-PI3 virus vaccine, IBR viral replication and serum antibody titers did not differ significantly between calves housed in high– and moderate–ambient temperature environments.

Over the past 20 years, major progress has been made in our understanding of critical aspects of rabies epidemiology and control. This paper presents results of recent research, highlighting methodological advances that have been applied to burden of disease studies, rabies epidemiological modelling and rabies surveillance. These results contribute new insights and understanding with regard to the epidemiology of rabies and help to counteract misperceptions that currently hamper rabies control efforts in Africa. The conclusion of these analyses is that the elimination of canine rabies in Africa is feasible, even in wildlife-rich areas, through mass vaccination of domestic dogs and without the need for indiscriminate culling to reduce dog population density. Furthermore, the research provides valuable practical insights that support the operational planning and design of dog vaccination campaigns and rabies surveillance measures.

Bacteriological examination was performed on 60 local healthy fish of fresh water include 30 Carp fish (Cyprinus carpio) and 30 Cat fish (Silurus glanis) with different weights from local retail fish markets at Mosul city, during the period from sept. 2011 - Sept. 2012. Swabs from skin and parts of muscles, livers, intestines incubated in brain heart infusion broth for 24 hours at 37 ̊ C (aerobic culture), a loopful from incubated broth were streaked on blood agar, milk agar, mannitol salt agar incubated plates at 37 ̊ C for 24 h, selected colonies were submitted to gram staining, morphological characteristics biochemical tests for Staphylococcus. The percentage of Staphylococcus isolation was 100% for all examined samples of fish. A total of 130 isolates from both two species of examined fish (62) isolates from Cyprinus carpio and (68) isolates from Silurus glanis , a five species of Staphylococcus S. saprophyticus (29% , 29.4%), S. epidermidis (21% , 22%), S. hyicus (17.75% , 17.7%), S. aureus (17.75% , 19.1), S. intermedius (14.5% , 11.8%) , were identified with different numbers and percentages for Cyprinus carpio and Silurus glanis respectively . While percentages of Staphylococcus isolates from skins (35.5% , 36.8%), muscles (17.7% , 20.6%), livers (25.8% , 25%), intestines (21% , 17.60%) from both species Cyprinus carpio and Silurus glanis respectively. Antibiotic sensitivity test result for six antibiotics (Ampicillin, Gentamicin, Chloramphenicol, Polymaxin, CO-Trimaxazol , Ciprofloxacin) were variable most species of Staphylococcus isolates were resistant to Ampicillin but sensitive to Ciprofloxacin.

A surveillance study was conducted to determine the rates of mixing beef illegally with other selected animal species meats of inferior quality in Kerbala Governorate. Over an 8-month period ( September 2012 to May 2013), a total of 120 samples of meat products viz., 40 local minced meats, 40 local beef burger and 40 imported beef burger were purchased from Kerbala city and analyzed by Agar Gel Immuno-Diffusion test ( AGID) for detecting substitution of undesirable meat species. Meat extracts from camel, chicken and donkey were prepared. Rabbits were injected with meat extracts for preparation of hyper-immune sera, whereas, blood was collected to get the specific anti-sera. Positive result was recorded when precipitation line observed between the antibody and the corresponding meat extract. The incidence of adulteration was detected in 6 (5%) samples with camel meat and 23 ( 19.16%) samples with chicken meat, while none of the samples was found adulterated with donkey meat .Camel meat found in 4 (10%), 2 ( 5%) and 0 ( 0%) of local minced meat, local beef burger and imported beef burger respectively. However, chicken meat detected in 8 (20%), 10 (25%) and 5 ( 12.5%) of local minced meat, local beef burger and imported beef burger respectively. It was concluded that substitution of meat products, in which inferior quality meat is mixed into beef, has been existed in Kerbala G
