This paper describes a translational application of the space-time distribution pattern of LF epidemics, 2008-2012 reported in Liberia, on which a predictive model was developed. We proposed a computationally feasible two-stage space-time permutation approach to estimate the time-trend parameters and conduct predictive inference on LF in Liberia.

Canine parvovirus (CPV) and feline panleukopenia virus (FPV), now included in the unique species Carnivore protoparvovirus 1 (CPPV1), have been circulating in dogs and cats for several decades and are considered the causes of clinically important diseases, especially in young animals. While genetic evidence of the circulation of parvoviruses in Egyptian domestic carnivores has been provided since 2016, to date, all available data are based on partial fragments of the VP2 gene. This study reports the molecular characterization of CPPV strains from Egypt based on the full VP2 gene. Overall, 196 blood samples were collected from dogs and cats presented at veterinary clinics for routine medical assessment in 2019 in Egypt. DNA extracts were screened and characterized by real-time PCR. Positive samples were amplified by conventional PCR and then were sequenced. Nucleotide and amino acid changes in the sequences were investigated and phylogeny was inferred. Carnivore protoparvovirus DNA was detected in 18 out of 96 dogs (18.8%) and 7 of 100 cats (7%). Phylogenetic analyses based on the full VP2 gene revealed that 9 sequenced strains clustered with different CPV clades (5 with 2c, 2 with 2a, 1 with 2b, and 1 with 2) and 1 strain with the FPV clade. All three CPV variants were detected in dog and cat populations with a predominance of CPV-2c strains (7 of 18, 38.9%) in dog samples, thus mirroring the circulation of this variant in African, European, and Asian countries. Deduced amino acid sequence alignment revealed the presence of the previously unreported unique mutations S542L, H543Q, Q549H, and N557T in the Egyptian CPV-2c strains.

Contamination of surgical sites often resulting from inadequate surgical site preparation and poor asepsis is a common cause of surgical site infection (SSI) and postoperative complications. Standard practice ensuring preoperative skin disinfection helps to prevent the incidence of SSI. The choice of antiseptic therefore poses a serious counterbalance for the surgeon. This study was carried out to determine whether skin asepsis immediately prior to surgical site incision will reduce skin microbial burden that may potentiate the incidence of SSI and to compare the clinical effectiveness of chlorhexidine gluconate B.P 0.3%W/V, Cetrimide B.P 3.05 W/V (CG + Cetrimide) against povidone iodine 10% (PI) in pre-surgical skin preparation and asepsis in dogs. A total of 15 dogs were used for the study. Both side of each dog was used for the study, right side for CG + Certrimide and left side for PI; (n = 30). Aseptic agents’ chlorhexidine gluconate 0.3% and Cetrimide 3.0% and povidine iodine 10% were used as pre surgical scrub solutions prior to surgery. Swab samples were evaluated before scrubbing, 0, 30, 60 and 90 min after scrubbing. Percent reductions of bacterial colony forming units were determined for all site scrub techniques. Mixed-design ANOVA results revealed significant difference (P < 0.05) within groups and no significant difference (P > 0.05) in the disinfectant effects between groups treated with CG + Cetrimide and povidone iodine respectively across the various time periods. Changes in the mean bacteria count were observed to be equivalent using CG + Cetrimide and povidone iodine. It was concluded that there was no significant difference between CG + Cetrimide and PI in preoperative surgical skin preparations.
