A study was conducted from November 2010 to February 2011 to determine the prevalence and estimate the economic loss of bovine fasciolosis in OdaBultum district based on the carpological examination and abattoir survey. Out of total of 384 fecal samples taken from cattle and examined, 182 (47.39%) were found positive for fasciolosis ,prevalence on months basis revealed higher prevalence rate (48.78%) in January and the lower (43.47%) was observed in November. No statistically significant variation (p>0.05) was observed in the monthly occurrence of the disease. Among the three localities (Godahora, Odaroba and Odabiyyo) from which fecal samples were taken higher infection rate (48.75%) was recorded in Odabiyyo while the lowest (46.27%) was noted at Odaroba. Statistical analysis of the result revealed no significant differences in prevalence among the three localities. Prevalence among the age groups showed 48.32% and 46.75% in young and adult age groups, respectively. No statistically significant difference in prevalence was seen between the two age group (p>0.05). Prevalence on the basis of sexes indicated 50% in male and 45.53 in females but the difference was not statistically significant (p>0.05). A four month post mortem examination of 197 cattle slaughtered at baddessa town municipal abattoir revealed the overall prevalence of 47.68%. Statistical analysis showed that there was no significant variation in monthly prevalence during the study period (p>0.05). Analysis of economic losses associated with liver condemnation in the study abattoir indicated a total of 13,498 ETB has been estimated to be lost each year in the abattoir as a result of fasciolosis. The current study has indicated that disease is of considerable economic significance therefore, calls for implementation of an appropriate control measures.

Important Disease

Peste des petits ruminant (PPR) is an economically important disease of small ruminants with a rapidly expanding geographical distribution. There are fragmented reports to the occurrence and distribution of the disease in Ethiopia. A total of 700 serum samples were collected from goats and sheep to detect the presence of antibody against PPR virus using Competitive Enzyme-Linked Immunosorbent Assay (C-ELISA). An overall PPR seropositivity was reported to be 48.43% in the area. There is no statistically significant difference in the seroprevalence of the disease between sheep and goats (50.85% and 46.68%), respectively. However, there was statistically significant variation (P<0.05) in the seroprevalence of the disease in young (33.9%) and adult (55.8%) age categories. The seroprevalence in male and female was 42.07% and 50.09%, respectively, where the variation was statistically not significant (P>0.05). High seroprevalence of Peste des petites ruminants in the study area indicated the virus circulation and endemicity of the disease. The disease causes substantial economic losses by affecting the livelihood of the farmers. Therefore, control measures should be put in place to minimize the loss associated with the disease.

Background: Handwriting is a uniquely human trait which progresses and evolves during lifetime and declines with age. The aim of the present paper is to assess variation in handwriting features with age among female writers of select population groups of Delhi, India (for roman script). Method: A total of 405 handwritten samples were obtained from female (n=405) writers in the age range of 14-60 years. Writers were stratified into three age groups (≤ 18 years, 19-38 years and ≥39 years) in accordance to population group. Macro- and micro-features of handwriting were extracted from the scanned handwritten samples. These features were subjected to statistical analysis in the objective driven research. Result: The mean difference among age groups for pen pressure, height of handwriting and handwriting connectivity was statistically significant (p < 0.001). Significant difference was also observed among age groups for all micro-features of handwriting selected in the present study, namely, nature of ‘i’ – dot (p < 0.001), nature of lower loop of ‘g’ (p < 0.01); nature of‘d’- stem (p < 0.01), nature of ‘m’-hump (p < 0.05) and ‘r’- shape (p < 0.001). Conclusion: The present study showed that there was a significant variation in both macro- and micro- features of handwriting with respect to age of the writer. Pen pressure, height of handwriting and handwriting connectivity were prominent macro-features that addressed age related variation in handwriting. In addition, significant variation was observed among age groups for all micro-features of handwriting selected in the present study. The present study has immense forensic significance as it can assist to analyze age of the writer on the basis of handwriting characteristics.

All around the world, intestinal helminths constitute one of the most prevalent life-long occurring infections and re-infections affecting all horse age groups. A range of parasite species among strongyles, ascarids, and tapeworms is known to have the potential to cause colic in horses. However, there is a lack of current scientific evidence on the actual relevance of helminth infection levels in the context of colic in horses kept during prevailing epidemiological conditions. Thus, a prospective case-control study on the occurrence of intestinal helminths in a total of 620 mainly adult equine clinic patients was conducted to investigate the association between colic and helminth infection. For each horse, a range of copromicroscopic, serological, and clinical data was obtained, in addition to a questionnaire on relevant anamnestic data, including previous anthelmintic treatment and husbandry. Using a FLOTAC-based copromicroscopic diagnosis, the highest infection rates were seen for strongyles (41.8%), followed by Anoplocephala perfoliata and Parascaris spp. (both 0.8%), with no significant difference between the two study groups. Employing a real-time PCR a 1.1% S. vulgaris DNA prevalence was found. Considerably higher seroprevalences were observed using S. vulgaris and A. perfoliata ELISAs, with 32.3% and 10.7%, respectively. It was noteworthy that no association concerning either serologic status was encountered with colic status. The shedding of strongyle eggs was associated with a 1.8-times increased risk of S. vulgaris seropositivity. Recent anthelmintic treatment was associated with the onset of colic, as animals who had received an anthelmintic during the previous week had a 2.4-times higher risk of signs of colic compared to those who had been treated at least eight weeks prior. Another noteworthy observation was that ponies were significantly less often affected by colic than warmbloods. The high S. vulgaris and considerable A. perfoliata seroprevalences encountered in this investigation should prompt veterinarians, farm managers, and horse owners to maintain consequent and effective worm control measures.

Enteric viral diseases of swine are one of the most frequent disorders causing huge economic losses in pork production. After the reappearance of an emerging enteropathogen, porcine epidemic diarrhoea virus (PEDV) in Hungary in 2016, an extensive survey was initiated in an attempt to identify diarrhoea-related porcine viruses, including adeno-, astro-, boca-, calici-, circo-, corona-, kobu-, rota- and Torque teno viruses. A total of 384 faecal samples collected during a twoyear period from diarrhoeic and asymptomatic pigs of various ages in 17 farms were screened by conventional and real-time PCR methods. Half of the samples contained at least one examined virus with the dominance of kobuvirus (55.1%) followed by bocaviruses (33.2%) and rotavirus groups A and C together (20.9%), while coronaviruses including PEDV were not found in this set of samples. Statistical analysis showed a highly significant difference (P < 0.0001) in the frequency of single infections compared to mixed ones with the exception of weaned pigs, in which group additionally most viruses were detected. The results of this study suggest that the complexity of this disease may vary with age, which makes the prevention of diarrhoea a challenge, especially in weaned pigs.

Abstract Background: Lungworms are parasitic nematode round worms that infest the lungs of ruminants. The infections have wide distribution in the world including Ethiopia. Epidemiological distribution of lung worm depends more on pasture contamination by carrier animals. Diagnosis is based on clinical signs, postmortem findings and laboratory testing (detecting lungworm larvae in faces). The aims of this study were to determine the current prevalence, identifying the species and assess the possible risk factors of lung worm infection in cattle and sheep at Gondar Elfora abattoir.Result: Out of 500 animals (240 cattle and 260 sheep) both coprological and postmortem examination were conducted. The overall occurrence of lungworm infection in both cattle and sheep were 3.75% and 7.31% respectively. The prevalence of lung worm in cattle and sheep in ante mortem inspection with respiratory problem was 8.00% and 19.51% respectively. Coprological prevalence of infection: in young and adult age groups of cattle was 7.04% and 2.37% and in sheep 6.8% and 7.9% respectively. With regard to body condition (poor, medium and good) having the prevalence of 13.64%, 3.3% and 0.00% in cattle and 16.2%, 5.35% and 7.33% in sheep respectively. It has significant difference with body condition score of cattle and sheep (p<0.05 The occurrence of identified lung worm in cattle was Dictyocaulus viviparous (3.75%); in sheep Dictyocaulus filaria (52.63%) higher than Muellerius capillaries (36.84%) followed by Protostrongylus rufescens(10.53%). Over all prevalence in cattle and sheep were 1.67% and 8.08% respectively. Finding with respect to young and adult age groups of cattle was 4.23%, 0.59%, and in sheep 7.48% and 8.85%. The identified lung worm species in sheep, mixed infection (42.85%) was higher than Dictyocaulus filarial (28.57%) followed by Muellerius capillaries (19.05%) and Protostrongylus rufescens (9.52%). Conclusions: Generally lungworm infection has a great effect on animal health and production. It needs emphasis to prevent and control to overcome this problem.

Abstract Purpose: To investigate the short-term results of accelerated crosslinking (A-CXL) treatment for progressive keratoconus in the pediatric and adult age groups. Materials and methods: The records of the 62 eyes of 40 patients who had undergone the A-CXL procedure (9 mV/cm2, 10 min) for progressive keratoconus between January 2015 and January 2019 were evaluated retrospectively. The patients were divided into 2 groups as the pediatric group (aged 17 years or less) and the adult group (aged 18 years or more) for statistical analysis. Pre- and post- 12th month A-CXL best-corrected visual acuity (BCVA), maximum keratometry (Kmax), sim K1, sim K2, corneal thickness at the thinnest point (thCT), and corneal astigmatism (CA) values of the patient groups were recorded. Results: The 29 eyes of 16 patients were included in the pediatric group and the 33 eyes of 24 patients were included in the adult group. The mean age was 13.50±3.05 years in the pediatric group and 23.58±4.37 years in the adult group. A significant improvement in BCVA and a significant decrease in thCT values were present in both groups 12 months after the surgery compared to the preoperative period. A decrease was present in the Kmax, sim K1, sim K2 and CA values in the pediatric group, but was not statistically significant. The decrease in Kmax, sim K1 and sim K2 values compared to the preoperative period was significant in the adult group, but the decrease in CA values was not significant. When the two groups were compared at the end of 12 months, only the sim K1 value was significantly lower in the adult group, and there was no significant difference between the other measurements. Conclusions: Better visual acuity improvement, a higher flattening rate, and less progression occur after 12 months with A-CXL treatment for progressive keratoconus in the adult age group compared to the pediatric age group.

Background The natural history of disease in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remained obscure during the early pandemic. Aim Our objective was to estimate epidemiological parameters of coronavirus disease (COVID-19) and assess the relative infectivity of the incubation period. Methods We estimated the distributions of four epidemiological parameters of SARS-CoV-2 transmission using a large database of COVID-19 cases and potential transmission pairs of cases, and assessed their heterogeneity by demographics, epidemic phase and geographical region. We further calculated the time of peak infectivity and quantified the proportion of secondary infections during the incubation period. Results The median incubation period was 7.2 (95% confidence interval (CI): 6.9‒7.5) days. The median serial and generation intervals were similar, 4.7 (95% CI: 4.2‒5.3) and 4.6 (95% CI: 4.2‒5.1) days, respectively. Paediatric cases < 18 years had a longer incubation period than adult age groups (p = 0.007). The median incubation period increased from 4.4 days before 25 January to 11.5 days after 31 January (p < 0.001), whereas the median serial (generation) interval contracted from 5.9 (4.8) days before 25 January to 3.4 (3.7) days after. The median time from symptom onset to discharge was also shortened from 18.3 before 22 January to 14.1 days after. Peak infectivity occurred 1 day before symptom onset on average, and the incubation period accounted for 70% of transmission. Conclusion The high infectivity during the incubation period led to short generation and serial intervals, necessitating aggressive control measures such as early case finding and quarantine of close contacts.

Chicken infectious anemia (CIA) is an economically important disease affecting poultry, especially young chicks, characterized by poor weight gain, anemia, immunosuppression and production losses. Recent reports indicate that the virus is emerging and re-emerging worldwide.  Also, scarce reports regarding the molecular detection and epidemiology of virus from India are available. The aim of this study was to determine the prevalence of the virus in the commercial poultry farms of the country employing polymerase chain reaction (PCR). Out of the suspected 424 field samples tested from 12 different states of the country during the last five years (2007-2012), 311 (73.3%) samples were found positive for CIAV-DNA indicating the wide prevalence of the virus in India. The age wise prevalence of the virus indicated high prevalence in young chicks of up to three weeks (80.3%) of age compared to 3-7 (66.6%) and 7-12 (25%) week age groups. Being an immunosuppressive emerging pathogen circulating among the poultry flocks of the country, suitable prevention and control measures need to be adopted timely. This is a first elaborative report on the molecular epidemiology of CIAV in poultry flocks of the country. Extensive epidemiological studies are suggested to know the magnitude of the virus affecting poultry industry of the country, and design and formulate effective disease prevention and control strategies to reduce economic losses being caused by emerging virus.

Abstract Aim: This study was designed to assessthe prevalence of various oral habits among 3-6 years old school childrenin Chandigarh Method: Fifteen different public schools were randomly selected among 45 public schools in Chandigarh area from where 938 children (3-6 yr) were randomly selected (511 boys and 427 girls) with the objectives of recording the prevalence of oral habits. Statistical analysis was carried out using SPSS 10.0 software and the statistical significance of oral habits as related to age groups and sex were calculated by using ANOVA test. Results: The overall prevalence of oral habits in children was 11.7%. Nail biting was the commonest habit (5.5%) followed by thumb sucking (4.05%), tongue thrusting (1.8%), mouth breathing(0.3%) and lip biting(0%). Also, there were no significant differences between boys and girls with respect to prevalence of oral habits. However, a significant difference was observed between different age groups with respect to the prevalence of oral habits. Conclusions: The data revealed that a significant percentage of the children had deleterious oral habits which can contribute towards the development of malocclusion. This helps in identifying children who are in need to intercept the oral habits at earliest to avoid future occurrence of malocclusion.

It was the purpose of this study to investigate differences between visual perception of static (non-moving) and dynamic (moving) two-dimensional objects at several ages. This study specifically assessed the ability of four age groups to perceive figure-ground: Elementary 1 (age 6 to 7 yr.); Elementary 6 (age 11 to 13 yr.); College (age 18 to 22 yr.); Elderly Adult (age 66 to 79 yr.). A total of 169 Ss were tested. A test of visual perception of figure-ground was selected and adapted to a dynamic condition. Results showed there was a significant difference between performance on the static and dynamic tests of visual perception across all age levels, with fewer errors made on the dynamic test. There was a significant difference in performance between ages. It was concluded that there is a difference between static and dynamic visual perception of figure-ground at the ages studied and that perception of figure-ground tends to improve with age.
