Karanja DN;, Ngatia TA;, Wabacha JK;, Bebora LC. "The Sensitivity And Specificity Of Clinical Signs, Post-mortem Findings And Isolation Of Escherichia Coli In Diagnosing Edema Disease Of Swine."; 2008. Abstract

Commonly used diagnost ic techniques for edema disease in Kenya were tested for their sensitivity and specificity on 84 pig carcasses submitted to Department of Veterinary Pathology and Microbiology between June 2004 and June 2007. Clinical signs gathered from anamnesis, post - mortem lesions revealed at autopsy and E. coli isolated from intestinal contents and characterized using biochemical tests and polymerase chain reacti on were compared using receiver - operating characteristic analyses. A combination of clinical signs, post - mortem findings and isolation of E. coli carrying F18 and shiga - toxin type II variant genes were used as gold standard test. Forty nine (58.3%) cases w ere diagnosed as edema disease, based on clinical signs and post - mortem findings . Of these, thirty eight (77.6%) had variable amounts of edema in various body si tes and clinically, twenty six (53.1%) had neurological signs, 18 (36.7%) were found dead, 3 ( 6.1%) had swollen eyelids and 2 (4.1%) expressed respiratory distress. Hemolytic E. coli carrying the tested genes were isolated from thirty one (62.2%) of these cases. Presence of edema in various body cavities and observation of defined clinical signs h ad 75.3% and 57.4% sensitivity, respectively. Considered individually, the sensitivity was 64.7% for found dead, 50% for neurological signs and 84.4% for isolating hemolytic E. coli. All had a specificity of 81.3%. The results show that none of the diagnos tic techniques had the expected 100% sensitivity and specificity, but isolation of hemolytic E. coli may be an important screening test for suspected edema disease cases

Contam. Toxicol; 2006. Abstract
A study to evaluate alternative health interventions for the control of sarcoptic mange and gastro-intestinal nematodes in smallholder pig herds was carried out in Kikuyu Division of Kiambu District, Kenya. A total of 40 herds were randomly allocated, by a simple random strategy, to 3 treatment groups and 1 control group. Each group comprised of 10 herds. Herds in group 1 (control) were treated with a placebo, physiological saline. In group 2, control of nematodes and mange was attempted through the use of ivermectin, while in group 3, nematodes and mange were treated through the use of an anthelmintic (piperazine hydrochloride) and an acaricide (amitraz), respectively. In group 4, nematodes and mange were treated by using an anthelmintic (levamisole hydrochloride) and an acaricide (amitraz), respectively. The anthelmintic activity of ivermectin was not different (p>0.05) from that of levamisole. The proportion of pigs positive for mites was not different (p>0.05) between the ivermectin and the amitraz treatment groups. The overall costs for the treatments were US$0.50 for the ivermectin treatment, US$0.31 for the piperazine/amitraz combination treatment and US$0.26 for the levamisole/amitraz combination treatment. Amitraz/levamisole drug combination was the most cost-effective against sarcoptic mange and gastro-intestinal nematodes of pigs in the studied smallholder herds.

In: Faculty of Veterinary Medicine Biennial Scientific Conference, Nairobi, 3rd . Bull. Environ. Contam. Toxicol; 2004. Abstract
A longitudinal study was carried out in Kikuyu Division (a peri-urban area in central Kenyan highlands) between January 1999 and December 1999 to estimate the baseline parameters on reproductive performance of the sow, as well as health and productivity of grower and preweaning pigs of smallholder herds. Data were collected on 155 breeding pigs, 795 grower pigs and 801 preweaning piglets in 74, 50 and 40 smallholder herds, respectively, using record cards that were updated during monthly visits. The sow-level medians were: weaning-to-service interval 3 months; interfarrowing interval 6.4 months; number of live-born piglets 9.0; and number of piglets weaned per litter 7.5. The piglet crude morbidity incidence risk was 29%. The cause-specific incidence risks for the important health problems encountered in preweaned piglets were diarrhea (4.3%), pruritus (17.1%), and skin necrosis (4.2%). The estimated crude mortality incidence risk to 8 weeks of age was 18.7%. The cause-specific mortality incidence risks to 8 weeks of age for the important causes of mortality were overlying (9.9%), savaging (2.4%), unviable piglets (2.0%) and unknown (1.9%). Overall, 78.8% of the total live-born piglet mortality occurred during the first week postpartum with 69% of these deaths being caused by overlying. The grower-pig crude morbidity incidence risk was 20% and the cause-specific incidence risks of the important health problems encountered were gut edema (1.3%), pruritus (21.1%), and unknown (2.3%). The crude mortality incidence risk was 3.8% and the important causes were gut edema and unknown causes (cause-specific mortality incidence risks of 1.3 and 1.6%, respectively). The median weight:age ratio and average daily weight gain for the grower pigs were 5.1 kg/month of age and 0.13 kg/day, respectively. For preweaning pigs, the median average daily weight gain was 0.13 g/day.

Bull. Environ. Contam. Toxicol; 2004. Abstract
A study was conducted in sixty-two randomly selected herds in Kikuyu division, Kiambu District in Central Kenyan Highlands to obtain prevalence, spectrum and intensity of gastrointestinal helminths in pigs kept by smallholder farmers. Faecal samples from a total of 598 pigs of various age-group categories (piglets, weaners, growers and adults) were taken during a period of a 4 months in 1999 ad examined for helminthes eggs (EPG) using modified McMaster technique. Gastrintestinal helminth eggs wewre observed in 57 (91.9%) of the herds. The Helminths observed were Strongles (35.1%). Ascarids (10%), Trichuris (4), Strongloids (3.2%) and Tapeworms (0.3%). The overall prevalence of the helminaths was 43.5%. the prevalence among the various age groups differed significantly (p<0.01) with the highest prevalence in the weaners (55.6%) and the lowest in the piglets (22.9%). The prevalence of Strongles and Strongloids differed significantly (p<0.01) among the age groups. The highest prevalence for Strongyles was in the growers (41.7%) and the lowest in the piglets (22.9%) while the highest prevalence for lowest in the adults (0.8%). The prevalence of Ascarids differed significantly (p<0.01) among the age groups with the highest prevalence in weaners (27.8%) and the lowest in the piglets (3.6%). The prevalence of Trichuris worms was significantly (p<0.5) higher in the weaners than in the piglets. The high prevalence of the Gatrointestinal helmnths observed indicates the need to control these parasites due to their detrimental effects on productivity and also due to their public health significance.

The crude mortality incidence risk was 3.8% and the important causes were gut edema and unknown causes (cause-specific mortality incidence risks of 1.3 and 1.6%, respectively). The median weight:age ratio and average daily weight gain for the grower pigs were 5.1 kg/month of age and 0.13 kg/day, respectively. For preweaning pigs, the median average daily weight gain was 0.13 g/day.

A longitudinal study was carried out in Kikuyu Division (a peri-urban area in central Kenyan highlands) between January 1999 and December 1999 to estimate the baseline parameters on reproductive performance of the sow, as well as health and productivity of grower and preweaning pigs of smallholder herds. Data were collected on 155 breeding pigs, 795 grower pigs and 801 preweaning piglets in 74, 50 and 40 smallholder herds, respectively, using record cards that were updated during monthly visits. The sow-level medians were: weaning-to-service interval 3 months; interfarrowing interval 6.4 months; number of live-born piglets 9.0; and number of piglets weaned per litter 7.5. The piglet crude morbidity incidence risk was 29%. The cause-specific incidence risks for the important health problems encountered in preweaned piglets were diarrhea (4.3%), pruritus (17.1%), and skin necrosis (4.2%). The estimated crude mortality incidence risk to 8 weeks of age was 18.7%. The cause-specific mortality incidence risks to 8 weeks of age for the important causes of mortality were overlying (9.9%), savaging (2.4%), unviable piglets (2.0%) and unknown (1.9%). Overall, 78.8% of the total live-born piglet mortality occurred during the first week postpartum with 69% of these deaths being caused by overlying. The grower-pig crude morbidity incidence risk was 20% and the cause-specific incidence risks of the important health problems encountered were gut edema (1.3%), pruritus (21.1%), and unknown (2.3%). The crude mortality incidence risk was 3.8% and the important causes were gut edema and unknown causes (cause-specific mortality incidence risks of 1.3 and 1.6%, respectively).

A study was conducted in fourty randomly selected herds in a peri-urban area in the Central Kenyan highlands to obtain prevalence estimates of sarcoptic mange in pigs kept by smallholder farmers. A total of 476 pigs of various age-group categories were enrolled in the study. Diagnosis was based on physical examination for clinical signs indicative of mange infestation and on direct detection of Sarcoptes scabiei mites. Ninety per cent of the herds had clinical signs suggestive of sarcoptic mange and in 70% of the herds Sarcoptes scabiei var suis was positively identified. The results also indicated that 273 (57.3%) of the 476 pigs had clinical signs indicative of sarcoptic mange and 90 (18.9%) of the 476 pigs were positive for Sarcoptes scabiei var suis. The hypersensitive form of mange was more common than the chronic form. The direct examination technique to detect Sarcoptes scabiei var suis was more effective in weaners than in the other age categories of pigs. The results indicate that sarcoptic mange is a common problem in smallholder pig herds in Kikuyu Division of Kiambu District, Kenya.

The short-term farm level economic impact of Foot and Mouth Disease outbreak in a large-scale dairy scale dairy farm was assessed during the quarantine period (35 days) and 60 days after lifting of the quarantine. Direct and indirect areas that contributed to the financial losses were identified for the period of observation (85 days). The greatest direct financial impact was due to milk losses (42.0%) followed by purchase pf additional feeds (13.65) and culling of milking cows that developed chronic mastitis (12.5%). The other direct costs were; extra labout inputs (8.9%), veterinary fees (3.350, transport (3.05), death (3.0%), drugs (2.9%), abortions (1.4%) and chemicals (0.5%). The indirect costs (9.4%) were associated with the effects of the quarantine period on other farm enterprises.

Forty-two pigs in a herd of 117 displayed various clinical signs of progressive atrophic rhinitis. The main signs included sneezing, coughing, lachrymation, serous to mucopurulent nasal discharge, and nasal bleeding in 1 pig. Three pigs had lateral deviation of the snout, while 4 had brachygnathia superior with obvious deformation of the face. Four acutely affected weaner pigs appeared weak, while the 7 chronically-affected pigs appeared smaller than their apparently unaffected penmates of the same age. Treatment of the acutely affected pigs with long-acting oxytetracycline at 20 mg/kg body weight intramuscularly, repeated once after 7 days, reduced the severity but did not clear the sneezing from all the pigs. Fifteen pigs were slaughtered 2 months after the clinical diagnosis was made. The carcasses of the chronically affected pigs were about 15% lighter than those of the apparently normal pigs of the same age and from the same pen, which translated to a loss of 921.00 Kenya shillings per pig (US$13.7). Diagnosis of progressive atrophic rhinitis was confirmed by sectioning the snouts of randomly selected slaughtered pigs with obvious deformation of the snout. Sections were made at the level of the 1st/2nd upper premolar tooth. Varying degrees of turbinate atrophy, from mild to complete, were noted. Histopathology of the turbinates revealed metaplasia of nasal epithelium and fibrosis in the lamina propria.

The short-term farm level economic impact of Foot and Mouth Disease outbreak in a large-scale dairy scale dairy farm was assessed during the quarantine period (35 days) and 60 days after lifting of the quarantine. Direct and indirect areas that contributed to the financial losses were identified for the period of observation (85 days). The greatest direct financial impact was due to milk losses (42.0%) followed by purchase pf additional feeds (13.65) and culling of milking cows that developed chronic mastitis (12.5%). The other direct costs were; extra labout inputs (8.9%), veterinary fees (3.350, transport (3.05), death (3.0%), drugs (2.9%), abortions (1.4%) and chemicals (0.5%).

Treatment of the acutely affected pigs with long-acting oxytetracycline at 20 mg/kg body weight intramuscularly, repeated once after 7 days, reduced the severity but did not clear the sneezing from all the pigs. Fifteen pigs were slaughtered 2 months after the clinical diagnosis was made. The carcasses of the chronically affected pigs were about 15% lighter than those of the apparently normal pigs of the same age and from the same pen, which translated to a loss of 921.00 Kenya shillings per pig (US$13.7). Diagnosis of progressive atrophic rhinitis was confirmed by sectioning the snouts of randomly selected slaughtered pigs with obvious deformation of the snout. Sections were made at the level of the 1st/2nd upper premolar tooth. Varying degrees of turbinate atrophy, from mild to complete, were noted. Histopathology of the turbinates revealed metaplasia of nasal epithelium and fibrosis in the lamina propria.

Forty-two pigs in a herd of 117 displayed various clinical signs of progressive atrophic rhinitis. The main signs included sneezing, coughing, lachrymation, serous to mucopurulent nasal discharge, and nasal bleeding in 1 pig. Three pigs had lateral deviation of the snout, while 4 had brachygnathia superior with obvious deformation of the face. Four acutely affected weaner pigs appeared weak, while the 7 chronically-affected pigs appeared smaller than their apparently unaffected penmates of the same age. Treatment of the acutely affected pigs with long-acting oxytetracycline at 20 mg/kg body weight intramuscularly, repeated once after 7 days, reduced the severity but did not clear the sneezing from all the pigs.

This report concerns an outbreak that occurred during July/August 1997. Ten pigs from a herd of 181 pigs in a medium-scale, semi-closed piggery in Kiambu District, Kenya, contracted the clinical disease. The main clinical findings in affected pigs included: fever (40.5-41.8 degrees C), prostration, inappetence, dog-sitting posture, abortion, erythema and raised, firm to the touch and easily palpated light pink to dark purple diamond-shaped to square/rectangular spots on the skin around the belly and the back. Based on the pathognomonic skin lesions, a clinical diagnosis of swine erysipelas was made. The diagnosis was confirmed by the isolation of Erysipelothrix rhusiopathiae organisms from the blood and skin biopsies taken from the affected pigs. Response to treatment with a combination of procaine penicillin and dihydrostreptomycin at the dosage rate of 20,000 IU/kg body weight (based on procaine penicillin) for 3 days was good and all the affected pigs recovered fully. The farm was placed under quarantine to prevent spread of the disease
