A cross-sectional study was conducted between November and December 2012 in Musoma district of Mara region, Tanzania with the aim of determining seroprevalence of Contagious Caprine Pleuropneumonia (CCPP) in healthy indigenous goats at a time of sampling and potential within herd risk factors for the disease. A total of 320 goat sera were examined for the presence of specific antibodies against Mycoplasma capricolum subsp. capripneumoniae using competitive ELISA. Of the sera tested, 206 (64.4%) were positive for CCPP. The seroprevalence of CCPP was significantly (P < 0.05) higher in adult (54.9%) than in young (45.1%) goats and also higher in male (66.7%) than female (63.7%) goats (P<0.05). With respect to goats’ origin, the serological prevalences were 74.6 %, 64.8% and 55% for Kiagata, Makongoro and Nyanja divisions respectively. In conclusion, the present study has shown that the prevalence of CCPP in Musoma district is high. Furthermore, control and preventive measures should be devised in order to mitigate the impact of the disease.

Cryptosporidium spp . and Giardia duodenalis are important parasites infecting a wide range of domestic animals worldwide. The aim of the present study was to determine the occurrence of Cryptosporidium spp . and Giardia parasites in different domestic animals living in close contact with humans within rural/semiurban communities in Kafue district in Zambia. A single faecal sample per animal was collected from pigs, goats, dogs, ducks, chickens and pigeons and analysed by Merifluor C ryptosporidium/Giardia immunofluorescence antibody assay for the simultaneous detection of these parasites. The faecal consistency was noted and scored as non-diarrhoeic or diarrhoeic. A total of 236 samples were collected. Cryptosporidium spp . oocysts were detected in pigs (11.5%, 17/148), goats (5.9%; 1/17), ducks (10.0%; 3/30) and chickens (14.3%; 2/14) while Giardia cysts were detected in pigs (8.1%; 12/148), goats (5.9%; 1/17), dogs (25.0%; 5/20) and ducks (6.7%; 2/30). Diarrhoea was not associated with either infection. Age was also not associated with either infection except in dogs where Giardia infection was only detected in animals aged less than six months (p=0.009). It is concluded from this study that Cryptosporidium spp . and Giardia parasites are prevalent among domestic animals reared within communities in Kafue district thereby constituting a potential source for zoonotic infections.

The authors would like to report an unusual incidence of severe tibio-tarsal rotation in a 14-month old ostrich hen designed for slaughter and housed on an ostrich farm in Poland (51o43´N, 15o33´E, October 2007). The ambient indoor and exterior temperature from 0600-1800 was recorded at 2-hr intervals as 20.40 (mean) ± 0.12 (SEM) and 14.98 ± 1.35oC, respectively. The exterior relative humidity recorded likewise was 50.00 ± 0.67%. The pathology expressed itself in the left limb with an outward angle of rotation in the foot of 92o (Figures 1-3). The perpendicular height of the hen, and length of the right femur, tibia, metatarsals, toe and claw lengths were 120 vs . 140, 59 vs . 56, 36 vs . 42, 10 vs . 5.5, 6 vs . 11 and 3 vs . 4.5 cm, respectively by comparison with an age-matched normal hen.

The characteristics of markets for free-range pigs in Busia District, Kenya were determined using retrospective analysis of veterinary records, key informant interviews and questionnaire survey. A total of 8,377 pigs were slaughtered between 2001 and 2005, which accounted for 27% of all the livestock slaughtered and inspected by the government officers. Loss of fetuses was recorded for 13% of slaughtered pigs and the loss was attributed to ignorance on pregnancy diagnosis. Although most of the money (82%) generated by the veterinary department arose from meat inspection fees, constraints including limited personnel and lack of enough vehicles were observed. The marketing system comprised of farmers, middlemen, slaughter-slab owners and butchers, while the government played the role of meat inspection. Majority of the butchers were males (94%) with a mean age of 39 (range: 21-74) years. The majority (63%) had a primary school level of education. The average net income per annum for each butcher was 887 USD and the profit earned per pig was 3.8 USD. The major constraints which affected the butchery business included conflicts with regulatory authorities, high government levies, erratic number of slaughter pigs mainly due to African Swine Fever (ASF) and poor mode of transportation. There is a need to address these constraints especially the control of ASF, reduction in levies and provision of incentives to improve pig trade in Busia District.

A total of 25 commercial layer carcases from seven poultry farms in Morogoro municipality were examined for gross and histopathological changes. Grossly, splenomegally, renomegally and hepatomegally were striking features. Both the liver and spleen were almost twice the size of normal organs. The surfaces of the liver, spleen, kidneys, lungs and the heart had yellowish white to grey multifocal and focally extensive patches of variable sizes. The lungs were consolidated. Histologically, the liver, spleen, kidneys, lungs, and the heart had heavy infiltration of large lymphocytes with abundant cytoplasm and poorly stained eosinophilic cytoplasm. There were also small lymphocytes with scant cytoplasm and deeply stained eccentrically placed nuclei and numerous mitotic figures. The history, clinical signs, and pathologic features were suggestive of avian lymphoid leukosis.

A total of 416 sheep and 624 goats under different management systems in peri-urban areas of Makurdi were examined for ectoparasite infestations for a period of 6 months, October to March 2004. Ninety one (21.9%) sheep and 149 (23.9%) goats were infested with various types of ectoparasites. Ectoparasites identified, and the number of sheep infested were ticks 37 (40.7%), fleas 20 (22.0%), lice 18 (19.8%) and mites 16 (17.6%). For goats, they were ticks 47 (31.5%), fleas 34 (22.8%), lice 39 (26.2%) and mites 29 (19.5%). The commonest species of ticks observed were, Rhipicephalus evertsi and Amblyomma variegatum while the commonest of mites was Psoroptes communis . Lignognathus species and Bovicola species were the lice observed, and the fleas was Ctenocephalidis felis . The level of infestation was highest in extensive (27.0%) and lowest in intensive (7.2%) systems of management. The possibility of transmission of arthropod borne pathogens to humans is high considering the common co-habitation of the animals and man. Routine and strategic control measures should be factored into production to increase profit and health.

Faeces from 192 ducks feeding around 10 wells and 6 ponds in peri-urban areas of Makurdi town, North-Central Nigeria were randomly sampled during the dry season period of October, 2006 to March, 2007. The samples were cultured for Campylobacter jejuni , followed by characterisation of positive samples. The overall prevalence was 63.5%. Prevalence rates were very high, 61.7% and 66.7% for faeces obtained from the ducks around wells and ponds respectively. The prevalence rate was highest in the month of February, where 80.0% and 83.3% of the faecal samples were positive for wells and ponds, respectively; prevalence rates were lowest (40.0%) in the month of October for wells and 50% for ponds in March. Campylobacter jejuni infection in ducks was highly associated (P = 0.36) with diarrhoea as Campylobacter was isolated from 76.7% of cases with diarrhoea. Water samples from 66.7% of the wells and 83.3% of the ponds were also Campylobacter -positive. The presence of this pathogen in duck faeces and sources of drinking water pose a very serious public health problem. There is therefore a need to intensify public health education and protect the wells and ponds against contamination and pollution.

The current study investigated the histology of various thoraco-visceral tissues of 85 dead-in-shell ostrich embryos. The average embryo length was 16.3 cm and weight 734.2 g. The average egg dimensions were: a) Smaller class - 1,560 g weight, 155.1 cm length, and 128.4 cm width; and b) Larger class - 1,592 g weight, 156.1 cm length, and 129.5 cm width. There were visible numerous lymphocytic infiltrations in the kidney cortex. No patho-morphological alterations were observed in the trachea or tongue. The gizzard had lymphocytic infiltrations and myopathy. The heart muscle showed anasarca and myopathy. We suggest a genetic element possibly associated with a nutritional imbalance and a microbial spoilage of eggs that is predisposing to the dead-in-shell embryos on the farm.

Three calves were infected with 2000, 3000 and 4000 metacercariae of Fasciola gigantica . Two other calves were left as uninfected controls. All calves were kept indoor for 23 weeks. During this period, serial samples of plasma and faeces as well as body weight gains were taken. Eggs were first detected in the faeces of infected calves on week 13 post infection (PIW13). In the infected animals, AST activity rose from an average level of 57.5 units/ml to 71 units/ml whereas GGT rose from an average level of 7.8IU/l to 65.6 IU/l. The percentage increase in body weightS of all calves were comparable during the first nine weeks after infection. Between PIW 9 and 13, the infected animals gained weight between 0.6% and 0.7% of their initial body weights. The percentage increase in body weights of the controls during the same period was between 11% and 17%. It was concluded that serial plasma enzyme patterns are useful in evaluating the different stages of F. gigantica infections.
