Experimental Yersinia pseudotuberculosis enteritis in laboratory animals
AEJ Okwori, SE Agina, MO Odugbo, AO Olabode, LH Lombin
African Journal of Biotechnology , 2007,
Abstract: The course of in vivo pathogenicity of Yersinia pseudotuberculosis in groups of rabbits and gunnea pigs were examined. One group of the animals was infected orally with 108 cfu/ml of test organism and the second group with standard reference strains. The third group was dosed with clean water as negative control. Both controls and Y. pseudotuberculosis infected animals were closely monitored for clinical signs for three weeks during which loss of body weight, rise in temperature, ruffling of fur were noticed. Pure isolates of the organisms were re-isolated from the faecal samples of the infected rabbits and guinea pigs. Animals orally fed with clean water showed no symptoms of yersiniosis. Rabbits infected with Y. pseudotuberculosis showed signs of illness while guinea pigs did not show any clinical sign. Visceral organs of infected rabbits showed enteritis with necrotic lesions but no pathological changes were observed in all guinea pigs including the controls. In the clinically ill animals, tissues analyzed demonstrated polarized profile and inflammatory cell influx throughout the course of the test. These findings should assist the Veterinary Pathologist recognize suspected cases of enteritis due to Y. psuedotuberculosis in the field among similar animal species.

African Journal of Biotechnology , 2008,
Abstract: Phenotypic diversity among 69 field isolates plus 3 vaccine strains previously identified as Pasteurella multocida were investigated by extended phenotypic characterization. The field isolates were obtained in Nigeria from chickens (15 isolates), quail (5 isolates), cattle (31 isolates), goats (7 isolates), sheep (8 isolates), rabbits (3 isolates) and the vaccine strains (3 isolates), which are used as prophylaxis against fowl cholera and haemorrhagic septicaemia diseases. Consistent results were obtained for all isolates in the test for Gram reaction, oxidase, catalase, urease, no growth on MacConkey agar and nitrate reduction. All isolates also fermented D-glucose, D-mannitol, and sucrose but failed to ferment lactose. The isolates differed in their ability to ferment L-arabinose, D-dulcitol, D-sorbitol, D-xylose and in the production of indole and H2S in triple sugar iron agar resulting in the identification of 8 biochemical types or biovars. Dulcitol and sorbitol fermentation patterns meant that the isolates (including the vaccine strains) could be identified as subspecies Pasteurella multocida multocida (74%), Pasteurella multocida septica (18%), or Pasteurella multocida gallicida (8%). The subspecies P. m. multocida was demonstrated in all the animal species and the vaccine strains. Among the animal species studied, P.m. septica was demonstrated in all but the leporine species while P.m. gallicida was demonstrated only in the avian and ovine species. This characterization study adds to the considerable phenotypic variability that has been reported within the P. multocida taxon.

Nigerian Veterinary Journal , 2011,
Abstract: A study was designed to determine the prevalence of Campylobacter species isolated from cattle in Plateau state, Nigeria. From April, 2008 – March, 2009, 352 rectal swab samples were randomly taken from cattle in 18 herds in Plateau State, Nigeria and analyzed for the presence of Campylobacter species. Out of the 352 samples tested, 65 (18.5%) were identified as Campylobacter species using biochemical tests; with 52 (80%) as C. jejuni and 13 (20%) as C. coli. Of the 65 isolates, 63 (97%) were confirmed by polymerase chain reaction (PCR). Out of the 18 cattle herds tested, 12 (66.7%) were positive. The results of the study also showed that the prevalence was significantly (p<0.05) higher in calves (25%) than in adults (12.2%).

Investigations On The Carrier Rate Of Pasteurella Multocida In Black Rats (Rattus Rattus) In A Commercial Quail Farm
ES Mwankon, MO Odugbo, LD Jwander, V Olabode, SO Ekundayo, U Musa, T Spencer, SI Isa, A Kaikabo, S Boss
African Journal of Clinical and Experimental Microbiology , 2009,
Abstract: The aim was to investigate the level of Pasteurella Multocida infection from two anatomic sites of black rats (Rattus Rattus), popularly referred to as house or roof rats in a commercial quail farmhouse with recurrent fowl cholera outbreaks and also to evaluate the association between the Pasteurella Multocida found in rats co-habiting quail poultry houses and isolates from outbreaks of fowl cholera. Thus 100 pharyngeal and 100 rectum swabs samples taken from rats co-habiting farmhouse were obtained and evaluated bacteriologically for isolation of P. multocida; 54% of pharyngeal swabs and 62% of rectum swabs were positive for P. multocida. Extended phenotypic characterization of the isolates confirmed the presence of subspecies P. multocida multocida. Subspecies Pasteurella Multocida septica and gallicida were not encountered. Ramdom serotyping of 5 isolates each from the two sites confirmed serotypes A:4. Fowl cholera outbreaks were confirmed on the quail houses and carrier rats had the same Pasteurella Multocida subspecies and serotype as the infected quail. The public health significance of the finding is also discussed. African Journal of Clinical and Experimental Microbiology Vol. 10 (1) 2009: pp. 2-9

Jos Journal of Medicine , 2011,
Abstract: Aim: To evaluate the outcome of cataract surgery in terms of restoration of visual function in the operated eye in relation to the rank and experience of surgeons. Methodology: Four centres were selected using stratified random sampling technique. Consecutive patients, who had cataract extraction from 1st October 2002 - 31st March 2003, were recruited. The study instrument was a pre-tested structured questionnaire. Preoperative visual acuity (VA), type of cataract, type of surgery, official rank of surgeon, peri-operative events, postoperative events and physiological outcome were documented. Result: 200 patients were recruited. Mean age was 61.08 years. 219 eyes were operated. 101(46.1%) were operated by consultants, 51(23.3%) by resident doctors and 67(30.6%) by diplomats. Intraoperative complications were encountered in 57 (26%) eyes. Of these 15(26.3%), 16(28.1%), 26(45.6%) eyes were operated by consultants, resident doctors and diplomats respectively. Of 161 eyes re-assessed six weeks after surgery, 86(53.4%) had good outcome (VA=6/18), while 18(11.2%) had poor outcome (VA<6/60) with available correction. 56(68.3%), 18(42.9%), and 12(32.4%) eyes operated by consultants, residents, and diplomats had a good outcome with available correction respectively (p<0.001). Of 125 eyes refracted six weeks after surgery, 92(73.6%) had good outcome while 11(8.8%) had poor outcome with best correction. 65(89.1%), 16(57.1%), and 11(45.8%) eyes operated by consultants, residents and diplomats had a good outcome with best correction respectively (p < 0.001). Conclusion: Resident doctors and diplomates encountered most of the intraoperative complications a

Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.101005
Abstract: This paper selects Hong Kong from 1999 to 2015 as the sample period, sets the variable to the private residential retail price index HP and the real estate related tax revenue HT, selects the multi-log logistic regression model method, empirically analyzes the profits tax, stamp duty, the impact of general rates and property taxes on the retail price index of private housing in Hong Kong. The results show that the real estate tax on the retention link has only a limited impact on the price of private housing. The promotion of property tax is more obvious, and the general difference is less affected. The real estate tax on the transaction link has a significant impact on housing prices. Profits tax has a significant positive effect, and stamp duty also has a driving effect, but the effect is weak. Increasing the tax on the transaction link will stimulate the housing price to rise further. According to the empirical results, this paper believes that the Hong Kong government should further clarify the role of real estate tax, give full play to the government’s functions in the real estate market, simplify the real estate tax system, and improve the property tax package, in order to play a role in the real estate tax to suppress housing prices.

Sokoto Journal of Veterinary Sciences , 2008,
Abstract: A study was undertaken to examine the isolation rate of Klebsiella pneumoniae from birds affected by natural outbreaks of highly pathogenic avian influenza (H5N1) that occurred in Nigeria between December, 2006 and July, 2007. A total of 100 birds from 114 commercial, backyard and free range flocks infected with H5N1 virus within the study period were sampled. A total of 600 tissues (heart, lung, spleen, liver, trachea and intestine), 100 each from the 100 birds were collected for bacteriology. Data generated was entered into Microsoft excel, while descriptive statistical analysis was conducted using SPSS (Version 12.01). Klebsiella pneumoniae was isolated from 9 (1.5%) samples. The organism was isolated from the liver, lungs and trachea of commercial layers and turkeys. During the HPAI outbreaks, Klebsiella pneumoniae was isolated from 9 different flocks with a total of 21,805 birds, mortality rate of (7.3%) and proportionate mortality rate of (2.5%). The bacterium was not isolated from H5N1 free flocks which served as control. The result of this study indicated that Klebsiella pneumoniae may have acted as a secondary pathogen to aggravate the clinical signs during H5N1 outbreaks that occurred in Nigeria.

Jos Journal of Medicine , 2012,
Abstract: Aim: To determine the prevalence of presbyopia, refractive errors and usage of spectacles among Commercial Intercity Vehicle Drivers in Jos-Nigeria. Method: A descriptive cross-sectional survey of commercial intercity vehicle drivers at the Bauchi Road Motor Park, Jos, was undertaken in November 2006. The study instrument was a semi-structured questionnaire. Information obtained included demographic data, operational route, history of involvement in road traffic accident (RTA), cause of RTA and ocular history, type and usage of corrective spectacles if any. Each participant had a detailed ocular examination. Result: Up to 221 of 268 drivers were recruited (coverage: 82.5%). Their age ranged from 20-90 years (mean: 44.2 years, SD 9.2). 78 (35.3%) persons complained of difficulty in reading small prints while 17(7.7%) persons complained of poor distant vision. Ten (4.5%) drivers had a visual acuity of <6/12 and thus did not qualify to possess a driving licence. Presbyopia was the most common ocular diagnosis observed in 94(42.5%) persons. Most presbyopes 63 (67.0%) needed +1.50 to +2.00 DS correction. Only 10(10.6%) presbyopes had spectacles with presbyopic correction. Six (2.7%) persons had myopia while one person (0.5%) had unilateral aphakia. Conclusion: The prevalence of Presbyopia is high. Myopia is the most common refractive error. Usage of corrective spectacles is very low. There is an urgent need for enforcement of minimal visual standards for the purpose of certification and re-certification for drivers licence in Plateau State and Nigeria at large.
