Publisher: 1991Dissertation note: Seroprevalence of brucellosis in 541 cattle, 708 sheep, 780 goats and 63 human beings of one farm and 189 cattle, 125 buffaloes, 68 goats and 51 human beings of the other farm was studied. The various serologic tests used for this investigation included the slide agglutination test for initial screening, and the standard tube agglutination test (SAT) and the enzyme-linked immunosorbent assay (ELIS1) for further processing of the sera i.e. quantitation of Brucella antibodies. The higher prevalence of the disease was observed in cattle than buffaloes while goats outnumbered sheep in this respect. The prevalence of the disease in human beings was found to be related positively with the prevalence of the disease in animals.
The overall prevalence of the disease in sheep of one farm was found to be 35(4.947.), 27(3.817.) and 29(4.097.), respectively, by the slide agglutination, standard tube agglutination test (SPIT) and ELISA. Goats of one farm displayed a prevalence of 202(25.897.), 173(22.187.) and 183(23.467.) and that of the other, 3(4.417.), 2(2.947.) and 2(2.947.), respectively, by the slide agglutination, SPT and ELISA. This remarkable difference in the incidence of the disease in two farms may be attributed to the difference of
sample size.
A prevalence of 127(23.48%), 87 (16.08%) and 91(16.82%) was recorded in cattle of one farm while 30(15.877.), 19(10.057.) and 20(10.587.) cattle of the other proved positive respectively to the slide agglutination, SpiT and ELIS. In buffaloes, a prevalence of 17(13.67.) and 11(8.87.) and 11(8.97.) was noted by the slide agglutination, ST and ELISA tests, respectively. While interpreting the age-group relationship of the disease, it was found that adult and old animals had a higher prevalence than the young animals. Owing to the small number of male serum samples, the sex- based analysis of the disease could not have been adequately discussed
The enzyme linked immunosorbent assay was found to be a sensitive approach in detecting anti-Brucella antibodies than the slide agglutination and standard tube agglutination tests. The ELISA titres were, on average, about 8 times higher than the corresponding SAT titres
The results of this study have revealed an alarming prevalence of brucellosis in animals of farms which calls for an emergent response of experts for reappraisal and reassessment of the present brucellosis control situation, especially when the disease is an important zoonosis and a potential threat to the human health.

Publisher: 1986Dissertation note: The study was undertaken to detrmine the Salmonellae carrier state in camel, in an attempt to understand the epidemiologica] role played by this animal in transmission of Salmonellosis to other animals and man
The faecal and mesenteric lymph gland samples were collected from 100 apparently healthy camel a slaughtered at Lahore abattoir. Each sample was enriched in selenite troth arid isolates passed through a series of differential and selective media for an effective primary isolation and purification of Saimonellae.
The identification of isolates was carried out on the basis of their morphology, biochemical characteristics and serology. The serology was carried out using standard polyvalent "0", and "H" group arid type specific antisera by rapid spot agglutination test.
The Salinonellae were isolated from isolated from any faecal samples, giving an isolation percentage of 2.0 in this species.
On the basis of biochemical studies and serology it was observed that both the isolated strains of Salmonella belonged to Salmonella typhimrium.
The camel was found to be carrier of Salmonella typhimurium and could act as a source of infection for animals and man. Further work on large scale is recommended.

Publisher: 1988Dissertation note: Blood samples and laryngeotracheal material of 500 buffaloes, slaughtered at various abattoirs of Lahore, in the month of February, 1988 through June, 1998, were collected and processed for ascertaining carrier condition for Past. Multocida and its effect on the serum antibody levels.
Of the total number of buffaloes examined, the organism was isolated from 23 (4.6 per cent) animals when the laryngeotracheal region was swabbed directly after slauther.
The erum samples from 23 past. Multocida carrier animals were examined for the presence of specific antibodies. Consequently 19 (82.60%) animals proved positive. A similar examination was conducted on sera of 60 non-carrier animals, where, only 5 were found positive. It is hopefully thouth that the findings of this project will provide utilitarian information regarding the role of carriers in epidemiology of HS and its control.

Publisher: 1986Dissertation note: Five hundred samples of mesenteric lymph nodes of sheep and goats , 20 from each species , slaughtered at Lahore abattoir, were bacteriologically examined to determine the Salmonella carrier state in healthy sheep and goats. Nine strains of Salmonellae belonging to two serological types i.e. Salmonella typhimurium (l.40%) and Salmonella anatum (0.40%), were isolated. The incidence of Salmonellosis in sheep and goats were recorded as 2.40% and 1.20% respectively.
The media used for primary isolation and purification were Selenite broth, Bismuth sulphite agar, Brillient green agar, MacConkey agar and Nutrient agar. Results of Triple sugar iron agar and Urease test gave a preliminary confirmation of Salmonella organisms. Sugar fermentation reactions, Methyl red and Voges Proskauer tests were also employed for the confirmation of isolates. The Serological identification was carried out with the help of standard antisera manufactured by ' Research Institute of Infectious and Parasitic Diseases Sofia, Bulgaria. Further work on much larger scale is recommended.

; Nature of contents: ; Literary form: Publisher: 1993Dissertation note: New Castle disease still continues to he serious economic threat to poultry industry throughout the world due to its high morbidity and mortality rate.
In Pakistan different vaccines are being used to control this disease. Now-a-days different N.D. vaccines are being imported and used on large scale in Pakistan without; knowing their immunogenic response.
The present study with this project was conducted to evaluate the immunogenecity of our locally prepared Mukteswar strain of N. D. vaccine with imported Deivax Clone LZ 58 and Lasota strains of New Castle disease vaccines. To three groups "A", W. "C", comprising of 25 chicks each Nukteswar, 1,Z Clone 58 and Las toa ND vaccines were administered intramuscularly and group D was kept as unvaccinated control.
Mukteswar ND vaccine gave high imanuanogenic response on day 14 (P.V) with Geomean HI titre of 438 which persisted on day 2i. LZ Clone 68 ND vaccine gave a Geomean HI Sitre of 362 on day 14 which also persisted on day 21.
Laston vaccine gave a Geomean HI titre of antibodies on 14th day as 262 which persisted on day 21 (P. V) which was the lowest as compared to other two vaccines. All the three vaccines resisted challenge. Therefore it is observed from the above findings that Liukteswar strain of ND vaccine gave better results as compared to Clone and Lasota imported vaccines and their import on such large scale be stopped.

Material type: ; Format:

Publisher: 1990Dissertation note: Seroprevalerice of brucellosis--- a disease of great zoonotic potentials and implications----- on 552 cattle, 523 buffaloes, 554 sheep, 524 goats and 87 butchers (working at the abattoir) was studied. Various serologic tests employed for this investigation comprised the slide agglutination test for primary screening and the standard tube agglutination test (SAT) and the enzyme-linked immunosorbent assay (ELISA) for further processing of the sera i.e. quantitation of anti-Brucella antibodies. The slide agglutination test recorded a higher prevalence of the disease whereas both the SAT and ELISA displayed a similar picture of the prevalence. A higher prevalence was noted in buffaloes than cattle while goats outnumbered sheep in this respect.
The prevalence of the disease by agglutination test was found to be 27(4.89), 25(4.527.), 23(4.397.) and 9(10.34X) in cattle, sheep, goats and butchers, respectively, whereas SAT and ELISA registered a prevalence of 18(3.447.), 9(1.627.) and 15(2.067.) respectively buffaloes, sheep and goat!3; however, in human the slide 37(7.07), buffaloes, both the 12(2.177.), in cattle, beings, the
SAT revealed an incidence of 5(5.747.), while the ELISA figured it to be 4(4.59). The influence of various epidemiological factors such as age, sex etc. was proved. Female animals exhibited a higher prevalence (2.97, 3.79, 1.91 and 3.16 per cent in cattle, buffaloes, sheep and goats respectively by the SAT and ELISA) in contrast to the male animals which reflected a lower one (1.41, 1.98, 1.07 and 2.08 per cent, respectively). In cattle and buffaloes above
3-years-age, the prevalnece of brucellosis was recorded to be 2.95 and 4.30 per cent respectively, whereas, sheep and goats above 9 month age demonstrated a prevalence of 2.27 and 3.62 per cent respectively by the SAT and ELISA. Younger animals were all negative.
The enzyme linked immunosorbent assay was found to be a more reliable, sensitive and specific approach than the slide agglutination and standard tube agglutination tests since the former either did not at all react to the sera with a SAT titre of lesser than 1 in 40 or expressed a titre of I in 80 (on a few sera only) which was not of any diagnostic value. The ELISA titres were, on average, about 8 times higher than the corresponding SAT titres.
The results of this study have revealed an alarming prevalence of brucellosis in our animals, which calls for an emergant response of experts for reappraisal and reassessment of the present brucellosis control situation, especially the disease being an important zoonosis and potential threat to the human health.
