Abstract
The present prospective case control study was carried out to assess the role of C-reactive protein (CRP) level as a diagnostic and prognostic tool of tuberculous patients. The study was conducted in the Department of Paediatrics over a period of one year. Total 60 persons were included. Case was 30 and control was 30. Out of 30 tuberculosis patients 18(60%) had pulmonary tuberculosis, 6(20%) had abdominal TB, 3(10%) had pleural effusion and 3(10%) had tubercular lymphadenopathy. CRP was positive>6 mg/L in 25(83.3%) cases. CRP level was negative after 4 weeks of treatment. There is significant difference at p<0.001 in serum CRP level in between tuberculosis and healthy children. The study concluded that CRP level is a useful indication for diagnosis and prognosis of tuberculous patients.

Abstract
Aim: The present study was conducted to know the current scenario of classical swine fever (CSF) in Bengaluru Urban, Bengaluru Rural, Chikkaballapur, Madikeri, Mandya, Bagalkot, Gadag, Yadgir, Koppal, and Bidar districts of Karnataka with the using of both antigen and antibody ELISA. Materials and Methods: We collected 218 sera and 121 blood samples from pigs from 10 different districts of Karnataka. Screening of sera for CSF IgG antibody and whole blood for CSF virus antigen were carried out using the CSF virus (CSFV) antibody and antigen ELISA kits, respectively. Results: The mean seroprevalence was 41% (89/218) and prevalence of CSFV antigen in blood samples was 32% (39/121) for the 10 districts of Karnataka. Seroprevalence of 61%, 29%, 20%, and 21%; and antigen prevalence of 40%, 50%, 13%, and 12% were recorded for Bangalore, Mysore, Belgaum, and Gulbarga divisions of Karnataka, respectively. Conclusions: The study revealed an alarmingly high prevalence of CSF, both for the antigen (32%) and antibody (41%) in Karnataka. Southern Karnataka has the highest seroprevalence (61% in Bangalore and 29% in Mysore divisions), which confirms the endemicity of the disease in that region. This could be attributed to the intensive pig farming practices in the region as compared to Northern Karnataka (Seroprevalence of 20% in Belgaum and 21% in Gulbarga divisions), where the commercial pig farming is still in infantile stages.

Abstract
Aim: The aim was to evaluate lateral flow assay (LFA) as a field test for investigation of brucellosis outbreak in organized buffalo farm. Materials and Methods: A total of 153 serum samples were tested to detect the presence of brucella antibodies by LFA and three other serological tests i.e. rose bengal plate test (RBPT), protein G based indirect enzyme-linked immunoassay (iELISA), and competitive ELISA (cELISA). The performances of LFA and other serological tests were evaluated using OIE complaint cELISA as the gold standard. Results: Serological tests revealed 50% of the animals were seropositive for Brucella antibodies and correlated with clinical history of abortions, infertility, and productive failures. The newly developed assay showed 87.1% and 92.6% sensitivity and specificity, which was even higher than the specificity of RBPT. Conclusions: The investigation proved the potential usefulness of LFA for field diagnosis of brucellosis in the regions where laboratory facilities are limited.

Abstract
Trypanosomosis or surra is caused by the haemoflagellate parasite, Trypanosoma evansi and is an important disease of animals, including domestic and wild herbivores and carnivores, in tropical countries. The invariant surface glycoproteins (ISGs) are blood stream stage specific and are uniformly distributed over the entire surface of the trypanosomes. In the present study, the extracellular domain (ED) region of ISG-75 from T. evansi, consisting of 1320 nt, encoding a polypeptide of 440 amino acids, has been heterologously expressed in Escherichia coli. Further, the immunoreactivity of recombinant ISG-75 (rISG-75) was characterized in immunoblot and ELISA using T. evansi hyper immune sera raised in experimental animals. The protein was found immunoreactive when compared with a panel of antigens (VSG RoTat 1.2 and whole cell lysate) using bovine serum samples from field. The diagnostic potential of rISG-75 was evaluated in ELISA with large number of bovine field serum samples. The optimum sensitivity and specificity were 98.47 and 99.1, respectively. The present finding showed that the expressed protein has potential use in the serodiagnosis of trypanosomosis.

Abstract
Trypanosoma evansi, a haemoflagellate, causes "surra" an important chronic wasting disease of a wide range of wild and domestic herbivorous and carnivorous animals including cattle, buffaloes, camels, horses, etc. The untreated recovered animal can act as a carrier without exhibiting the disease symptoms and can be a source of infection to healthy animals. The diagnosis and subsequent treatment of the carrier animals is helpful to curb the disease. As the parasitaemia in carrier animals is very scanty, the conventional blood smear examination, which is widely practiced in the field, cannot detect such condition. For this purpose improved diagnostics are very much useful for mass sero-screening test such as ELISA. In the present study, the VSG of T. evansi was expressed in prokaryotic system (E. coli) and thereafter its immunoreactivity has been evaluated in immuno blot and enzyme immuno assay. The expressed protein showed 95.6% sensitivity, 98.0% specificity and 0.93 Cohen's kappa value, when compared with standard antigens. The developed antigen has also been validated with field serum samples from bovine, camel and horse collected from different states of India. The data showed that the developed recombinant antigen can be a diagnostic tool to detect carrier animals as well as control of the disease.

Abstract
Peste des petits ruminants (PPR) is an acute, highly contagious, world organization for animal health (OIE) notifiable and economically important transboundary viral disease of sheep and goats associated with high morbidity and mortality and caused by PPR virus. PPR is considered as one of the main constraints in augmenting the productivity of small ruminants in developing countries and particularly severely affects poor farmer's economy. The disease is clinically manifested by pyrexia, oculo-nasal discharges, necrotizing and erosive stomatitis, gastroenteritis, diarrhoea and bronchopneumonia. The disease can be diagnosed from its clinical signs, pathological lesions, and specific detection of virus antigen/antibodies/genome in the clinical samples by various serological tests and molecular assays. PPR is the one of the priority animal diseases whose control is considered important for poverty alleviation in enzootic countries. Availability of effective and safe live attenuated cell culture PPR vaccines and diagnostics have boosted the recently launched centrally sponsored control programme in India and also in other countries. This review article primarily focus on the current scenario of PPR diagnosis and its control programme with advancement of research areas that have taken place in the recent years with future perspectives.

Abstract
The present study describes the prevalence of Peste-des-petits-ruminant virus (PPRV) antibodies in cattle, buffaloes, sheep and goats carried out during the period 2011 using the serum samples randomly collected from different villages of five states of India. A total of 1,498 serum samples [n = 605 (cattle); n = 432 (buffaloes); n = 173 (sheep); n = 288 (goats)] were collected from 52 districts in five states (Andhra Pradesh, Gujarat, Jammu and Kashmir, Maharashtra and Rajasthan) of India and were screened for PPRV-specific antibodies by using PPR monoclonal antibody-based competitive ELISA kit. Analysis of 1,498 samples indicates that an overall seroprevalence of 21.83 % with 11.07 % in cattle, 16.20 % in buffaloes, 45.66 % in sheep and 38.54 % in goats. This report presents the results of PPRV-specific antibodies in situations where the subclinical, inapparent or nonlethal or recovery of infection was suspected in cattle, buffaloes, sheep and goats. The presence of PPRV antibodies demonstrate that bovines are exposed to PPRV infection and it implies the importance of cattle and buffaloes as subclinical hosts for the virus besides widespread presence of the disease in sheep and goats. Further, the study showed that the prevalence of PPRV antibodies in apparently healthy livestock under natural situation, 21.83 % of the animals were protected from PPRV re-infection. This inturn help in the implementation of disease control strategies such as vaccination in that particular geographical area.

Abstract
This research was carried out at the Agriculture Research Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar, and the Cereal Crops Research Institute, Pirsabak, Nowshera, during 2009 and 2010. Half-sib families (HS) derived from the maize variety Pahari in spring crop seasons 2009 and 2010 were developed at the Cereal Crops Research Institute. All HS families were detasseled well before pollen shedding. At maturity, each family was harvested and shelled separately. During the summer crop of seasons 2009 and 2010, these HS families were evaluated in 12 x 12 and 11 x 11 partially balanced lattice square arrangements at the Khyber Pakhtunkhwa Agricultural University, Peshawar, for various flowering and yield traits, respectively. The data on days to mid-silking, anthesis, anthesis-silking interval, 100-grain weight, and grain yield were recorded. The results revealed significant differences among families for all traits in both cycles. High heritability (0.88) was observed for days to mid-silking in cycle 0 (C₀), while moderate heritability (0.42) was recorded for 100-grain weight in C₁. The selection differential was quite reasonable and varied according to the traits of interest. The observed response for grain yield in C₀ (815.74 kg/ha) was greater than the expected response (681.76 kg/ha).

Abstract
AIM To evaluate the virulence determinants and genetic diversity of Staphylococcus aureus from bovine subclinical mastitis milk. METHODS AND RESULTS PCR detection of virulence genes was performed for 173 Staph. aureus from bovine subclinical mastitis milk. Further, genetic diversity was analysed by agr and spa typing followed by pulsed field gel electrophoresis (PFGE) of selected isolates. Screening of virulence genes (n = 19) showed the adherence genes viz. fnbA, clfA, fnbB and cna in 98·8, 97·1, 68·8 and 28·3 percentage of isolates, respectively, and 80 strains (46·24%) positive for enterotoxin genes were distributed as 23 toxinotypes, of which, 5 genotypes contained a single gene and the rest comprised of multiple toxin genes. Out of agr type-1 (87·3%), 74·2 per cent belonged to the three predominant spa types. Of 27 spa types, 11 were identified for the first time. The predominant spa types were t267 (N =44), t359 (N = 42) and t6877 (N =29), which together accounts to 66·5 per cent of isolates. PFGE analysis of isolates (N = 45) covering all the spa types revealed mostly similar or closely related pulsotypes. Local emergence of spa type t6877 in herd-dependant manner was observed. spa sequence-based phylogenetic analysis suggested t267 as the ancestral clone of t359, t6877 and other spa types except two. CONCLUSION Heterogenous virulence profile of the isolates had no significant association with the genotype. High prevalence of agr group I reaffirms their association with persistent subclinical mastitis. The spa type t267 appears to be the ancestral clone endemic in the region causing subclinical mastitis. In addition, few new spa types have emerged in the geographic region. SIGNIFICANCE AND IMPACT OF STUDY Gives an insight into the genetic and evolutionary behaviour of Staph. aureus associated with bovine subclinical mastitis in India. The study would pave the way for devising effective control strategy for bovine mastitis in Indian context.

Abstract
Indications of prostate biopsy are high serum prostate specific antigen (PSA) value and or abnormal digital rectal examination (DRE) findings. Although serum PSA value of 4 ng/ml is the most commonly used threshold for recommending prostate biopsy, significant proportion of men harbor prostate cancer even when their serum PSA values are less than 4.0 ng/ml. Therefore present study was designed to determine the performance status of serum PSA in lower cut-off values. This hospital based prospective study was conducted in the Department of Urology of Bangabandhu Sheikh Mujib Medical University (BSMMU) and Comfort Nursing Home Pvt. Ltd, Dhaka from July 2009 to October 2010. Two hundred six male patients aged over 50 years having lower urinary tract symptoms (LUTS) and serum PSA more than 2.5 ng/ml were prepared for prostate biopsy. Trans rectal ultrasound (TRUS) guided biopsy was done. The test statistics used to analyze the data were descriptive statistics, sensitivity, specificity, positive and negative predictive value, ROC curve. For all analytical tests, the level of significance was set at 0.05 and p < 0.05 was considered significant. In 2.5-4 serum PSA range, 28.26% (13 out of 46) of all malignancy were found, which would be missed if we take cut off value 4. At 2.5 PSA cut-off, Sensitivity 91.3%, Specificity 14.37%, PPV 23.46%, NPV 85.18%, Efficacy 31.55%. At 4 PSA cut-off value, Sensitivity 71.73%, Specificity 46.25%, PPV 27.73%, NPV 85.05%, Efficacy 51.94%. So it can be concluded that, for early diagnosis of prostate cancer cut-off value of serum PSA of 2.5 ng/ml can be recommended as an indication for prostate biopsy.

Abstract
Malaria is a serious global health challenge, which is responsible for more than one million deaths a year. Malarial infection is more prevalent in developing countries including Pakistan. Significant efforts have been made to control malaria; however, due to socio-environmental factors, it remains a frequent problem in Quetta. The present study was undertaken to determine the malarial incidence, species prevalence, and its demographic evaluation in human population of Quetta, Pakistan. A total of 1831 subjects, comprising 1072 male and 759 female presenting symptoms of malaria, were included in this study. Blood samples from clinically suspected individuals were subjected to the standard immunochromatographic and malaria parasite smear analysis for malaria diagnosis. Out of 1831 subjects, 338 (18.45%) patients were positive for malarial parasite while the species prevalence was found as 276 (81.66%) and 62 (18.34%) for Plasmodium vivax, and Plasmodium falciparum, respectively. Furthermore, seasonal variations gradual increase in the prevalence rate. The age group of 21-30 years (30.47%) was found more prone to malaria. The suspected malaria cases were found more frequent in rural (72.1%) as compared to urban (27.9%). In addition, the malaria burden was high in urban area (22.89%) population as compared to the rural area (16.74%) population. It was observed that the highest disease occurrence was caused by P. vivax, which reflects a serious threat for public health. The current findings will be helpful to plan effective strategies to prevent and control malaria in this area.

Abstract
The objectives of this study were to determine and compare the correlation of intravesical prostatic protrusion (IPP) and prostate volume (PV) with bladder outlet obstruction (BOO). This study was conducted in the department of urology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, between July 2009 to September 2010. Fifty benign prostatic hyperplasia (BPH) patients were included in the study. Their evaluation consisted of history along with International Prostate Symptoms Score (IPSS), digital rectal examination (DRE), transabdominal ultrasonography to measure prostate volume, intravesical prostatic protrusion & post voidal residual (PVR) urine and pressure-flow studies to detect bladder outflow obstruction (BOO). Statistical analysis included Unpaired t test, Chisquare test and Spearmans Rank correlation test. Receiver Operator Characteristic (ROC) curves were used to compare the correlation of PV and IPP with BOO. Mean prostate volume was significantly larger in bladder outlet obstructed patients (P<0.05). Mean IPP was significantly greater in obstructed patients (P<0.001). Area under ROC curve was 0.700 for PV and 0.821 for IPP. Prostate volume & intravesical prostatic protrusion measured through transabdominal ultrasonography are noninvasive and accessible method that significantly correlates with bladder outlet obstruction in patients with benign prostatic hyperplasia and the correlation of IPP is much more stronger than that of prostate volume. Introduction Benign prostatic hyperplasia (BPH) is one of the most common diseases in elderly men. The prevalence of histological BPH increases with age and appears in approximately 40% of men aged 50- 60 years and in approximately 90% of men aged more than 80 years1. Benign prostatic hyperplasia may lead to prostatic enlargement, bladder outlet obstruction (BOO) and lower urinary tract symptoms (LUTS). But the symptoms and obstruction do not entirely depend on prostates size. In contrast, intravesical prostatic protrusion (IPP) has been found to correlate with BOO2. IPP is a morphological change due to overgrowth of prostatic median and lateral lobes into the bladder and may lead to diskinetic movement of bladder during voiding. This IPP would cause more obstruction than if there were no protrusion and just enlargement of lateral lobes, as the strong bladder contraction could force open a channel between the lobes3. Several studies have previously demonstrated that the ultrasonographic measurement of IPP is able to detect BOO in BPH patients quickly and non-invasively4. This study was designed to diagnose BOO through non-invasive methods and aimed to define the correlationDOI: http://dx.doi.org/10.3329/bmrcb.v38i1.10446 Bangladesh Med Res Counc Bull 2012; 38: 14-17

Abstract
Jatropha curcas L. (Euphorbiaceae) has acquired a great importance as a renewable source of energy with a number of environmental benefits. Very few attempts were made to understand the extent of genetic diversity of J. curcas germplasm. In the present study, efforts were made to analyze the genetic diversity among the elite germplasms of J. curcas, selected on the basis of their performance in field using random amplified polymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP) and simple sequence repeats (SSR). The plants were selected on the basis of height, canopy circumference, number of seeds per fruit, weight of 100 seeds, seed yield in grams per plant and oil content. Out of 250 RAPD (with 26 primers), 822 AFLP (with 17 primers) and 19 SSR band classes, 141, 346 and 7 were found to be polymorphic, respectively. The percentage polymorphism among the selected germplasms using RAPD, AFLP and SSR was found to be 56.43, 57.9, and 36.84, respectively. The Jaccard's similarity coefficient was found 0.91, 0.90 and 0.91 through RAPD, AFLP and SSR marker systems, respectively. Principle component analysis (PCA) and dendrogarm analysis of genetic relationship among the germplasm using RAPD, AFLP and SSR data showed a good correlation for individual markers. The germplasm JCC-11, 12, 13, 14 and 15 whose yield found to be high were clustered together in dendrogram and PCA analysis though JCC11 is geographically distinct from others. In overall analysis JCC6 (in RAPD), JCC8 (in AFLP) and JCC 6 and JCC10 (in SSR) were found genetically diverse. Characterization of geographically distinct and genetically diverse germplasms with varied yield characters is an important step in marker assisted selection (MAS) and it can be useful for breeding programs and QTL mapping.

Abstract
The aim of this study was to evaluate the safety and efficacy of the supracostal access for percutaneous nephrolithotomy (PCNL). Between July 2007 and June 2010, 122 patients underwent PCNL, of whom 28 (23%) had supracostal access. All procedures were performed in a single sitting under general anesthesia. The data were analysed for indications, stone clearance rates and the complications associated with supracostal puncture. The indications for a supracostal access were staghorn stones (50%), pelvis stones (28.5%), calyceal stones in high-lying kidney (18%) and upper ureter/ureteric stones (3.5%). All tracts were made in the 11th intercostal space. Single tract access was used in 22 cases (78%), but 6 (22%) required a second tract. Additional punctures were required mainly for staghorn stones (4 out of 14). Overall, 82% of the patients were rendered stone free or had clinically insignificant residual stones with PCNL monotherapy, and this increased to 96% with secondary procedures. In patients with staghorn stones, they were completely cleared in 78%. Overall complication rate was 28% and included hydrothorax in 3 (10%) patients, which required insertion of a chest tube. One (3.5%) patient developed haemothorax secondary to injury of the intercostal artery, pelvic perforation in 1 (3.5%), perinephric collection in 1 (3.5%), infection/sepsis in 2 (7%). Except those patients who had complication, all other patient recovered uneventfully. Postoperative hospital stay ranged from 2 to 9 days. In conclusion, supracostal access gives high clearance rate with acceptable complications and should not be avoided for fear of chest complications.

Abstract
The pygmy hog is a representative of the smallest and rarest wild species of known living Suidae. This paper reports the investigation of haemorrhagic enteritis encountered amongst the pygmy hogs at the Research and Breeding Centre of the Pygmy Hog Conservation Programme, Guwahati, Assam, India. Three out of 68 pygmy hogs died of enteric infection. Post-mortem examination and bacteriological investigation of two out of the three animals that died revealed clostridial infection. The isolates harboured two plasmids of molecular weight 42.8 kilobases (kb) and 51.9 kb. Clostridium perfringens Type A positive for the beta2 toxin (cpb2) gene was detected by polymerase chain reaction. Sequence analysis of the partial alpha toxin (cpa) gene showed 98% to 100% homology with isolates from different geographical locations.

Abstract
The assessment of Citrus tristeza virus incidence in mandarin of Sikkim, involving sampling techniques, was estimated by DAS-ELISA. Mandarin orchards had high CTV incidence (46.32%), however, differential prevalence with regard to age of plant and location was observed. The CTV prevalence was relatively high in older orchards (51.01%) than that of younger ones (40.80%). Under all the plant age groups, south district had the highest CTV incidence (52.50%) and east district had the lowest (37.71%). The spatial distribution of CTV in plants indicates high concentration in twig followed by leaf tissue, however, stem had relatively less concentration. High aphid infestation was observed in all mandarin growing groves with the maximum in south district and minimum in east district. Taxoptera citricida was the predominating aphid species followed by T. aurantii, however, Aphis spp population was significantly less. Aphid infestation and CTV prevalence were positively and significantly correlated.

Abstract
An Indian elephant (Elephas maximus) which died of acute fatal myonecrosis was examined to determine the aetiology of the infection. The causative organism was identified as Clostridium perfringens type A. Out of five genes encoding for major toxins (cpa, cpb, etx, iA, and cpe genes) the isolate was found to harbour the cpa gene only, as tested by multiplex polymerase chain reaction. It flanks a 324 base pair segment in the cpa gene, indicating the presence of the alpha toxin gene. The organism was sensitive to amikacin, ampicillin, enrofloxacin, gentamicin and norfloxacin but was resistant to bacitracin, oxytetracycline and tetracycline. The acute malignant nature of the myonecrosis and presence of the alpha toxin gene in the isolate suggested that the myonecrosis, although clinically resembling that caused by C. chauvoei in cases of black quarter, was caused by C. perfringens type A.

Abstract
Aims of the present study were to find out the histological pattern of atypically presenting nephrotic syndrome children and their response with oral corticosteroid therapy. This prospective study was carried out in the Paediatric Nephrology unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, for a period of two years, from September 2001 to September 2003. Forty children with nephrotic syndrome with atypical presentations such as gross haematuria, renal impairment, hypertension and hypocomplementaemia were enrolled for the study. For each patient proper investigations were done to screen out infection and necessary treatment was given accordingly. Renal biopsy was done in all cases after treating infection and controlling hypertension and specimen were evaluated by light and immunofluorescence microscopy. All the patients were treated with oral prenisolone 60 mg/m2/day for 4 weeks and response were observed by heat coagulation test. In present study it was observed that mean age of presentation was 8.73+/-4.36 years. Hypertension, gross haematuria, impaired renal function and hypo-complementaemia were observed in 50%, 45%, 19% and 15% cases respectively. When histopathologies were considered, 90% cases had other than minimal change disease (MCD) and Mesangial proliferative glomerulonephritis (MesPGN) was the most common histopathology (47.5%). Regarding steroid therapy only 43.2% patients were responsive to oral prednisolone therapy within 28 days. Atypically presented nephrotic syndrome usually manifested with higher age of onset, gross haematuria, hypertension, renal insufficiency and hypocomplementaemia. Mesangial proliferative glomerulonephritis was the predominant histological type. The majority (56.8%) of these atypically presented nephrotic syndromes were resistant to steroid therapy.

Abstract
A retrospective study of 74 children with Urinary Tract Infection (UTI) were evaluated for the prevalence of vesicoureteric reflux (VUR) at a tertiary hospital in Dhaka, Bangladesh from 2003 to 2006. There were 45 (60%) girls and 29 (40%) boys; 58 (78%) were at an average age between 1-5 years, 11 (15%) were between 0-1 year and five (7%) were more than 5 years of age. All patients were documented to have UTI by history and laboratory investigations. There were 27 (36%) patients who had acute pyelonephritis at the initial clinical presentation and fourty seven (64%) patients had recurrent UTI. Thirty two (43%) patients had vesicoureteric reflux; fifteen (47%) had it bilaterally (VUR); and 13 (41%) had renal scarring. Five (7%) patients who had renal scarring were with- out reflux. Twenty three (72%) of the VUR patients had mild to moderate reflux (grade 1-3) and nine (28%) had severe reflux (grade 4-5). The age of the patients with VUR was below one year in 13 (40%), between 1 and 5 years in 17 (53%) and between 6 and 12 years 2 (7%) patients. There were 9 (33%) patients with acute pyelonephritis who had reflux. Follow-up of the VUR patients showed that reflux disappeared with out surgical intervention in 14 (44%), improved in three (9%) to lower grade and worsened in two (6%) to higher grade. Five (16%) patients underwent ureteral re-implantation; all the patient of VUR had recurrent UTI and were more than one year of age. While on chemoprophylaxis, two of the reimplanted patients developed break-through UTI. None of the study patients developed new scars, hypertension or renal failure during follow-up; the duration of follow-up was from 6 months to 3 years. Children with UTI below 6 years of age have high incidence of reflux and scarring with specially in patients with acute pyelonephritis.

Abstract
Cytomegalovirus (CMV) infection is a very rare infection in children as well as in infancy. In CMV infection extra renal manifestations in central nervous system (CNS), eyes and hematological are prominent and common than renal manifestation. We are describing two case reports one at the age of 5 months and another at one month with features of both extra renal and renal manifestations of nephritic syndrome. Our first case presented with predominant features of CNS manifestations like convulsion and spastic monoplegia, sensory type of deafness and absence of light reflexes along with nephritic features. Deafness and absence of light reflex were confirmed by audiometric and ophthalmological examination and brain atrophy was confirmed by CT scan. Our second case had features of hypothyroidism along with nephritic features. Hypothyroid status was confirmed by elevated serum TSH level and reduced T4 level. In both cases nephritic features were confirmed at bed site urine examination by heat coagulation test and other relevant investigations. CMV infection was confirmed in both cases by detecting anti CMV IgM by ELISA method. Both patients were clinically improved with intravenous gangcyclovir therapy. In these two cases reports, clinical, serological and therapeutic observation established the causal relationship between the CMV infection and nephrotic syndrome.

Abstract
Leptospirosis is one of the important zoonoses of man and animals. In recent years, it has increasingly been reported from different parts of the world including India. Sera from 536 individuals with pyrexia of unknown origin (PUO) belonging to different age group, sex and occupation and having varying levels of exposure to animals, forest and flood were examined for the presence of antibodies to pathogenic Leptospira by commercially available kit. Overall 22.57% individuals with PUO were found to be positive for leptospirosis with 27.93% among male and 11.79% among female patients. This difference among..genders was statistically significant. The seropositivity was higher among patients in the age groups of 21-30 years followed by 31-40 and 41-50 years. Seropositivity was higher among individuals having contact with animals, working in forest and flood affected areas.

Abstract
Stomatal conductance is an important heat avoidance mechanism and its association with higher yield and heat resistance has been established in Pima cotton. Experiments were carried out on upland cotton under heat-stressed and non-stressed greenhouse and field regimes, to understand the impact of heat-stressed and non-stressed environments on the genetic and combining ability variations for stomatal conductance. The experimental material comprised 8 upland cotton cultivars and their 15 F
1
cross combinations obtained in a line × tester mating arrangement. The results showed high genetic variability for stomatal conductance in a single environment, but low genetic variability across environments, due to the higher magnitude of the environmental interaction, especially that caused by temperature regimes. The interaction effect of temperature regimes also substantially modified general and specific combining ability variations for stomatal conductance. The relative contributions of general and specific combining abilities to total phenotypic variation for stomatal conductance also underwent a great change across field temperature regimes. The non-stressed regime favoured the expression of genes causing the additive type of genetic variability. The heat-stressed field regime, however, favoured the expression of both additive and non-additive types of genetic variation for stomatal conductance in upland cotton. Recurrent selection for the accumulation of favourable genes for general combining ability under non-stressed conditions was suggested for improving stomatal conductance in applied cotton breeding programmes.

Abstract
Toxoplasmosis is one of the important zoonoses of man and has been known to cause serious problems particularly in females. A study on seroprevalence of toxoplasmosis was undertaken amongst the human population in Assam to determine the level of exposure of the population to the infection by using commercial ELISA kits. Of the 241 sera belonging to different age groups, sex and religion and having varying levels of exposure to the animals examined, 23 (9.54%) were positive for toxoplasmosis. No significant difference in the prevalence amongst males and females was observed. Some occupational groups like veterinarians, pet keepers and farmers were found to infect more frequently. Although the overall prevalence rate of toxoplasmosis was relatively low, higher prevalence rate of toxoplasmosis amongst the exposed groups warrants due care by these groups when they are handling the animals.

Abstract
The study was done to see the relationship of recurrent laryngeal nerves with corresponding inferior thyroid artery with the aim to increase the knowledge regarding variational anatomy in our population. Sixty samples were collected as block dissection of thyroid gland along with the surrounding structures containing the supplying vessels and adjacent nerves from 48 male and 12 female cadavers of different age groups and fixed in 10% formol-saline solution. Fine dissections were carried out to study the toporgaphic relationship of recurrent laryngeal nerves with corresponding inferior thyroid artery. The findings were compared between different age groups and also with the findings of western researchers. In this study, in majority of the cases the recurrent laryngeal nerves were found in their usual location that is posterior to the terminal branches of inferior thyroid artery on the left side and anterior to that artery on the right side. It was important to note that, on both sides recurrent laryngeal nerves were also frequently found to pass in between the terminal branches of inferior thyroid artery.

Abstract
BACKGROUND & OBJECTIVE Salmonella induced enteritis is a complex phenomenon involving a number of pathogenic factors. Type III secretions play a central role in the development of Salmonella induced enteritis. One such Type III secretion protein is Salmonella outer proteinB (SopB). Reports on the prevalence of this gene among different serovars of Salmonella of Indian origin appears to be lacking. The present investigation reports on the prevalence of sopB gene and its phenotypic expression (SopB protein) among different serovars of Salmonella enterica isolated from man and animals. METHODS A total of 50 isolates of S. enterica belonging to 11 serovars isolated from cases of enteric infection in man, birds and animals were tested for the presence of sopB gene by polymerase chain reaction (PCR) using its specific primers. The in vitro phenotypic expression of SopB protein was detected by dot-ELISA using anti-SopB serum. RESULTS All the 50 isolates of S. enterica belonging to 11 were found to carry sopB gene irrespective of their serovars like Typhimurium, Enteritidis, Gallinarum, Choleraesuis, Virchow, etc., and source of isolation. Of these, 41 isolates were found to express sopB gene phenotypically as detected by dot- ELISA using anti-SopB serum. Of the different serovars, all but Gallinarum expressed Sop B protein phenotypically in vitro. INTERPRETATION & CONCLUSION Our findings indicated that sopB gene was wildely distributed and conserved among Salmonella irrespective of their serovars and source of isolation. Further work need to be done to study the factors associated with the phenotypic expression of this gene.

Abstract
BACKGROUND & OBJECTIVE The non-tuberculous mycobacteria (NTM) have emerged as important opportunistic pathogens of human beings in the recent years. The NTM are rapid growing mycobacteria (RGM), which include Mycobacterium fortuitum and M. chelonae and grouped as M. fortuitum-chelonae complex. Though there are reports on isolation of NTM from various parts of India, information on its occurrence in northeastern India is lacking. We therefore undertook this preliminary investigation to report on the occurrence of NTM-associated with non-healing postoperative wound infections that did not respond to antibiotics used for pyogenic infections and having sterile routine aerobic cultures in patients from northeastern part of India. METHODS Pus/discharge from 25 patients with delayed onset of post-operative wound infections not responding to antibiotics used for pyogenic infections were collected and examined for isolation and identification of the causative agents. RESULTS Of the 25 pus/discharge specimens examined, 20 revealed growth of non-tuberculous Mycobacterium spp. All the isolates were identified as M. fortuitum-chelonae complex. Of these only 10 samples revealed acid-fast bacilli (AFB) on direct examination of Ziehl-Neelsen stained smears from the specimens. All cases where direct smear was positive for AFB were also positive for Mycobacterium culture. INTERPRETATION & CONCLUSION The results of the present study indicated that non-tuberculous mycobacterial post-operative wound infection was fairly common in northeastern India. Thus, mycobacterial infections should be considered in wounds that show delayed healing and do not respond to antibiotics used for acute pyogenic infections. Further, 80 per cent of the specimens yielded the growth of AFB in cultures as against only 40 per cent positive in the ZN stained direct smears. This indicates the possibility of missing a mycobacterial wound infection if only direct smears are taken for diagnosis.

Abstract
The pigmy hog (Sus salvanius) is the smallest and the rarest wild suid in the world. This species is on the verge of extinction and the World Conservation Union has rated it among the most endangered of all mammals. This paper reports the investigation into an outbreak of salmonellosis among captive pigmy hogs at the Research and Breeding Centre of the pigmy hog conservation programme, Guwahati, Assam, India. Of 75 pigmy hogs (38 males and 37 females) maintained at the Centre, seven (9.3%) died within five days. The causative organism associated with the outbreak was identified as Salmonella Typhimurium (syn. S. enterica serovar Typhimurium). All the isolates of S. Typhimurium belonged to phage type DT193. The isolates harboured multiple plasmids. Five isolates harboured four (65.0 MDa, 4.2 MDa, 3.0 MDa, 1.3 MDa), while two isolates carried three plasmids (65.0 MDa, 4.2 MDa, 3.0 MDa). All strains showed resistance to amikacin, ampicillin, streptomycin and sulfamerazin; five strains were resistant to oxytetracycline and trimethoprim. All the strains were sensitive to chloramphenicol, ciprofloxacin, enrofloxacin and gentamicin. All seven isolates of S. Typhimurium were found to harbour stn, sopB and pefA genes. However, none of them was found to carry sefC and sopE genes.

Abstract
BACKGROUND AND OBJECTIVE Salmonella is an important zoonotic pathogen and its prevalence in the animals acts as a continuous threat to man. The present study was carried out to report the isolation along with the serotypes, phage types and antibiogram pattern of Salmonella among man, livestock and poultry in the northeastern India. METHODS A total of 654 samples from diarrhoeic livestock and humans were processed for the isolation of Salmonella. All the isolates were subjected to antibiogram studies against 15 antimicrobials. Representative isolates of S. Typhimurium and S. Enteritidis were phage typed. RESULTS Ninety five isolates of Salmonella enterica belonging to 5 serotypes- S. Typhimurium, S. Enteritidis, S. Gallinarum, S. Paratyphi B and S. Bareilly were obtained with an overall prevalence rate of 14.40 per cent. S. Typhimurium isolates were distributed among four phages- DT003, DT004, DT096 and DT193 and all the S. Enteritidis isolates belonged to a single phage type, PT13a/7. Interspecies sharing of the phages was observed. Norfloxacin, enrofloxacin, gentamycin and ciprofloxacin were most effective, whereas, doxycycline, ampicillin, amoxycillin and tetracycline were relatively less effective. INTERPRETATION AND CONCLUSION Our findings showed that three of the five serovars as well as some of the phage types of these serovars were shared by animals and humans indicating the zoonotic potential of the organism. Thus, it is imperative that salmonellosis control measures adopted for humans should give adequate importance to its control in the animals particularly their products.

Abstract
Forty five (24 male & 21 female) moderate to severe degree of predialysis CRF patients were prospectively studied over a period of 6 months (July- December, 2004) to see the effect of Recombinant Human Erythropoietin (rHuEpo/EPO) therapy on renal anaemia, progression of renal excretory function & quality of life at 3 and 6 months intervals from the starting of EPO therapy. Mean +/- SD age of the patients was 56 +/- 12 (30-77 yrs) and causes of CRF were Diabetic Nephropathy (DN)=15 (33%), Chronic Glomerulonephritis (CGN) =14(31%), Hypertension (HTN)=11(21%), Chronic Pyelonephritis (CPN)=03 (6.5%) and Obstructive Uropathy (OU)=02 (4.5%). Doses of rHuEpo was 80-100 IU/k week subcutaneously (SC) until the target Hb 11gm% & Hct 30% were achieved; there after the dose was titrated as appropriate. Serum Iron & Ferritin levels were also kept within normal reference level by iron therapy during the study period. Mean +/- SD base line (before starting EPO therapy) level of haemoblobin were 8.4 +/- 0.81(gm%), Hct 27.86 +/- 1.6 (%), blood urea 21.72 +/- 10.5 (mmol/L), S. creatinine 431.93 +/- 228.79 (mmol/L) & Ccr. 21.25 +/- 10 mum respectively. The results showed that significant improvement of haemoglobin level occurred (gm%) from 8.4 +/- 0.81 (gm%) to 9.51 +/- 1.02 (p<0.001) at 3 months and 8.4 +/- 0.81 to 11.10 +/- 1.4, (p<0.001) at 6 months interval. Haematocrit (Hct%) value also significantly increased from 27.86 +/- 1.5 to 30.57 +/- 3.62, (p<0.001) at 3 months and 27.86 +/- 1.5 to 32.81 +/- 3.92 (p<0.001) at 6 months of EPO therapy. Mean blood urea and S. creatinine levels decreased from base line level during the study period but did not show any statistical significance. There was no significant side-effects like uncontrolled hypertension, seizure or hyperviscosity syndrome in any of the study population. The quality of life in terms of improvement of physical ability and sense of well being were also improved in all the study patients. In conclusion, this study showed that the effect of rHuEpo therapy is beneficial for the correction of renal anaemia, can delay the progression of renal failure and improvement of overall quality of life in predialysis CRF patients.

Abstract
Salmonella pathogenesis is a complex phenomenon and a Type III secretion system plays a central role in the development of Salmonella-induced enteritis. One such Type III secretion protein is Salmonella outer protein E (SopE). Prevalence of sopE gene and its phenotypic expression (SopE protein) among different serovars of Salmonella enterica isolated from man and animals were investigated. Of 305 strains of S. enterica belonging to 11 serovars tested for the presence of sopE, 130 strains belonging to three serovars viz., Enteritidis, Gallinarum and Virchow were found to carry sopE gene irrespective of their source of isolation when tested by PCR amplification technique using its specific primers. Of these 130 strains, 112 strains were found to express SopE protein phenotypically as detected by Dot-ELISA using SopE antibody. Among the different serovars tested only serovars Gallinarum, Enteritidis and Virchow expressed SopE protein phenotypically in vitro. Role of SopE protein in pathogenesis of salmonellosis has been discussed.

Abstract
Between 1996 and 2002, we treated 60 patients (65 hips) by hip resurfacing. The notes and radiographs of these cases were studied retrospectively and the modalities of failure identified. At a mean follow-up of 51 months, 14 of these cases (22%) required revision surgery. One patient had died from unrelated causes and one was lost to follow-up. At the time of primary surgery, the mean age of the patients in our series was 55 years. The commonest mechanism of failure in our series was fractured neck of femur (six cases). Four of these occurred in females over the age of 60. None of the fractured necks of femur were associated with trauma. There were four cases of loose acetabular components and one case of progressive AVN (avascular necrosis). Two patients required revision surgery for ongoing hip pain and one required a twostage revision for early deep infection. (Hip International 2005; 15: 155-8).

Abstract
To study the circumference of atrioventricular orifices of the Bangladeshi adult people, fifty postmortem hearts were collected, fixed in 10% formol saline and examined. In the present paper, the findings were compared between male and female values and also with the findings of Western and Bangladeshi researchers. Among fifty hearts, thirty-six hearts were collected from male and fourteen hearts were collected from female cadavers. The findings suggest that the atrioventricular orifices of the hearts examined were lower in circumferences as compared to those described in the available texts. The female values were slightly lower than the male values but on statistical analyses, they showed no significant difference (P > 0.05).

Abstract
Studies conducted on the seroprevalence of brucellosis in 98 mithuns maintained at the National Research Centre on Mithun, Nagaland, India revealed that the number of animals found positive for brucellosis in avidin-biotin enzyme-linked-immunosorbent assay, standard tube-agglutination test and Rose-Bengal plate test were 34, 20 and 11%, respectively. Highest prevalence of brucellosis was observed in the Mizoram mithun strain. The relative sensitivity and specificity of the standard tube-agglutination test were 61 and 100%, respectively; the corresponding values of the Rose-Bengal plate test were 33 and 100%, respectively.
