Abstract
Bovine Ephemeral Fever Virus (BEFV) is a non-contagious virus that commonly infects cattle and water buffalo, reduces milk productivity, decreases the quality of beef, and causes an adverse economic impact on the global livestock industry. However, the evolution of BEFV is unclear, and uncertainty exists regarding its global geodynamics. Consequently, this study aims to comprehend the pattern of viral evolution and gene expression in the BEFV genes G, M, N, and P, including synonymous codons. Additionally, we performed recombination analyses, which exclusively detected recombination signals in the G- and P-genes. Subsequently, a phylogenetic tree was constructed to validate and support these findings. The codon usage bias results showed that the BEFV-selected genes were influenced by both natural and mutation pressure. Furthermore, nucleotide A is more abundant in all the selected genes. The eNC values, ranging from 42.99 to 47.10, revealed the presence of moderate codon usage bias, where gene P exhibited the highest and gene G had the lowest codon usage bias. The neutrality and PR-2 plots, specified codon usage patterns of the genes, are also being shaped by strong selectional pressure. This comprehensive analysis of BEFV genes (G, M, N, and P) sheds light on the molecular evolutionary patterns, co-adaptation, and different genes expression in diverse regions, facilitating the development of preventative programs and insights into viral pathogenesis and vaccine design.Communicated by Ramaswamy H. Sarma.

Abstract
Purpose COVID-19-associated rhino-orbital-cerebral mucormycosis (ROCM) has reached epidemic proportion during India's second wave of COVID-19 pandemic, with several risk factors being implicated in its pathogenesis. This study aimed to determine the patient demographics, risk factors including comorbidities, and medications used to treat COVID-19, presenting symptoms and signs, and the outcome of management. Methods This was a retrospective, observational study of patients with COVID-19-associated ROCM managed or co-managed by ophthalmologists in India from January 1, 2020 to May 26, 2021. Results Of the 2826 patients, the states of Gujarat (22%) and Maharashtra (21%) reported the highest number of ROCM. The mean age of patients was 51.9 years with a male preponderance (71%). While 57% of the patients needed oxygen support for COVID-19 infection, 87% of the patients were treated with corticosteroids, (21% for > 10 days). Diabetes mellitus (DM) was present in 78% of all patients. Most of the cases showed onset of symptoms of ROCM between day 10 and day 15 from the diagnosis of COVID-19, 56% developed within 14 days after COVID-19 diagnosis, while 44% had delayed onset beyond 14 days. Orbit was involved in 72% of patients, with stage 3c forming the bulk (27%). Overall treatment included intravenous amphotericin B in 73%, functional endoscopic sinus surgery (FESS)/paranasal sinus (PNS) debridement in 56%, orbital exenteration in 15%, and both FESS/PNS debridement and orbital exenteration in 17%. Intraorbital injection of amphotericin B was administered in 22%. At final follow-up, mortality was 14%. Disease stage >3b had poorer prognosis. Paranasal sinus debridement and orbital exenteration reduced the mortality rate from 52% to 39% in patients with stage 4 disease with intracranial extension (p < 0.05). Conclusion : Corticosteroids and DM are the most important predisposing factors in the development of COVID-19-associated ROCM. COVID-19 patients must be followed up beyond recovery. Awareness of red flag symptoms and signs, high index of clinical suspicion, prompt diagnosis, and early initiation of treatment with amphotericin B, aggressive surgical debridement of the PNS, and orbital exenteration, where indicated, are essential for successful outcome.

Abstract
Animal disease surveillance encompasses systematic collection of long-term data on disease events, risk factors and other relevant parameters followed by analyzing the same with reference to temporal and spatial characteristics to arrive at a conclusion so that necessary preventive measures can be taken. In India, the animal disease surveillance is done through National Animal Disease Reporting System, which is a web-based information technology system for disease reporting from States and Union Territories with the aim to record, monitor livestock disease situation and to initiate the preventive and curative action in a swift manner during disease emergencies. National Animal Disease Referral Expert System is a dynamic geographic information system and remote sensing-enabled expert system that captures an incidence of 13 economically important livestock diseases from all over the country and also provides livestock disease forecasting. The laboratories under State and Central governments, several research institutes under the Indian Council of Agricultural Research and veterinary colleges are involved in livestock disease diagnosis including zoonotic diseases. An integrated surveillance system is necessary for early detection of emerging/zoonotic diseases in humans. This review provides information on disease reporting and surveillance systems in animal health sector and the need for One Health approach to improve and strengthen the zoonotic disease surveillance system in India.

Abstract
Fluorescence quenching and preferential solvation of a coumarin derivative, namely 3-[2-oxo-2-(2-oxo-2H-chromen-3-yl)-ethylidene]-1,3-dihydro-indol-2-one (3OCE), with aniline used as a quencher in solvent mixtures of acetonitrile (AN) and 1,4-dioxane (DX) was carried out at steady state. Suppan's theory of dielectric enrichment was used to understand the nonideality and dielectric enrichment in AN-DX solvent mixtures. The effect of viscosity and dielectric constant variation at room temperature were analyzed. Quenching was characterized using Stern-Volmer plots with an upward curvature. It was found that 3OCE underwent combined static and dynamic quenching that was evident from the quenching rate parameters.

Abstract
A covalently cross-linked injectable hybrid hydrogel, namely, alginate/poly(amidoamine) (PAMAM), with the objective of cell delivery was innovatively designed and synthesized using tetra-amino-functional PAMAM dendrimer as the cross-linker. With the increase in percentage of PAMAM cross-linker, the pore size and swelling ratio of hydrogels were in the range of 57 ± 18 μm to 88 ± 25 μm and 110 ± 16 to 157 ± 20, respectively. The study of attachment and proliferation of MC3T3-E1 pre-osteoblasts using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay through indirect and direct contact methods indicated a continuous increase in metabolically active live cells with time, implying non-cytotoxicity of the synthesized hydrogel. The live–dead assay showed >95% of live cells for alginate/PAMAM hydrogels, suggesting viability of the encapsulated cells. When the percentage of PAMAM cross-linker in alginate/PAMAM hydrogel was increased from 5 to 25, the percentage degradation rate decreased from 1.1 to 0.29%/day. Given that the poly(ethylene glycol) is commonly used cross-linker for hydrogel syntheses, we compared the behavior with poly(ethylene glycol). The incorporation of poly(ethylene glycol) in alginate/PAMAM hydrogel reduced the activity of MC3T3-E1 cells and their viability compared to the alginate/PAMAM hydrogels. The protonation of amino groups in alginate/PAMAM injectables under physiological conditions led to the formation of cationic hydrogels. These cationic hydrogels showed enhanced cell encapsulation and attachment ability because of electrostatic interaction with negatively charged cell surface as determined by cell adhesion and extensions from scanning electron microscope and vinculin assay and ability of in situ calcium phosphate mineralization. These observations point toward the potential use as an injectable scaffold for cell delivery and tissue engineering applications.

Abstract
Aim: The aim of the study was to determine the overall prevalence of classical swine fever (CSF) in pigs in India, through a systematic review and meta-analysis of published data. Materials and Methods: Consortium for e-Resources in Agriculture, India, Google Scholar, PubMed, annual reports of All India Coordinated Research Project on Animal Disease Monitoring and Surveillance, and All India Animal Disease database of NIVEDI (NADRES) were used for searching and retrieval of CSF prevalence data (seroprevalence, virus antigen, and virus nucleic acid detection) in India using a search strategy combining keywords and related database-specific subject terms from January 2011 to December 2015 in English only. Results: A total of 22 data reports containing 6,158 samples size from 18 states of India were used for the quantitative synthesis, and overall 37% (95% confidence interval [CI]=0.24, 0.51) CSF prevalence in India was estimated. The data were classified into 4 different geographical zones of the country: 20% (95% CI=0.05, 0.55), 31% (95% CI=0.18, 0.47), 55% (95% CI=0.32, 0.76), and 34% (95% CI=0.14, 0.62). CSF prevalence was estimated in northern, eastern, western, and southern regions, respectively. Conclusion: This study indicates that overall prevalence of CSF in India is much lower than individual published reports.

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
The absorption and fluorescence spectra of newly synthesized aryl boronic acid derivative namely Phenyl boronic acid (PBA) have been recorded in various solvents of different polarities. The ground state dipole moment of PBA was obtained from quantum chemical calculations. Solvatochromic correlations were used to estimate the ground state (μg) and excited state (μe) dipole moments. The excited state dipole moments are observed to be greater than the ground state dipole moments. Further, the ground and excited state dipole moments are not parallel but subtend by an angle of 70°. The changes in dipole moment (Δμ) were calculated both from solvatochromic shift method and microscopic solvent polarity parameter (ET(N)), and the values are compared. Solvent effects on the absorption and fluorescence spectra were quantified using Reichardt's and bulk solvent polarity parameters were complemented by the results of the Kamlet-Taft treatment.

Abstract
Diagnosis of Bacille calmette-guerine (BCG) adenitis is clinical. Conventional laboratory tests do not differentiate BCG adenitis from tuberculous adenitis. We report a case of a 3-month-old healthy baby presenting with suppurative BCG adenitis. FNAC revealed AFB on ZN-Staining, later confirmed to be Mycobacterium bovis by multiplex PCR. The treatment of suppurative BCG adenitis is needle aspiration. Anti-tubercular treatment is unwarranted.

Abstract
Aim: This study was carried out to evaluate groundnut haulms (GNH) as alternate feed source by its incorporation and assessment in terms of feed intake and growth performance in the diets of broilers. Materials and Methods: A total of 240 1-day-old Cobb-400 broiler chicks were randomly assigned to four dietary treatments each with three replicates (n=60). Experimental Birds in group T1 were fed with conventional feed while birds in T2, T3, T4 were fed containing 2%, 4%, and 6% of GNH replacing maize and soyabean on iso-nitrogenous basis. Results: Feed intake increases significantly (p>0.05) with increasing level of GNH in the diets of experimental birds. Highest feed intake was recorded in T4 (6% GNH), followed by T3 (4% GNH) than T2 (2% GNH) and T1 (control). Birds fed GNH gained significantly (p<0.05) higher body weight than birds fed the control diet. Birds in T4 [6% GNH] gained highest body weight, followed by T3 (4% GNH) than T2 (2% GNH) and T1 (control). However, feed conversion ratio (FCR) remained non-significant for all treatment groups. Conclusion: On the basis of the results of this study, it is concluded that supplementation of GNH can successfully replace costly ingredients like maize and soybean meal in the diets of broiler birds up to the level of 6 percent of concentrate mixture without any harmful effects on feed intake, growth and FCR.

Abstract
This study describes development of a TaqMan probe based real time PCR assay that can detect BoHV-1 of as low as 0.001 TCID50/0.1 ml in clinical samples, its comparative evaluation with indirect ELISA and virus isolation for detection of Bovine herpes virus-1 (BoHV-1) in semen and swab clinical samples. For this study, we collected samples from 212 animals (cattle and buffaloes) comprising 91 bulls and 121 females. Avidin-biotin ELISA employed on serum samples from 212 animals revealed 74 as seropositive for BoHV-1. On inoculation of semen/swabs on MDBK cell line, nine samples yielded cytopathic changes characteristic of herpes viruses. The isolates were confirmed by VNT and a conventional PCR. A real time PCR assay was standardised by designing a new set of TaqMan probe and primers targeting a 71 bp region on gB gene of the virus. The assay detected viral antigen in 21 seropositive and 14 seronegative animals, emphasizing the relevance of serology in BoHV-1 diagnosis, particularly in breeding stations. Further, real time PCR assay was 100 % sensitive and 87.19 % specific compared to virus isolation in detection of the BoHV-1 in clinical samples. The assay was validated at reputed national laboratories, with a sensitivity of ≥99 %.

Abstract
The bovine immunodeficiency virus (BIV) is a lentivirus which is known to infect cattle worldwide. Though serological and genomic evidence of BIV in cattle has been found throughout the world, isolation of the virus has been reported only from few places. Very little is known about its impact on animal health status, pathogenesis and mode of transmission. BIV is considered generally non-pathogenic and is not known to cause any serious disease in cattle. BIV is genetically and antigenically related to Jembrana disease virus (JDV), the cause of an acute disease in Bali cattle (Bos javanicus) and human immunodeficiency virus, the cause of acquired immunodeficiency syndrome in human. Therefore, it is important to monitor the presence of BIV in cattle to keep vigil over its possible evolution in its natural host to emerge as pathogenic lentivirus like JDV. Differentiation of BIV infection in cattle from the acutely pathogenic JDV is important for diagnosis of the latter. Currently, BIV is considered as a safe model for understanding the complex genome of lentiviruses. Further research on BIV is indeed needed to elucidate its possible role in animal health as well as for insight into the molecular mechanisms adopted by related lentiviruses.

Abstract
An extensive study has been carried out within the site of Bhabha Atomic Research Centre, Trombay, for examining the atmospheric dispersion of (41)Ar released from research reactors. The release rate, release height, meteorological parameters and geographical information were used to establish correlation between theoretical estimation using Gaussian plume dispersion model (GPDM) and dose/dose rate data obtained from Gammatracers (GTs). Ten monitoring locations were selected in five sectors and at different downwind distances from the release point. Analysis of dose rate data shows that the maximum dose rate (7.19 μSv h(-1)) and the total annual dose (1051 μSv) were observed at a downwind distance of 0.36 km. Average dose rates of all monitoring locations were varying from 0.03±0.02 to 0.12±0.07 μSv h(-1). The average dose rate increases at the monitoring locations placed at N to NE sectors during monsoon, and for monitoring locations placed at SW and SSE sectors during winter. The maximum dose rates, monthly and annual doses recorded by GT, have been compared with predicted values. Most of the locations show statistically significant coherence in the case of monthly dose.

Abstract
The solid state properties and dissolution behaviour of binary systems of mefloquine hydrochloride (MH) with betaCD were investigated. MH-betaCD interaction in the solution state was studied by phase solubility analysis and demonstrates the ability of 3CD to complex with MH giving AL type profile with 120.34 M-1 stability constant. The kneading method was adopted to prepare binary sytems of MH with betaCD in 1:1 molar ratio. The solid inclusion was characterized by differential scanning calorimetry, fourier transformation infrared spectroscopy and X-ray powder diffractometry. Experimental results confirmed the existence of 1:1 inclusion complex of MH with ICD. Aqueous solubility of MH was found to be enhanced by 118% for inclusion complex. The dissolution properties of binary systems were studied in simulated gastric fluid without enzyme and compared with MH alone. The inclusion complex of MH prepared with 3CD showed a dissolution rate several times faster than that of physical mixture and pure drug.

Abstract
2-thio-3-aryl quinazolin-4(3H)one (1) was synthesized by reacting anthranilic acid with thiocarbamate salts of substituted aniline and carbon disulphide, which on reflux with excess of hydrazine hydrate to form 2-hydrazino quinazolin-4(3H)one derivatives (2). The reaction of (2) with variously substituted aryl aldehydes gave the corresponding hydrazones (3). Further, the cyclization of compound (3) in acetic anhydride gave tricyclic pyrazoloquinazolinones (4). All newly synthesized compounds have been tested for their antibacterial activity against gram +ve bacteria B. substilis, S. aureus and gram –ve bacteria E. coli, P. vulgaris. The species used for antifungal activity are Aspergillus niger and Phytophora. Introduction of -OCH3, -OH and -Cl groups to the heterocyclic frame work enhanced antibacterial and antifungal activities.

Abstract
Three naturally occurring toxigenic strains (HB-36, G-50, and HB-33), one nontoxigenic strain (HB-20), and one ultraviolet light-induced toxinless mutant (G-50 Tox) of Pseudomonas phaseolicola were examined by dye-buoyant density equilibrium centrifugation for the presence of plasmid deoxyribonucleic acid. All strains contained plasmid deoxyribonucleic acid. Comparison of the plasmid deoxyribonucleic acid of different strains by agarose gel electrophoresis showed that strain G-50 harbored three plasmids, whereas the rest of the strains contained two plasmids each. Irrespective of their toxigenicity, all strains shared the large-sized first plasmid band, but differed with respect to other plasmids. Restriction endonuclease analyses of the plasmids indicated that a 22.50-megadalton plasmid was common to two of the toxigenic strains (HB-36 and G-50). However, strain HB-33, which is also toxigenic, contained a much smaller plasmid (4.23 megadaltons). It is hypothesized that this small plasmid may have arisen by a recombination event from a larger plasmid.

Abstract
Bluetongue Virus (BTV) genome segment 10 (S10)-based phylogenetic studies are important in understanding the BTV evolution. S10 gene-based phylogenetic analysis grouped six different BTV isolates (BTV serotype 1, 18 and 23) from India in subclade A1 and showed closer relationship with BT viruses from Mediterranean Basin. Indian BTV serotypes 18 and 23 formed a single cluster distinct from BTV serotype 1 isolates and were evolved from BTV from China, Indonesia and Australia. The overall S10 sequences of BTV isolates from India were largely conserved (>95.7% homology) and were distinct from other BT viruses of the world.

Abstract
In India, about 20,000 people die of rabies every year. The dog is the main reservoir and transmitter of the disease. A pilot rabies control programme was launched in five Indian federal states in February, 2007. This initiative is led by the Animal Welfare Board of India (AWBI) federating many animal welfare organizations and the Ministry of Agriculture. It aims at creating a "Rabies Free India." The programme combines parenteral vaccination of accessible owned and stray dogs, spaying/neutering followed by parenteral vaccination and oral vaccination of inaccessible dogs. The freeze-dried vaccine SAG2, including the bait casing, was registered in India following successful evaluation of vaccine-bait safety and efficacy (by survival after virulent challenge) in captive Indian stray dogs in the Bhopal High Security Animal Disease Laboratory. Furthermore, bait acceptance was tested under both experimental and field conditions.

Abstract
India is one of the countries with the highest prevalence of human rabies throughout the world. Dogs are primarily responsible for rabies transmission. Among them, stray dogs play a major role in that country. Parenteral vaccination programmes are insufficient to eliminate rabies partly due to difficulties in establishing satisfactory immunisation coverage in the dog population in view of the high proportion of stray dogs. Oral vaccination may be a useful adjunct to parenteral vaccination by increasing dog vaccination coverage. Safety, immunogenicity and efficacy of Rabidog SAG2 bait were evaluated in Indian stray dogs in captivity. Safety of SAG2 was demonstrated by the absence of adverse clinical sign, salivary excretion and absence of replication of the vaccine strain in brain and salivary glands of 21 vaccinated dogs, even when immunodepressed. Efficacy was shown 109 days post-vaccination after challenge with a highly virulent street rabies virus which killed all five controls whereas all nine vaccinated dogs survived, despite the fact that only five out of nine had seroconverted before challenge.

Abstract
AIMS To examine the potential of Lactobacillus delbrueckii mutant, Uc-3 to produce lactic acid and fructose from sucrose-based media. METHODS AND RESULTS The mutant of L. delbrueckii NCIM 2365 was cultivated in shake flask containing hydrolysed cane sugar (sucrose)-based medium. The lactic acid yield and volumetric productivity with hydrolysed cane concentration up to 200 g l(-1) were in the range of 92-97% of the theoretical value and between 2.7 and 3.8 g l(-1) h(-1), respectively. The fructose fraction of the syrup produced was more than 95% when the total initial sugar concentration in the medium was higher (150-200 g l(-1)). There are no unwanted byproducts detected in the fermentation broth. CONCLUSIONS We demonstrated that L. delbrueckii mutant Uc-3 was able to utilize glucose preferentially to produce lactic acid and fructose from hydrolysed cane sugar in batch fermentation process. SIGNIFICANCE AND IMPACT OF THE STUDY These findings will be useful in the production of lactic acid and high fructose syrups using media with high concentrations of sucrose-based raw materials. This approach can lead to modification of the traditional fermentation processes to obtain value-added byproducts, attaining better process economics.

Abstract
Thirteen BVDV isolates collected in four geographic regions of India between 2000 and 2002 were typed in 5'-UTR. To confirm results of genetic typing, selected viruses were also analysed in the N(pro) region. Phylogenetic analysis revealed that all Indian BVDV isolates belong to BVDV-1b (Osloss-like group). Despite a long distance between the farms from which the viruses were isolated there was no correlation between the origin of viral isolates and their position in a phylogenetic tree. Higher genetic similarity of Indian BVDV isolates was observed most probably due to the uncontrolled movement of cattle as well as the uncontrolled use of semen from bulls for breeding of local and farm cattle in different states of India.

Abstract
BACKGROUND Hypothyroidism is a common, potentially treatable endocrine disorder. Since hypothyroidism is not always associated with the signs and symptoms typically attributed to it, the diagnosis is often missed. Conversely, patients with typical signs and symptoms may not have the disease when laboratory tests are performed. AIMS We aimed to determine the accuracy of physical examination in the diagnosis of hypothyroidism. SETTING AND DESIGN Prospective, hospital-based, cross-sectional diagnostic study. MATERIAL AND METHODS Consecutive outpatients from the medicine department were screened and an independent comparison of physical signs (coarse skin, puffy face, slow movements, bradycardia, pretibial oedema and ankle reflex) against thyroid hormone assay (TSH and FT4) was performed. STATISTICAL ANALYSIS Diagnostic accuracy was measured as sensitivity, specificity, positive likelihood ratios, negative likelihood ratios and positive and negative predictive values. RESULTS Of the 1450 patients screened, 130 patients (102 women and 28 men) underwent both clinical examination and thyroid function tests. Twenty-three patients (18%) were diagnosed to have hypothyroidism by thyroid hormone assays. No single sign could easily discriminate a euthyroid from a hypothyroid patient (range of positive likelihood ratio (LR+) 1.0 to 3.88; range of negative likelihood ratio (LR-): 0.42 to 1.0). No physical sign generated a likelihood ratio large enough to increase the post-test probability significantly. The combination of signs that had the highest likelihood ratios (coarse skin, bradycardia and delayed ankle reflex) was associated with modest accuracy (LR+ 3.75; LR- 0.48). CONCLUSION Clinicians cannot rely exclusively on physical examination to confirm or rule out hypothyroidism. Patients with suspected hypothyroidism require a diagnostic workup that includes thyroid hormone assays.

Abstract
The in vitro degradation of microspheres of polymers of lactic and glycolic acids were investigated by monitoring the mass loss from the device, the molecular weight of the polymer and the morphological changes of the particles with time. Two different sequences of morphological changes were found to be operative, depending upon the polymer from which they were made--one, (I) for the high molecular weight P(DL)LA, and the other, (II) for all PLGAs and the low molecular weight P(DL)LA. Microspheres of category I showed clear evidence of heterogeneous degradation, where the initially dense microsphere developed a hollow interior. Microspheres of category II plasticized on hydration due to reduction in the Tg of the polymer below the incubation temperature of 37 degrees C. There was suppression of release of entrapped globular proteins from microspheres that underwent plasticization (category II), while slow and sustained release was seen from those that did not (category I). It is proposed that plasticization renders the matrix of category II microspheres non-porous, which prevents release by pore-diffusion. The mass loss profiles of PLGA were found to be different from those reported in the literature, in that the rates of mass loss after an initial lag time were not as rapid as has been reported. The experimental conditions used, namely the use, or otherwise, of agitation, is suggested as the reason for these differences and the need to draw a correlation between in vitro experimental conditions and in visa behaviour is emphasized.

Abstract
Twenty-three foot-and-mouth disease virus (FMDV) type A field isolates, recovered from different outbreaks during 1987-1996 in India, were subjected to antigenic and genetic analysis. The isolates showed a close antigenic relationship to the current vaccine strain (IND 17/77) in micro-neutralization test conducted using a vaccine strain (IND 17/77) antiserum and a peptide (aa 136-151 of VP1 protein of the A22/Azerbaijan/65 strain) antiserum. However, the isolates revealed minor antigenic differences in their reactivity with three neutralizing monoclonal antibodies (MAbs) recognizing trypsin-sensitive conformation-independent epitopes of the vaccine virus strains. Phylogenetic relationship between the isolates was carried out employing a part of the 1D gene (168 nucleotides at the 3'-end). Additional seven type A Indian field isolates reported earlier were included in the analysis. The percent similarity among the Indian isolates varied from 82.7% to 99.4% at nucleotide level, and from 83.9% to 100% at amino acid level. These observations clearly demonstrate genetic heterogeneity of the field isolates. The current vaccine strain IND 17/77 showed divergence of 9.7% at nucleotide level and 5.6% at amino acid level from the A22 Iraq 24/64 isolate. The field strains were divergent from the vaccine strain IND 17/77 by 5.6%-14.6% and 3.7% 13.7% at nucleotide and amino acid level, respectively. In the phylogenetic tree, the isolates were distributed into 21 genetic groups. The clustering pattern of the isolates in the phylogenetic tree revealed no specific distribution pattern of the foot-and-mouth disease (FMD) outbreaks in relation to their geographical locations, caused by unrestricted animal movement and endemic nature of the disease.

Abstract
The phaseolotoxin-resistant ornithine carbamoyltransferase (ROCT) and phaseolotoxin are produced by Pseudomonas syringae pv. phaseolicola at 18 degrees C but not at 28 degrees C. At 28 degrees C, the pathogen produces a protein(s) that binds (in vitro) to a 485-bp fragment (thermoregulatory region, TRR) from a heterologous clone from the pathogen genomic library, which in multiple copies overrides thermoregulation of phaseolotoxin production in wild-type cells (K. B. Rowley, D. E. Clements, M. Mandel, T. Humphreys, and S. S. Patil, Mol. Microbiol. 8:625-635, 1993). We report here that DNase I protection analysis of the 485-bp fragment shows that a single site is protected from cleavage by the protein in the 28 degrees C extract and that this site contains two repeats of a core motif G/C AAAG separated by a 5-bp spacer. Partially purified binding protein forms specific complexes with a synthetic oligonucleotide containing four tandem repeats of this motif. A 492-bp upstream fragment from argK encoding ROCT also forms specific complexes with the protein in the 28 degrees C crude extract, and a 260-bp subfragment from the TRR containing the binding site cross competes with the argk fragment, indicating that the same protein binds to nucleotides in both fragments. DNase I protection analysis of the fragment from argK revealed four separate protected sequence elements, with element III containing half of the core motif sequence (CTTTG), and the other elements containing similar sequences. Gel shift assays were done with DNA fragments from which one or all of the sites were removed as competitor DNAs against the argK probe. The results of these experiments confirmed that the binding sites (in argK) are necessary for the protein to bind to the argK fragment in a specific manner. Taken together, the results of studies presented here suggest that in cells of P. syringae pv. phaseolicola grown at high temperature argK may be negatively regulated by the protein produced at this temperature.

Abstract
A cluster of genes involved in the production of phaseolotoxin, a phytotoxin produced by Pseudomonas syringae pv. phaseolicola, contains eight (phtA through phtH) complementation groups (Y. X. Zhang, K. B. Rowley, and S. S. Patil, J. Bacteriol., 175:6451-6458, 1993). In this study, sequencing of the region encompassing the phtE locus revealed six putative open reading frames (ORFs), each preceded by a putative ribosomal binding site, and all oriented in the same direction. Reverse transcription-polymerase chain reaction suggested that the phtE locus is transcribed as one large (6.4 kb) transcript, indicating that the ORFs constitute an operon. Primer extension analysis showed that the transcript begins at a T, located 31 bp upstream of the ATG codon of ORF1. Comparison of the sequences of the putative ORFs with the sequences of known genes revealed that ORF3, encoding a protein containing 395 amino acids, has 55% similarity to the acetylornithine aminotransferase gene from Escherichia coli, and the ornithine aminotransferase genes from other organisms. A lysine residue that is a binding site for pyridoxal phosphate and an arginine residue that is a binding site for the alpha-carboxylate group of the substrate are conserved in ORF3. These data suggest that ORF3 encodes a protein involved in the biosynthesis of ornithine, a constituent of phaseolotoxin. ORF5, encoding a peptide of 378 amino acid residues, possesses a helix-turn-helix motif at the C-terminal end that is characteristic of the AraC family of transcriptional factors, and there is a possible leucine zipper at the N-terminal end of this peptide. ORF6, encoding a protein of 327 amino acids, has about 40% similarity with the fatty acid desaturase gene, desA, of Synechocystis Pcc6803 and considerable similarity with fatty acid desaturase genes from other organisms. ORF6 and desA show very similar hydropathy profiles and both contain a copper binding signature. Computer searches did not discover significant homologies in the data base for the other ORFs, but hydropathy analysis showed that all of them contain one to several hydrophobic domains, suggesting that the gene products of these ORFs may be membrane associated.

Abstract
We describe three cases of traumatic myositis ossificans in which fractures occurred through a mature, quiescent ossification mass. None of the fractures reactivated the original pathological process, no callus was formed and union did not occur. The nonunion became painless over a period of months. This unusual late complication of myositis ossificans seems to require only symptomatic treatment by temporary splintage and subsequent mobilisation. We could find no previous report of a similar case.

Abstract
Phaseolotoxin [N delta(N'-sulfo-diaminophosphinyl)-ornithyl-alanyl- homoarginine] produced by Pseudomonas syringae pv. phaseolicola, the bean halo blight pathogen, is a potent inhibitor of ornithine carbamoyltransferase (OCT). Inhibition of OCT in infected plants leads to chlorosis and growth inhibition. A genomic cosmid clone, pHK120, containing a 25-kb fragment of DNA from a wild-type strain of P. syringae pv. phaseolicola restores toxin production in Tox- mutants. Tn5 mutagenesis of pHK120 and marker exchange of pHK120::Tn5 plasmids in the wild-type strain resulted in the isolation of 39 chromosomal mutants that harbor Tn5 insertions at known positions. Toxin bioassays revealed that 28 of the mutants, with Tn5 insertions distributed throughout the insert of pHK120, were Tox-, indicating that a functional locus for toxin production in each mutant was inactivated. Complementation analysis was done by testing for toxin production strains that carried a genomic Tn5 at one location and a plasmid-borne Tn5 at another location (pair complementation). Pair complementation analysis of nine marker exchange mutants and a random genomic Tn5 mutant revealed that there are a minimum of eight toxin loci (phtA through phtH) in pHK120. Mutants carrying Tn5 insertions in the phtA, phtD, and phtF loci were complemented by deletion subclones containing fragments from pHK120; mutants carrying Tn5 insertions in the phtC locus were partially complemented by a subclone, and mutants carrying Tn5 insertions in the phtB, phtE, phtG, and phtH loci were not complemented by any of the available subclones. A comparison of the insert from pHK120 with that from pRCP17, a clone reported previously (R. C. Peet, P. B. Lindgren, D. K. Wills, and N. J. Panopoulos, J. Bacteriol. 166:1096-1105, 1986) by another laboratory to contain some of the phaseolotoxin genes and the phaseolotoxin-resistant OCT gene, revealed that the inserts in these two cosmids overlap but differ in important respects.

Abstract
Phaseolotoxin, a phytotoxin of Pseudomonas syringae pv. phaseolicola, is produced at 18 degrees C but not at 28 degrees C. Here we report that a fragment (24.4 kb) cloned from the wild-type strain, which does not harbour a gene(s) involved in phaseolotoxin biosynthesis, abolishes this thermoregulation in the wild type and suppresses a Tox- mutant at both temperatures. A subclone harbouring a 485 bp fragment contains motifs that are characteristic of DNA-binding sites. In mobility shift assays we have detected a protein(s) from the wild-type and the mutant strains, grown at appropriate temperatures, that specifically binds to the fragment containing the DNA-binding motifs. We propose that the binding protein is a repressor which is 'titrated' by this fragment when it is present in the cell on a multiple copy plasmid, thus allowing expression of phaseolotoxin genes.

Abstract
Cytochrome P-450 has been purified from goat and chick erythrocytes and characterized. Goat erythrocyte cytochrome P-450 content was higher than that of chick erythrocytes cytochrome P-450. Elution profile of purified protein from DEAE-cellulose column showed a single peak. The catalytic activities of aminopyrine-N-demethylase and acetanilide hydroxylase were found to be higher in purified proteins. Molecular weight was determined by SDS-polyacrylamide gel electrophoresis.

Abstract
Many peptide antibiotics in prokaryotes and lower eukaryotes are produced non-ribosomally by multi-enzyme complexes. Analysis of gene-derived amino acid sequences of some peptide synthetases of bacterial and fungal origins revealed a high degree of conservation (35-50% identity). The genes encoding those peptide synthetases are clustered into large operons with repetitive domains (about 600 amino acids), in the case of synthetases activating more than one amino acid. We used two 35-mer oligonucleotides derived from two highly conserved regions of known peptide synthetases to identify the surfactin synthetase operon in Bacillus subtilis ATCC 21332, a strain not accessible to genetic manipulation. We show that the derived oligonucleotides can be used not only for the identification of unknown peptide synthetase genes by hybridization experiments but also in sequencing reactions as primers to identify internal domain sequences. Using this method, a 25.8-kb chromosomal DNA fragment bearing a part of the surfactin biosynthesis operon was cloned and partial sequences of two internal domains were obtained.

Abstract
The biodegradation of nitrobenzene (NB) and 2,4-dinitrophenol (DNP) in NB plant wastewater has been studied using acclimated activated sludge in a batch bioreactor. The gas chromatographic (GC) monitoring shows simultaneous utilization of these two substrates, and both NB and DNP were ultimately biodegraded. The primary and ultimate biodegradation rates using GC and COD methods, respectively, are compared and reported.

Abstract
Chlorosis-inducing isolates of Xanthomonas albilineans, the sugarcane leaf scald pathogen, produced a mixture of antibacterial compounds in culture. The antibiotic mixture, which eluted as a single strongly retarded peak from Sephadex LH-20 in methanol, was bactericidal to Escherichia coli. Inhibition of E. coli was not reversed by added nutrients, and affected cells were not lysed but many accumulated polyphosphate granules. The major antibacterial component, isolated in crystalline form after HPLC, is given the trivial name albicidin. Near the minimum inhibitory concentration, albicidin caused a complete block to DNA synthesis, followed by partial inhibition of RNA and protein synthesis, as assessed by incorporation of radioactive precursors. Spontaneous antibiotic-resistant mutants of E. coli showed no cross-resistance between albicidin and inhibitors of either subunit of DNA gyrase. Mixing albicidin with purified DNA from E. coli did not alter the thermal denaturation behaviour of the DNA, or the absorption spectrum of the antibiotic. PolA+ and PolA - strains of E. coli were equally sensitive to albicidin, indicating that the antibiotic does not bind to or modify DNA. Selective inhibition of DNA synthesis without evidence of DNA binding suggests a specific interaction of albicidin with an essential replication protein.
